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.
