Abstract
A method for switching the flow path of refrigerant with decoupled compressors is disclosed. The method comprises receiving a detected ambient temperature from a temperature sensor circuit. The method further comprises determining whether the detected ambient temperature is less than a threshold ambient temperature. The method further comprises communicating a first electronic signal to a switching valve to direct a flow path of the refrigerant from the switching valve toward an outdoor heat exchanger in response to determining that the detected ambient temperature is less than the threshold ambient temperature. The method further comprises communicating a second electronic signal to the switching valve to direct the flow path of the refrigerant from the switching valve toward a flash tank in response to determining that the detected ambient temperature is more than or equal to the threshold ambient temperature.
