Types of condenser with EVR3-038S solenoid valve for refrigeration:
The high temperature and high pressure Freon of the refrigeration system enters the condenser after exiting the compressor, releasing a large amount of heat to the cooling medium, and is cooled and liquefied. Then, the condenser can be divided into three types according to its cooling form: water-cooled, air-cooled, evaporative and shower.
1,Water-cooled:
In a water-cooled condenser, the heat released by the refrigerant is carried away by the cooling water. Cooling water can flow through once or it can be recycled. When using circulating water, a cooling tower or a cold water pool is required. The water-cooled condenser has a shell-and-tube type, a casing type, and an immersed type.
The condenser for the water-cooled chiller is usually a shell-and-tube condenser, and the outer casing is made of a steel pipe having a thickness of 5 mm or more, and is subjected to rust-proof treatment with a pressure resistance of 20 kg/cm 2 . The heat exchange tube adopts a high-efficiency and efficient seamless copper tube with a pressure resistance of 10 Kg/cm 2 . The two end covers are interchangeable to change the direction of the water connection pipe. The water pipe process has multiple circuits, and each condenser and the compressor capacity cooperate with each other. The total heat transfer coefficient should be able to tolerate 0.00005Kcal/h. square centimeter °C-1 fouling factor, the condenser water pressure drop does not exceed 6.5mAq, and the straight-through water pipe is easy to clean and maintain.
2,Air-cooled:
In an air-cooled condenser, the heat released by the refrigerant is carried away by the air. Its structural form is mainly composed of several sets of copper tubes. Due to the poor heat transfer performance of the air, ribs are usually added outside the copper tube to increase the heat transfer area on the air side, and a ventilator is used to accelerate the air flow. Force air convection to increase heat dissipation.
3,Evaporation and watering:
In this type of condenser, the refrigerant condenses in the tube, and the outside of the tube is simultaneously cooled by water and air.
