Central air conditioning screw machine works
central air conditioning
Refrigeration compressor is the heart of the system, whether it is air conditioning, cold storage, refrigeration processes, and chemical conditions must have a compressor to do to protect this important part!
Refrigeration compressor types and forms of many, according to the principle of volumetric type and speed can be divided into two types, which displacement is the most common.
How to compress the gas compressor is it?
Simple and that is by changing the volume of gas to complete the process of gas compression and transportation! Any power equipment needs to have a motivation to be successful completion of the compressor is the same; it needs a motor (motor) to drive.
Volume is divided into reciprocating compressor and rotary piston two.
1, reciprocating piston within the cylinder by the piston reciprocating movement to change the volume of gas work; piston compressor has a long history, the production technology is mature.
2, the rotary compressor including smear (slide film) rotary compressors, screw compressors, the majority of the current domestic production of air conditioners with rotary compressors; screw-type compressor is mainly used for large-scale refrigeration equipment, now Some shopping malls are also a lot of office buildings using screw-type compressors.
Cooling system mainly consists of several devices:
Compressor - Condenser - throttling device - evaporator
Its basic principle is this, the compressor will be compressed into a high-pressure saturated refrigerant gas (Freon or ammonia), the gaseous refrigerant in the condenser and then through condensation.
After cutting through the throttling device, pass into the evaporator, the cooling medium for cooling the heat required. For example, the evaporator connected to the building of each room, the snake tube evaporator heat exchanger will work with the air, and then blast the air conditioning blowing through the room air.
The snake tube evaporator refrigerant heat exchanger into a low-pressure steam back after the compressor, and then compressed by the compressor, so that recycling is complete refrigeration system.
Heating system is also generally this principle, just the opposite way.
Screw with the average central air conditioning central air conditioning is not much difference, but the use of a screw, screw, or rely on a number of root screw meshing with each other to form a volume of space changing the transmission fluid. According to the number of mutual engagement of the screw can be divided into single-screw, twin-screw pump, three screw pump, and so on. According to copies of the location of the screw can be divided into vertical or horizontal. Meshing twin-screw pump which pumps outside, there are pump, active pole, driven rods, gears and bearings and other components. Active rod and is driven a left hand thread rod, respectively, a right-handed thread.
