Particularly, first throttle device 80, second throttling arrangement 90 and the 3rd throttling arrangement 100 are capillary.Because capillary has, cost is low, specification is extensively comprehensive, so by first throttle device 80, second throttling arrangement 90 and the 3rd throttling arrangement 100 are all set to capillary, thus can reduce the manufacturing cost of refrigeration system 1.
More specifically, the first transfer valve 30 and the second transfer valve 40 are all magnetic valves.Because magnetic valve has, cost is low, specification is extensively comprehensive, so by the first transfer valve 30 and the second transfer valve 40 are all set to magnetic valve, thus can reduce the manufacturing cost of refrigeration system 1.
Refrigerator according to the embodiment of the present invention is described below.This refrigerator comprises casing, Men Ti, refrigeration system 1 and controller.
There is in casing refrigerating chamber, refrigerating chamber and temperature-changing chamber.Door body is arranged on casing, for opening and closing refrigerating chamber, refrigerating chamber and temperature-changing chamber.Wherein refrigerating evaporator 50 is for freezing to the refrigerating chamber of refrigerator, and refrigeration evaporator 60 is for the refrigeration chamber to refrigerator, and alternating temperature evaporimeter 70 is for freezing to the temperature-changing chamber of refrigerator.Controller is connected with the second transfer valve 40 with compressor 10, first transfer valve 30 respectively, with the temperature of the refrigerating chamber according to refrigerator, refrigerating chamber and temperature-changing chamber, controls the operation of compressor 10 and the first transfer valve 30 and the second transfer valve 40.
According to the refrigerator of the embodiment of the present invention, by the switching of the first and second transfer valves of refrigeration system 1, can switch refrigerant circulation, multiple refrigerant circulating path can be realized, reach the different refrigeration of the refrigerating chamber of refrigerator, refrigerating chamber and temperature-changing chamber.
Specifically, user as required, can utilize the operation of controller to the first transfer valve 30 and the second transfer valve 40 to control, reaches the different refrigeration of refrigerating chamber, refrigerating chamber and temperature-changing chamber, the use of refrigerator can be made thus convenient.
Certainly, it should be noted that here, controller can pass through preset control program, to control the operation of the first transfer valve 30 and the second transfer valve 40 for the difference input of user, can make the more convenient to operate of refrigerator thus.
In addition, the control inputs for the first transfer valve 30 and the second transfer valve 40 can be not only the demand input of user, also can be the temperature input of the refrigerating chamber of refrigerator, refrigerating chamber and temperature-changing chamber.Thus, refrigerator automatically can control the operation of the first transfer valve 30 and the second transfer valve 40, be switched to more rationally according to the temperature of refrigerating chamber, refrigerating chamber and temperature-changing chamber, more energy-conservation refrigerant circulation mode.
Correspondingly, in a specific embodiment of the present invention, refrigerator also comprises temperature detector, this temperature detector is for detecting the temperature in refrigerating chamber, refrigerating chamber and temperature-changing chamber, and surveyed temperature value is transferred in controller, so that controller calculates optimum refrigerant circulation mode according to institute's side temperature value, and controls the operation of the first transfer valve 30 and the second transfer valve 40.Refrigerator can be made thus more intelligent, use convenient, more energy-conservation.
Advantageously, refrigerator also can comprise temperature indicating device, and temperature indicating device is connected with temperature detector to show the temperature in refrigerating chamber, refrigerating chamber and temperature-changing chamber.By set temperature display unit and temperature detector, thus user can be made to see the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber detected by temperature detector by temperature indicating device, thus, user can be enable to understand temperature range in the refrigerating chamber of refrigerator, refrigerating chamber and temperature-changing chamber more intuitively.Also be conducive to user monitor the temperature in the refrigerating chamber of refrigerator, refrigerating chamber and temperature-changing chamber and control simultaneously.Therefore, the use of refrigerator can be made convenient.
