Closed evaporation cooling high-temperature cold water unit

Abstract

The invention discloses a closed evaporation cooling high-temperature cold water unit which comprises an evaporation cooling coil pipe, a filter I, a water distributing device I, a water blocking plate I and a fan, wherein the filter I, the water distributing device I, the water blocking plate I and the fan are sequentially arranged at the upper part; a group of pipe type indirect evaporative coolers are arranged outside both sides of the bottom of the evaporation cooling coil pipe; the upper part of each pipe type indirect evaporative cooler is sequentially provided with a filler II, a water distributing device II and a water blocking plate II; the lower part of each pipe type indirect evaporative cooler is provided with an opening type water tank II; the lower part of the evaporation cooling coil pipe is provided with an opening type water tank I, and the opening type water tank II and the opening type water tank I are separated by a barrier; the opening type water tank II is communicated with the water distributing device II by a pipeline; and the opening type water tank I is communicated with the water distributing device I by a pipeline. The unit can meet the requirement of the water temperature at a dry type or dry working condition sensible heat tail end, prevent a phenomenon of dew formation at the sensible heat tail end and conform to the requirement of the water temperature of an evaporation cooling semi-centralized type air-conditioning system in the northwest district.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and relates to an evaporative cooling high-temperature chiller, in particular to a closed evaporative cooling high-temperature chiller composed of a tubular indirect evaporative cooler and an evaporative cooling coil. Background technique [0002] Evaporative cooling air-conditioning technology is a cooling method that utilizes the natural wet energy 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, and through the heat and moisture exchange between water and air to obtain cooling capacity. Water has the ability to evaporate in the air. In the absence of other heat sources, the heat and moisture exchange process between water and air is: the air transfers sensible heat to water, which makes the temperature of the air drop, and due to the evaporation of water, not only the te...

Problems solved by technology

[0003] However, the existing high-temperature chillers cannot meet the water temperature requirements of the sensible heat end in dry or dry working conditions, and condensation occurs at the sensible heat end. At the same time, the circulating water of the chiller is easily polluted, and the pipeline corrosion is relatively serious. Not suitable for Northwest use where the air is dry
