Patent attributes
A refrigeration system including a condenser, a compressor, a first transportation system passing refrigerant between the compressor and the condenser, a first evaporator, a second evaporator, a second transportation system passing the refrigerant between the condenser and a holding vessel, with the holding vessel including refrigerant in gas and liquid form, a third transportation system passing the refrigerant between the holding vessel and a pump, a fourth transportation system passing the refrigerant between the pump and the first evaporator, a fifth transportation system passing the refrigerant between the pump and the second evaporator, and a heat exchanger wherein the refrigerant in the second transportation system exchanges heat with the refrigerant in the fifth transportation system to heat the refrigerant in the fifth transportation system before the refrigerant passes to the second evaporator. The refrigerant is expanded between the condenser and the first and second evaporators to lower the pressure thereof.
