Abstract: A pumped refrigerant system can include a condenser, a pump coupled downstream of the condenser, an evaporator assembly coupled downstream of the pump, the condenser being coupled downstream of the evaporator assembly, and a refrigerant heating assembly coupled downstream of the pump, the condenser being coupled downstream of the refrigerant heating assembly. The refrigerant heating assembly can include a tank and a heating element coupled to the tank and configured to heat refrigerant within the tank. An input valve can be configured to selectively allow the pump to push refrigerant into the tank. An output valve can be configured to selectively inject heated refrigerant from the tank into plumbing upstream of the condenser.

Abstract: A system for detecting and mitigating a refrigerant leak includes a temperature control device configured to transmit control signals to a component controller and a blower configured to circulate air. The system includes a leak mitigation controller electrically coupled to the temperature control device and the component controller. The leak mitigation controller directs incoming power to the temperature control device. The leak mitigation controller includes a sensor configured to measure a refrigerant concentration and a relay configured to selectively: (i) connect the temperature control device to the incoming power or (ii) connect the blower to the incoming power. The leak mitigation controller is configured to measure the refrigerant concentration with the sensor and, in response to the measured refrigerant concentration exceeding a threshold, actuate the relay to connect the blower to the incoming power.
