Purification control method of ventilation conditioner

Abstract

The invention belongs to the field of air conditioners, and particularly provides a purification control method of a ventilation conditioner. The purification control method of the ventilation conditioner aims at solving the problem that a ventilation conditioner cannot automatically complete PM2.5 concentration adjustment in a shutdown state, the control method comprises the following steps thatthe preset starting moment and the outdoor environment temperature of the ventilation conditioner are obtained, the preset starting moment is corrected, the air conditioning time is determined, the advanced starting moment is determined, and when the advanced starting moment is reached, the indoor PM2.5 concentration P1 and the indoor heat exchanger coil pipe temperature Ta are detected; the PM2.5concentration P1 and the preset concentration Pa are judged as well as the coil pipe temperature Ta and the first set temperature T1 are judged; when P1 is larger than or equal to Pa and Ta is less than T1, the air feeder is controlled to operate at the first set rotating speed V1, a compressor is controlled to operate at the first heating frequency f1, by controlling PM2.5 concentration adjustment of the ventilation conditioner, the problem that the PM2.5 concentration adjustment of a ventilation conditioner cannot be completed in a shutdown state is solved, and the advanced starting momentis more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a purification control method for fresh air air conditioners. Background technique [0002] In a room with a relatively closed environment, there is often a high concentration of PM2.5, which makes the human body feel uncomfortable. The lower the concentration of PM2.5, the more comfortable breathing is. If the concentration of PM2.5 is high, it will make people feel uncomfortable in the respiratory tract. If things go on like this, it will cause irreversible damage to the human body. [0003] Fresh air conditioners with fresh air function have been used by more and more users. Usually, users will turn on the fresh air system and air conditioning system after returning home from get off work. However, due to long-term closed indoors, indoor PM2.5 concentrations may Higher, causing the user to feel chest tightness after returning home. [0004] Correspondingly, ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing fresh air air conditioner cannot independently complete the PM2.5 concentration adjustment in the shutdown state, the present invention provides a purification control method for the fresh air The air conditioner includes a fresh air system and an air conditioning system, the fresh air system includes a blower, the air conditioning system includes a compressor and an indoor heat exchanger, and the control method includes:
