Embodiment Construction

[0034] figure 1 is a schematic diagram of components of the air conditioner 100 according to an embodiment of the present invention. The air conditioner 100 of the embodiment of the present invention may generally include an indoor unit 200 and an outdoor unit 300 . The indoor unit 200 has an indoor heat exchanger 201 , an indoor fan 202 and an air deflector 203 . The indoor heat exchanger 201 has a coil, and the temperature of the coil can be acquired through the temperature acquisition module 210 . The temperature acquisition module 210 may be a temperature sensor to directly detect the temperature of the coil. The temperature acquiring module 210 may also be other devices capable of directly or indirectly acquiring the coil temperature. The indoor fan 202 is used to promote air flow to the room. The air deflector 203 is provided at the air outlet 205 of the indoor unit 200 , and the opening angle of the air deflector 203 can be obtained through the angle obtaining modul...

Abstract

The invention provides a control method and device for an air conditioner. The control method includes the following steps that the coil pipe temperature of an indoor heat exchanger of the air conditioner is acquired; the opening angle of an air guiding plate of an indoor unit of the air conditioner is acquired; the frequency adjusting rule is determined according to the coil pipe temperature andthe opening angle of the air guiding plate and at least specifies the adjusting direction and the adjusting rate in one frequency adjustment stage; the running frequency of a compressor of the air conditioner is adjusted stage by stage according to the frequency adjusting rule, so that the coil pipe temperature is in the preset target temperature range. According to the control method for the airconditioner, different adjusting rates for the running frequency of the compressor are set in consideration of different system loads and different rising and lowering speeds of the coil pipe temperature at different opening angles of the air guiding plate, so that frequency rising and frequency lowering of the compressor are more accurate.

Description

technical field [0001] The invention relates to the technical field of air conditioning devices, in particular to a control method and a control device for an air conditioner. Background technique [0002] The air conditioner can adjust and control the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building / structure. During the operation of existing air conditioners, the operating frequency of the compressor is raised and lowered at a fixed speed based on the temperature of the coil. Demand, the experience effect is poor, and it is easy to frequency up and down frequently, and even abnormal shutdown. Contents of the invention [0003] An object of the present invention is to provide a control method of an air conditioner that adjusts the operating frequency of a compressor based on the coil temperature of an indoor heat exchanger and the opening angle of an air deflector of an indoor unit. [0004] A further object of the presen...
