Air - cooled type cold water machine is through the wind turbine and air exchange heat of a refrigeration equipment, is currently the industry more commonly used models. Air cooled box type water cooler is a box sealed structure, the power is not large, so most of the use of scroll compressor. Scroll compressor is developed in the eighties of the 20th century new type of positive displacement compressors, it with its high efficiency, small size, light weight, low noise, simple structure and operation and stable characteristics, is widely used in air conditioning and refrigeration unit.
In fact, the scroll compressor is not only applied to our air-cooled box type chiller, for the box sealed structure of the water cooled box type cold water machine, as well as the same is the same as the cold water. Our common scroll compressor brand Sanyo of Japan, the United States Copeland, France maneurop etc., which maneurop mostly low temperature compressor, the temperature is below 0 DEG C.
So what are the characteristics of the scroll compressor?
1, the change of torque is small, the vibration is small;
2, high sealing requirements, the sealing mechanism is complex;
3, using the gas supporting mechanism, allowing liquid compression;
4, no suction, exhaust valve, high efficiency, high reliability, low noise;
5, the pressure difference between the two adjacent chambers is small, and the leakage of the gas is less;
6, there is no clearance volume, so there is no reduction in the gas transmission coefficient of the expansion process;
7. The machining accuracy of the vortex line is very high, and the special precision machining equipment must be used;
8, the cavity of the casing for the exhaust chamber, reducing the air suction preheating, improve the gas transmission coefficient of the compressor;
Above is the characteristics of the chiller heart -- scroll refrigeration compressor, more other types of compressor characteristics and relevant information, please continue to attention East Star Refrigeration yo, we will from time to time share some cold water machine information.
