Multistage efficient evaporative cooling air conditioner air supply unit

Abstract

The invention discloses a multistage efficient evaporative cooling air conditioner air supply unit. The multistage efficient evaporative cooling air conditioner air supply unit comprises a cooling water preparation section and a multistage evaporative cooling section. An air cooler, an evaporative cooling chamber, a wet film and a traction fan are arranged in the multistage evaporative cooling section. Outdoor fresh air is exhausted from an air supply outlet of the multistage evaporative cooling section through the air cooler, the evaporative cooling chamber and the wet film in sequence undertraction of the traction fan. An atomizer is arranged in the evaporative cooling chamber. A cooling water outlet of the cooling water preparation section is connected to the atomizer through a pipeline. According to the multistage efficient evaporative cooling air conditioner air supply unit, by arranging the multistage evaporative cooling section, the unit can still prepare cooling water with thelow temperature even under the high-temperature environment condition so as to meet the requirement for the air supply temperature in summer. Meanwhile, the cooling water evaporation capacity is enhanced in the modes of cooling water indirect surface cooling, cooling water atomization evaporation and the like, and the problem that a traditional evaporative cooling unit is excessively limited by the outdoor air humidity is greatly solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a multi-stage high-efficiency evaporative cooling air-conditioning blower unit. Background technique [0002] "Green and efficient acquisition of a comfortable environment close to the natural state" is the general goal of the development of air-conditioning technology. Evaporative cooling refrigeration technology is widely used because of its environmental protection, high efficiency and economy. Compared with traditional evaporative-compression or absorption refrigeration air-conditioning systems, evaporative cooling air-conditioning systems may consume less energy to meet indoor cooling requirements, and evaporative cooling often only requires sufficient water to meet indoor cooling requirements. Refrigeration requirements, refrigeration methods are more environmentally friendly and economical. [0003] However, the conditions of use of the traditional e...

Problems solved by technology

[0003] However, the conditions of use of the traditional evaporative cooling method also have certain limitations. The cooling capacity of the air conditioning unit is very dependent on the temperature and humidity of the outdoor environment.

Furthermore, the temperature of the air from evaporative cooling is not easy to control, it also depends on the temperature and humidity level of the outdoor air

As the humidity of the outside air increases, the cooling capacity of the evaporative cooling system decreases. In humid climates, traditional evaporative cooling methods cannot even cool the supply air to a comfortable temperature.
