Water Cooled Heat Pump Operation

In one coil the refrigerant is evaporated at low pressure and absorbs heat from its surroundings.

Water cooled heat pump operation. The heat pump disconnect switch hpds must be closed to provide power to the heat pump. Dehumidification is also achieved on the cooling cycle by removal of moisture from the air in the form of condensate. The system combines conventional water cooled air conditioning and hydronic space heating all in one package. A compressor pumps the refrigerant between two heat exchanger coils.

It takes more power to pump the water through these channels than you extract from the. Water source heat pump consider installing water source heat pump as this is one of the most efficient system available today. A cgc hybrid unit operates as a fan coil in heating and a water cooled dx unit in cooling. Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of evaporation and condensation.

The cgc group hybrid heat pump system is a novel combination of two traditional commercial hvac building technologies. In a heat pump system including a water purifier and an evaporator for evaporating feed water to produce steam water used for spray cooling is effectively used and productivity of purified water used for the spray cooling is increased. From one medium to another. If multiple units of wshps are installed they can all be serviced by a common water loop system or header.

The remainder of the control system is powered by 120vac 15 amp circuit. The air to water heat pump and circulator p1 are powered by a dedicated 240 120vac 30 amp circuit. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. Discharged water from the water purifier is supplied to the evaporator when water used for spray cooling is produced by use of the water purifier.

Water for closed loop heat pumps is usually circulated at 2 25 to 3 00 gpm per ton of unit cooling capacity. This can get heat off the chip and initial implementations have found that there s a bit of a trade off. Water to air heat pump heat is rejected to the water from the air being conditioned cooled on the cooling cycle. Simultaneous cooling and heating can operate on the same system.

A water source heat pump extracts heat from the water when in the heating mode and rejects heat to the water when in the cooling mode. Heat pump thermostat a more detailed thermostat operation covered here.
