Air Conditioning for Paint Booths

Air Conditioning for Paint Booths

Working Principle

Air treatment principle: fresh air is introduced into the outside world through the fresh air section, filtered to remove dust and other impurities, and then enter the surface cooling section for cooling or heating to regulate the temperature, and at the same time in the humidification section, humidification or dehumidification operation is carried out according to the need, so that the air reaches the temperature and humidity required by the spraying process, and finally the processed air will be sent into the spraying room through the blower section.

Refrigeration and heating principle: In refrigeration, the compressor in the air conditioning system compresses the refrigerant into a high temperature and high pressure gas, which is cooled into a high pressure liquid by the condenser, and then enters into the evaporator through the throttling device to reduce the pressure, and then absorbs heat and evaporates to realize refrigeration in the evaporator to make the air cooled down. Heating can be achieved by electric heating, gas heating or heat pump, etc. For example, heat pump heating utilizes the inverse Carnot cycle to transfer the heat from the low-temperature environment to the room to achieve air warming.

Features

Large air volume: Paint spray booths need a large amount of air for ventilation in order to discharge the paint mist and harmful gases generated during the spraying process, and to ensure the cleanliness of the indoor air and the health of the workers, so air conditioners for paint spray booths are usually characterized by large air volume.

High-precision temperature and humidity control: different painting processes have strict requirements on the temperature and humidity of the environment, and spray booth air conditioners can accurately control the temperature and humidity to ensure the quality of painting.

Filtration and purification function: Equipped with high-efficiency filtration system, it can effectively filter dust, paint mist and other impurities in the air to provide a clean air environment for spraying paint and prevent impurities from adhering to the surface of the workpiece and affecting the effect of spraying paint.

Explosion-proof and anticorrosive performance: Considering the existence of flammable and explosive organic solvents and corrosive gases in the paint spraying room, some of the air conditioners in the paint spraying room have explosion-proof and anticorrosive functions to ensure safe operation.

Application Scenario

Automobile manufacturing and maintenance: automobile body painting has strict environmental requirements, spray booth air conditioning can provide appropriate temperature and humidity and clean air to ensure the adhesion, gloss and uniformity of the paint, and improve the quality of automobile appearance.

Furniture manufacturing: Furniture surface painting needs to be carried out in a stable temperature and humidity environment to prevent the paint surface from hanging, blistering, cracking and other problems, spray booth air conditioning helps to improve the quality of furniture painting and production efficiency.

Mechanical manufacturing: mechanical parts of the spray paint treatment also need good environmental conditions, spray paint booth air conditioning can ensure the stability of the spray paint process, so that the parts have good anti-corrosion and decorative properties.

Aerospace: the aerospace field of parts painting quality requirements are extremely high, spray booth air conditioning through precise control of environmental parameters to meet the needs of high-precision painting process, to protect the performance and reliability of parts.
