Description
Technical field
The invention belongs to air-conditioner defrosting technical field, in particular it relates to a kind of domestic air conditioning defrosting control method.
Background technology
Air-conditioning is air regulator（Air Conditioner）.Refer to manually means, to environment in building/structures
The process that the parameters such as the temperature of air, humidity, cleanliness factor, speed are adjusted and controlled.
Generally comprise the several majors such as low-temperature receiver/heat resource equipment, cold and hot medium distributing system, end equipment and other auxiliary are set
It is standby.Mainly include water pump, blower fan and pipe-line system.End equipment then be responsible for using transmission ＆ distribution come cold and hot amount, specifically processing air,
Temperature, the air parameter of target environment is set to reach requirement.
The species of domestic air conditioning is divided into many kinds, wherein common includes wall-hanging air conditioner, vertical air conditioner, window sky
Mediation ceiling type air conditioner, but these products respectively have feature, price is also different, to be selected according to the demand of oneself.
The structure of air-conditioning includes：Compressor, condenser, evaporator, four-way valve, check valve capillary module composition.Air-conditioning
It is divided into single cold air-conditioning and air conditioner for both cooling and heating, operation principle is the same, and the refrigerant typically used mostly before air-conditioning is fluorine
Leon.The characteristic of freon is：When being changed into liquid from gaseous state, substantial amounts of heat is discharged.And when being changed into gaseous state by liquid, meeting
Absorb substantial amounts of heat.（The i.e. first re-liquefied heat release of endothermic gasification）Air-conditioning be exactly accordingly principle and design.
Air-conditioner defrosting refers to air-conditioning in refrigeration and heating, is likely to produce frost, is such as removed after air-conditioning frosting
Frost not in time, will influence the use of air-conditioning.If defrosting not in time, easily produces following adverse consequences after air-conditioning frosting：It is stifled
Passage between plug fin, increases air flow resistance；Increase heat exchanger thermal resistance, exchange capability of heat declines；Evaporating temperature declines, Energy Efficiency Ratio
Reduce, operation of air conditioner penalty, until cisco unity malfunction.
Defrosted for domestic air conditioning, the current country is primarily present following patent document：
China Patent Publication No.：CN106958923A, disclose a kind of control method and device of air conditioner defrost.Wherein, it is empty
Adjusting the control method of device defrost includes：Whether detection air conditioner meets to enter defrost condition；When detecting to meet the entranceization
During ice-lolly part, the air conditioner is controlled to enter defrost pattern；Under defrost pattern, according to the air-breathing of the compressor of the air conditioner
The degree of superheat adjusts the running frequency of the compressor.The present invention solves prior art and defrost consumption in the case where frosting is thicker be present
When the longer and sordid phenomenon of defrost, longtime running will cause larger attenuation problem to the heating capacity of unit, optimize
System returns the problem of liquid during defrost, efficient defrost contracting shortens the defrost time as far as possible, reduces the temperature drop that long-time defrost is brought, so as to
Improve the comfortableness that user uses.However, the defrosting control method that the patent is provided, defrosting condition is indefinite, insufficient.
The content of the invention
To solve above-mentioned problem, it is an object of the invention to provide a kind of domestic air conditioning defrosting control method, institute
It is abundant to state control method defrosting condition, considers diversified forms defrosting situation, control is simple, easy to operate, and air-conditioning can be entered in time
Row defrosting is handled, and ensures air-conditioning trouble-free operation, reduces the adverse effect that high temperature is brought to human body, lifts comfort level.
To reach above-mentioned purpose, the technical scheme is that：
A kind of domestic air conditioning defrosting control method, the control method comprise the following steps：Set air-conditioner defrosting condition；Sensing chamber
Inner coil pipe temperature, monitoring temperature change, when indoor coil pipe change meets defrosting condition, control air-conditioning enters defrosting mould
Formula；When being unsatisfactory for defrosting condition, control air-conditioning exits defrosting mode；Decline 1 ~ 2 DEG C within every 3 ~ 5 minutes when indoor coil pipe,
It is continuous 2 ~ 3 times decline, and it is outdoor coil pipe used be less than 40 DEG C, meet defrosting condition, into defrosting mode.
Further, the continuous high loaded process of the air-conditioning 50 ~ 60 minutes and when indoor coil pipe is less than 35 DEG C, into except
White pattern.
Further, compressor operating time is monitored, compressor continuous operation time is more than or equal to compressor operating time
When setting value and indoor/outdoor temperature-difference are reached less than temperature difference setting value, the air-conditioning is controlled to enter defrosting mode.
Further, the compressor operating time setting value is 1.5 ~ 2.5 hours.
Further, the temperature difference setting value is 10 ~ 15 DEG C.
Further, the air-conditioning is 1.5P, and high loaded process is that compressor horsepower reaches 900 ~ 1000W.
Further, it is less than 40 DEG C when indoor coil pipe continuous 2 ~ 3 hours, controls the air-conditioning to enter defrosting mode.
The beneficial effects of the present invention are：
The control method defrosting condition is abundant, considers diversified forms defrosting situation, control is simple, easy to operate, can be right in time
Air-conditioning carries out defrosting processing, ensures air-conditioning trouble-free operation, reduces the adverse effect that high temperature is brought to human body, lifts comfort level.
