The refrigeration control method according to the refrigerator of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing 3-5.
Fig. 3 is the flow chart of the refrigeration control method of refrigerator according to an embodiment of the invention.As shown in Figure 3, the refrigeration control method of refrigerator according to an embodiment of the invention, comprises the following steps:
Step S301, whether the refrigerating chamber detecting refrigerator meets cryogenic conditions.Specifically, first detect the Current Temperatures of freezer compartment of refrigerator, Current Temperatures is designated as Tf; Then whether compare the Current Temperatures of refrigerating chamber higher than refrigerating chamber turn-on temperature, refrigerating chamber turn-on temperature is designated as Tfk, whether namely compares Tf greater than or equal to Tfk; If Tf >=Tfk, then judge that refrigerating chamber meets cryogenic conditions.
Step S302, if meet cryogenic conditions, starts compressor and freezes to refrigerating chamber, and detect in this compressor operating process room between at least one in cold compartment of refrigerator and temperature-changing chamber whether ask refrigeration.Namely after judgement refrigerating chamber meets cryogenic conditions, compressor is opened, and freezes to refrigerating chamber, and in process of refrigerastion, whether detection refrigerating chamber and temperature-changing chamber also ask refrigeration.Specifically, whether ask the concrete grammar that freeze be: detect the Current Temperatures Ts of temperature-changing chamber if detecting temperature-changing chamber, and judge when whether temperature Ts is higher than the break point temperature Tst of temperature-changing chamber, if, i.e. Ts>Tst, then judge temperature-changing chamber request refrigeration; Whether ask the concrete grammar that freeze be: detect the current Current Temperatures Tr of refrigerating chamber if detecting refrigerating chamber; and judge that whether the Current Temperatures Tr of refrigerating chamber is higher than its startup-shutdown mean temperature Trm; if so, i.e. Tr>Trm, then judge refrigerating chamber request refrigeration.The turn-on temperature of such as refrigerating chamber is 6 DEG C, and shutdown temperature is 2 DEG C, then the startup-shutdown mean temperature Trm of refrigerating chamber is 4 DEG C.
Step S303, if at least one room request refrigeration, then judges whether at least one room is ask refrigeration first in this compressor operating process.Whether namely in compressor operating process, when room request is freezed between at least one in temperature-changing chamber and refrigerating chamber, then judge that this at least one room runs in closing process after compressor is opened, be ask refrigeration first.Wherein, at least one room request refrigeration to refer in temperature-changing chamber and refrigerating chamber request refrigeration in room between at least one, such as: temperature-changing chamber request refrigeration and refrigerating chamber do not ask refrigeration or temperature-changing chamber not to ask refrigeration and refrigerating chamber request refrigeration or temperature-changing chamber and refrigerating chamber all to ask refrigeration.
Step S304, if for asking refrigeration first, then freezed at least one room simultaneously, and after having freezed at least one room, judges whether refrigerating chamber meets refrigeration stop condition.Namely when judging that at least one room is as after request refrigeration first, then also freezed at least one room to while refrigerating chamber refrigeration, and in temperature-changing chamber and refrigerating chamber between at least one room available machine time in running shorter, therefore cooling time shorter (realizing by evaporimeter indoor between allotment).Specifically, in process of refrigerastion, when judging temperature-changing chamber Current Temperatures Ts less than or equal to shutdown temperature Tst, then judge that temperature-changing chamber has freezed; When judging refrigerating chamber Current Temperatures Tr less than or equal to its startup-shutdown mean temperature Trm, then judge that refrigeration chamber completes.And after having freezed at least one room, then continue to judge whether refrigerating chamber meets refrigeration stop condition.Specifically, when the Current Temperatures of refrigerating chamber is less than or equal to refrigerating chamber shutdown temperature, then judge that refrigerating chamber meets refrigeration stop condition.Such as: refrigerating chamber shutdown temperature is Tft, namely as Tf≤Tft, refrigerating chamber meets refrigeration stop condition.
Further, in this compressor operating process, when at least one room ask first refrigeration and after completing refrigeration, if refrigerating chamber and/or temperature-changing chamber ask refrigeration again, then compressor does not freeze to refrigerating chamber and/or temperature-changing chamber, namely, in once complete compressor operating process, refrigerating chamber and/or temperature-changing chamber freeze at most once.
Step S305, if it is controls compressor shutdown to terminate this compressor operating process, otherwise continues to freeze to refrigerating chamber until when refrigerating chamber meets refrigeration stop condition, controls compressor shutdown.In other words, if when refrigerating chamber meets refrigeration stop condition, then close compressor is to stop refrigeration; If refrigerating chamber does not meet refrigeration stop condition, then compressor continues to freeze to refrigerating chamber until after refrigerating chamber satisfied refrigeration stop condition, control compressor and cut out, and stops freezing.
Fig. 4 is the steady-state operation curve map of the refrigeration control method of refrigerator according to an embodiment of the invention.
Particularly, under the steady state mode of operation control law of refrigerator enters:
A: the control of compressor: compressor is only controlled by refrigerating chamber, refrigerating chamber and temperature-changing chamber can not control the start-stop of compressor.Current Temperatures Tf >=Tfk(starting point temperature when refrigerating chamber) time, compressor is opened, and freezes to refrigerating chamber; When Current Temperatures Tf≤Tft(break point temperature) time, compressor shutdown.
B: the refrigeration control of temperature-changing chamber and refrigerating chamber:
Temperature-changing chamber: the Current Temperatures Ts > Tst(break point temperature when temperature-changing chamber) time, temperature-changing chamber request is freezed; As Ts≤Tst, refrigeration terminates.
Refrigerating chamber: the Current Temperatures Tr > Trm(startup-shutdown mean temperature when refrigerating chamber) time, refrigerating chamber request is freezed; As Tr≤Trm, refrigeration terminates.
Be opened in the cycle of operation of shutdown at compressor, refrigerating chamber and temperature-changing chamber freeze at most once.
The unlatching of compressor controls by refrigerating chamber, and preferentially ensures the refrigeration of refrigerating chamber after compressor is opened, because refrigerating chamber and/or the temperature-changing chamber available machine time in running is short, so each compressor only to a refrigerating chamber temperature-changing chamber refrigeration once.And in same compressor operating process once, when refrigeration asked again by temperature-changing chamber and/or refrigerating chamber, compressor does not freeze to it.
In addition, this controlling functions needs the coupling of refrigeration system, and cold when ensureing compressor start can balance the multiple cool room of supply.
Composition graphs 4 can be found out, carry out refrigeration control by the method for the embodiment of the present invention to refrigerator, curve 1 shows start-stop and compares rule, thus can reduce the Homes Using TV of compressor, thus plays energy-conservation object, extends the service life of compressor simultaneously.
