Fresh air conditioner in paint shop and constant temperature and humidity control method thereof

Abstract

The invention discloses a fresh air conditioner in a paint shop and a constant temperature and humidity control methodthereof. The fresh air conditioner in the paint shop is provided with an air inletsection, a primary heating section, a humidifying section, a surface cooling section, a secondary heating section and an air supply section between an air inlet and an air outlet in sequence. Duringa transition season, the fresh air conditioner in the paint shop can humidify fresh air first, then the fresh air is humidified to afourth zone, then surface cooling, cooling and dehumidification andsecondary heating are performed to treat the fresh air into an air supply state for air supply. Regardless of whether the state of outdoor air is in a third zone or the fourth zone, the above processcan be used for processing the air, so that an operation mode of the transition season is adjusted to a processing mode, a control mode does not need to be switched, the frequent start and stop of a humidifier is avoided, the phenomenon of temperature and humidity imbalance in the air supply state in the transition season is avoided, the stability of the air supply in the transition season is ensured, and the fresh air conditioner is especially suitable for paint shops in the northern and with the transition season lasting longer.

Description

technical field [0001] The invention relates to a fresh air conditioner in a painting workshop, and at the same time relates to a constant temperature and humidity control method for the fresh air conditioner in a painting workshop, which belongs to the technical field of process air conditioners. Background technique [0002] The fresh air air conditioner in the painting workshop is a kind of technological central air conditioner, which needs to meet the air supply requirements of constant temperature and humidity during use. The functional sections of the fresh air conditioner in the painting workshop are usually arranged in the following form: air inlet section-primary effect filter section-natural gas heating section-surface cooling section-humidification section-secondary heating section-fan section-muffling section-medium effect filter section - Air supply section. For example, a Chinese utility model patent with a publication number of CN208804815U discloses a combin...

AI Technical Summary

Problems solved by technology

In the transitional season, when the outdoor temperature fluctuates back and forth between the ③ zone and the ④ zone, the fresh air air conditioner unit will switch back and forth between the two modes, and the humidifier will start and stop frequently

It takes a certain amount of time and process to start and stop the humidifier to adjust the humidification volume. This process will seriously affect the stability of the air supply state. As a result, the temperature and humidity of the supply air will be out of balance, and the goal of constant temperature and humidity cannot be achieved, thereby affecting production activities.
