Air Cooled Screw Chiller Common Fault Analysis
- Jun 30, 2017 -

Air Cooled Screw Chiller How to improve the service life of screw chillers and reduce the failure rate of screw chillers This problem has been plagued by a lot of friends, Air Cooled Screw Chiller but also friends are very much like to understand the relevant knowledge module, and to solve this problem, you must have a more comprehensive understanding of the screw chiller, only master the knowledge of mechanical equipment and Understand its performance, then the problem is naturally facing the solution, today for everyone to explain in detail the screw chillers classification, principles and applications, common fault analysis, selection points and troubleshooting, Air Cooled Screw Chiller all-round solution to everyone's doubts.

According to the air conditioning function, the refrigerant is different, the condensation way, the seal structure of the compressor, the structure of the evaporator, Air Cooled Screw Chiller the screw refrigeration compressor, can do six different categories:

(A), according to air conditioning function is divided into single cold type and heat pump type.

(B), according to the use of different refrigerant divided into R 134 a and R 22 two.

(C), according to its condensing method is divided into water-cooled screw chillers and air-cooled screw chillers.

(D), according to the compressor seal structure is divided into open, semi-closed and fully enclosed.

(5), according to the structure of the evaporator is divided into ordinary and full liquid type.

(6), according to the screw chillers used in the screw refrigeration compressor to different classification. Screw-type refrigeration compressor is divided into two kinds of twin-screw and single screw. The twin screw refrigeration compressor has a pair of rotors of the helical teeth which are gripped and oppositely opposite to each other. And the single-screw refrigeration compressor has an outer cylindrical surface with six spiral grooves for the rotor screw. On the left and right sides of the butterfly, the planets are exactly the same with 11 racks. A detailed understanding of the screw chillers classification, Air Cooled Screw Chiller for the need to purchase screw chillers friends is undoubtedly a great help.

Screw-type chiller because of its key components - the compressor screw screw screw machine, the unit from the evaporator out of the state of the gas refrigerant; compressed by the compressor after compression, into a high temperature and high pressure state. Compressed gas refrigerant, Air Cooled Screw Chiller 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 a gaseous refrigerant. The gaseous refrigerant is reintroduced into the compressor via piping to start a new cycle. This is the four cycles of the refrigeration cycle. Air Cooled Screw Chiller It is also the main working principle of the screw chiller.

Screw chiller power and compared to the scroll is relatively large, Air Cooled Screw Chiller mainly used in central air conditioning systems or large industrial refrigeration.
