This system effectively can improve the coefficient of heat transfer of evaporimeter, effectively reduces compressor wasted work, thus significantly improve cooling system coefficient under the prerequisite that refrigerating capacity is constant
Its structure is:
The input going out heat-exchange tube in termination steam generator 2 of compressor 1, the input of the output termination condenser 3 of heat-exchange tube in this steam generator 2, the output of condenser 3 divides two-way, the first via connects the input of gas-liquid separator 5 by choke valve 4, and the second tunnel connects the input of steam generator 2 by liquid booster pump 8; What the fluid output port of gas-liquid separator 5 connect compressor 1 by evaporimeter 6 enters end; The gas output end of gas-liquid separator 5 divides two-way, and the first via connects the first input end of injector 7 by the first magnetic valve 10, the second tunnel by the second magnetic valve 11 connect compressor 1 enter end; The gas output end of steam generator 2 connects the second input of injector 7, the input of the output condenser 3 of injector 7 by the 3rd magnetic valve 12.
Its method is:
Two-way is divided by the saturated liquid cold-producing medium after condenser cooling condensation, one tunnel is through choke valve throttling decrease temperature and pressure, another road enters in generator through liquid booster pump supercharging, and fluid level controller, according to the start and stop of generator Liquid level booster pump, reaches the object of control generator liquid level.
At system start-up phase, the regular hour is needed by the saturated gas that exhaust outlet of compressor superheated steam out (state point b) heat air changes under generation pressure, so temporarily first close the 3rd magnetic valve owing to being pressurized to by liquid booster pump the saturated liquid cold-producing medium (state point h) occurred under pressure in generator.Now injector cannot work because not having working steam, so the first magnetic valve will be closed, open the second magnetic valve, flash gas after gas-liquid separator separates (state point g) is directly sucked by compressor and without evaporimeter, avoid flashed vapour and enter the heat exchange area that evaporimeter makes evaporimeter limited and can not be utilized very well and reduce the coefficient of heat transfer.
