Study of the Compressor which has Two Compressing Units in One Case

Abstract

The 2in1 type scroll compressor has been developed to cope with needs for mounting it in multisystem air conditioners for buildings,in which two scroll compressor units of different capacities are housed in a casing and one unit is controlled by the inverter. The development of the 2inl type scroll compressor brought about the following merits : 1)Having a variable capacity range of 2.9 KW to 29 KW,the air-conditioners can apply to various loading conditions including multi-system air conditioners for buildings. 2) The wider capacity range results in a higher efficiency and realized the multi-system air conditioners in higher efficiencies. 3) Reliability of the new system became satisfactory for the cycle of long piping and high refrigerant charge.
