Abstract
A method and system for preventing temperature undershoot in a refrigerant loop during extreme temperatures includes determining a sensed condition at a refrigerant loop and when the sensed condition is below a first threshold starting a flow of coolant in a coolant loop comprising a first portion of a first heat exchanger. The method further includes raising the temperature of the coolant from a heat source to form heated coolant, communicating refrigerant through a second portion of the first heat exchanger, heating the refrigerant in the refrigerant loop at the first heat exchanger from the heated coolant and starting a flow of refrigerant in the refrigerant loop by starting a compressor within the refrigerant loop.
