Embodiment Construction

[0035] 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 .

[0036] 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. 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 flow. The...

Abstract

The invention provides a control method and a control device for an air conditioner, wherein the control method comprises the following steps of: obtaining a coil temperature of an indoor heat exchanger of the air conditioner; obtaining accumulated running time of the air conditioner; determining a frequency adjustment rule according to the coil temperature and the accumulated running time, wherein the frequency adjustment rule defines at least one adjustment direction and an adjustment rate in a frequency adjustment phase; the operating frequency of a compressor of the air conditioner is adjusted step by step according to the frequency adjustment rule, so that the coil temperature reaches a preset target temperature range. The control method for the air conditioner provided by the invention sets the adjustment rate of different compressor operation frequencies in consideration of different system loads and different lifting speeds of the coil temperature under different accumulated running times, so that the up and down frequencies 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 accumulated operating time of the air conditioner. [0004] A further object of the present ...
