Many friends may not know about air conditioning compressors, or they may not understand them very well. Don’t worry, we will give you a brief introduction below!
Air conditioning compressor:
1. Reciprocating piston refrigeration compressor: Relying on the reciprocating motion of the piston to change the working volume of the cylinder.
According to the external structure, it is divided into: ① Fully enclosed: the cooling capacity is less than 60KW, mostly used in air conditioners and small refrigeration equipment.
The drive motor and moving parts are enclosed in the same space, with compact structure, good sealing and low noise. But the power is small and difficult to maintain.
Common brands for decoration: French-American Brazilian Taican, French-American Youle, American Copeland_Bristol, Danish Danfoss, Italian Embrac_Electrolux, Japanese Hitachi_Panasonic_Toshiba_Sanyo, Mitsubishi_DAKIN, Korean LG, China Chunlan, etc.
② Semi-closed: cooling capacity 60~600KW, can be used in various air conditioning and refrigeration equipment.
The crankcase body and the motor casing jointly form a closed space. It has stable operation and long life, large refrigeration capacity, can be used in a variety of working conditions, and can be repaired, but the noise is slightly higher. It is divided into single-stage compression type (conventional type, butterfly valve type, unloading type, connected type) and two-stage compression type.
Common brands: Virtue Copeland, Debizer_Bock_Grasso, Italy Fujiho_Lefukang, Japan Mitsubishi_Hitachi_Sanyo, China Taizhou Xuemei_Dalian Bingshan_Nanjing Wuzhou, etc.
③The open-type compressor and the motor are two devices connected externally. The structure is complex and heavy, and the operation is unstable. It is almost eliminated.
2. Rotary refrigeration compressor: The working volume of the cylinder is changed by the rotation of the rotary body.
Classification based on internal structure: ①Rolling rotor type: cooling capacity 8~12KW, mostly used in small air conditioners and refrigeration equipment.
It is fully enclosed, with compact structure, good sealing and low noise. But the power is small and difficult to maintain.
Common brands: Japan's Mitsubishi_Hitachi_Panasonic_Sanyo_Toshiba, China's Qing'an_Huangshi Dongbei, etc.
②Scroll type: cooling capacity 8~150KW, can be used in various air conditioning and refrigeration equipment. It is fully enclosed, with simple and compact structure, high working performance, good sealing and low noise, making it the leading model in the future.
Common brands: Virtue Copeland, French American Youle, Japan's Hitachi_Panasonic_Daikin_Sanyo, China Chunlan, etc.
③Screw type: cooling capacity 100~1200KW, can be used in large and medium-sized air conditioning and refrigeration equipment.
It is semi-enclosed, with compact structure, high working performance, large refrigeration capacity and stepless adjustment, but the lubricating oil system is complex and the noise is high.
It is divided into single and twin screw types.
Common brands: Debizer_Grasso, Italy Fujiho_Lefconn_Doling, Japan Hitachi_Daikin_Mitsubishi Heavy Industries_Kobelco, South Korea, foreign countries, Taiwan Fusheng_Hanbell, Jialing, Chongqing, China_Bingshan, Dalian, etc.
3. Centrifugal refrigeration compressor: relies on centrifugal force to continuously compress the inhaled gas.
The maximum cooling capacity can reach 30,000KW, which is used in large-scale air conditioning and refrigeration equipment. Stable operation, high performance, long life, large cooling capacity, and stepless adjustment.
Common brands: TRANE_CARRIER_YORK and MCQUAY, Japan's MITSUBISHI_HITACHI and EBARA, Switzerland's SULZER, Korean and Chinese manufacturers, etc.
The above is the relevant knowledge about air conditioning compressors that we have introduced to you. We hope it can be helpful to you.
