Experimental Investigation of Vapour Absorption Refrigeration Cycle for Automobile Cabin Cooling
Because the currently used Vapour Compression Refrigeration cycle (VCRC) for air conditioning in cars, uses compressor which leads to degradation of performance of engine. This can be replaced with vapour absorption refrigeration cycle (VARC). The above hypothesis was studied using Electrolux VARC setup installed in SKNCOE, Pune. The main motive behind experimentations was to check the feasibility of implementation of VARC in cars for cabin cooling. Since heat recovered from exhaust gases is utilized in VARC, it results in economical air conditioning. Implementations of this concept will after-effect into high energy conservation in tropical countries. Since the performance of any thermodynamic system is dependent on temperatures, variation in performance of VARC system with respect to various temperatures is studied. Along with the performance analysis, the paper focuses on the enlightening the practical approach of implementation of the above system into automobiles. When using this system, it was found that energy saving up to 10% could have been achieved based on experimental data of this system.
