Below with reference to accompanying drawing 1-3 refrigerator according to the embodiment of the invention is described.
Refrigerator according to the embodiment of the invention comprises casing (not shown) and refrigeration system.Be limited with chamber between refrigeration in the casing.Refrigeration system is used for being freezed in chamber between refrigeration.
Particularly, refrigeration system comprises compressor 1, condenser 2, capillary 3, pipe evaporator 4 and temperature controller (not shown).
The entrance 21 of condenser 2 links to each other with the outlet 12 of compressor 1, and capillary 3 links to each other with the outlet 22 of condenser, and the entrance of evaporimeter 4 links to each other with capillary 3, and the outlet of evaporimeter 4 links to each other with the entrance 11 of compressor 1, to form kind of refrigeration cycle.
Temperature controller is for detection of an indoor temperature and according to the startup of this temperature control compressor 1 with stop, and has the function of refrigeration design temperature and freezing design temperature, namely can switch between refrigeration design temperature and freezing design temperature.
Switch to the refrigeration design temperature at temperature controller, the chamber can be used as the refrigerating chamber use between freezing this moment.When indoor temperature between refrigeration was higher than the refrigeration design temperature, temperature controller control compressor 1 started, and temperature controller control compressor 1 is out of service when indoor temperature between refrigeration reaches the refrigeration design temperature.
And switching to freezing design temperature at temperature controller, the chamber can be used as the refrigerating chamber use between freezing this moment.When indoor temperature was higher than freezing design temperature between refrigeration, temperature controller control compressor 1 started, and temperature controller control compressor 1 is out of service when indoor temperature reaches freezing design temperature between refrigeration.
Thus, can freely switch chamber between refrigeration between refrigerating chamber and the refrigerating chamber as required according to the refrigerator of the embodiment of the invention, and refrigerator structure of the present invention simple, be convenient to make.
According to one embodiment of present invention, the chamber comprises refrigerating chamber and refrigerating chamber between refrigeration.The refrigerating evaporator 42 that evaporimeter 4 comprises for the refrigeration evaporator 41 that refrigerating chamber is freezed and is used for refrigerating chamber is freezed.For detection of the cryogenic temperature of refrigerating chamber and have refrigeration design temperature and freezing design temperature (being the switchable type temperature controller), and do not establish the temperature controller for detection of freezing indoor temperature at temperature controller.
As shown in Figure 1, capillary 3, refrigerating evaporator 42 and refrigeration evaporator 41 are connected between the outlet 22 of the entrance 11 of compressor 1 and condenser 2 successively, thus, cold-producing medium flows out from the outlet 12 of compressor 1 and enters refrigerating evaporator 42 and refrigeration evaporator 41 successively by condenser 2 and capillary 3, flows back to the entrance 11 of compressor 1 again.
Preferably, the refrigerating capacity of refrigerating evaporator 42 is greater than the refrigerating capacity of refrigeration evaporator 41, those of ordinary skills can realize by means known, for example make it greater than the size of refrigeration evaporator 41 and improve the heat exchange environment etc. of refrigerating chamber by the size that increases refrigerating evaporator 42.In addition, because the structure of above-mentioned refrigeration system, after evaporimeter 1 started, refrigerating evaporator 42 at first began refrigeration, next be that the refrigeration evaporator of contacting with it begins refrigeration, so the refrigeration of refrigerating evaporator 42 is better than the refrigeration of refrigeration evaporator 41.
When temperature controller switched to freezing design temperature, this moment, refrigerating chamber used as refrigerating chamber, and temperature controller detects the temperature in the refrigerating chamber.If temperature controller control compressor was out of service when the temperature in the refrigerating chamber reached freezing design temperature, this moment, the temperature in the refrigerating chamber also reached freezing design temperature because the refrigeration of refrigerating evaporator 42 is better than the refrigeration of refrigeration evaporator 41.Otherwise, if refrigerating chamber temperature controller then control compressor start when the temperature in the refrigerating chamber is higher than freezing design temperature.
When temperature controller switched to the refrigeration design temperature, temperature controller detected the temperature in the refrigerating chamber.If temperature controller control compressor 1 was out of service when the temperature in the refrigerating chamber reached the refrigeration design temperature, because unique characteristics and the refrigerant system configurations feature of above-mentioned refrigerating evaporator 41 make the temperature of refrigerating chamber can reach freezing design temperature when refrigerating chamber reaches the refrigeration design temperature.Otherwise if the temperature in the refrigerating chamber is higher than when refrigerating design temperature, temperature controller is then controlled compressor start.
