What are the different types of compressors used in air conditioners and refrigerators ? What are the main differences between them?
In airconditioners en koelkasten zijn de veelgebruikte compressoren voornamelijk van de volgende typen, elk met zijn eigen kenmerken in structuur, werkingsprincipe en toepassingsscenario's:
Reciprocating Compressor
Working Principle: Compress the gas by reciprocating motion of the piston in the cylinder. The gas is sucked into the cylinder and compressed by the movement of the piston.
Features: Simple structure, easy maintenance, suitable for small and medium-sized refrigeration systems.
Application: Widely used in household refrigerators and air conditioners.
Scroll Compressor
Working Principle: Compress the gas by the relative motion of two scrolls. One scroll is fixed, the other scroll rotates on it, and the gas is compressed between the scrolls.
Features: Smooth operation, low noise, high energy efficiency, compact structure and low failure rate.
Application: Commonly used in commercial and household air conditioners and some high-efficiency refrigerators.
Screw Compressor
Working Principle: Compress the gas by the interaction of two screws. The gas is gradually compressed in the space between the screws.
Features: Suitable for large-scale refrigeration systems, high efficiency, can withstand high loads, and suitable for continuous operation.
Applications: Widely used in industrial refrigeration and central air-conditioning systems.
Centrifugal Compressor
Working Principle: The gas is accelerated and converted into pressure through a high-speed rotating impeller. The gas is accelerated in the impeller, and then the kinetic energy is converted into pressure energy through the diffuser.
Features: Suitable for large-scale refrigeration systems, high efficiency, low noise, suitable for high flow and high pressure occasions.
Applications: Common in large central air-conditioning and industrial cooling systems.
Rotary Compressor
Working Principle: The gas is compressed in the cylinder using a rotating part (usually one or more rotors).
Features: Compact structure, smooth operation, low noise, suitable for small refrigeration equipment.
Applications: Commonly used in household air conditioners and small refrigerators.
Main Differences
Structuur en werkingsprincipe: verschillende soorten compressoren gebruiken verschillende mechanische principes, zoals het zuerkantige type zuigerbeweging, terwijl vortex en schroeftypen rotatiebeweging gebruiken.
Efficiëntie en energieverbruik: scroll- en centrifugaalcompressoren zijn over het algemeen efficiënter dan zuigercompressoren en zijn geschikt voor hoge belastingen en langdurige werking.
Toepasselijke scenario's: zuiger- en roterende compressoren zijn geschikt voor kleine apparatuur, terwijl schroef- en centrifugaalcompressoren meer geschikt zijn voor grootschalige koelbehoeften.
Ruis en onderhoud: Scroll- en roterende compressoren zijn over het algemeen stiller en vereisen relatief minder onderhoud, terwijl zuigercompressoren mogelijk frequenter onderhoud vereisen.
