1 Energy Efficiency Ratio descends, and has a strong impact on refrigeration or heating effect;

2 power consumption quantitative changes are big: blower motor burns out indoor fan or outdoor compressor because of load expanded motor power rises, compressor produces big electric current because of high-low pressure pressure diminishes when serious, influences the service life of air-conditioning;

Tiny foreign material such as 3 dusts produce in fin and go mouldy, and multiply various bacteria under the moist environment, and peculiar smell is arranged, and influence the healthy of user.

And the clear great needs of traditional evaporimeter are torn machine installation open, not only need the cleaning means of special technical attendant and specialty, and utmost point labor intensive material resources, and expense height, cleaning are also very not in place.Evaporimeter just can't be accomplished to clean at all by domestic consumer.

Though being the recovery cleaning device of 94220045.4 Chinese patent refrigerating and air conditioning system condensing water, evaporimeter and the method for axial-flow leaf, 200420094421.7 a kind of anti-clogging central air-conditioning of the Chinese patent evaporimeter that 200510025316.7 Chinese patent cleans indoor apparatus of air conditioner, the patent No. also reported the air-conditioning cleaning, but the parts that they need add, structure complicated, influence traditional air-conditioning production technique structure, cost is also high, and is economical and practical inadequately.

Summary of the invention

Technical problem to be solved by this invention provides a kind of cleaning method of A/C evaporator, it need not special equipment, need not the professional and technical personnel, need not changer, this function only need be selected by domestic consumer, air-conditioner is just finished the cleaning of evaporimeter automatically by specific program requirement, method is simple, economical and practical, do not influence the processability of product structure of traditional air-conditioning.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of cleaning method of A/C evaporator is characterized in that refrigeration utilizes airborne steam in evaporator surface frosting or icing earlier; Heat then, become water after evaporator surface frost or ice are heated, take away dust or other tiny foreign material on surface.

Further improve, described evaporimeter is further dried ventilation, dries up the moisture that accumulates in the evaporimeter.

As preferably, the controller of air-conditioning in the described refrigeration, by sensing chamber's inner coil pipe temperature sensor thermistor, automatically constantly detect evaporator surface frosting or icing degree and whether reach the parameter of design in advance, simultaneously, whether cooling time reaches the designing requirement parameter, if reach, just makes the air-conditioning heating operation; Otherwise, continue refrigerating operaton.

The controller of air-conditioning constantly detects the evaporator surface defrost or changes the ice degree whether reach the parameter of design in advance automatically in described the heating, and simultaneously, whether the time that heats reaches the designing requirement parameter, if reach, just makes the air conditioner ventilation operation; Otherwise, continue heating operation.

Whether the controller of air-conditioning constantly detects ventilation time automatically and whether reaches the designing requirement parameter in the described ventilation, simultaneously, ventilate with the deep low gear wind speed operation of wind speed as presetting of design in advance, if reach, air-conditioning work is finished; Otherwise, continue the operation of ventilating.

Compared with prior art; the invention has the advantages that: utilize refrigeration principle; by refrigeration; heat and ventilation function combination utilization; make airborne aqueous vapor rapid condensation Cheng Shuan on the evaporimeter of air-conditioning; quick then defrost Cheng Shui; and oven dry and dry up evaporimeter; on the basis of conventional air-conditioning, need not to increase any parts and cost; need not artificial intervention; only need air-conditioning to require operation can reach the purpose of automated cleaning evaporimeter according to special program; kept the Energy Efficiency Ratio of air-conditioning; reduce power consumption; and make bacterium be difficult on evaporimeter, be survived and multiply; protected user's health; prolonged the service life of air-conditioning; method is simple, and is economical and practical, do not influence the processability of product structure of traditional air-conditioning.
