Problems solved by technology

In addition, the air-water direct contact countercurrent heat exchanger used in the evaporative chiller is usually filled, which not only increases the system resistance, but also has defects such as easy blockage, aging, deformation, embrittlement, scale formation and bacterial growth.

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] The composite high-temperature water chiller of the present invention is composed of a water spray air cooler and a counterflow spray cooling tower without filler. figure 1 It is the embodiment of arranging the water spray air cooler and the counter-flow non-fill spray cooling tower in the same cabinet, showing the relative positions of the water spray air cooler and the counter-flow non-fill spray cooling tower.

[0016] Water spray air cooler 20 is made up of high temperature cold water air cooler 14 and circulating water spraying device 22, and circulating water spraying device 22 comprises nozzle 2 and water tank a13 that are respectively arranged on high temperature cold water air cooler 14 top and below, water tank The pipeline provided in a13 is connected with the nozzle 2 through the water pump a12, and the air inlet a1 is arra...

Abstract

The invention discloses a spray air cooler and packless spray cooling tower combined high temperature water chiller, which is formed by combining a spray air cooler and a counterflow packless spray cooling tower through pipe network connection. The spray air cooler consists of a high temperature cold water air cooler and a circulating water spraying device; and the upper part of the high temperature cold water air cooler is provided with an air inlet a, and exhaust air of the spray air cooler is taken as inlet air of the counterflow packless spray cooling tower. When the combined high temperature water chiller works in summer and outdoor air passes through the high temperature cold water air cooler, the outdoor air, the sprayed circulating water and the high temperature cold water in the high temperature cold water air cooler undergo sensible heat exchange and latent heat exchange, so on one hand, the heat exchange capacity of the air cooler is greatly improved and the outdoor air is effectively precooled; on the other hand, the air cooler is cleaned and the outdoor air is purified.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to a compound high-temperature chiller composed of a water-spraying air cooler and a counter-flow spraying cooling tower without filler. Background technique [0002] At present, the air-water counterflow heat exchangers used in evaporative chillers are usually dry air-water indirect evaporative air coolers. Due to the large amount of inhalable particulate matter in the outdoor air, the surface area of ​​the heat exchange tubes and fins of the air cooler It is full of dust and even fills the fin gap, which seriously affects the heat exchange efficiency. If a water spray air cooler is used, the situation will be quite different. The outdoor air and the air cooler are not only cleaned and purified, but also the process of outdoor air being treated is no longer a simple sensible heat exchange but a sensible heat exchange. There is also a process ...
