Spray water distribution system in plate-type indirect evaporative cooling system

Abstract

The invention relates to an air adjustment system by utilizing a plate-type air-air heat exchanger to indirectly evaporate and cool used in the heating ventilating and air conditioning field, in particular relates to a water system part of the system, and especially emphasizes an efficient and endurable spray water distribution subsystem in the water system. The water distribution rate improvement has vital function for improving the heat exchange efficiency and the refrigerating capacity. Meanwhile, the system has important function on sealing, corrosion prevention, scale prevention, blocking prevention, biohazard prevention and the endurable operation of the system in the water system in the opening environment. In the water distributor provided by the invention, a long and thin pipe consistent with the opening cross section of each evaporation channel is adopted as a water spray pipe which is provided with two rows of water spray holes; all the evaporation channels of the whole heat exchanger are fixedly sprayed correspondingly by a plurality of water spray pipe or a water spray pipe scanned by a track; evenly continuous water films are formed on each wall face of the heat exchanger; and the water distributing system is applied to the air-conditioner system of plate-type indirect water evaporation and cooling.

Description

technical field [0001] The invention relates to a system in the field of heating, ventilating and air-conditioning that utilizes plate air-air heat exchangers for indirect water evaporative cooling for air conditioning, specifically relates to the water system part of this system, and especially emphasizes the efficient and durable spray water distribution in the water system system. Background technique [0002] At present, the known air conditioning system includes two parts: air quality treatment and air temperature and humidity adjustment. The main air temperature adjustment system technologies include compression evaporation system, steam absorption system and normal temperature and pressure water evaporation system. Water evaporative cooling system is divided into direct water evaporative cooling system and indirect water evaporative cooling system. The indirect evaporation system mainly includes tube heat exchanger system, plate heat exchanger system and heat pipe h...

AI Technical Summary

Problems solved by technology

[0030] In the known related products and technical solutions, the sprinkler subsystem in the water system simply uses some nozzles installed on the water delivery pipe, and each nozzle sprays water in the form of an umbrella surface, and some of them are atomized. Sparse and discrete nozzles do not match the large number of plates, narrow spacing between plates and different orientations of plate heat exchangers. It is impossible to evenly cover the entire plate surface with water, and it is impossible to form a thin layer on the entire plate surface. , Uniform water film, the water distribution area can only reach 10-50% of the plate heat exchanger's water distribution area

In order to increase the water distribution area, simply increasing the water spray volume will not help. The atomized water spray will also cause the atomized water droplets to be directly taken out of the system by the airflow, which greatly increases the water consumption.
