Operating Principle of LNEYA Industrial Air Chillers

Industrial air cooler is a heat exchanger which USES air to cool the hot fluid. The hot fluid in the tube is heated through the exchange of heat between the tube wall, the fin and the outside air, which is usually supplied by the ventilator. Our Industrial Air Chillers SUNDI -45℃ ～ 250℃ can be applied to cooling and condensation such as

condensation of the top steam of oil refining and petrochemical industry, reflux oil, cooling of tower bottom oil, the cooling of various reaction products, cooling of circulating gas and condensing of steam turbine exhaust. Its working pressure can reach 69 mpa. However, the power consumption, noise, and floor area are large, and the cooling effect is greatly affected by climate change.

In order to avoid the heat medium affect the performance of medium because of long-term overheating, and to facilitate the storage or transportation, and to condense and distillate, we need to exchange heat of the medium. Usually, heat exchange equipment should be used to achieve the purpose of exporting, exchanging and cooling. When air is used as one kind of medium, this equipment is called air cooler.

Air cooler is widely used in petroleum, chemical industry, metallurgy and other industries as well as in the process industry.

Due to the low heat transfer coefficient of air and the high heat transfer coefficient of tube heat medium, their difference reaches several number grades, so we often use high fin in air cooler, close distance of double metal finned tube as the main heat transfer element. Heat through efficient heat exchange tube of the heat transfer medium is passed to the air which after accepting the heat temperature rises, at this time, the heat medium temperature drops, the air temperature rises, the hot air is directly emitted to the atmosphere to achieve the goal of decreasing the heat medium temperature.
