Embodiment Construction

[0033] 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 and an indoor fan 202 . 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, and the wind speed of the indoor fan 202 can be obtained through the wind speed acquisition module 220 . The outdoor unit 300 has an outdoor heat exchanger 301 , an outdoor fan 302 , a compressor 303 ...

Abstract

The invention provides a control method and a control device of an air conditioner. The control method comprises the following steps that the coil temperature of an indoor heat exchanger of the air conditioner is acquired; the wind speed of an indoor fan of the air conditioner is acquired; the frequency adjusting rule is determined according to the coil temperature and the wind speed, and the frequency adjusting rule at least stipulates the adjusting direction in the frequency adjusting stage and the adjusting rate; and the operating frequency of a compressor of the air conditioner is adjustedby section according to the frequency adjusting rule, so that the temperature of a coiled pipe reaches a preset target temperature range. According to the control method of the air conditioner, different loads of the system under different wind speeds are considered, and the lifting speed of the coil temperature is different, so that the frequency rising and frequency reduction of the compressorare 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 for an air conditioner that adjusts the operating frequency of a compressor based on the coil temperature of an indoor heat exchanger and the wind speed of an indoor fan. [0004] A further object of the present invention is to optim...
