The refrigerant steam compressed system which has 2 systematic economizer circuits

摘要

The refrigerant steam compressed system with the heat exchanger for refrigerant heat dissipation of refrigerant circuit and the heat exchanger refrigerant endothermic, has with the flash tank economizer and the refrigerant anti- refrigerant heat exchanger economizer which are arranged in serial relationship as a flow of the refrigerant. In order the primary expansion valve on high-level side of the heat exchanger refrigerant endothermic of the refrigerant circuit in order to operate in connection with the heat exchanger said refrigerant endothermic, as it is arranged, the economizer expansion valve to operate on flash tank economizer high-level side of the refrigerant circuit pertaining to the said flash tank economizer, we are arranged, from the heat exchanger for refrigerant heat dissipation expansion of the refrigerant which passes by the refrigerant circuit, becomes 2 step type expansion processes to the heat exchanger refrigerant endothermic depending upon these expansion valves.
