Abstract
The invention discloses a controlling method of an air condition which includes the compressor, the room heat exchanger, the room fan and the controlling device. The character is in that: the electrical heater is set on the upper side of the room heat exchanger. The controlling method includes at least the follow processes: heating, the electrical heater heats and dries the room heat exchanger; mix, the mixing wind circles in the room machine; heat rejection, discharge the hot wind out of the room machine. After the air condition refrigerating or sucking the humid, the invention uses the linkage of the electrical heater, the room fan and up-down fans. It not needs to start the compressor but can do the drying operation to make the evaporator dry and move the dirty of the fan surface to inhibit the bacterium growth in evaporator surface. So it can improve the heat exchanging effect and prolong the using life.
Description
Technical field
The present invention relates to the air-conditioner field, particularly air-conditioner is carried out the control method of automatic drying.
Background technology
Air-conditioner is in refrigeration or dehumidifier when running, and evaporimeter very easily condense dew or humidity cause bacteria breed, and evaporimeter are moist for a long time, and its surface is very easily sticked dust or is corroded, and then influences heat exchange effect and reduction of service life.
Existing air-conditioner will increase by an automatic drying function for addressing the above problem.The realization of this function generally is that a switch and a delay circuit are housed in the air-conditioning microprocessor, and the output of delay circuit is connected with drier by microprocessor.Drier is a fan electromotor (single cooler) or form (air conditioner), the Chinese patent CN2570667Y that has for example authorized by fan electromotor, compressor, cross valve normally.
But, for the drier of being made up of fan electromotor, because just drying is carried out in the air-supply running, so drying time is long, and can not carry out drying to evaporimeter more up hill and dale.And for the drier of forming by fan electromotor, compressor, cross valve, compressor will start in the dry run, because most of constant speed machine is that capillary dams, and the compressor operation frequency is certain, if heat with compressor and to carry out drying, be easy to cause overload, jumping stops, make it and can not heat continuously, operability is relatively poor.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of control method of air-conditioning, it can thoroughly and apace carry out drying to evaporimeter, and operability is better.
The object of the present invention is achieved like this: a kind of control method of air-conditioning, and this air-conditioning comprises compressor, indoor heat converter, indoor fan and control device at least, it is characterized in that: described indoor heat converter upstream side is provided with electric heater; Described control method comprises following sequential steps at least: heating steps, and electric heater carries out heat drying to indoor heat converter; Whipping step stirs hot blast it is circulated in indoor set; The heat extraction step is discharged indoor set with hot blast.
Also be provided with the air-supply step before the described heating steps.
Described electric heater is the PTC electric heater.
In described each step, compressor stops.
In the described air-supply step, the indoor fan running, electric heater stops, and indoor set blade is up and down opened.
In the described heating steps, indoor fan, electric heater running, indoor set blade is up and down opened.
In the described whipping step, indoor fan, electric heater running, indoor set is the blade closure up and down.
In the described heat extraction step, the indoor fan running, electric heater stops, and indoor set blade is up and down opened.
In described air-supply, heating, whipping step, the rotating speed of indoor fan progressively reduces.
The present invention is after air conditioner refrigerating or dehumidifier running, utilize indoor set electric heater, indoor fan, several parts such as blade link up and down, compressor need not be started and dry operating can be carried out automatically, make the indoor machine evaporation drying, and peel off the fin surface dirt, reach and suppress the evaporator surface bacteria breed, the effect that improves heat exchange effect and increase the service life.

The specific embodiment
The present invention is the control method that a kind of air-conditioning carries out automatic drying.As shown in Figure 1, this air-conditioner control device etc. of comprising compressor 7, outdoor heat converter 8, outdoor fan 9, indoor heat converter 3, indoor fan 5 and controlling the action of each parts.Be provided with electric heater 1 at indoor heat converter 3 upstream sides.Electric heater 1 adopts the PTC electric heater, can follow air quantity and change adjusting power output automatically, and operability is better.
Control method comprises following sequential steps: air-supply; Heating, 1 pair of indoor heat converter of electric heater 3 carries out heat drying; Stir, stir hot blast it is circulated in indoor set; Heat extraction is discharged indoor set with hot blast.In each step of whole dry operating process, compressor stops.Evidence should continue can kill mould in 4 minutes at 46 ℃ at least, and the present invention carries out heat drying with electric heater, can realize long continuous high temperature, reaches the good sterilization effect.
Embodiment
After cold-room or the dehumidifier running, carry out the evaporator dry running, at this moment as shown in Figure 2:
1) air-supply: as shown in Figure 3, indoor fan 5 turns round with high air quantity, electric heater 1 does not leave, blade 6 is opened up and down, the running of blowing, and time t1 continues about 5 minutes, purpose is to dry up attached to moisture on the evaporimeter as far as possible, reduce moisture, avoid vaporization phenomenon occurring, and make the drying effect of next step better once heating.
2) heating: as shown in Figure 4, carry out heat drying, electric heater 1 is opened, and its power is about 800 watts, and indoor fan 5 turns round with middle air quantity, and time t2 continues about 5 minutes, blows to the people for fear of hot blast simultaneously, and this moment, blade 6 preferably was in the extreme higher position up and down.
3) stir: as shown in Figure 5, this stage is the Hybrid Heating stage, electric heater 1 unlatching this moment, and its power is about 300 watts, blade 6 closures up and down, indoor fan 5 to be being lower than the heating period rotation speed operation, and makes hot blast get back to suction inlet soon, forms the air-flow short circuit, the hot blast that short circuit goes back carries out post bake to evaporimeter 31 and 32 parts, make that whole evaporimeter can thermally equivalent, and reduced air-flow and blow out the obvious noise that is obstructed and is brought that time t3 continues about 5 minutes.
4) heat extraction: as shown in Figure 6, indoor fan 5 turns round with high air quantity, and electric heater 1 cuts out, and blade 6 is opened up and down, the electrical heating property advanced waste heat is got rid of, and further dry evaporimeter, time t4 continues about 1 minute.
To time t1, t2, t3 and t4 decide desired value basically by experiment.If also be provided with the temperature sensor of the airflow temperature (temperature of for example drying, air draught temperature) that detects the indoor set air channel on this air-conditioner, can decide the required time of each step according to the temperature that compares this temperature and set.
