working principle

 

For the traditional air-cooled, water-cooled condensers, evaporative condensers are more energy-efficient, more water-efficient, and widely used. The series of product specifications are complete, and the heat exchange capacity is large. It is particularly suitable for the application of refrigeration and heat transfer processes in medium and large-scale projects. . Compared with similar products, the heat exchange efficiency is high and the service life is long. In addition, the evaporative condenser uses advanced technologies such as thermodynamics and heat transfer engineering, and is an optimized combination of a cross-flow cooling tower and a conventional evaporative condenser. Widely used in food, chemical, pharmaceutical, beverage, dairy, coal mining and other industries.

The superheated refrigerant discharged from the compressor enters the condensing coil. The gaseous refrigerant in the coil exchanges heat with the spray water and air outside the coil, and gradually cools and condenses into a liquid state. The strong wind of the induced draft fan makes the spray water completely and evenly covered on the surface of the coil, and the water cherishes the wind and the heat exchange effect is significantly improved. After spray water and air absorb hot dust, the temperature rises, and some of the water changes from liquid to gaseous. A large amount of heat is taken by the enthalpy latent tropical heat. The water in the hot air is trapped by a high-efficiency dehydrator and enters the collection tank to reduce The consumption of water is then fed into the spray system by a circulating pump and the cycle continues. A floating ball valve is arranged in the water tank. When the water continuously churns the water in the water tank and the water level is too low, the float valve automatically opens the supplemental cooling water.

 

Features

 

1, save electricity

 

Since the condensing temperature of the evaporative condenser is determined by the wet bulb temperature, the wet bulb temperature is generally 6°C to 8°C lower than the dry bulb temperature. The unique design of the evaporative condenser takes full advantage of this characteristic. Therefore, the condensing temperature and pressure of the refrigeration system are reduced, the refrigeration capacity of the compressor is increased, and the power consumption is reduced, and the power of the water pump and the motor configured by the evaporative condenser is only about 40% of that of the water pump motor used in other water-cooled condensers. Practical applications, as long as the configuration is reasonable, properly selected, evaporative cooling than other types of condenser power consumption decreased by about 5%.

 

2, water saving

 

The evaporative condenser mainly uses the evaporation heat of the water to travel the condensation heat of the refrigerant. Evaporation of 1 litre of water can take away 670W of heat, and the water is cold and cold. The suspect device uses the heat of water to heat and absorb heat, and 1 litre of water only takes 5W to 6W of heat. The evaporatively-configured water eliminator has high-efficiency dewatering capacity and little water loss. It can be used in drought- and water-less areas.

 

3, improve system quality

 

The use of a evaporative cold refrigeration system results in a low condensing temperature, a corresponding decrease in the exhaust pressure, exhaust temperature, and lubricating oil temperature. The operating conditions of the compressor are improved, the service life is extended, and the compressor's trouble-free operation cycle is extended, increasing the number of systems. reliability.

 

4, easy to use

 

The company's evaporative cold inner tube group has a large heat exchange area. Before the ambient temperature drops to the freezing point, the circulating water system will be shut down and the water in the lower water tray will be released. Competition and dry operation will save more time and effort.

 

5, easy to install

 

The evaporative condenser integrates the cooling tower, the pool, and the water pump together, with less installation materials and shorter construction period, saving installation costs.

 

6, durable, highlight the quality

 

The whole shell is made of Baosteel galvanized steel sheet, which has been used for a long time. The tube group adopts the international 8163 fluid special steel tube. After the whole group is tested by 2.5MP, it is treated with antisepsis and anti-fouling.
