燃气型转轮与蒸发冷却、机械制冷复合的空调机

Abstract

燃气型转轮与蒸发冷却、机械制冷复合的空调机,包括机组内上下平行设置的新风通道和回风通道,新风通道内、依次设置新风口、初效过滤器a、转轮式换热器新风侧、露点式间接蒸发冷却器、直接蒸发冷却器a、挡水板a、制冷剂直接膨胀式空气冷却器、天然气再热器、送风机和送风口;回风通道内、依次设置有回风口b、初效过滤器b、压缩机、直接蒸发冷却器b、挡水板b、转轮式换热器回风侧、冷凝器、排风机和排风口。本实用新型空调机一套装置具有热回收、蒸发冷却与冷却去湿三种功能,采用了两级间接蒸发冷却的预冷处理,再加上一次回风系统,降低了新风负荷,使机组效率提高、能耗降低、耗电量大为减少。
The utility model discloses a gas type rotating wheel and evaporative cooling and mechanical refrigerating combined air conditioner. The air conditioner comprises a fresh air passage and an air return passage which are vertically arranged in parallel in a unit; a fresh air port, a primary filter a, a rotating wheel type heat exchanger fresh air side, a dew point type indirect evaporative cooler, a direct evaporative cooler a, a water baffle a, a refrigerant direct expansion type air cooler, a natural gas re-heater, a blower and an air supply port are sequentially arranged in the fresh air passage; and an air return port b, a primary filter b, a compressor, a direct evaporative cooler b, a water baffle b, a rotating wheel type heat exchanger air return side, a condenser, an exhauster and an exhaust port are sequentially arranged in the air return passage. The air conditioner has three functions of heat recovery, evaporative cooling and cooling moisture removal; and by adopting pre-cooling treatment of two stages of indirect evaporative cooling and using a primary air return system, the load of fresh air is reduced, so that the efficiency of the unit is improved, the energy consumption is reduced, and the power consumption is greatly reduced.
