AIR COOLED CONDENSER is a high-temperature and high-pressure gas discharged from a new refrigeration compressor. The heat of the refrigerant is transferred to the cooling medium (water or air), and it is condensed into a medium-temperature high-pressure liquid. Heat exchange equipment. According to the different cooling medium and cooling method, the condenser can be divided into three types: water-cooled condenser, air-cooled condenser and evaporator condenser.


Among them, water-cooled condensers are further divided into vertical shell and tube condensers, horizontal shell and tube condensers and casing condensers. The cold condenser is just a heat exchanger. After the compressor pumps the superheated vapor of the refrigerant to the condenser, it is transmitted to the outside through the condenser. The evaporator is connected to the condenser through a capillary tube. When the liquid refrigerant is ejected to the evaporator, it vaporizes and absorbs the heat of the evaporator, so that the evaporator cools and realizes refrigeration, and the gas refrigerant turns into a hot gas at this time. Pumping to the AIR COOLED CONDENSER dissipates the heat into the air, so as to realize the cycle. To put it simply, it is the process of liquid turning into gas and gas and then turning into liquid. Since vaporization needs to absorb heat, liquefaction needs to dissipate heat to achieve condensation.
It has applications in many industries. It is better to say that many AIR COOLED CONDENSERs are used in power plants to condense the steam discharged from turbines; in refrigeration plants, condensers are used to condense refrigeration vapors such as ammonia and freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors. In the distillation process, the tube-and-tube condenser that converts vapor into liquid is called a condenser. All condensers operate by removing heat from the gas or vapor. The shells of water-cooled condensers and shell-and-tube condensers are normally hot in the upper half and warm in the lower half. Due to the lack of refrigerant quantity, its entire shell is not too hot under abnormal conditions. The other situation is just the opposite, the whole case is very hot, mainly because of insufficient cooling water or poor heat dissipation. Under normal circumstances, the outer surface of the casing of the casing condenser is very hot, the reason is that the amount of cooling water is too small or the heat dissipation effect is poor; the other is that the outer surface of the entire casing is not too hot, which is also due to the insufficient amount of refrigerant. The normal condition of the temperature of the condenser is that the first half of the heat pipe is very hot, and its temperature has a slow and gradual decrease in equilibrium. Compared with the first half, the thermal sensitivity of the second half of the heat pipe is greatly reduced, because the refrigerant in the second half of the pipe has gradually liquefied and has reached the condensation temperature and subcooling temperature. When an abnormal situation occurs, one is that the first half is not too hot, and the second half is close to normal temperature. The reason is that the compressor absorbs wet vapor refrigerant or the amount of refrigerant is insufficient. The other is that the whole AIR COOLED CONDENSER is very hot, the reason is that the amount of refrigerant is too much or the amount of ventilation is small, or the ambient temperature is high.
