Gravity-heat-pipe-combined stand pipe indirect evaporative cooling water chilling unit

Abstract

The invention discloses a gravity-heat-pipe-combined stand pipe indirect evaporative cooling water chilling unit which comprises a unit housing. An upper air flue and a lower air flue distributed up and down are formed in the unit housing; the upper air flue is structurally characterized in that exhaust outlets a are formed in two opposite side walls of the unit housing; the lower air flue is structurally characterized in that air inlets are formed in the two opposite side walls of the unit housing; a direct-indirect evaporative cooling unit is arranged in the center in the lower air flue; gravity heat pipes are symmetrically arranged on the left side and the right side of the direct-indirect evaporative cooling unit; evaporation sections of the gravity heat pipes are located in the lowerair flue; condensation sections of the gravity heat pipes are located in the upper air flue; coarse filtering sections are arranged between the evaporation sections of the two gravity heat pipes and the air inlets in the corresponding sides; and an exhaust outlet b is formed in the top wall of the lower air flue corresponding above the direct-indirect evaporative cooling unit. According to the evaporative cooling water chilling unit provided by the invention, multiple running modes can be switched according to the weather conditions, so that the power consumption of the equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a standpipe indirect evaporative cooling water chiller combined with a gravity heat pipe. Background technique [0002] With the development of economic construction, a large number of various industrial buildings are built, but the air-conditioning equipment and systems used in domestic buildings currently have the problem of high energy consumption. In recent years, some industrial buildings have higher and higher indoor temperature and humidity requirements, such as textile factories, production workshops, data centers, etc. When cooling in these areas, traditional mechanical refrigeration chillers are used for separate cooling, which consumes a lot of power and requires high operation and maintenance costs. Moreover, the temperature of cold water produced is often lower than the dew point temperature of the indoor air, and the cold water is pass...

Problems solved by technology

But in fact, due to the influence of outdoor meteorological conditions, the refrigeration performance of evaporative cooling chillers is unstable, and the structural size of the unit is large, which cannot make good use of the cold wind generated while producing cold water.
