Technical field
The present invention relates to refrigerator art, more specifically a kind of wind cooling refrigerator defrosting control method.
Background technique
Wind cooling refrigerator is otherwise known as frost-free refrigerator, its working principle is that: extraneous high temperature air, which flows through, to be set in refrigerator
The evaporator in portion carries out heat exchange, reduces the air themperature after heat exchange, and the cold air warp of temperature has been reduced after exchanging heat
Air duct is blown into refrigerator compartment, to achieve the purpose that refrigeration.In the above-mentioned course of work, the moisture in high temperature air encounters cold
Evaporator when can condense frosting on its surface, with using the time more long, easily lead to that refrigeration effect is bad, shortens refrigerator makes
Use the service life.
Steel pipe heater is arranged generally by portion under the vaporizers to the frost of air cooling refrigerator evaporator in the prior art, passes through
The mode of heat radiation and heat transfer melts the frost on evaporator, but the hot gas after defrost can largely reside in evaporator room and with steaming
In the air duct that hair device is connected, the heat that hot gas carries need to be freezed again by evaporator by evaporator room and the temperature inside the box drop
Low, this automatic defrosting mode needs to consume a large amount of energy consumption, namely results in the increase of wind cooling refrigerator defrost energy consumption.Therefore such as
What reduces this part defrost bring energy consumption, is the important topic that wind cooling refrigerator energy conservation needs to solve.
Summary of the invention
The present invention is to provide a kind of wind cooling refrigerator defrosting control method to avoid above-mentioned deficiency of the prior art,
To which the defrost energy consumption of wind cooling refrigerator can be reduced, to reduce energy consumption.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of wind cooling refrigerator defrosting control method, the wind cooling refrigerator include cabinet, have freezing compartment in the cabinet
And refrigerator room, each interior are respectively provided with the sensor for acquiring each compartment temperature, are located at the freezing in the cabinet
The back of compartment is equipped with evaporator room, is equipped with evaporator, the evaporation for sensing the evaporator temperature in the evaporator room
Device sensor, defrosting heater, fan one, fan two, fan three and the air duct one being arranged in a one-to-one correspondence with each fan, wind
Road two and air duct three, the air duct one are connected with the refrigerator room, and air duct one is equipped with air door, and the fan is once air duct
The cooling capacity that the evaporator generates is delivered to refrigerator room by one, the air duct two and air duct three respectively with freezing compartment's phase
Connection, the cooling capacity that evaporator generates is delivered to freezing compartment through air duct two and air duct three respectively by the fan two, fan three；
The defrosting control method is to carry out as follows:
S1, judge whether to meet defrost condition, if satisfied, then compressor is out of service and enters defrost, open refrigerator
Room air door starts fan one；Close other compartment fans in addition to refrigerator room；
S2, fan one are run, until evaporator sensor temperature reaches set temperature te, closing air door, fan one, startingization
White heater；-10℃≤te≤-5℃；
S3, judge whether to meet the set temperature that defrost is exited, if satisfied, then defrosting heater disconnects, into when dripping
Between；
Whether S4, judgement time of dripping terminate, if terminating, detect each compartment sensor temperature, and any compartment is up to booting
Point then opens compressor, opens air door, starts fan one, and refrigerator room starts to freeze；Then judge evaporator sensor temperature
Whether te reaches setting value td, if reaching, starts fan two and fan three, freezing compartment start to freeze；td≧-14℃.
As the preferred embodiment of above-mentioned control method, freezing compartment's inner wall is equipped with for acquiring freezing compartment
The sensor one of temperature, the refrigerator room inner wall are equipped with the sensor two for acquiring refrigerator room temperature.
Compared with the prior art, the invention has the advantages that:
1, multiple fans and air duct is arranged in the present invention in the evaporator room of wind cooling refrigerator, wherein the refrigeration of refrigerator room
By fan one, air duct one and airdoor control, the refrigeration of freezing compartment is controlled by fan two and air duct two, fan three and air duct three
System closes the fan two and fan three blown to freezing compartment before defrost starts, and opens air door corresponding with refrigerator room
With fan one, freezes using using evaporator waste cold to other compartments in addition to freezing compartment, refrigeration system is made full use of to freeze
Amount saves defrost and heats heat；
2, when entering normal refrigeration after defrost, each compartment of refrigerator opens refrigeration, extends refrigeration system high efficiency
Runing time, the topology layout setting of wind cooling refrigerator through the invention, cooperates defrosting control method, can effectively save air-cooled ice
Case is due to the increased energy consumption of refrigerator of defrost.
