FRP cooling tower through evaporation to disperse a refrigeration and air conditioning equipment for industrial or waste heat generated. The basic principle is: after drying (low enthalpy) of air through the fan twitch from the inlet into the cooling tower at the net; the saturated vapor pressure of water molecules to large high-temperature low-pressure air flow, heat (high enthalpy) The water from the broadcast tower has been spilled into the water system. When the water droplets and air in contact, on the one hand due to the direct heat transfer contact with water in the air, on the other hand due to the presence of water vapor pressure difference between the surface and the air, is evaporated under the pressure of the phenomenon, i.e., by dry air with an unsaturated heat transfer away sensible heat of water, some water evaporation latent tropical water to go, so as to achieve the cooling water to cool the head. Closed cooling tower is the use of water and coil contact, passing away in the heat exchanger coil cooling refrigerant heat for cooling purposes through the wall of heat.
