Air Cooled Screw Chiller Process
- Sep 18, 2017 -

Air-cooled screw chiller because of its key components - the compressor used screw-type air-cooled screw chiller, the unit out of the evaporator by the state of the gas refrigerant; compressed by the compressor after compression, into a high temperature and high pressure state. Compressed gas refrigerant, in the condenser, isostatic cooling condensation, after condensation into liquid refrigerant, and then through the throttle valve to low pressure, into a gas-liquid mixture. Which low temperature and low pressure liquid refrigerant, in the evaporator to absorb the heat of cold matter, re-become gaseous refrigerant. The gaseous refrigerant is reintroduced into the compressor via the pipe to start a new cycle. This is the four cycles of the refrigeration cycle. It is also the main working principle of the screw chiller.


1, the use of international brands compressor, the new high efficiency spiral rotor compressor, compressor performance than the average 20% -30% higher, and access to Europe and the United States multi-national patent IS9001 international quality certification.

2, high efficiency 5: 6 patent asymmetric rotor tooth profile.

3, capacity control can be used four-stage (100% -75% -50% -25%) or three (100% -66% -33%) and no-stage control system.

4, the use of 11 bearings and a axial thrust balance drum combination design, a substantial increase in bearing life 2.5-3.5 times.

5, the use of high efficiency silicon steel special slot design, and equipped with internal and external design of the cooling channel, so that the compressor motor can play under any load the highest efficiency.

6, a unique built-in hydraulic system, no oil pump to ensure that the compressor to maintain the best lubrication effect Oil separator with double filter, filter effect is good, heat exchanger can play the maximum capacity.

7, high efficiency, low noise, low vibration.

8, a variety of refrigerants to choose from, in addition to R22 refrigerant, you can also use R134a, R407c and other environmentally friendly refrigerant.

9, the full range of compressor capacity (VI = 2.2 / 2.6 / 3.0 / 3.5) can be effectively avoided due to over-compression or compression caused by the additional energy consumption.

With the rapid development of economy, the continuous improvement of scientific and technological strength, our chiller manufacturing technology is also changing, and the gap between developed countries is gradually narrowing, but the main core components such as compressors or foreign joint ventures, Inadvertently increased business costs.

Modern society, the application of refrigeration equipment more and more widely, modern refrigeration equipment are used to cool the chiller, chiller market development prospects can be expected. The advanced state of the cold water machine is still some developed countries in the West. Their development trend is also combined with the reality of the country, and vigorously improve the chiller shape, and constantly improve the performance of chillers, chillers to achieve smaller, the effect of increased efficiency.

Experts point out that in the increasingly fierce market competition, chillers developed technology matures today, miniaturization, high performance chiller has become a new trend. At the same time, in order to meet the rapid development of industrial production, more personalized, more fit production of the actual product will continue to emerge
