Method and apparatus for cooling air by three-stage vapour cooling

Abstract

The invention relates to a three-level evaporating-cooling air-cooling method and a device. The method includes the following steps: (1) the air to be cooled firstly passes through meshed fillings and the clearances between meshed fillings are filled with water; (2) the air from the meshed fillings passes through an atomized zone formed by atomizing sprayers; (3) the air from the atomized zone passes through wet screen fillings immersed by water. After passing through the three-level device, dry bulbs in air have lower temperature; the three-level device can be adopted as an air cooling device. Simultaneously, the cooled air can enter an air-cooling condenser zone of an air conditioning device and a refrigerating device as a radiation medium for condensation and radiation. The device is formed by the meshed fillings, atomizing sprayers and wet screen fillings; wherein, the atomizing sprayers are positioned between the meshed fillings and the wet screen fillings; the atomizing sprayers form water smog under the normal water pressure of tap water so as to form the water smog zone between the meshed fillings and wet screen fillings. The invention can be independently adopted as an air cooling device or as an additional device of the air-cooling condenser of the air conditioning device and the refrigerating device to enhance the refrigeration capability of the air conditioning refrigerating devices and reduce energy cost.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to an air cooling method and equipment using water evaporative cooling technology; at the same time, it can be used as an air precooler for air-cooled condensers of various air-cooled refrigeration and air-conditioning equipment. Background technique [0002] At present, the application of evaporative cooling technology is quite extensive. This technology has no pollution to the atmospheric environment, and can directly use fresh air, which greatly improves the indoor air quality. The usual principle of mechanical refrigeration is to provide cooling capacity by the evaporation of refrigerant, but for evaporative cooling, it uses the evaporation of water to obtain energy. It does not need to compress the evaporated water vapor, condense it back to liquid water, and then proceed evaporation. Therefore, compared with mechanical refrigeration, eva...

Problems solved by technology

However, this system has the following disadvantages: slow cooling speed, large wind resistance, need to match more sets of fans, high cost, complex system, and requires major modifications to workshops and other places of use, and cannot be applied to open places, Make the scope of use subject to greater limitations

[0013] At present, most of the patents on evaporative cooling technology are for specific air conditioners, and it is impossible to retrofit various refrigeration and air conditioning equipment that has been produced or used so as to save energy for the original equipment.

Moreover, water pumps are needed to continuously circulate to keep the wet curtains moist, which increases the power consumption of the water pumps. At the same time, the water pumps are moving parts, which increases the failure points of the equipment.
