Desuperheater Option

The desuperheater option is a heat recovery system packaged within the water-to-water unit. This option captures heat energy from the heat pump for considerable cost savings all year. Since it is active in either operating mode, it can provide hot water at a reduced cost while in heating or virtually free hot water while in cooling.

Standard equipment includes:

θDesuperheater (heat exchanger)

θCirculating pump

θEntering water temperature detector (125 F stops pump)

θDischarge refrigerant temperature detector (145 F starts pump)

θFuse

θWater heater hook-up kit

The unit employs a circulating pump to move water through a double wall heat exchanger. It then returns the heated water to the water tank. This water is heated by superheated re- frigerant discharge gas from the compressor. This heat energy can now be utilized as a cost savings in water heating.

Circulating Pump

The pump is a circular, single stage open system pump. Its specifica- tions include:

θ1/25 HP (horsepower)

θ230 Volt / 60 Hertz / 1 phase

θ90 Watts

θ.40 Amps

θ2865 rpm (revolutions per minute)

θ2 MF (microfarad) / 400 Volt capacitor

The pump contains a minimum fluid temperature rating of 50 F, a maxi- mum fluid temperature (open sys- tem) of 140 F, and a maximum working pressure of 145 psi.
