Abstract
A heating system including a condenser and an evaporator. A compressor is along a refrigerant line and is configured to compress refrigerant flowing to the condenser. A first valve is along the refrigerant line between the compressor and the condenser. A controller is configured to partially close the first valve when a measured temperature is below a threshold to increase discharge pressure of refrigerant compressed by the compressor and increase heat dissipation of the condenser.
