Further, refrigeration system 1 also comprises anti-condensation pipe 110, and anti-condensation pipe 110 is connected between the first condenser 21 and the second condenser 22.Particularly, anti-condensation pipe 110 can be arranged on refrigerator Men Tiyu casing contact around.By between the first condenser 21 and the second condenser 22, anti-condensation pipe 110 being set, thereby can prevent because door body condensation when air humidity is large of refrigerator.
Preferably, refrigeration system 1 also comprises device for drying and filtering 120, and device for drying and filtering 120 is connected between the import 31 of the outlet of condenser 20 and the first transfer valve 30.By before the import 31 of the first transfer valve 30, device for drying and filtering 120 being set, not only can remove the residual moisture in the refrigeration system 1, thereby anti-stagnant ice is stifled, and can reduce moisture to the corrosiveness of refrigeration system 1, and the impurity in can filtering refrigeration system 1, such as metal fillings, various oxide and dust etc., thus can avoid first throttle device 80, the second throttling arrangement 90 and the 3rd throttling arrangement 100 dirty stifled.
Particularly, first throttle device 80, the second throttling arrangement 90 and the 3rd throttling arrangement 100 are capillary.Because capillary has that cost is low, specification extensively and comprehensively, so by first throttle device 80, the second throttling arrangement 90 and the 3rd throttling arrangement 100 all being made as capillary, thereby can reduce the manufacturing cost of refrigeration system 1.
More specifically, the first transfer valve 30 and the second transfer valve 40 all are magnetic valves.Because magnetic valve has that cost is low, specification extensively and comprehensively, so by the first transfer valve 30 and the second transfer valve 40 all are made as magnetic valve, thereby can reduce the manufacturing cost of refrigeration system 1.
Refrigerator according to the embodiment of the invention is described below.This refrigerator comprises casing, door body, refrigeration system 1 and controller.
Have refrigerating chamber, refrigerating chamber and temperature-changing chamber in the casing.The door body is installed on the casing, is used for opening and closing refrigerating chamber, refrigerating chamber and temperature-changing chamber.Wherein refrigerating evaporator 50 is used for the refrigerating chamber refrigeration to refrigerator, and refrigeration evaporator 60 is used for the refrigerating chamber refrigeration to refrigerator, and alternating temperature evaporimeter 70 is used for the temperature-changing chamber refrigeration to refrigerator.Controller links to each other with compressor 10, the first transfer valve 30 and the second transfer valve 40 respectively, with the temperature according to refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator, and the operation of control compressor 10 and the first transfer valve 30 and the second transfer valve 40.
Refrigerator according to the embodiment of the invention, the switching of the first and second transfer valves by refrigeration system 1, can switch refrigerant circulation, can realize multiple refrigerant circulation path, reach the different refrigeration of refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.
Particularly, the user can utilize controller to come the operation of the first transfer valve 30 and the second transfer valve 40 is controlled as required, reaches the different refrigeration of refrigerating chamber, refrigerating chamber and temperature-changing chamber, can make thus the use of refrigerator convenient.
Certainly, need to prove here, controller can by presetting control program, in order to come the operation of the first transfer valve 30 and the second transfer valve 40 is controlled for user's difference input, can make the more convenient to operate of refrigerator thus.
In addition, not only can be user's demand input for the control inputs of the first transfer valve 30 and the second transfer valve 40, also can be the temperature input of refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.Thus, refrigerator can automatically be controlled the operation of the first transfer valve 30 and the second transfer valve 40 according to the temperature of refrigerating chamber, refrigerating chamber and temperature-changing chamber, switches to more rationally, 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 detection of the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber, and the temperature value of surveying is transferred in the controller, so that controller calculates optimum refrigerant circulation mode according to institute's side temperature value, and control the operation of the first transfer valve 30 and the second transfer valve 40.Can make thus refrigerator more intelligent, use convenient, more energy-conservation.
Advantageously, refrigerator also can comprise temperature indicating device, and temperature indicating device links to each other to show the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber with Temperature Detector.By set temperature display unit and Temperature Detector, thereby can make the user see temperature in the detected refrigerating chamber of Temperature Detector, refrigerating chamber and the temperature-changing chamber by temperature indicating device, thus, can make the user can understand more intuitively the interior temperature range of refrigerating chamber, refrigerating chamber and temperature-changing chamber of refrigerator.Simultaneously also being conducive to the user monitors and controls the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.Therefore, can make the use of refrigerator convenient.
