Dual-cycle system water-cooling air conditioning fan provided with static heat exchanger

Abstract

The invention discloses a dual-cycle system water-cooling air conditioning fan provided with a static heat exchanger. A water evaporation carrier (300) is mounted on the inner side of an air inlet / airoutlet of a shell (100) for cooling and humidifying, the static heat exchanger (650) is mounted on the inner side of the air outlet / air inlet, a water tank and a built-in water pump of the air conditioning fan are used for supplying water, two sets of water cycle mechanisms are formed, and the same sucked air flow is cooled two times and humidified one time. The heat exchanger (650) at least comprises a set of U-shaped pipes (651), and the outer walls of the U-shaped pipes (650) are connected with heat conduction pieces (653) in the radial direction. Water flows through the U-shaped pipes, the air flow which already penetrates the water evaporation carrier (300) and is cooled and humidified for the first time passes through gaps between the multiple heat conduction pieces (653) on the outer walls of the U-shaped pipes (651), is subjected to heat exchanger to be cooled again and then is blown out from the air outlet (120) to the surrounding. According to the air conditioning fan, the same air flow is subjected to water cooling of two times, and the refrigerating capacity is high; and the heat exchanger is used as another refrigerating means of the cycle system besides the water evaporation carrier, the structure is simple, and energy efficiency is high.

Description

technical field [0001] This invention relates to air conditioning and humidification, and more particularly to devices for humidifying and cooling ambient air by means of the evaporation of water in the air, and more particularly to having separate but common supply lines for hot and cold heat exchange fluids. The return pipeline involves a water-cooled air-conditioning device with a double-circulation system, and an air-conditioning fan equipped with a static water evaporation carrier cooling and humidifying component and a tubular heat exchanger component whose outer surface is connected to radial heat conduction fins. Background technique [0002] A water-cooled air-conditioning fan in the prior art includes a casing, a fan assembly, a water tank, a water pump assembly and a water evaporation carrier. The water evaporation carrier is arranged inside the air inlet of the housing, and is showered and supplied with water by the water tank and the water pump assembly. The ...

Problems solved by technology

However, in the prior art, only one set of water circulation cooling system is installed on the fan of the water-cooled air conditioner, and the cooling effect is limited.

In the hot and dry summer, the cooling effect is not obvious
