Abstract

The invention discloses a ceiling evaporating-cooling fresh air handling unit using a porous ceramic evaporative cooler, wherein an air channel is divided into an upper layer and a lower layer, a fresh air primary filter which passes through the upper layer of the channel and the lower layer of the channel is arranged at an air inlet, and a porous ceramic plate fin type indirect evaporative cooler which passes through the upper layer of the channel and the lower layer of the channel is arranged at the back of the fresh air primary filter; an air cooler I is arranged between the fresh air primary filter and the porous ceramic plate-fin indirect evaporative cooler in a primary air channel, and a water baffle plate and an exhaust fan are arranged at the back of the porous ceramic plate-fin indirect evaporative cooler in an air inlet direction; and the porous ceramic plate-fin indirect evaporative cooler, an air cooler II and an air feeding machine are arranged at the back of the porous ceramic plate-fin indirect evaporative cooler according in an air inlet direction in a secondary air channel. The air cooler, and the porous ceramic plate-fin indirect and direct evaporative cooler are formed into the fresh air handling unit, the set has compact structure and small land occupation space, and can be completely hung on the ceiling without limitation of high building storey.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and relates to an air-conditioning unit, in particular to an air cooler with cooling water from a cooling tower or an evaporative cooling type high-temperature chiller with high-temperature cooling water or sensible heat end return water, and a porous ceramic plate-fin type air cooler. A ceiling type evaporative cooling fresh air unit composed of an indirect evaporative cooler and a porous ceramic direct evaporative cooler. Background technique [0002] Evaporative cooling air-conditioning technology is an environmentally friendly, efficient and economical way to obtain cold energy through the heat and moisture exchange between water and air by using the natural moisture and renewable energy of dry air, with the help of the difference between the dry bulb temperature and the dew point temperature in the ambient air. The advanced cooling method has the advantages of ener...
