Coil pipe-crossflow type dew point indirect and cold fog direct evaporative cooling hybrid air conditioner

Abstract

The invention discloses a coil pipe-crossflow type dew point indirect and cold fog direct evaporative cooling hybrid air conditioner. The coil pipe-crossflow type dew point indirect and cold fog direct evaporative cooling hybrid air conditioner comprises a unit shell, and the unit shell is internally divided into an upper air channel and a lower air channel which are arranged in an up-and-down manner; in the upper air channel, the two opposite side walls of the unit shell are provided with an air inlet a and an air exhaust respectively, and an air filter a, a packing type direct evaporative cooler, a water distributor b, a water baffle b and an exhaust fan are sequentially arranged between the air inlet a and the air exhaust; in the lower air channel, the two opposite side walls of the unit shell are provided with an air inlet b and an air outlet, and an air filter b, a coil-pipe high-temperature surface cooler, a dew point indirect evaporative cooler, a spraying unit, a water baffle c and a force draft fan are sequentially arranged between the air inlet b and the air outlet; and the packing type direct evaporative cooler is connected with the coil-pipe high-temperature surface cooler, and the dew point indirect evaporative cooler is connected with the water distributor b and the spraying unit separately. The coil pipe-crossflow type dew point indirect and cold fog direct evaporative cooling hybrid air conditioner can improve the dew point efficiency and achieve the humidifying function.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a coil-cross-flow type dew point indirect and cold mist direct evaporative cooling composite air conditioner. Background technique [0002] Dew point indirect evaporative cooling can theoretically reduce the temperature of the treated air to approach its dew point temperature, but currently limited by the technology itself and many factors in practical applications, the dew point efficiency of pure dew point indirect evaporative cooling is not high enough, and it cannot better control the temperature of the treated air. The humidity of the process air is properly adjusted. It can be seen that it is very necessary to improve the working performance of the existing dew point indirect evaporative cooler as a whole, further improve the dew point efficiency, and give it a certain humidification function to enhance the application ability of the dew point...
