Technical field
The present invention relates to technical field of refrigeration equipment, more specifically a kind of wind cooling refrigerator control method.
Background technology
Air-cooled, multi-temperature zone, big volume wind cooling refrigerator are the trend of refrigerator development.How the alternating temperature warm area of wind cooling refrigerator is realized
Function, while ensure machine energy-saving namely how to design cost-effective wind cooling refrigerator as the technical research of each refrigerator producer
An emphasis.
At present, wind cooling refrigerator realizes that become temperature function is mainly realized by following two modes：
1st, using multi-cycle system of freezing, realize that each compartment temperature is independently controlled by the switching control of freeze design and valve
System, takes into account each compartment temperature cooling condition, achievees the purpose that highly effective refrigeration.Alternating temperature compartment refrigeration cycle and air duct cycle are independent
, each compartment has the evaporator and ducting assembly of itself.But the shortcomings that such scheme, is that each compartment will have independence
Evaporator assemblies and air duct, occupy refrigerator space it is big, cause wind cooling refrigerator plot ratio low, it is of high cost；
2nd, it is mounted in refrigerating chamber using single evaporator, single fan, air duct main body and evaporator, refrigerating chamber, refrigerating chamber
Freezed with temperature sensor, refrigerating chamber and temperature-changing chamber is equipped in temperature-changing chamber by supply air duct and airdoor control.Such scheme
Shortcoming is that evaporator is in refrigerating chamber, and the refrigeration of temperature-changing chamber need to be realized by air door, is needed since the wind of temperature-changing chamber recycles
By air door, portion of energy is caused to lose, cause this type refrigerator refrigerating circulation less efficient, power consumption is high.
Invention content
The main object of the present invention is that the cooling air duct system component present in the above-mentioned prior art is big, occupies ice to avoid
Big, of high cost, refrigerating efficiency the is low deficiency in case space provides a kind of wind cooling refrigerator control method of high cooling efficiency.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of wind cooling refrigerator control method, applied in the wind cooling refrigerator comprising refrigerating chamber, temperature-changing chamber and refrigerating chamber, by such as
Lower step carries out：
Step 1, refrigerator power on, and temperature of refrigerating chamber is detected respectively by refrigerating sensor, freezing sensor, becoming temperature sensor
TC, freezer temperature TD, alternating temperature room temperature TB；
Whether step 2 judges temperature of refrigerating chamber TC up to starting point TCon, if so, opening compressor, opening freezing wind
Fan opens air door；Otherwise, step 3 is performed；
Whether step 3 judges alternating temperature room temperature TB up to starting point TBon, while acquires temperature-changing chamber setting state and perform step
Rapid 5；If TB reaches starting point TBon, open compressor, open alternating temperature fan；Otherwise, step 4 is performed；
Whether step 4 judges freezer temperature TD up to starting point TDon, if so, opening compressor, opening freezing wind
Fan；Otherwise, step 1 is performed；
Step 5, acquisition temperature-changing chamber setting state, if temperature-changing chamber set temperature LB >=0 DEG C, detecting alternating temperature room temperature TB is
It is no to be less than TR0, if so, compensating heater is opened, until TB >=TR1, closes compensating heater and wait until that TB reaches
TBon is then turned on compressor and alternating temperature fan；Otherwise, 3 are gone to step；Wherein, TR0 ＜ TR1 ＜ TBoff；
Step 6 judges that alternating temperature room temperature TB whether up to break point TBoff, if so, after closing alternating temperature fan, performs step
Rapid 8；Otherwise, alternating temperature fan is kept to open, after TB reaches break point TBoff, turns off alternating temperature fan, performs step 8；
Step 7 judges that temperature of refrigerating chamber TC whether up to break point TCoff, if so, after closing air door, performs step 8；
Otherwise, door opening is kept, after TC reaches break point TCoff, air door is turned off, performs step 8；
Whether step 8 judges freezer temperature TD up to break point TDoff, if so, close compressor, closing freezing wind
Fan, refrigeration terminate；Otherwise, compressor is kept to open, freezing fan unlatching, after TD reaches break point TDoff, turns off freezing
Fan and compressor, refrigeration terminate.
Compared with the prior art, the present invention has the beneficial effect that：
The present invention is distributed by the cold for controlling the start-stop of compressor and respective fans, air door that refrigeration system is adjusted flexibly,
And while change temperature function is realized, according to each compartment actual set and sensor temperature, the accurate keying for controlling compressor, energy
The effect of enough reducing the energy loss brought of high frequent keying, can not only playing refrigeration system to a greater extent, reaches pair
The utilization that cold is most abundant, optimizes, moreover it is possible to reach the energy-saving effect of high degree；Also, in the process freezed to temperature-changing chamber
Middle control of the cooperation to compensating heater, can be while user's big to temperature-changing chamber volume requirements be met, while are met accurate
Control the requirement of temperature-changing chamber.
