Below with reference to accompanying drawing refrigeration system according to the embodiment of the invention is described at first.
As shown in Figure 1, be the schematic diagram of the refrigeration system of one embodiment of the invention.Refrigeration system 100 according to the embodiment of the invention comprises compressor 110, condenser, switch unit 140, refrigerating chamber capillary 150, refrigerator evaporator 160, temperature-changing chamber capillary 170, temperature-changing chamber evaporimeter 180 and freezer evaporator 190.
Wherein, the inlet of condenser links to each other with the outlet of compressor 110, and switch unit 140 has inlet and the first outlet A and the second outlet B.The inlet of switch unit 140 links to each other with the outlet of condenser.The inlet of refrigerator evaporator 160 links to each other with the first outlet A of switch unit 140 by refrigerating chamber capillary 150.The inlet of temperature-changing chamber evaporimeter 180 links to each other with the second outlet B of switch unit 140 by temperature-changing chamber capillary 170.The inlet of freezer evaporator 190 links to each other with the outlet of temperature-changing chamber evaporimeter 180 and the outlet of refrigerator evaporator 160, and the outlet of freezer evaporator 190 links to each other with the inlet of compressor 110.
According to the refrigeration system of the embodiment of the invention, refrigerator evaporator 160 and 180 parallel connections of temperature-changing chamber evaporimeter, and freezer evaporator 190 connects with in parallel refrigerator evaporator 160 and temperature-changing chamber evaporimeter 180, thus refrigeration system has formed two refrigerating circuits.Wherein, first loop is the refrigerating circuit that is formed by compressor 110, condenser, refrigerating chamber capillary 150, refrigerator evaporator 160 and freezer evaporator 190; Second loop is the refrigerating circuit that is formed by compressor 110, condenser, temperature-changing chamber capillary 170, temperature-changing chamber evaporimeter 180 and freezer evaporator 190.
When needs refrigerator evaporator 160 refrigeration, switch unit 140 switches to the first outlet A so that above-mentioned first loop is moved, and refrigerator evaporator 160 freezes.When needs temperature-changing chamber evaporimeter 180 refrigeration, switch unit 140 switches to the second outlet B so that above-mentioned second loop is moved, and temperature-changing chamber evaporimeter 180 freezes.Because freezer evaporator 190 is connected with above-mentioned refrigerator evaporator 160 and temperature-changing chamber evaporimeter 180, so, no matter during in refrigerator evaporator 160 or temperature-changing chamber evaporimeter 180 refrigeration, freezer evaporator 190 is also freezing to refrigerating chamber, therefore, when satisfying the refrigeration requirement, reduced energy consumption.In addition, freezer evaporator 190 is connected with refrigerator evaporator 160 and temperature-changing chamber evaporimeter 180, therefore only use refrigerating chamber capillary 150 and 170 two capillaries of temperature-changing chamber capillary, compare with traditional three capillaries of refrigeration system employing and reduced number of spare parts, reduced cost.
As shown in Figure 1, in preferred embodiments more of the present invention, switch unit 140 for example is a two-position three way magnetic valve.Open first outlet during A when two-position three way magnetic valve, refrigerator evaporator 160 and freezer evaporator 190 freeze, when two-position three way magnetic valve open the second outlet B time, temperature-changing chamber evaporimeter 180 and freezer evaporator 190 freeze.According to the embodiment of the invention, by adopting two-position three way magnetic valve, have the outlet accurate positioning, switch the advantage simple, that controllability is strong.In addition, two-position three way magnetic valve is cheap, long service life.
In some embodiments of the invention, condenser comprises first condenser 120 and second condenser 130.Enter the refrigerant temperature and the pressure height of condenser from compressor 110, first condenser 120 may not be lowered the temperature or cold-producing medium cooling not reached ideal temperature whole cold-producing mediums, therefore, the refrigeration that 130 pairs of residues of second condenser do not reach ideal temperature without lowering the temperature and lowering the temperature is advanced cooling once more, makes the refrigeration of cold-producing medium better.
In preferred embodiments more of the present invention, refrigeration system 100 also comprises dew eliminating tube 200, dew eliminating tube 200 is connected between the condenser 120 and condenser 130 of the foregoing description, temperature when dew eliminating tube 200 is connected on and has guaranteed between condenser 120 and the condenser 130 that condenser is flowed through dew eliminating tube is higher than ambient temperature, prevents to burn owing to refrigerant temperature is too high dew eliminating tube simultaneously.When cold-producing medium is flowed through dew eliminating tube 200, because the temperature of cold-producing medium is higher than ambient temperature, the globule that condenses in around the dew eliminating tube is evaporated, prevent to be arranged on parts around the dew eliminating tube globule that condenses.
In preferred embodiments more of the present invention, refrigeration system 100 also comprises device for drying and filtering 210, and device for drying and filtering 210 is arranged between the condenser 130 and two-position three way magnetic valve of the foregoing description.Cold-producing medium can produce impurity such as moisture, pressed powder, dirt in running, and refrigerating chamber capillary 150 and/or temperature-changing chamber capillary 170 are stopped up.Therefore, impurity such as 210 pairs of moisture of device for drying and filtering, pressed powder, dirt being set before condenser is leading to refrigerating chamber capillary 150 and temperature-changing chamber capillary 170 filters.According to the device for drying and filtering 210 of the embodiment of the invention, prevent that refrigerating chamber capillary 150 and temperature-changing chamber capillary 170 from stopping up, in addition, the moisture of absorption refrigeration agent makes the refrigeration of cold-producing medium better.
In preferred embodiments more of the present invention, refrigeration system also is provided with return-air heat exchanger 220, return-air heat exchanger 220 will turn back to cold-producing medium in the compressor 110 from freezer evaporator 190, and enter into one of them cold-producing mediums of temperature-changing chamber evaporimeter 180 and refrigerator evaporator 160 from two-position three way magnetic valve and will carry out heat exchange.Particularly, refrigeration depends on the temperature of cold-producing medium on the one hand, when temperature reaches a certain scope, refrigerating efficiency is better, so return-air heat exchanger 220 by the embodiment of the invention, by cold-producing medium is carried out heat exchange, can make the temperature of cold-producing medium reach the scope of the temperature of better refrigeration, make refrigeration better.
Refrigeration system according to the embodiment of the invention, can between the temperature-changing chamber evaporimeter of parallel connection and refrigerator evaporator, switch the operation of cold-producing medium by switch unit, and temperature-changing chamber evaporimeter and refrigerator evaporator are connected with freezer evaporator, therefore, by optionally moving temperature-changing chamber evaporimeter and refrigerator evaporator, can be individually to refrigerating chamber and temperature-changing chamber refrigeration, to refrigerating chamber or temperature-changing chamber refrigeration the time, also refrigerating chamber is freezed, reduced energy consumption, and by temperature-changing chamber evaporimeter in parallel and refrigerator evaporator, and they are connected with freezer evaporator, two capillaries have only been used, reduce number of spare parts, reduced cost, and according to the refrigeration system of embodiment of the invention control and simple to operate, secondly, device for drying and filtering by the embodiment of the invention and adopt two or more condensers makes the refrigeration of cold-producing medium better, has prevented the globule that condenses around the dew eliminating tube according to the dew eliminating tube of the embodiment of the invention.
The refrigerator with above-mentioned refrigeration system of the embodiment of the invention is below described.
