Linear compressor
A linear compressor is a gas compressor where the piston moves along a linear track to compress to minimize energy loss during conversion.
History
A number of patents for linear compressors powered by free-piston engines were issued in the 20th century, including:
- To Brown, Boveri & Cie, GB191215963, published 1913-10-08[1]
- To Hugo Junkers, CA245708, published 1924-12-30[2]
- To Raúl Pateras Pescara, US1615133, published 1927-01-18[3]
The first market introduction of a linear compressor to compress refrigerant in a refrigerator was in 2001.[4]
Valved linear compressor
The single piston linear compressor uses dynamic counterbalancing, where an auxiliary movable mass is flexibly attached to a movable piston assembly and to the stationary compressor casing using auxiliary mechanical springs with zero vibration export at minimum electrical power and current consumed by the motor.[5] It is used in cryogenics.[6]
Linear compressors are used in LG and Kenmore refrigerators. Compressors of this type have less noise, and are more energy efficient than conventional refrigerator compressors. [7]
