Control method of air-conditioning

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 [0001] The invention relates to the field of air conditioners, in particular to a control method for automatically drying the air conditioners. Background technique [0002] When the air conditioner is in cooling or dehumidifying operation, the evaporator is prone to condense dew or humidity, leading to the growth of bacteria, and the evaporator is humid for a long time, and the surface of the evaporator is easily adhered to dust or corroded, which will affect the heat exchange effect and shorten the service life. [0003] Existing air conditioner will increase an automatic drying function for solving the above problems. The realization of this function is generally that a switch and a delay circuit are installed in the air-conditioning microprocessor, and the output end of the delay circuit is connected with the drying mechanism through the microprocessor. Drying mechanism is usually a fan motor (single cooler) or is made up of fan motor, compressor, four-w...

AI Technical Summary

Problems solved by technology

[0004] However, for the drying mechanism composed of a fan motor, since it is only air-supplied for drying, the drying time is relatively long, and the evaporator cannot be dried thoroughly.

For the drying mechanism composed of fan motor, compressor, and four-way valve, the compressor must be started during the drying process. Since most of the fixed-speed machines are capillary cut-off, and the operating frequency of the compressor is constant, if the compressor is used for heating and drying, It is easy to cause overload, trip stop, so that it cannot be heated continuously, and the operability is poor
