To program your air conditioning to be at the temperature you want before you even get home. You will have the ability to adjust it from a simple app. Your home to your liking.

Your air conditioner according to the size of your room

Depending on the type of house you have and the layout of the house there are several options for air selection. If you do not have a previous installation for the air conditioning ducts in your home, the most recommended solution is to install fixed air conditioners.

When deciding on one model or another, we must know the surface area of the rooms to determine the power of the device and its consumption.

The power of the equipment is determined by the square metres of the room. For example, for a room of 30m2 we will need an appliance of 3000 and 4000 frigories, or 3.48 W/h and 4.65 W/h respectively.

ROOM TO BE COVERED ( m^2 ) FRIGORIES CALORIES
Up to 40m^2 5.000 Frigorías / h 6.000 kcal/h
Up to 60m^2 7.000 Frigorías / h 8.000 kcal/h
Up to 70m^2 18.000 Frigorías / h 20.000 kcal/h
Up to 90m^2 24.000 Frigorías / h 26.000 kcal/h
Up to 140m^2 36.000 Frigorías / h 40.000 kcal/h

Which type of air conditioner is most efficient and powerful for your home?

To find out the consumption of the appliance, we will be guided by the energy efficiency label. energy efficiency label:

  1. Product
  2. Model
  3. Energy classification
  4. Annual energy consumption by geographical area
  5. Cooling capacity
  6. SEER:

Seasonal energy efficiency in cooling. This figure compares the energy efficiency of air conditioning systems. The more kilowatts generated per kilowatt consumed, the more efficient an air conditioner is.

When the SEER is greater than 8.5, the air is class A+++ (the most efficient). Conversely, if the SEER is between 3.1 and 3.6, the air is E-class.

  1. Heating capacity

  2. SCOP:

Seasonal heat energy efficiency. This data compares the energy efficiency between heating systems.

When the SCOP is higher than 5.1, the air is class A+++ (the most efficient). On the other hand, if the SCOP is

On the other hand, if the SCOP is between 2.2 and 2.5, the air is class E.

  1. Noise level of the indoor and outdoor unit

How do I calculate consumption and power?

We should choose an air conditioner that is efficient because we will consume less energy, save on our electricity bill and take care of the environment.

Consumption can be calculated by dividing the power of the appliance by the SEER code or by the SCOP.

An example for an appliance with a power of 3,500W (3,000 frigories) and a SEER of 5.1:

If we switch on the equipment 4 hours a day during a summer month the cost will be €12.35*, i.e. about €0.10* per hour (*taking the cost per kW/h at €0.15).

3,500 watts/5.1 (SEER)=686 watts/hour.

(0,686kW/h x 0,15€)/1kW = 0,1029€ ; 0,1029€ x 4h x 30days = 12,348€.

To know the power, calculate approximately between 100 and 140 frigories per m2, depending on whether your house is more or less protected from cold and heat.

It also depends on the orientation, North or South, and the number of electronic devices in the room. For example, in a 20 m2 living room facing south, which is located in an area with temperatures that tend to exceed 30°C, you would have to calculate 140 frigories per square metre. The result would be 3250W or 2800 frigories.

Important safety instructions for GAS containing devices

Workplace checks.

Before starting work on installations containing flammable refrigerants, safety checks must be carried out to ensure that the risk of fire is minimised. In the case of refrigeration system repair, the following precautions should be taken before carrying out any work on the installation.

Work procedure

Work should be carried out under a controlled procedure to minimise the risk of flammable gases or vapours being present while the work is being carried out.

Work area.

All maintenance personnel and others working in the area must be informed of the nature of the work being carried out. Avoid working in enclosed spaces.

Check for the presence of refrigerant

Before and during work, the area should be checked with a suitable refrigerant detector to ensure that the technician is aware of the existence of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, properly sealed or intrinsically safe.

Presence of a fire extinguisher.

If any work is to be carried out on the refrigeration equipment or any part thereof, suitable fire extinguishing equipment must be available. Have a dry powder or CO2 fire extinguisher next to the loading area.

There are no sources of ignition.

No person performing work in connection with a refrigeration system involving exposure of any piping shall use sources of ignition in such a manner as to cause a fire or explosion. All possible sources of ignition, including cigarette smoking, shall be kept sufficiently far away from the installation, repair, removal and disposal site, during which time refrigerant may be released into the surrounding space. Before work is carried out, the area around the equipment must be inspected to ensure that there are no ignition hazards or ignition risks. No smoking" signs shall be posted.

Ventilated area.

Ensure that the area is in the open air or adequately ventilated before accessing the system or performing any hot work. A certain degree of ventilation must be maintained during the work period. Ventilation should safely disperse any refrigerant that is released and preferably expel it outside into the atmosphere.

Checking refrigeration equipment.

When electrical components are replaced, they should be fit for purpose and to the correct specification. The manufacturer's maintenance and service guidelines shall be followed at all times. If in doubt, consult the manufacturer's technical department for assistance. The following controls shall apply to installations using flammable refrigerants.

Checks of electrical devices.

Repair and maintenance of electrical components should include initial safety checks and component inspection procedures. If there is a fault that could compromise safety, no electrical supply should be connected to the circuit until it is satisfactorily resolved. If the fault cannot be corrected immediately, but continued operation is necessary, a suitable temporary solution must be used. This shall be communicated to the owner of the equipment so that all parties are informed.

Initial safety checks shall include:

  • that capacitors are discharged: this must be done in a safe manner to avoid the possibility of sparking;
  • that no electrical components or wiring are exposed while charging, recovering or purging the system;
  • That there is continuity of grounding.

Repair of sealed components.

During repairs to sealed components, all electrical supplies should be disconnected from the equipment being worked on before removing sealed covers, etc. If it is absolutely necessary to have power supply to the equipment during repairs, permanent leak detection must be carried out. This should be done at the most critical point to warn of a potentially dangerous situation.

Particular attention must be paid to the following to ensure that, when working with electrical components, the enclosure is not altered in such a way as to affect the level of protection. For example, damage to cables, excessive number of connections, terminals not made to the original specification, damage to seals, incorrect mounting of bushings, etc.

Ensure that the product is properly assembled.

Ensure that gaskets or sealing materials have not degraded to the point where they are no longer suitable for preventing the ingress of flammable atmospheres. Spare parts must conform to the manufacturer's specifications.

Repair of intrinsically safe components.

Do not apply any permanent inductive or capacitive load to the circuit without ensuring that it will not exceed the permissible voltage and current for the equipment in use.

Intrinsically safe components are the only ones that can be worked on in the presence of a flammable atmosphere. Test apparatus must be in the correct classification.

Replace components only with parts specified by the manufacturer. Other parts may cause ignition of the refrigerant in the atmosphere due to leakage.

Wiring

Check wiring for wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check should also take into account the effects of ageing or continuous vibration from sources such as compressors or fans.

Detection of flammable refrigerants.

Under no circumstances should potential ignition sources be used when searching for or detecting refrigerant leaks. A halide torch (or any other detector using an open flame) must not be used.

Extraction and evacuation

When entering the refrigerant circuit for repairs, or for any other purpose, conventional procedures should be used. However, in the case of flammable refrigerants it is important that the procedure is the most appropriate, as combustion is a factor to be taken into account. The following procedure should be followed:

remove the refrigerant

purge the circuit with inert gas

evacuate

purge with inert gas

Open the circuit by cutting or welding

The refrigerant charge shall be recovered in suitable recovery cylinders. For products containing flammable refrigerants, the system must be purged with oxygen-free nitrogen to make the product safe for flammable refrigerants. This process may need to be repeated several times. Compressed air and oxygen should not be used to purge refrigerant systems.

For products containing flammable refrigerants, refrigerant flushing should be performed by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until working pressure is reached, then venting to atmosphere and finally lowering to vacuum. This process must be repeated until there is no refrigerant in the system. When the final charge of oxygen-free nitrogen is used, the system must be vented to atmospheric pressure in order to perform the work. This operation is absolutely vital for brazing operations performed on piping.

Make sure that the vacuum pump outlet is not close to any possible source of ignition and that ventilation is available.

Charging procedures

In addition to conventional charging procedures, the following requirements must be followed:

Ensure that you do not contaminate yourself with different refrigerants when using the charging equipment. Hoses or lines should be kept as short as possible to minimise the amount of refrigerant they contain.

Cylinders should be kept in the proper position according to the instructions.

Ensure that the refrigeration system is grounded before charging with refrigerant.

Label the equipment when charging is complete (if not already done).

Great care must be taken not to overcharge the refrigeration system.

Note: Before refilling the system, the system shall be pressure tested with the appropriate purge gas. The system shall be leak tested at the end of charging but before commissioning. A follow-up leak test shall be carried out before leaving the site.

Disassembly

Before carrying out this procedure, it is essential that the technician has a thorough knowledge of the equipment and all its details. It is recommended as good practice that all refrigerants are safely recovered. Before carrying out the task, a sample of oil and refrigerant should be taken in case an analysis is required before reusing the recovered refrigerant. It is essential that electrical power is available before starting the task.

Familiarise yourself with the equipment and its operation.

Electrically isolate the system.

Before attempting the procedure, ensure that technical equipment is available for handling refrigerant cylinders, if necessary;

Pump out the refrigerant system, if possible.

If vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

Make sure that the cylinder is placed on the scale before recovery.

Start the recovery machine and operate it according to the instructions.

Do not overfill the cylinders (no more than 80% of the liquid charge volume).

Do not exceed the maximum working pressure of the cylinder, even temporarily.

When the cylinders have been correctly filled and the process has been completed, ensure that the cylinders and equipment are removed from the site promptly and that all isolation valves on the equipment are closed.

Recovered refrigerant should not be charged to another refrigeration system unless it has been cleaned and checked.

Labelling

Equipment shall be labelled indicating that it has been decomposed and drained of refrigerant. The label shall be dated and signed. In the case of equipment containing flammable refrigerants, it shall be ensured that there are labels on the equipment indicating that the equipment contains flammable refrigerant.

Recovery

When refrigerant is removed from a system, either for service or for shutdown, it is recommended as good practice that all refrigerants are disposed of safely.

When transferring refrigerant to cylinders, ensure that only suitable refrigerant recovery cylinders are used. Ensure that the correct number of cylinders are available to maintain the total system charge. All cylinders used are designated for the refrigerant recovered and labelled for that refrigerant (i.e. special refrigerant recovery cylinders). Cylinders must be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled prior to recovery.

Recovery equipment must be in good working order, with a set of equipment instructions at hand, and must be suitable for the recovery of all appropriate refrigerants, including, where appropriate, flammable refrigerants. In addition, a set of calibrated scales in good working order shall be available. Hoses shall be complete with disconnect couplings free of leaks and in good condition. Before using the recovery machine, check that it is in good working order, that it has been properly maintained and that all associated electrical components are sealed to prevent ignition in the event of refrigerant discharge.

Consult the manufacturer if in doubt. Recovered refrigerant shall be returned to the refrigerant supplier at the correct recovery site.

A: Low pressure shut-off valve

B: High pressure shut-off valve

C and D: Indoor unit flare nuts

Wiring installation

  1. Ensure the following when long pipes are to be welded.

a) Fully install the piping and any welding work before connecting the piping to the unit.

b) Oxygen-free nitrogen should be used inside the pipes to prevent rusting.

  1. If there are many joints requiring brazing during installation of long pipes, use an in-line filter. All tubing should be of good quality refrigeration grade dehydrated copper and not normal plumbing grade copper and should be free of moisture, dust or other contaminants.

  2. Please purge the tubing with nitrogen or to remove any dust inside before oxidation.

  3. Please install the pipe according to the direction of the pipe, and do not repeatedly bend and then straighten a piece of pipe more than 3 times (this will damage the copper). Use a pipe bender to bend the pipe. After preparing a length of pipe, slide the pipe insulation material over it.

  4. Once the pipe connection is completed, connect the pipe to the indoor unit using the supplied connection connector. Disconnect the valve fixing nut from the indoor unit and place it on the piping facing the indoor unit. Fix the piping as shown in this manual, and after coating both the flare nut and the inside and outside of the flare with a light coat of refrigerant oil, tighten the nut using a wrench to tighten the nut and a spanner to hold the valve on the unit. Always use a wrench with the correct tightening torque and always fasten the indoor unit valve with another spanner. Do not over-tighten or under-tighten the torque. This process is done for both small and large pipes.

  5. Connect to the outdoor unit in a similar manner.

  6. Once the piping connection is completed, carry out a full tightness test on the piping and make sure that there are no leaks in the piping and connections and that everything is fully insulated.

Thermal insulation and tightness

The copper pipe and the drain pipe must be insulated separately to prevent condensation or water leakage.

  1. The copper pipe must be properly insulated using materials designed for insulating air-conditioning pipes and resistant to heat above 120^ C.

  2. Issues requiring attention in areas with a very high humidity level:

The air conditioner has been tested in various humidity conditions. However, if it is operated for long periods of time in an environment with a high level of humidity, water droplets will be produced, so the following thermal insulation should be carried out.

a) The indoor unit should be externally insulated with 10-20 mm thick glass fibre.

b) Normal pipe insulation is about 8 mm for pipes.

  1. Wall sealing:

To prevent rainwater or other foreign bodies from entering the room and air conditioner after installing the pipe and drain pipe, the gap between the hole in the wall and the pipe, drain pipe and electric wire should be sealed with putty, rubber sealant or mastic, or poor performance or leakage will occur. If the outdoor unit is higher than the indoor unit, the pipe should be bent to ensure that the lowest point of the pipe is lower than the hole in the wall to prevent rainwater from entering the room or air conditioner along the piping system.

  1. The air outlet connection must be insulated.

  2. The air outlet pipes are connected under insulation.

Refrigerant gas pipe connection

The standard length of the refrigerant pipe is 5m. If the distance between inside and outside is greater than this, it will be necessary to extend the pipe.

Refer to the table below for the limitations of each unit in terms of maximum distance and height.

Do not exceed these limits or compressor failure may occur.

Keep the pipe separation length and number of elbows to a minimum and always follow the shortest route for pipe installation.

As pipe length and number of elbows increase, unit performance decreases and energy consumption increases.

As refrigerant pipe only phosphor copper pipe, deoxidised, seamless, of suitable quality for R410a must be used.

-Requirements for the connection pipe between the indoor unit and the outdoor unit:

  1. The machining dimension of the flared pipe section is as shown in the following table;

  2. When connecting the flare nut, refrigerant oil should be applied on the flare pipe section (both inner and outer wall), and screw the nut by screwdriver for 3-4 thread steps before finally tightening the nut; 3. The tightening torque is shown in the following table;

  3. Carry out the leakage test after completion of installation.

19.05mm98-120 N·m22.9-23.3

Precautions:

  1. Horizontal piping should slope towards the outdoor unit with a slope of 20:1.

  2. If there is a height difference between the indoor and outdoor unit, oil traps should be installed in the gas interconnection pipe (large):

When the vertical pipe height difference is less than 5m, an oil trap should be installed at the bottom of the gas pipe (large). When the vertical pipe height difference is more than 5m, an oil trap must be installed at the bottom of the gas pipe (large) and a short ring must be installed at the outlet of the liquid pipe (small) of the indoor unit every 5m:

When the vertical height difference of the connecting gas pipe is less than 5m, but the constant rise distance is too long, an oil trap should be installed on the (large) gas pipe every 10m.

  1. When the outdoor and indoor units are at the same elevation, it is not necessary to install the oil reservoir elbow and liquid ring, if the horizontal length of the connecting pipe is less than 10m. When the horizontal connecting pipe length is longer than 10m, install an oil sump on the gas pipe (large) every 10m.

Note: This table is for explanatory purposes. An actual installation may differ from this and must take into account the site conditions. When making an oil trap, the radius of the bend should be between 1.5 and 2 times the pipe diameter.

Connecting the pipe and indoor unit

Remove the copper nut from the indoor unit and insert it onto the unflare pipe before making the fitting, align the flare side of the connecting pipe with the indoor unit connector, lightly coat the fitting and nut with refrigerant oil, screw the copper nut onto the indoor unit connector and tighten it (the tightening torque is shown in the table above).

Connecting the piping and outdoor unit

Follow the instructions for flaring the indoor unit as shown in Fig:

Flaring nut Connecting pipe Big pipe (gas pipe) Small pipe Connector

Installing the draining pipe

To ensure that the drained water drains properly, the unit must be tilted towards the bottom of the unit after installation is complete.

  1. The drain hose must be wrapped with thermal insulation to insulate it properly and prevent ice build-up.

  2. The pipe should be installed with a downward slope (>1/1.36) to allow water drainage.

  3. The pipe must not be elevated at any point.

Evacuate or flush pipes

Before releasing the refrigerant from the outdoor unit into the pipes and the indoor unit, it is necessary to ensure that there are no foreign objects, water or non-condensing gas in the refrigeration system. For this purpose, it is necessary to evacuate or purge the system:

A dedicated R32 refrigerant pump must be used to make the R32 refrigerant vacuum. Before working on the air conditioner, remove the shut-off valve cap (gas and liquid valves) and be sure to retighten it afterwards (to avoid possible air leakage).

  1. To prevent air leakage and spillage, tighten all connection nuts on all pipes.

  2. Connect the shut-off valve, the charging hose, the manifold valve and the vacuum pump.

  3. Fully open the manifold valve and apply a vacuum for at least 15 minutes and check that the vacuum hose

15 minutes and check that the vacuum gauge on the equipment indicates -0.1 MPa(-76cmHg).

  1. After applying vacuum, fully open the shut-off valve with a hex spanner.

  2. Check that the internal and external connections are free of air leaks.

Adjusting the refrigerant quantity

When the pipe length exceeds 5m, add refrigerant according to the table below:

Refrigerant pipeRefrigerant pipeAdditional charge (Kg/m)
Gas (mm) Liquid (mm)
Pipe between indoor unit and outdoor unit9.52x0.75 6.385x0.75 0.033
12.7x1 6.35x0.75 0.03
15.88x1 9.52x0.75 0.05
19.05x1 9.52x0.75 0.05

Note:

  1. This table is for guidance only.

  2. Joints shall not be reused except after re-flaring the pipe.

  3. After installation, check that the shut-off valve cover is securely fastened.

  4. The pipe thickness is 0.6-1.0, the bearing pressure is 4.2MPa.

  5. If the connection pipe is too long, the cooling capacity and stability will decrease. The larger the number of bends, the higher the resistance in the piping system, which will reduce the cooling and heating capacity and even lead to breakage.

This will reduce the cooling and heating capacity and even lead to compressor breakage. If the height difference between the indoor and outdoor unit is more than 5m, an oil sump must be installed in the an oil trap must be installed in the gas pipe every 10m.

  1. Please add refrigerant according to the liquid piping.

Electrical installation

The interconnection cable connects the indoor and outdoor units. You must first choose the correct cable size before preparing it for connection.

Then choose the minimum cross-section of the power cable and the interconnecting cable.

Rated product current (A) Nominal section (mm 2)
>3 / ≤ 6 0.75
>6 / ≤10 1
>10 / ≤16 1.5
>16 / ≤25 2.5
>25 / ≤32 4
>32 / ≤40 6

The size of the interconnecting cable, power cord, fuse and circuit breaker required is determined by the maximum current of the unit. The maximum current is indicated on the nameplate located on the side panel of the unit.

Refer to this nameplate to select the appropriate cable, fuse or circuit breaker.

Note: The cable core number refers to the detailed wiring diagram attached to the unit you have purchased.
