JUSTIFICATION OF THE PARAMETERS OF A COMBINED COOLING AND DRYING CHAMBER WITH A SOLAR AIR COLLECTOR AND A HEAT PUMP UDC:662 997. 631.344
Abstract
Large-scale research work is being carried out around the world aimed at developing technological schemes for combined refrigeration and drying chambers based on solar air collectors and heat pumps designed for drying, cooling and storing agricultural products. In this direction, in particular, priority is given to scientific research on optimizing the thermal parameters of technologies and systems for drying, cooling and storing agricultural products based on solar energy, studying heat and mass transfer processes, using solar air collectors and heat pumps to improve the energy efficiency of installations used for drying, cooling and storage of agricultural products. At the same time, an urgent task at present is to increase the energy efficiency of chambers designed for drying, cooling and storing agricultural products, to develop combined refrigeration and drying chambers with a solar air collector and a heat pump, as well as scientific substantiation of their thermal parameters.
Calculation of the temperature regime and thermal efficiency of the solar air collector was carried out using the following method. by the total radiation incident on the surface of the solar air collector, the useful heat received by the air in the solar air collector and the total heat loss from the solar air collector.
A thermal diagram of a combined cooling-drying chamber based on a solar air collector and heat pump devices has been developed, on the basis of which a technological diagram of the device has been developed
