Monitoring and simulation of parabolic trough collector powered vapor absorption refrigeration system for rural cold storage

India is one of the largest contributors to the world?s agricultural products. The majority of people?s livelihood in India depends on agriculture and its allied sectors. According to an economics survey in the agricultural year of 2019-2020, India is estimated to have produced around 292 million tonnes of food grain. The share of agriculture in India?s GDP is 19.9%. Even though India is an active participant in global agricultural trade, the total agricultural product export is only 2.5%. Agricultural produce is easily perishable and the quality gets affected which will then affect their market value. To meet the future food demands, agricultural produce must be able to store for a longer amount of time for round the year availability. The traditional food storage practices cannot satisfy that condition. These perishables need a proper cold supply chain to increase the shelf life. In this paper performance of a Parabolic Trough Collector Integrated Vapor Absorption Refrigeration system was developed and studied. Renewable integrated cold storage would open door to the sustainable energy future.

Vapor Absorption Refrigeration

In this paper, an inverse problem is solved for estimating parameters of a steam-driven water–lithium bromide (LiBr) vapor absorption refrigeration system (VARS) using a differential evolution (DE)-based inverse approach. Initially, a forward model simulates the steady-state performance of the VARS at various operating temperatures and evaporator cooling loads (CLs). A DE-based inverse analysis is then performed to estimate the operating parameters taking VARS coefficient of performance (COP), CL, total irreversibility, and exergy efficiency as objective functions (one objective function at a time). DE-based inverse technique estimates the parameters within a very short period of elapsed time. Over 50 and 100 numbers of generations are sufficient for retrieval of COP and exergy efficiency, respectively, while it requires 150 generations for total irreversibility and CL. The study reveals that multiple combinations of parameters within a given range satisfy a particular objective function which serves as design guidelines in selecting appropriate operating parameters.
