GT-PW Water-To-Water (50YER) Series Features

The GT-PW Water-To-Water (50YER) Series

The 50YER water-to-water series offers high efficiency with advanced features, extremely quiet operation and application flexibility at competitive prices. As Carrier's most adaptable Puron® HFC-410A refrigerant units, the 50YER series can be used for radiant floor heating, snow/ice melt, chilled water for fan coils, potable hot water generation, hot/chilled water for make-up air, and many other types of HVAC applications.

Available in sizes 036 [8.7 kW], 060 [13.5 kW] and 120 [26.9 kW] the 50YER series offers a wide range of units for most any installation. The 50YER has an extended range refrigerant circuit, capable of ground loop (geothermal) applications as well as water loop (boiler-tower) applications. Standard features are many. Microprocessor controls, galvanized steel cabinet, powder coat paint, stainless steel front access panels and TXV refrigerant metering device are just some of the features of the flexible 50YER series.

A double isolation compressor mounting system facilitates quiet operation. Compressors are mounted on vibration isolation grommets to a heavy gauge mounting plate, which is then isolated from the cabinet base with rubber grommets for maximized vibration/sound attenuation. Optional double-wall load heat exchanger (for potable hot water generation) allows customized design solutions.

The 50YER Series water-to-water heat pumps are designed to meet the challenges of today's HVAC demands with a high efficiency, high value solution.

Performance Data Selection Notes

For operation in the shaded area when water is used in lieu of an anti-freeze solution, the LWT (Leaving Water Temperature) must be calculated. Flow must be maintained to a level such that the LWT is maintained above 40^ [4.4^] when the JW3 jumper is not clipped (see example below). Otherwise, appropriate levels of a proper anti-freeze should be used in systems with leaving water temperatures of 40^ or below and the JW3 jumper should be clipped. This is due to the potential of the refrigerant temperature being as low as 32^ [0^] with 40^ [4.4^] LWT, which may lead to a nuisance cutout due to the activation of the Low Temperature Protection. JW3 should never be clipped for standard range equipment or systems without antifreeze.

Example:

At 50^ F EWT (Entering Water Temperature) and 1.5 ~gpm/ ton, a 3 ton unit has a HE of 22,500 Btuh. To calculate LWT, rearrange the formula for HE as follows:

HE = TD x GPM x 500, where HE = Heat of Extraction (Btuh); TD = temperature difference (EWT - LWT) and GPM = U.S. Gallons per Minute.

$$ T D = H E / (G P M \times 5 0 0) $$

$$ T D = 2 2, 5 0 0 / (4. 5 \times 5 0 0) $$

$$ T D = 1 0 ^ {\circ} F $$

$$ \mathrm {L W T} = \mathrm {E W T} - \mathrm {T D} $$

$$ \mathrm {L W T} = 5 0 - 1 0 = 4 0 ^ {\circ} \mathrm {F} $$

In this example, as long as the EWT does not fall below 50^ , the system will operate as designed. For EWTs below 50^ , higher flow rates will be required (open loop systems, for example, require at least 2 gpm/ton when EWT is below 50^ ).
