The invention discloses a water chilling unit capable of realizing indirect evaporative cooling. The water chilling unit comprises a direct evaporative cooling unit arranged in a housing a, wherein vertical tube indirect evaporative cooling units are symmetrically arranged on positions, at the two sides of the direct evaporative cooling unit, in the housing a; primary air inlets are separately formed in positions, on the side wall of the housing a, at the outer sides of the two vertical tube indirect evaporative cooling units; and surface coolers are separately arranged at the two sides, adjacent to the vertical tube indirect evaporative cooling units, of the direct evaporative cooling unit. According to the water chilling unit disclosed by the invention, vertical tubes are combined with two-stage indirect evaporative cooling sections of the surface coolers, relatively wide air runners outside vertical tube indirect evaporative cooling tubes are not liable to block; blockage in tubes can be effectively relieved as a result of automatic scouring effect of circulating water in the tubes; and a heat exchanger tube bundle adopts a vertical type, so that floor areas, in the horizontal direction, of heat exchange tubes can be reduced.
Description
technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to an indirect evaporative cooling chiller. Background technique [0002] With the development of economic construction, in order to alleviate the problem of urban traffic congestion, the subway industry has ushered in vigorous development. However, the air-conditioning equipment and systems used in the currently built subway stations generally have the problem of high energy consumption. When the subway station is cooled, the cooling water produced by the cooling tower is used to dissipate heat for the condenser of the mechanical refrigeration chiller. The area is well utilized, and the noise affects surrounding buildings. Contents of the invention [0003] The object of the present invention is to provide an indirect evaporative cooling chiller, which solves the problem of low COP of the mechanical refrigeration chiller in the prior art. [0004]...
