A heat pump can switch from air condition mode to heat mode by reversing the refrigeration cycle making the outside coil function as the evaporator and the indoor coil as the condenser.
Heat pump refrigerant flow diagram.
Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold area and releasing it to a warmer one.
The hfc refrigerant emissions from heat pumps over the lifetime are roughly 2 to 5 mg mj.
Air is blown over an evaporator coil transferring heat energy from the air to the refrigerant.
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.
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.
The refrigerant flows through a closed system of refrigeration lines between the outdoor and the indoor unit.
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 versatile efficient cooling and heating system.
Thanks to a reversing valve a heat pump can change the flow of refrigerant and either heat or cool a home.
