The chiller cooling principle is: when the fan runs into the cavity to generate negative pressure, so that the air outside the machine flows over the surface of the porous wet curtain forcing the dry bulb temperature of the air over the curtain to drop close to the wet bulb temperature of the air outside the machine, that is, the dry bulb temperature of the chiller outlet is 5-12℃ lower than the outdoor dry bulb temperature (up to 15℃ in dry hot areas), and the hotter the air is dry, the greater the temperature difference, the better the cooling effect.

Because the air is always introduced into the room from outdoors, (at this time called positive pressure system) so it can keep the indoor air fresh; at the same time, because the machine uses the evaporative cooling principle, so the chiller has the dual function of cooling and humidification (the relative temperature can reach about 75%), used in textile, knitting and other workshops, not only can improve the cooling and temperature increase conditions, but also can purify the air, reduce the needle broken silk rate in the needle spinning process The quality of needle textile products can be improved.

Chiller unit is equipped with special materials around the honeycomb wet curtain, with a large surface area, through the water circulation system on the wet curtain constantly humidified; in the wet curtain chiller equipped with high-efficiency low-noise energy-saving fan, when the fan is running, wet curtain chiller of the negative pressure, so that the air outside the machine flows through the porous wet curtain into the machine, due to the evaporation of water on the wet curtain to absorb heat, forcing the air through the wet curtain cooling. At the same time, because the water on the wet curtain evaporates to the air flowing through the wet curtain, increasing the humidity of the air, so the wet curtain chiller has the dual function of cooling and humidification.

Chiller unit is no compressor, no cold coal, no pollution of environmentally friendly products, it is the use of outdoor fresh air evaporative cooling principle and indoor convection air exchange to achieve the purpose of indoor ventilation and cooling. Compared with the traditional compressor air conditioning system, the cost is less than half of it, and the equipment does not occupy any floor space. The system is simple, easy to quickly install and maintain, without professional maintenance personnel. It embodies the characteristics of energy saving, humanity, beauty, environmental protection, etc. It provides the perfect solution for ventilation and cooling in the environment of electronics, textile, shoes, plastic, machinery workshop, cigarette factory, modern family, office, supermarket, hospital, casino, waiting room, etc.
