Abstract
In the paper, a thermodynamic analysis of an air conditioning system necessary to store a quantity of 500 kg of apricots at a temperature of 10°C and a humidity of 90% in a fruit warehouse was aimed at. The storage
facility is cooled by means of an air handling unit (AHU). The energetic and exergetic analysis was carried out on the air conditioning system that treats a mixture of fresh air and recirculated air for various fractions of fresh air ranging from 0 to 100%, thus being able to perform a finer analysis of the operation of the installation under different working conditions. Based on the exergy analysis, the exergy loss was estimated for each device, depending on their destination and operating mode. Numerical and graphical results are presented related to the necessary mass flow rates of the air, the refrigeration load, the necessary treatment and evolution of humid air in the system, as well as the exergy loss in the main components of the air conditioning system. This theoretical study was carried out to obtain quantitative information that will lead to a better understanding of the air conditioning irreversibility process and their distribution amongst the system component and minimizing them for optimal air conditioning cycle.
