Description
Affiliated technical field
The utility model relates to the heat-exchange system of a kind of refrigerator, refrigerator-disinfection cabinet all-in-one machine, particularly a kind of heat-exchange system that is used for multi-refrigerating circuit refrigerator and refrigerator-disinfection cabinet all-in-one machine.
Background technology
Along with the depletion and the environmental pollution of resource are serious day by day, countries in the world are all towards the target of setting up a conservation-minded society and effort, the vital task that energy-saving and emission-reduction are pendulum in face of we everyone.
Refrigerator can be realized the characteristics of the preservation by low temperature of object because of it, has entered huge numbers of families, numerous market and numerous laboratory, for the human lives brings great convenience.Because refrigerator is in running order for a long time, so refrigerator has become the household electrical appliance of power consumption in the family.Calculate by every refrigerator power consumption every day 0.70 degree, there are 1,000,000,000 refrigerators in the whole world, annual power consumption 2,550 hundred million degree in the whole world, and every degree power consumption coal 360 grams, 9,198 ten thousand tons in conversion consumption coal is equivalent to 15,636 ten thousand tons of earth row carbon dioxide.
Along with the raising of people's living standard, people are more and more high to the hygienic requirements degree of tableware, and it is more and more fast that disinfection cabinet enters the speed of family, to the whole world in 2008 2.4 hundred million disinfection cabinets arranged.But popular in the market disinfection cabinet need consume a large amount of electric energy, calculates by every disinfection cabinet power consumption every day 0.54 degree, global annual disinfection cabinet power consumption 39,400,000,000 degree, and 1,420 ten thousand tons in conversion consumption coal is equivalent to 2,410 ten thousand tons of earth discharging carbon dioxide.Because freezer compressor often needs refrigeration, in refrigeration time, is with heat extraction, disinfection cabinet can utilize the useless heat of these discharges to keep high temperature drying (after the drying, bacterium dries out and can't survive), and be used ozone generator or ultraviolet germicidal lamp when being necessary, can realize the germ-free condition of tableware.
Comprise two refrigerating circuits, three refrigerating circuits and more the refrigerator of multi-refrigerating circuit all be freezer evaporator to be arranged on the downstream of refrigerating circuit, and refrigerator evaporator is arranged on the upstream of refrigerating circuit.Fig. 1 and Fig. 2 have showed the schematic diagram of two refrigerating circuit refrigerators and three refrigerating circuit refrigerators respectively.From Fig. 1 and Fig. 2 as can be seen: be introduced into refrigerator evaporator 9 through the cold-producing medium after 6 throttlings of first capillary, and then enter freezer evaporator 11 through refrigeration-freezing tube connector 12; Enter freezer evaporator 11 equally through the elder generation of the cold-producing medium after 7 throttlings of second capillary process temperature-changing chamber evaporimeter 10, and then through alternating temperature-freezing tube connector 13.More than the common trait in two loops be that cold-producing medium all will enter refrigerating chamber at last, because freezer temperature is low, the refrigerant temperature that flows out from the port of export of freezer evaporator 11 will be very low, and this can cause the temperature of the cold-producing medium in the muffler 14 low, exist to show the cold inadequate problem of utilizing.
Comprise in addition two refrigerating circuits, three refrigerating circuits and more the refrigerator of multi-refrigerating circuit all have the difference variation of refrigerating chamber inner bag rear wall (the process of refrigerastion temperature be low to-35 ℃ up to 40 ℃; shut down the back temperature and can return to 5 ℃); not only can make the nutrient loss of food; and often causing fruit or vegetables in the refrigerating chamber to be damaged by frost, this is the problem that the client often complains.
Comprise in addition two refrigerating circuits, three refrigerating circuits and more the refrigerator of multi-refrigerating circuit all have the problem that refrigerating chamber can't independent cooling, have only the refrigerating chamber could independent cooling.When the client only needs the refrigerating chamber refrigeration, have to refrigerating chamber is also freezed.
Summary of the invention
Show the cold problem insufficient, that refrigerating chamber inner bag rear wall difference variation big and refrigerating chamber can not independent cooling of utilizing in order to solve, adopt reverse thinking refrigerator evaporator to be arranged on the downstream of refrigerating circuit, the port of export of freezer evaporator is connected to the arrival end of refrigerator evaporator, refrigerator evaporator is placed in the anti-icing fluid box.Because refrigerator evaporator is placed in the anti-icing fluid, because the anti-icing fluid temperature is lower than the surface temperature of refrigerator evaporator, and can be all the time to refrigerating chamber inner bag cooling, so refrigerating chamber inner bag rear wall difference variation will be dwindled greatly; Because the anti-icing fluid temperature is lower than the temperature of refrigerating chamber, so it is more abundant to show cold utilization; Because the liquid NATURAL CONVECTION COEFFICIENT OF HEAT of anti-icing fluid is far longer than the natural convection air coefficient of heat transfer, so refrigerating chamber can separate refrigeration.
The utility model is used for the heat-exchange system of multi-refrigerating circuit refrigerator and refrigerator-disinfection cabinet all-in-one machine, it comprises compressor 1, compressor exhaust pipe 2, condenser 3, device for drying and filtering 4, the multidigit various way solenoid valve, some capillaries, refrigerator evaporator 9, freezer evaporator 11, compressor return air pipe 14, be characterised in that described freezer evaporator 11 links to each other with the multidigit various way solenoid valve by different capillaries respectively with refrigerator evaporator 9 arrival ends, the port of export of described freezer evaporator 11 is connected to the arrival end of refrigerator evaporator 9 by frozen-refrigerated tube connector 16, and the port of export of refrigerator evaporator 9 links to each other with compressor return air pipe 14.
Described refrigerator evaporator 9 is placed in the anti-icing fluid box 15; Described freezing-return-air tube connector 19 couples together the port of export and the described compressor return air pipe 14 of freezer evaporator 11; Described normally closed two-port valve 18 be installed in described freezing-return-air tube connector 19 on; Be equipped with on the described frozen-refrigerated tube connector 16 and often drive two-port valve 17.
The utility model is disclosed, and to be used for the effect of heat-exchange system of multi-refrigerating circuit refrigerator and refrigerator-disinfection cabinet all-in-one machine as follows:
1. because the temperature of anti-icing fluid is starkly lower than the tube wall temperature of refrigerator evaporator 9, so the difference variation of refrigerating chamber inner bag rear wall can reduce greatly.
2. be immersed in the anti-icing fluid owing to refrigerator evaporator 9, so the situation of frosting can not appear in refrigerator evaporator 9, so do not need frequent defrost.
3. temperature of refrigerating chamber is more even, and it is fresh-keeping to help fruit and vegetable.
4. be immersed in the anti-icing fluid owing to refrigerator evaporator 9, because of the liquid NATURAL CONVECTION COEFFICIENT OF HEAT is far longer than the natural convection air coefficient of heat transfer, not only the refrigerating chamber separate refrigeration can be realized, and the apparent cold utilization rate of first refrigerating circuit, second refrigerating circuit can be improved.
5. owing to improved the coefficient of heat transfer of refrigerator evaporator 9, so can select the capillary (being that capillary pipe length is shorter or capillary inner diameter is bigger) of bigger flow for use, can improve the Energy Efficiency Ratio of compressor like this, also provide possibility for same evaporimeter adopts double capillary.
