The specific embodiment
Embodiment 1:
It comprises refrigerating chamber 5 and refrigerating chamber 2 and refrigeration system and control circuit refrigerator of the present utility model, wherein in refrigerating chamber 5 and the refrigerating chamber 2 temperature sensor is set respectively, control circuit comprises master control borad, display etc., and the temperature sensor in refrigerating chamber 5 and the refrigerating chamber 2 all links to each other with master control borad in the control circuit; Temperature compensation means is set in refrigerating chamber, this temperature compensation means links to each other with master control borad, temperature compensation means is a heater strip, heater strip is arranged on around the refrigerator evaporator, heater strip has two, one is arranged on evaporimeter top, another is arranged on the refrigerating chamber bottom surface of evaporimeter below, temperature sensor in the refrigerating chamber comprises evaporator temperature sensor 1, it is arranged on the evaporimeter of refrigerating chamber, temperature sensor in the refrigerating chamber also comprises space temperature sensor 3, and it is arranged on the sidewall of refrigerating chamber.
Referring to Fig. 1,2, be provided with a temperature of refrigerating chamber compensation arrangement in the circuit of the present utility model, the temperature of refrigerating chamber compensation arrangement is connected on the master control borad of refrigerator, is controlled by master control borad.The setting of temperature of refrigerating chamber compensation arrangement makes the open and close of the refrigerating chamber ACTIVE CONTROL compressor of the circulating refrigerator of low-cost single become possibility, its mechanism is such, set refrigerating chamber, temperature of refrigerating chamber control range and open and close compressor temperature scope in the main program and also had the temperature range of open and close temperature of refrigerating chamber compensation arrangement, suppose that it is 6.5 degrees centigrade that refrigerating chamber is opened the compressor temperature temperature, closing compressor temperature is 5.5 degrees centigrade; Refrigerating chamber is opened compressor temperature and is-13 degrees centigrade, and closing compressor temperature is-16 degrees centigrade; The turn-on temperature of temperature of refrigerating chamber compensation arrangement is 4.5 degrees centigrade, and shutoff temperature is 6 degrees centigrade.
The refrigeration system of refrigerator is to mate under the 25 degree conditions in environment temperature usually, and making the refrigerating chamber mean temperature is 5 degrees centigrade, and refrigerating chamber is lower than-18 degrees centigrade.Only controlling compressor with temperature of refrigerating chamber opened, stopped to guarantee that the refrigerating chamber mean temperature is 5 degrees centigrade this moment, and refrigerating chamber is lower than-18 degrees centigrade, and this relies on the refrigerator refrigeration system coupling to reach.Putting into heat load when refrigerating chamber raises temperature of refrigerating chamber, when being higher than refrigeration and setting 6.5 degrees centigrade of turn-on temperatures, refrigerator temperature sensor just passes to master control borad with this information, master control borad will send instructions to compressor, the compressor start, temperature of refrigerating chamber descends, when reaching 5.5 degrees centigrade of shutdown temperatures of refrigeration, refrigerating chamber space temperature sensor passes to master control borad with information again, master control borad sends instructions to compressor, compressor shutdown makes temperature of refrigerating chamber drop to setting range by prolonging the available machine time, and refrigerating chamber is along with the prolongation temperature of available machine time also can reduce; When refrigerating chamber is put into heat load when making freezer temperature be increased to refrigerating chamber turn-on temperature-13 degree centigrade; freezer temperature sensor also is delivered to master control borad with this information; master control borad sends instructions to compressor; the compressor start is freezed simultaneously to refrigerating chamber and refrigerating chamber; refrigerating chamber reaches when setting refrigerating chamber shutdown temperature-16 degree centigrade; master control borad can be controlled compressor shutdown; make freezer temperature drop to setting range by the prolongation available machine time like this, refrigerating chamber is along with the prolongation temperature of available machine time also can reduce.In the process of refrigerating chamber control compressor cooling; master control borad is also ceaselessly monitored the space temperature of refrigerating chamber; when being reduced to, temperature of refrigerating chamber sets the refrigerating chamber shutdown temperature below 5.5 degrees centigrade; when reaching the temperature of refrigerating chamber compensation arrangement and opening 4.5 degrees centigrade of temperature; master control borad will be controlled unlatching temperature of refrigerating chamber compensation arrangement is compensated temperature of refrigerating chamber; when temperature of refrigerating chamber reaches 6 degrees centigrade of temperature of refrigerating chamber compensation arrangement shutoff temperatures, the closing cold room temperature compensation means.The temperature of refrigerating chamber compensation arrangement is opened temperature to be set in below the refrigerating chamber shutoff temperature and can to reduce power consumption.
