Heat Pump Refrigerant Flow Diagram

In two phase flow systems a heat pump is a device that transfers energy from a heat source to a destination called a heat sink.

Heat pump refrigerant flow diagram.

Air is blown over an evaporator coil transferring heat energy from the air to the refrigerant. You can also view the 2 modes showing the refrigerant states with buttons 4 and 5. The hfc refrigerant emissions from heat pumps over the lifetime are roughly 2 to 5 mg mj. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump air conditioning and refrigeration systems.

A heat pump is a mechanical system that allows for the transmission of heat from one location the source at a lower temperature to another location the sink or heat sink at a higher temperature. 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. For a heat pump with refrigerant r134a hfc 134a which has a 100 years global warming potential of 1300 this corresponds to ghg emissions of about 3 6 g mj co 2 equiv. A heat pump is a versatile efficient cooling and heating system.

The refrigerant flows through a closed system of refrigeration lines between the outdoor and the indoor unit. Thanks to a reversing valve a heat pump can change the flow of refrigerant and either heat or cool a home.
