Abstract
A warm liquid defrost refrigeration system (,) comprising a primary refrigeration loop (,) including a compressor (,), a condenser (,), an expansion device (,), and a first side of a chiller (,), and a secondary refrigeration loop (,) including a pump (,), a refrigerated space heat exchanger (,), and a second side of the chiller. The refrigeration system further includes a defrost heat exchanger (,) having a hot side and a cold side. The hot side of the defrost heat exchanger is connected to the primary refrigeration loop between the condenser and the expansion device such that liquid refrigerant can flow from the condenser through the hot side of the defrost heat exchanger. The cold side of the defrost heat exchanger is connected to the secondary refrigeration loop at a point downstream of the pump such that coolant can be selectively transported from the pump through the cold side of the defrost heat exchanger. The cold side of said defrost heat exchanger is also connected to the refrigerated space heat exchanger such that it can be selectively used to transport the heated coolant to the refrigerated space heat exchanger for defrost.
