Abstract
The invention provides a refrigeration container and a control method thereof. The refrigeration container comprises a refrigeration system. The refrigeration system comprises a refrigeration branch and a cold storage branch which are connected with the two outlet ends of a bi-stable electromagnetic valve. The refrigeration branch and the cold storage branch are connected in parallel. Cold can be stored for a cold storage device through the cold storage branch by means of a gap, where refrigeration is not needed, of a refrigeration chamber, and a compressor halts on the premise that the temperature TR of the refrigeration chamber is lower than the set lower limit temperature TRD of the refrigeration chamber and the temperature TX of the cold storage device is also lower than the set lower limit temperature TXD of the cold storage device; then, the refrigerating capacity stored by the cold storage device supplies cold to the refrigeration chamber. The starting and stopping frequency of the compressor is decreased, and the service life of the compressor is prolonged; when people have a rest, the refrigeration chamber is refrigerated by means of the refrigerating capacity stored by the cold storage device, noise generated when a refrigeration system of a refrigerator works is eliminated, and the living quality of a user is improved.

xcontrol opening and closing of the start-stop of described compressor 31 and two ports of export (332,333) of described bistable electromagnetic valve 33.
Described controller and the first temperature sensor and the second temperature sensor are electrically connected.After opening cool storage function, whether first detect refrigerating chamber 11 temperature lower than temperature of refrigerating chamber lower limit T
rD, if not, then open the first port of export 332 operating refrigeration circuit of bistable electromagnetic valve 33; If so, then open bistable electromagnetic valve second port of export 333 and run cold-storage loop.In the process running cold-storage loop, the temperature of refrigerating chamber 11 to be detected the moment whether higher than temperature of refrigerating chamber upper limit T
rU, if not, then keep the opening state of second port of export 333, namely continue to run cold-storage loop; If so, then close second port of export 333 and open first port of export 332 simultaneously, namely close cold-storage loop, operating refrigeration circuit.
When temperature of refrigerating chamber T being detected
rlower than the temperature of refrigerating chamber lower limit T of setting
rD, cold-storage device temperature T simultaneously
xlower than cold-storage device lowest temperature T
xDtime, namely cold-storage device 2 cold-storage terminates, and now described controller control compressor 31 is shut down.After compressor 31 is shut down, carry out heat exchange by described cold-storage device 2 with refrigerating chamber 11, be supplied to certain cold to refrigerating chamber 11, slow down temperature recovery in refrigerating chamber 11.
Time compressor 31 is shut down, when being in nighttime users rest, in order to extend the time of the shutdown of compressor 31, by refrigerating chamber 11 temperature T
rwith than the temperature of refrigerating chamber upper limit T set
rUthe temperature of high 2 DEG C is made comparisons.As refrigerating chamber 11 temperature T
rthan the temperature of refrigerating chamber upper limit T of setting
rUwhen high 2 DEG C, described controller controls compressor 31 and starts shooting, and provides cold to refrigerating chamber 11 by refrigeration branch 34.When the temperature of refrigerating chamber lower limit T of the temperature in refrigerating chamber 11 lower than setting being detected
rDtime, described controller controls compressor 31 and shuts down.
Particularly, due in present embodiment, described refrigeration compartment 1 is refrigerating chamber 11, sets described temperature of refrigerating chamber lower limit T
rD=1 DEG C; Temperature of refrigerating chamber upper limit T
rX=8 DEG C; Cold-storage device lowest temperature T
xD=-4 DEG C.

S4: operating refrigeration circuit, enters S2;
After cool storage function is opened, if refrigeration compartment temperature does not reach refrigeration compartment lowest temperature T
rD, then first open refrigeration branch 34 and freeze to refrigeration compartment 1.
S5: compressor 31 is shut down;
At refrigeration compartment temperature T
rreach refrigeration compartment lowest temperature T
rDwhen, if cold-storage device temperature T
xalso cold-storage device lowest temperature T is reached
xDthen compressor 31 is shut down, and closes cold-storage loop simultaneously.Now corresponding is the time that night and user have a rest, and does not have the interference of noise, promotes the rest quality of user.
S6: detect refrigeration compartment temperature T
rwhether higher than refrigeration compartment ceiling temperature T
