Water Source Heat Pump System Design

With electricity priced at 0 13 kwhr the annual savings in heating energy was about 142.

Water source heat pump system design. Figure 3 18 applied water source heat pump system. Commercial water source heat pumps can be applied to geothermal closed circuit or open well loops or on a traditional boiler tower loop system. From one medium to another. Carrier s commercial water source heat pumps wshp offer a wide selection of fan motor options from permanent split capacitor psc motors and constant airflow electronically commutated motors ecm.

The thermal storagereport provides an hourly profile of ambient conditions plant level cooling loads heat pump loads and energy consumption and condenser loop temperatures. Water for closed loop heat pumps is usually circulated at 2 25 to 3 00 gpm per ton of unit cooling capacity. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.

Each unit is an independent packaged system eliminating the chance of a total system failure. Energy conservation in new building design. The fluid absorbs this heat and boils even at temperatures below 0 c although the coefficient of performance cop decreases with lower temperature. 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 design guide there are multiple benefits when using an air source heat pump to heat your home with radiant heat instead of a forced air furnace which is exactly why we utilize an air to water system instead of a conventional air to air mini split system like most of our competitors. Trace 700 generates a special report for hvac designs that include water source heat pumps. Implement a water source heat pump system to meet simultaneous heating and cooling demand. The electrical energy saved by the higher cop heat pump over the other heat pump was about 3 7 mmbtu h 1 mmbtu 1 000 000 btu.

Heat pumps work by running a low temperature lower pressure refrigerant fluid in heat exchanger coils through a heat source such as the outside air the ground or circulating water. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas. The design heating load of the house was 18 000 btu hr. Since then subsequent efforts have led to more stringent energy efficiency standards as shown in figure 1.
