Spraying and cooling device for condenser of water chilling unit

Abstract

The invention provides a spraying and cooling device for a condenser of a water chilling unit. A spraying device which consists of a plurality of spraying tubes is arranged at the top of the condenser which is connected with a compressor and an evaporator, wherein a water tube is connected above the spraying device; a cooling tank and a water storage tank are sequentially arranged below the condenser; during use, the spraying device can be used for uniformly spraying cold water into the condenser for cooling; the spraying device which can be used for uniformly spraying is adopted, so that the amount of cooling water can be effectively reduced, the heat exchange efficiency of the condenser is improved, and the electric energy consumption of water supply is correspondingly reduced.

Description

technical field [0001] The invention relates to a cooling device for a condenser of a chiller, in particular to a spray cooling device for a condenser of a chiller. Background technique [0002] The vapor compression refrigerated ammonia compressor used in the factory for cooling has a cooling device on the top of the condenser. The traditional cooling device is just a relatively thick water pipe, which sprays cooling water downward through the water pipe. This has been used for many years. There are two major problems in the use of traditional cooling devices. One is the large water consumption and high power consumption. Due to the large water consumption, the cooling pool below will often overflow and lose. The other is poor cooling effect. A uniform state cannot be formed during the time, so that the condenser cannot perform a good heat exchange state, resulting in frequent trips of the ammonia compressor, which directly affects normal production.

[0002] The vapor compression refrigerated ammonia compressor used in the factory for cooling has a cooling device on the top of the condenser. The traditional cooling device is just a relatively thick water pipe, which sprays cooling water downward through the water pipe. This has been used for many years. There are two major problems in the use of traditional cooling devices. One is the large water consumption and high power consumption. Due to the large water consumption, the cooling pool below will often overflow and lose. The other is poor cooling effect. A uniform state cannot be formed at the same time, so that the condenser cannot perform a good heat exchange state, resulting in frequent shutdown of the ammonia compressor, which directly affects normal production
