Description

technical field

[0001] The invention belongs to the technical field of air conditioning and refrigeration, and relates to an evaporative chiller with air coolers connected in parallel and wind and water filtration, in particular to an evaporative cooling high-temperature chiller composed of an air cooler, a direct evaporative cooler, an air filter, and a water filter. chiller. 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 of dry air and renewable energy, with the help of the difference between the dry bulb temperature and the dew point temperature in the ambient air. cooling method.

[0003] At present, the evaporative cooling air-conditioning technology is mostly used in the centralized air-conditioning system. The centralized air-conditioning system has a large space oc...

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The evaporative water chiller of the present invention takes the evaporative cooling technology of the air cooler and the direct evaporative cooler as the core, adopts two-stage parallel air coolers to perform equal humidity cooling on the air, and adopts the two-stage parallel direct evaporative cooler to utilize air and The heat and moisture exchange of water takes away heat through the air to produce high-temperature cold water with a water temperature between the wet bulb temperature and the dry bulb temperature. The unit sets the air filter, two-stage parallel air cooler, two-stage parallel direct evaporative cooler, exhaust fan, air filter and water filter into an evaporative cold water combination of air cooler parallel connection, air filter and water filter unit.

[0023] Such as figure 1 As shown, in the evaporative chiller...
