Water Cooled Chiller Working Principle
- Jun 30, 2017 -

Screw-type chiller because of its key components - the compressor screw screw screw machine, Water Cooled Chiller 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. Water Cooled Chiller 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 a gaseous refrigerant. Water Cooled Chiller The gaseous refrigerant is reintroduced into the compressor via piping 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.

The twin screw refrigeration compressor is an energy adjustable fuel injection compressor. Its three processes of inhaling, compressing, and exhausting are achieved by the generation of periodic volumetric changes in the rotation of a pair of intermeshing yin and yang rotors in the body. Water Cooled Chiller Generally the male rotor is the active rotor, the female rotor is the driven rotor. Main components: double rotor, body, main bearing, shaft seal, balance piston and energy regulator. Capacity 15 ~ 100% stepless adjustment or two, three-stage adjustment, to take the hydraulic piston to reduce the load way. Conventional use: radial and axial are rolling bearings; open with oil separator, oil tank and oil pump; closed for the differential pressure oil lubrication, fuel injection, Water Cooled Chiller cooling and drive slide valve capacity adjustment of the piston movement. Inhalation process: the gas through the suction port, respectively, into the yin and yang rotor teeth volume. Compression process: the rotor rotation, the interdental volume between the cathode and cathode (V-type space), due to the intermeshing of the teeth, the volume gradually reduced, Water Cooled Chiller the gas is compressed. Exhaust process: compressed gas moved to the exhaust port to complete a working cycle.

Compression is achieved by the engagement of an active rotor and two star wheels. It is the suction, compression, exhaust three consecutive process is by the rotor, Water Cooled Chiller the star wheel rotation occurs when the cyclical volume changes to achieve. Rotor teeth for six, star wheel for the eleven teeth The main components for a rotor, two stars, the body, the main bearing, energy adjustment device. Capacity can be from 10% -100% stepless adjustment and three or four-stage adjustment. Inhalation process: the gas through the suction port into the rotor tooth groove. With the rotation of the rotor, the star wheel enters into the state of meshing with the rotor toothway, and the gas enters the compression chamber (the closed space formed by the rotor tooth surface, Water Cooled Chiller the casing cavity and the star wheel tooth surface). Compression process: With the rotor rotation, compression chamber volume continues to decrease, the gas with compression until the compression chamber front to the exhaust port. Exhaust process: the compression chamber front to the exhaust port after the exhaust, they complete a working cycle. As the star wheel is symmetrically arranged, the cycle is compressed twice every one revolution, and the displacement is twice the amount of the cycle exhaust.

In view of the use of screw chillers, Water Cooled Chiller friends will be more common fault problems such as high voltage failure, low voltage fault, Water Cooled Chiller low valve temperature fault, compressor overheating fault, communication failure, etc., but would like to effectively solve these fault problems or must First link under the screw-type chiller's main working principle, which is among the heavy cycle of the four processes, after the compressor adiabatic compression, into a high temperature and high pressure state. Compressed gas refrigerant, Water Cooled 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, Water Cooled Chiller 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.
