Heat Pump Flow Diagram

Ac heat pump with standard air handler and single stage electric backup heat standard heat pump thermostat heat pump condenser 24 volt fan only operation common air conditioning heat pump reversing valve electric backup heat low voltage connection some ac systems will have a blue wire with a pink stripe in place of the yellow or y wire.

Heat pump flow diagram. Heat pump flow controller field supplied full port ball valve each heat pump must include p t ports to verify flow rates lwt ewt heat pump flow center ewt lwt lwt ewt to ground loop heat pump heat pump field supplied full port ball valve for balancing field supplied check valve to prevent short cycling. The part of the heat pump system that reverses the flow of refrigerant allowing the system to operate in the opposite direction and switch between heating and cooling. Click back and forth between buttons 2 and 3 and note how the discharge from the compressor is diverted to different coils in each mode. A wshp contains all the components of a refrigeration circuit including one or.

As they say a picture worth a thousand words. You can also view the 2 modes showing the refrigerant states with buttons 4 and 5. Heat pump energy flow. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump air conditioning and refrigeration systems.

Process flow diagrams are widely used by engineers in chemical and process engineering they allows to indicate the general flow of plant process streams and equipment helps to design the petroleum refineries petrochemical and chemical plants natural gas processing plants and. A process flow diagram pfd is a diagram which shows the relationships between the main components in a system. As the name suggests a heat pump transfers or pumps heat from one place to another notice the use of the word pump heat is not generated but rather is moved. The heat pump is very simple once you understand the basic concept and i promise you will after reading this.

The expansion valve acts as a metering device regulating the flow of the refrigerant as it passes through the system allowing for a reduction of pressure and. The electric heat pump can overcome the thermal bottleneck imposed by the second law of thermodynamics for the purpose of heating a house. As the illustration shows an electric heat pump can deliver more heat to a house than burning the primary fuel at 100 efficiency inside the house.
