Experimental study of thermodynamic efficiency of the absorption refrigeration machine and heat pump complex
Annotation
The article presents and discusses the results of an experimental study of the energy efficiency for the complex of the absorption absorption-diffusion refrigeration machine and heat pump installation (ADR-HPI). The basic thermal characteristics of the main components of the complex: ADR, capacitor, evaporator, and HPI compressor with the use of (PB) R22 - the traditional working substance forbidden now as ozone-depleting one, and R407C as an alternative mixture composition. It is proved that the implementation of the proposed technical solutions provides the cooling coefficient of ADR to reach the values of 0.83 (with the traditional electric heating of its generator – no more than 0.3). The results of the exergy analysis confirm the high thermodynamic efficiency of the complex solution for the problems of individual heat and cold supply.
