The specific embodiment
To provide detailed description to details of the present invention with reference to accompanying drawing now.
In order briefly to describe with reference to accompanying drawing, identical or suitable parts will be provided with identical Reference numeral, and will not repeat its description.
Hereinafter, will control the method for temperature of refrigerator and use the preferred embodiment of the refrigerator of this method to set forth being used to.
Fig. 1 schematically shows the view of the structure of the refrigeration system of refrigerator according to an embodiment of the invention.
With reference to Fig. 1, the condenser 20 of the outlet that this refrigeration system comprises the compressor 10 that is configured to compressed refrigerant, be connected to compressor 10 and the triple valve 30 that is connected to the outlet of condenser 20.The first expansion cell 40a and the second expansion cell 40b are connected to two outlets of triple valve 30.The second expansion cell 40b has the big aperture than the first expansion cell 40a.
When cold-producing medium was directed into the first expansion cell 40a and the second expansion cell 40b, cooling capacity was maximum, and when cold-producing medium only was directed into the first expansion cell 40a, cooling capacity was minimum.When cold-producing medium was directed into the first expansion cell 40a and the second expansion cell 40b, power consumption was maximum, and when cold-producing medium only was directed into the first expansion cell 40a, power consumption was minimum.Therefore,, the first expansion cell 40a and the second expansion cell 40b both are opened, be used for quick cooling when the internal temperature of refrigerator during far above target temperature.Yet, when the internal temperature of refrigerator and the difference between the target temperature are little, cold-producing medium only is directed to first expansion cell so that reduce power consumption.Under these structures, can carry out optimal drive.
When in the scope of internal temperature at target temperature of refrigerator, compressor is stopped.When compressor was in halted state, the cold-producing medium with relative higher temperature and elevated pressures was retained in the compressor.This high-pressure refrigerant is introduced in the evaporimeter via condenser and expansion cell, thereby increases the internal temperature of evaporimeter.With rear drive the time, this temperature increases because the temperature that increases possibly need additional cooling down operation, causes the increase of power consumption.Therefore, when compressor 10 was in halted state, two outlets of closing triple valve 30 were introduced in the evaporimeter with the cold-producing medium that prevents high temperature and high pressure.
Except triple valve, the valve of the introducing that is used to prevent cold-producing medium can be additionally be installed between compressor and condenser.
Fig. 2 is the profile that schematically shows the refrigerator of the refrigeration system that adopts Fig. 1.With reference to Fig. 2, refrigerator 100 comprises the refrigerator body 102 with refrigerating chamber 110 and refrigerating chamber 120.Refrigerating chamber 110 is disposed in refrigerating chamber 120 tops.
Cold-air duct 130 is disposed in the place, two ends on the back surface of refrigerator body 102, and said cold-air duct 130 has the outlet 112 of refrigerating chamber 110 and the outlet 122 of refrigerating chamber 120.Be configured to the partition wall 104 that refrigerating chamber 110 and refrigerating chamber 120 are separated from each other is installed between refrigerating chamber 110 and the refrigerating chamber 120.Evaporimeter 50 is installed in the partition wall 104, and an end of partition wall 104 is communicated with cold-air duct 130.The cold air intake 114 that is communicated with refrigerating chamber and refrigerating chamber and 124 is arranged on the upper surface and lower surface of the other end of partition wall 104 respectively.
Blowing fan 60 is installed in the tie point place between partition wall 104 and the cold-air duct 130.Blowing fan 60 is implemented as the form of turbofan, and the air that said blowing fan 60 will in axial direction be introduced is to radially direction discharge.This can minimize the space that is occupied by blowing fan 60.Baffle plate 140 is installed in outlet 112 places of refrigerating chamber.Baffle plate 140 is constructed to opened or closed by the actuator (not shown) such as motor.
Hereinafter, will set forth being used to control according to the operation of the temperature of refrigerator of the present invention.
With reference to Fig. 3, measure temperature of refrigerating chamber (T
R) and freezer temperature (T
F) (S01).Then, with measured temperature of refrigerating chamber (T
R) and refrigerating chamber target temperature (T
RS) relatively (S02).If temperature of refrigerating chamber (T
R) be higher than refrigerating chamber target temperature (T
RS), then open outlet 112 (S03).On the contrary, if temperature of refrigerating chamber (T
R) be lower than refrigerating chamber target temperature (T
RS), then close outlet 112 (S04).
Under the opened state of outlet 112, with freezer temperature (T
F) and refrigerating chamber target temperature (T
FS) relatively (S05).If freezer temperature (T
F) be higher than refrigerating chamber target temperature (T
FS), then current step proceeds to S10, will set forth this step S10 hereinafter.On the contrary, if freezer temperature (T
F) be lower than refrigerating chamber target temperature (T
FS), then with temperature of refrigerating chamber (T
R) and refrigerating chamber target temperature (T
RS) between the same freezer temperature (T of difference
F) and refrigerating chamber target temperature (T
FS) between difference relatively (S09).
In outlet 112 buttoned-up states, with freezer temperature (T
F) and refrigerating chamber target temperature (T
FS) relatively (S06).If freezer temperature (T
F) be higher than refrigerating chamber target temperature (T
FS), then current step proceeds to S11, will set forth this step S11 hereinafter.On the contrary, if freezer temperature (T
F) be lower than refrigerating chamber target temperature (T
FS), then the temperature of refrigerating chamber and refrigerating chamber is all less than target temperature.Therefore, make compressor and blowing fan stop (S07), and close triple valve 30 (S08).
In S10 and S11, open triple valve according to the difference of measuring between temperature and the target temperature.As mentioned above, the aperture of expansion cell can be controlled as three types.Therefore, will be divided into the first to the 3rd humidity province, and open triple valve corresponding to each humidity province above the temperature range of target temperature.More specifically, when the control temperature is near first humidity province the target temperature, opens triple valve and make cold-producing medium only flow to first expansion cell.When the control temperature is in second humidity province, opens triple valve and make cold-producing medium only flow to second expansion cell.And, when the control temperature is in apart from farthest the 3rd humidity province of target temperature, open triple valve make refrigerant flow direction first and second expansion cells both.
Here, when the only temperature that has above target temperature in refrigerating chamber and the refrigerating chamber, corresponding temperature is as control temperature, fiducial temperature.Yet, when refrigerating chamber and two of refrigerating chambers all have the temperature above target temperature, have relevant temperature than big difference as the control temperature with target temperature.
In case opened triple valve, compressor and blowing fan just in S12 operation moving this refrigeration system, thereby carry out cooling down operation.Then, current step proceeds to S01, and said process repeats continuously or repeats with predetermined time interval.
