摘要
A CO2 brine production system capable of reliably forming a refrigeration cycle combining an ammonia cycle and a CO2 cycle even when a refrigeration showcase on the cooler side of the CO2 cycle is installed at an arbitrary place for reasons of a client. In the CO2 brine production system comprising an ammonia refrigeration cycle, an evaporator for cooling/liquefying CO2 by utilizing evaporation latent heat of ammonia, and a liquid pump provided on a line for supplying CO2 cooled/liquefied by the evaporator to the cooling load side, the liquid pump is a variable liquid supply forced circulation pump which is subjected to variable control based on at least any one of the temperature and pressure of a CO 2 cooler provided on the cooling load side, and the differential pressure between the inlet and outlet of the pump.
