Describe refrigeration system according to the embodiment of the invention in detail below with reference to accompanying drawing.
As shown in Figures 1 to 4, the refrigeration system according to the embodiment of the invention comprises: the first refrigeration branch road 10, the second refrigeration branch roads 20, heat exchanger 30 switch units.
Need to prove at this, refrigeration system according to the embodiment of the invention mainly is applicable to the refrigeration plants such as refrigerator, be used for being freezed in chamber between the refrigeration of refrigerator, for example, the first refrigeration branch road 10 is used for that refrigerating chamber to refrigerator freezes and the second refrigeration branch road 20 is used for the refrigerating chamber of refrigerator is freezed.Certainly, also not only being confined to refrigerator, can also be other refrigeration plants, as long as have two refrigeration spaces independent of each other.
Specifically, the first refrigeration branch road 10 comprises the first compressor 11, the first condenser 12 and first evaporimeter 13 of series connection.
The second refrigeration branch road 20 comprises the second compressor 21, the second condenser 22 and second evaporimeter 23 of series connection.
Described switch unit is connected in the second refrigeration branch road 20, be used for optionally making the first refrigeration branch road 10 and the second refrigeration branch road 20 mutual independent operatings, heat exchanger 30 and the first evaporimeter 13 are freezed jointly, perhaps make the cold-producing medium in the second refrigeration branch road 20 heat the first evaporimeter 13 by heat exchanger 30 in order to pass through heat exchanger 30.
In other words, according to an example of the present invention, as shown in Figure 1, described switch unit comprises the first transfer valve 40 and the second transfer valve 50.The first transfer valve 40 has first interface 41, the second interface 42 and the 3rd interface 43.The second transfer valve 50 has the 4th interface 51, the 5th interface 52 and the 6th interface 53.
The first interface 41 of the first transfer valve 40 links to each other with the outlet of the second compressor 21 and the second interface 42 of the first transfer valve 40 links to each other with the import of the second condenser 22.
The 4th interface 52 of the second transfer valve 50 links to each other with the outlet of the second condenser 22 and the 5th interface 52 of the second transfer valve 50 links to each other with the import of the second evaporimeter 23.
The import of heat exchanger 30 links to each other with the 6th interface 53 of the 3rd interface 43 of the first transfer valve 40 and the second transfer valve 50 respectively and the outlet of heat exchanger 30 links to each other with the import of the second evaporimeter 23.
Need to prove that at this arrow among Fig. 1 to Fig. 4 has been indicated the trend of cold-producing medium, therefore, above-mentioned " outlet " and " import " are understandable for the person of ordinary skill of the art, do not repeat them here.
As shown in Figure 2, according to an example of the present invention, the second interface 42 of the first transfer valve 40 disconnects and the 6th interface 53 of the second transfer valve 50 disconnects so that the first refrigeration branch road 10 and the second refrigeration branch road 30 mutual independent operatings.That is to say, in this case, heater 30 is not worked, by the first compressor 11, the first condenser 12 and the first evaporimeter 13 be in series first the refrigeration branch road 10, and by the second compressor 21, the second condenser 22 and the second evaporimeter 23 be in series second the refrigeration branch road 20 do not interfere with each other, independent operating.
As shown in Figure 3, according to an example of the present invention, the second interface 42 of the first transfer valve 40 disconnects and the 5th interface 52 of the second transfer valve 50 disconnects so that heat exchanger 30 and the first evaporimeter 13 freeze jointly.That is to say, when freezing requirement the such as speed is cold, deep cooling need to be arranged when chamber between the first refrigeration branch road 10 corresponding refrigeration, heat exchanger 30 can be used as an extra evaporimeter and the first evaporimeter 13 freezes jointly, to strengthen refrigerating capacity, takes full advantage of the refrigerating capacity of double-compressor refrigeration system.
As shown in Figure 4, according to an example of the present invention, when the first refrigeration system 10 is out of service, the second interface 42 of the first transfer valve 40 disconnects and the 6th interface 53 of the second transfer valve 50 disconnects so that the cold-producing medium in the second refrigeration branch road 20 by heat exchanger 30 so that by heat exchanger 30 heating the first evaporimeter 13.That is to say that at this moment, heat exchanger 30 has the effect of defrosting heater and condenser simultaneously, utilize the refrigerant heat by heat exchanger to heat defrosts to the first evaporimeter 13.
That is to say, heat exchanger 30 can be by the switching between the interface of the first transfer valve 40 and the second transfer valve 50, heat exchanger 30 is disconnected with the second refrigeration branch road 20 or heat exchanger 30 freeze jointly as evaporimeter and the first evaporimeter 13 or make cold-producing medium optionally pass through heat exchanger 30, so that heat exchanger 30 as the outside transferring heat energy of condenser, is processed the first evaporimeter 13 is carried out defrost.
According to an example of the present invention, the first transfer valve 40 and the second transfer valve 50 can be magnetic valve.
Refrigeration system according to the embodiment of the invention, control by switch unit, can optionally make the first and second refrigeration system isolated operations or make heat exchanger and the common refrigeration of the first evaporimeter is carried out defrost reducing energy consumption to strengthen refrigerating capacity or heat exchanger heats the first evaporimeter, simple in structure, refrigerating capacity is strong, energy consumption is low.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although the above has illustrated and has described embodiments of the invention, be understandable that, above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, those of ordinary skill in the art can change above-described embodiment in the situation that does not break away from principle of the present invention and aim within the scope of the invention, modification, replacement and modification.
