Abstract
A refrigeration system with heat recovery includes a vapor compression circuit having at least one compressor, a gas cooler, a receiver, a first expansion device fluidly connected between a first refrigerant path of the gas cooler and the receiver, a second expansion device fluidly connected between the receiver and a second refrigerant path of the gas cooler, and at least one evaporator. The refrigeration system includes a heat exchanger configured to exchange heat between refrigerant flowing in the vapor compression circuit and a fluid flowing in a hot fluid circuit. The gas cooler is arranged such that heat from refrigerant flowing in the first refrigerant path of the gas cooler is transferred to refrigerant flowing in the second refrigerant path of the gas cooler when the second expansion device is open and allowing refrigerant flow from the receiver to the second refrigerant path of the gas cooler.
