Purification control method of fresh air conditioner

Abstract

The invention belongs to the field of air conditioners and particularly provides a purification control method of a fresh air conditioner. In order to solve the problem that the fresh air conditioneris incapable of automatically completing PM2.5 concentration adjustment in a shutdown state, the control method comprises the steps that a preset startup moment and an outdoor environment temperatureof the fresh air conditioner are obtained, air conditioning time is determined, an early starting moment is determined, and when the early starting moment is reached, indoor PM2.5 concentration P1 andan indoor heat exchanger coil pipe temperature Ta are detected; the PM2.5 concentration P1 is compared with preset concentration Pa as well as the coil pipe temperature Ta is compared with a first set temperature T1; and when the P1 is larger than or equal to the Pa and the Ta is smaller than the T1, an air feeder is controlled to operate at a first set rotating speed V1, and a compressor is controlled to operate at first heating frequency f1. The PM2.5 concentration adjustment of the fresh air conditioner is controlled, so that the problem that the PM2.5 concentration adjustment of the freshair conditioner cannot be completed in the shutdown state is solved, and the early starting moment is enabled to be 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, ...
