چکیده
Background. Currently, in the cycles of steam-ejector refrigeration machines (SERM) are used monoagent jet compressors, working body which is water. Despite their low efficiency, SERM have a number advantages over that usemechanical compressors: cost, ease manufacture and reliability. The use largely limited by inability these installations to reach temperatures below 0 °C. This limitation can be overcome applying fundamentally new steam compressioncycle using bioagent (water-freon) compressor (BAJC).Objective. purpose paper experimentally confirm operability machine operating on compression cycle compressor. Determine efficiency experimental andfind optimal geometric characteristics compressor.Methods. An stand was created study plant BAJC. e determined according developed method.Results. Experimental values cooling coefficient were obtained depending change ejection q maximum emax = 1,3 ÷ 1, 4 correspond those opt ≈опт 0, 25q 0,25, also achieves h ≈max 0,35 45 BAJC.Conclusions. unit has been confirmed. To expand temperature spectrum direction lowering boilingpoints evaporator (tboilt −≤кип 20 °C), it planned modernise laboratory bench aqueous salt solutions as coolant.

Optimisation of Refrigeration Compressor Controllers
Optimisation provides the means of raising or lowering the target suction pressure in a Honeywell Genus® pack controller. Suction pressure optimisation means that suction pressures are raised to the highest level allowed within defined evaporator performance limits. This provides optimum compressor energy consumption while ensuring that the refrigerated merchandise quality is maintained at the ...
