| Abstract [eng] |
Compressor’s efficiency consists of several factors, which are interconnected and have different influence. The biggest amount of energy is used for vapour compression. This part also influences other components of energy consumption – losses for friction and losses in the proc-esses of suction and discharge of vapour (indicated losses). The sum of the three components of energy consumption can be determined experimentally, but it is difficult to dis-tinguish them. This article presents parametric analysis of compressor. Friction losses were calculated and deter-mined experimentally. Energy consumption for vapour compression was determined by the means of mathemati-cal modelling and also calculated according to standard equations. Methods for estimation of indicated losses and their comparative analysis are also presented. The article shows that friction losses can be determined through mathematical modelling with reasonable accuracy. |
