Working principle
After absorbing the heat of cooled objects in the evaporator, the liquid refrigerant is vaporized into steam with low temperature and low pressure, sucked in by the compressor. Then it is discharged into the condenser after being compressed into steam with high temperature and high pressure. In the condenser, it releases heat to the cooling medium (water or air), and it will be condensed into high-pressure liquid. After being throttled into refrigerant with low temperature and low pressure by the throttle valve, it enters the evaporator again for heat absorption and vaporization, so that the purpose of repetitive cooling is realized. Thus, one cooling cycle is completed after the refrigerant undergoes evaporation, compression, condensing and throttling, these four basic processes in the system. Material contact parts can be made from SS304, SS316L, titanium, Hastelloy, PTFE lined or other materials. Its inside wall is treated with electrolytic mirror polishing or mechanical polishing while the outside wall is made from SS304 full-welding structure to preserve heat, and the outside surface is treated with mirror polishing or matte polishing.

Main features
1.As the cooling flow is big and its speed is high, so the heat transfer coefficient is high, generally K= 600~700(kcal/m2h℃).
2.It takes small land area when installed vertically, and it can be installed outdoors.
3.The cooling water flows straight at a high speed. Therefore, the requirement for water quality is not very high, and common water can serve as the cooling water.
4.The water scale in the pipe can be easily removed, and it can be done without stopping the cooling system.
5.The temperature rise of the cooling water in the vertical condenser is generally 2~4℃, and the logarithmic mean temperature difference is generally 5~6℃, so water consumption is high. As the equipment is put in the air, the pipe will be easily corroded, but leakage will be easily found if it occurs.
