Below with reference to the refrigeration system 10 of Fig. 1 description according to the embodiment of the present invention.As shown in Figure 1, the refrigeration system 10 according to the embodiment of the present invention comprises compressor 100, condenser, the first flow direction controller 310, the first capillary 410, the second capillary 420, refrigerating evaporator 500 and refrigeration evaporator 600.
The entrance of described condenser is connected with the outlet of compressor 100, and the entrance of the first flow direction controller 310 is connected with the outlet of described condenser.The entrance of the first capillary 410 is connected with the first outlet of the first flow direction controller 310, and the entrance of the second capillary 420 is connected with the second outlet of the first flow direction controller 310.The entrance of refrigerating evaporator 500 is connected with the outlet of the first capillary 410 and the outlet of the second capillary 420 respectively.The entrance of refrigeration evaporator 600 is connected with the outlet of refrigerating evaporator 500 by the first muffler 710 and the outlet of refrigeration evaporator 600 is passed through the second muffler 720 and is connected with the entrance of compressor 100, and wherein the first muffler 710 has for the first return-air heat exchanging segment 711 that carries out heat exchange with the second capillary 420.
With reference to the course of work of Fig. 1 description according to the refrigeration system 10 of the embodiment of the present invention.When the user normally uses, cold-producing medium is from compressor 100 flow through successively described condenser and the first flow direction controller 310, and flow into the first capillary 410 under the control of the first flow direction controller 310, flow through successively refrigerating evaporator 500, the first muffler 710, refrigeration evaporator 600 and the second muffler 720 of cold-producing medium subsequently, last cold-producing medium flows back to compressor 100.
When the user selects the quick-frozen function (when the user needs refrigeration system 10 that large refrigerating capacity is provided, for example when the user with more article or large article put into refrigerator refrigerating chamber and need to described article are rapid when freezing), cold-producing medium is from compressor 100 flow through successively described condenser and the first flow direction controller 310, and flow into the second capillary 420 under the control of the first flow direction controller 310, flow through successively refrigerating evaporator 500, the first muffler 710, refrigeration evaporator 600 and the second muffler 720 of cold-producing medium subsequently, last cold-producing medium flows back to compressor 100.The cold-producing medium that wherein flows out from refrigerating evaporator 500 carries out heat exchange with the cold-producing medium the second capillary 420 in when flowing through the first return-air heat exchanging segment 711 of the first muffler 710, namely the interior cold-producing medium of the interior cold-producing medium of the first return-air heat exchanging segment 711 of the first muffler 710 and the second capillary 420 carries out heat exchange.The temperature of the cold-producing medium in the first return-air heat exchanging segment 711 can be improved widely like this, in other words, the temperature of the cold-producing medium that flows into refrigeration evaporator 600 can be improved widely.Because the cold-producing medium that flows into refrigeration evaporator 600 has higher temperature, therefore can improve the evaporating temperature of refrigeration evaporator 600, even like this in the long playing situation of compressor 100, the temperature constant of refrigerating chamber is spent at 2 degree-8.Because refrigeration system 10 can make compressor 100 long-plays in the situation that do not reduce the temperature of refrigerating chamber, so the refrigerating capacity of refrigeration system 10 can be increased to 16kg/100L, and namely refrigeration system 10 has the quick-frozen ability.
Can cause when the compressor long-play temperature of refrigerating chamber to drop to below 0 degree due to existing refrigeration system, thereby cause the interior vegetables of refrigerating chamber, fruit etc. to freeze, therefore the compressor of existing refrigeration system can not long-play, the refrigerating capacity of existing like this refrigeration system is only 4.5kg/100L, does not have the quick-frozen ability.
According to the refrigeration system 10 of the embodiment of the present invention by the first capillary 410 being set and being connected capillary 420 and connect the outlet of refrigerating evaporator 500 and the first muffler 710 of the entrance of refrigeration evaporator 600 is provided with the first return-air heat exchanging segment 711, thereby can make refrigeration system 10 have normal and two kinds of refrigeration modes of snap frozen.When refrigeration system 10 is in the snap frozen refrigeration mode, cold-producing medium flows into the second capillary 420 under the control of the first flow direction controller 310, and carry out heat exchange with the cold-producing medium in the second capillary 420 from the cold-producing medium that refrigerating evaporator 500 flows out when flowing through the first return-air heat exchanging segment 711 of the first muffler 710, can improve widely like this temperature of the interior cold-producing medium of the first return-air heat exchanging segment 711.Because the cold-producing medium that flows into refrigeration evaporator 600 has higher temperature, therefore can improve the evaporating temperature of refrigeration evaporator 600, even like this in the long playing situation of compressor 100, the temperature constant of refrigerating chamber is spent at 2 degree-8.Because refrigeration system 10 can make compressor 100 long-plays in the situation that do not reduce the temperature of refrigerating chamber, so the refrigerating capacity of refrigeration system 10 can be increased to 16kg/100L, and namely refrigeration system 10 has the quick-frozen ability.In other words, although refrigeration system 10 can improve the evaporating temperature of refrigeration evaporator 600, because compressor 100 can long-play, therefore also can make the temperature of refrigerating chamber reach predetermined temperature (2 degree-8 degree).
