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 first temperature acquisition module 210 . The first temperature acquisition module 210 may be a temperature sensor to directly detect the temperature of the coil. The first 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 outdoor unit 300 has an outdoor heat exchanger 301 , an outdoor fan 302 , a compressor 303 , and a throttling device 304 . The outdoor fan 302 is used to drive the outdoor air f...

Abstract

The invention provides a refrigeration control method and a control device of an air conditioner. The refrigeration control method comprises the following steps that the coil temperature of an indoorheat exchanger of the air conditioner is acquired; the external environment temperature of an outdoor unit of the air conditioner is acquired; a frequency regulation rule is determined according to the coil temperature and the external environment temperature, and the frequency regulation rule is at least provided with an adjustment direction and an adjustment rate in a frequency regulation stage;and the operating frequency of a compressor of the air conditioner is adjusted section by section according to the frequency regulation rule, so that the coil temperature reaches a preset target temperature range. According to the refrigeration control method of the air conditioner, it is considered that loads of a system under the external environment temperatures of different outdoor units aredifferent during a refrigeration mode, the ascending and descending speed of the coil temperature is different, the adjustment rates of the operating frequencies of different compressors are set, andthe frequency rising and frequency reduction 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 refrigeration 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 refrigeration 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 ambient temperature of an outdoor unit of the air conditioner. ...
