Pre-cooling spray evaporation type condenser

Abstract

The invention discloses a pre-cooling spray evaporation type condenser. A pre-cooling heat exchange fin coil and two groups of condensation heat exchange fin coils are arranged in a condenser shell, and the two groups of condensation heat exchange fin coils are arranged in the condenser shell in a V shape; a refrigerant is circulated in a pipe of the pre-cooling heat exchange fin coil and pipes ofthe condensation heat exchange fin coils, water mist spray devices are located on the two sides of the two groups of condensation heat exchange fin coils, and an air outlet device is located at the top of the condenser shell. The condenser has the advantages that sprayed water mist is uniformly attached to and makes full contact with the surfaces of fins and the surfaces of the coils along with flowing of air for heat absorption and evaporation, the heat of the refrigerator in the condensation heat exchange fin coils is brought away, the heat exchange efficiency is high, and the size of equipment is small; the pre-cooling heat exchange fin coil pre-cools and cools the refrigerant entering the condensation heat exchange fin coils, the scaling efficiency of the condensation heat exchange fin coils is reduced, the later maintenance work is reduced, and meanwhile the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of condensers, in particular to a precooling type spray evaporation condenser. Background technique [0002] The condenser is a component of the refrigeration system and belongs to a type of heat exchanger. Its function is to convert the high-temperature and high-pressure gaseous working medium in the refrigeration system into a normal temperature and high-pressure liquid working medium. There are three main types of conventional condensers on the market: air-cooled condensers, water-cooled condensers and evaporative condensers. [0003] In the household air conditioner, the household air conditioner condenser is a kind of air-cooled condenser. The heat release process is to exchange heat between the condenser heat exchange fin coil and the air forcibly convective, and the refrigerant in the condenser changes. Become a liquid working medium at room temperature and high pressure. Because the heat in the air...

Problems solved by technology

For a long time, traditional cleaning methods such as mechanical scraping or brushing, high-pressure water, chemical cleaning and pickling have caused many problems when cleaning equipment: scale and other deposits cannot be completely removed, acid will corrode equipment and form holes, and residual acid Secondary corrosion or under-scaling corrosion on the material will eventually lead to equipment replacement. In addition, the cleaning waste liquid is toxic and requires a lot of money for wastewater treatment
