Problems solved by technology

However, due to the need to produce smaller water droplets, the nozzle aperture of the spray device is generally small, so it is easy to be blocked. Therefore, this direct evaporative cooler has higher requirements on water quality, and at the same time, the cost of the equipment is relatively increased.

Embodiment Construction

[0028] Such as figure 1 As shown, the design process of the spray-packing composite direct evaporative cooler of the present invention is as follows: determine the size of the direct evaporative cooler under the assumed head-on wind speed, and check the wind speed; select the filter material of the coarse filter section, and determine the filter material The size of the device; select and calculate the filler in the packing section, and determine the total water consumption of the direct evaporative cooler by the amount of water required in the spray section and the water required in the packing section; select and arrange the nozzles in the spray section; Calculate the size of the tank and size the pump and fan.

[0029] Such as figure 2 As shown, the spray-packing composite direct evaporative cooler includes a housing 13, an air inlet 3 and an air outlet 7 arranged outside the housing 13, a filter device arranged in the housing 13, a spray water tank 5, and a packing devi...

Abstract

The invention provides a spray-packing combined direct evaporative cooler which comprises a shell, an air inlet, an air outlet, a filter device, a spray water tank, a packing device, a fan and a sprayer, wherein the air inlet and the air outlet are formed outside the shell, the filter device, the spray water tank, the packing device and the fan are arranged in the shell, the fan is connected with the air outlet, PX type nozzles are adopted for spray heads of the sprayer, the hole diameter of each nozzle is 6 to 8 mm, the spray heads are divided into two rows, and a plurality of spray heads are arranged on each row; a baffle used for blocking spray and packing is arranged along the direction of the air outlet, and a hole which enables the spray to make into contact with the packing is formed in the baffle. The cooler plays a leading role in packing evaporative cooling in the spray-packing combined direct evaporative cooler, additionally, the defects of short contact time of air and the packing and low cooling efficiency are overcome, the spray performs a good supplementary effect on the packing, and the cooling effect on the air is increased.

Description

technical field [0001] The invention relates to a spray-filling composite direct evaporative cooler, which belongs to the field of evaporative cooling and refrigeration. Background technique [0002] The cooler is a novel air-conditioning equipment, which can treat the temperature of the outdoor air to close to the wet bulb temperature, and use the temperature difference between the dry and wet bulbs of the outdoor air to cool down the air, which has the advantages of energy saving, environmental protection, and health. At present, there are two types of direct evaporative coolers: packed and non-filled. [0003] 1. Filled direct evaporative cooler [0004] The packing type (organic, inorganic, aluminum foil, ceramic, etc.) direct evaporative cooler has a very simple structure, mainly composed of packing, water pump, fan, water collection tank and water supply system. The lower part of the equipment is equipped with a water collection tank. The circulating water is sent to...
