Problems solved by technology

During the operation of the existing air conditioner with purification function, the operating frequency of the compressor is raised and lowered at a fixed speed based on the temperature of the coil. The response mode is single and there is no difference. To meet the needs of different usage environments, the experience effect is poor, and it is easy to frequently increase and decrease frequency, and even abnormal shutdown

Embodiment Construction

[0034] figure 1 It is a schematic diagram of components of an air conditioner 100 with purification function according to an embodiment of the present invention. The air conditioner 100 with purification function according to 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 , a purification unit 203 , and a driving mechanism 206 . 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 ...

Abstract

The invention provides a control method and a control device of an air conditioner with a purification function. The control method comprises the following steps of acquiring coiler temperature of anindoor heat exchanger of an indoor unit; acquiring a shielding condition of a purification assembly on an air inlet; determining a frequency adjustment rule according to the coiler temperature and theshielding condition, and at least stipulating an adjusting direction and an adjusting rate in one frequency adjustment stage according to the frequency adjustment rule; and adjusting operating frequencies of a compressor of the air conditioner stage by stage according to the frequency adjustment rule to enable the coiler temperature to reach a preset target temperature range. According to the control method of the air conditioner with the purification function, the facts that the shielding condition of the purification assembly on the air inlet are different , the loads on a system are different, the increasing and decreasing speeds of the coiler temperature are different are taken into consideration, the adjusting speed of different operating frequencies of the compressor is set, and thus the frequency ascending and frequency descending 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 with a purification function. 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. Due to people's higher and higher requirements for air cleanliness, there are currently some solutions for installing purification components in air conditioners, which purify part of the air entering the air conditioner. During the operation of the existing air conditioner with purification function, the operating frequency of the compressor is raised and lowered at a fixed speed based on the temperature of the coil. The response mode is single and there is no difference. To meet the needs of different usage environments, the experience effect is poor, and it is easy to frequently increase...
