Cross flow type cooling tower for central air conditioner

Abstract

The invention discloses a cross flow type cooling tower for a central air conditioner. The cross flow type cooling tower comprises an air barrel, a tower body and a water receiving disc, wherein the air barrel is mounted above the tower body and is internally provided with a motor rack; a motor is mounted on the motor rack; the motor is connected with a draught fan through a speed-reducing box body; a draught fan silencer is mounted above the air barrel, and a water distribution pipe is mounted in the tower body and is connected with a water inlet pipe; a plurality of nozzles are mounted on the water distribution pipe; a combined type water sputtering disc is mounted under each nozzle; a packing net is mounted in the tower body and water spraying packing is arranged on the packing net; an air inlet window is mounted under the packing net; a plurality of air inlet blinds are mounted on the air inlet window and the water receiving disc is mounted at the bottom of the air inlet window; a water collection tank is mounted on the water receiving disc; and a sound insulation screen is mounted on the outer side of the water receiving disc. According to the cross flow type cooling tower, hot water sprayed out from the water distribution pipe is in sufficient contact with the water spraying packing, so that the cooling efficiency is improved; and meanwhile, the cooling tower has a good noise reduction effect and has the relatively slight noise pollution to the environment.

Description

【Technical field】 [0001] The invention relates to the technical field of central air-conditioning, in particular to the technical field of a cross-flow cooling tower for central air-conditioning. 【Background technique】 [0002] The central air conditioning cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the temperature of the water; its cooling is completed by the process of water evaporation and the cooling water can continue to circulate Use, in terms of economic benefits, virtually reduces the cost of waste. The cooling method of the cooling tower is to spray hot water onto the surface of the cooling material and contact with the moving air passing through it. At this time, sensible heat exchange occurs between the hot water and the cold air, and at the same time part of the hot water is evaporated, that is, the latent heat of evaporation in the evaporated water vapor is discharg...

AI Technical Summary

Problems solved by technology

The water sprayed by the water distribution system in the cooling tower in the prior art is not dispersed enough, and the hot water cannot be in full contact with the water spray filler, so the cooling effect needs to be improved; in addition, the noise sources of the water tower when the cooling tower is working mainly include the following aspects: 1 1. Windmill noise: its noise is mainly composed of mechanical noise and fluid noise; 2. Motor noise: it is mainly electromagnetic sound when the motor is running; 3. Water drop noise: 4. Ventilation noise: it mainly includes air fluid noise inside and outside the tower and Tower resonance noise

The cooling tower in the prior art lacks an effective sound-absorbing structure, and the equipment causes relatively large noise pollution to the environment
