Rotary compressors are ‘high pressure shell’ type compressors. The suction on these compressors is taken directly into the compression chamber. Gas compressed in the compression chamber is discharged into the compressor casing. It should be noted that from a cold start-up, high pressure shelltype compressors take longer to reach their normal operating pressure in the compressor shell. This is partly due to the larger volume of the compressor casing and partly as a result of refrigerant beingtrapped in the oil. Any refrigerant in the oil has to completely evaporate before condensing pressure canreach its operating level.
