Design of a Heat Exchanger for Gathering Energy of the Water-Ice Phase Transition

Abstract

The heat exchanger for gathering energy of the water-ice phase transition belongs to refrigeration technology and can be used in agriculture, namely at the enterprises of the agro-industrial complex and in systems of thermal accumulators, as well as for heating industrial and infrastructure facilities. (Research purpose) The research purpose is in developing a heat exchanger scheme for gathering energy of the water-ice phase transition. (Materials and methods) Authors have identified analogues and a prototype and considered their shortcomings. (Results and discussion) It was found that the technical result is achieved in the heat exchanger for gathering energy of water-ice phase transition containing a tank, a pump, according to the utility model, equipped with evaporator, compressor, condenser, throttle valve, forming a closed loop, and a solar collector. The evaporator is designed as a silicone tube, located in a coil, on the surface of which ice is formed, and inside that circulates a refrigerant to transfer energy of water-ice phase transition. The article shows that the capacity is divided by a partition with insulating material, whose height does not reach upper edge, in two sections for water evaporator and ice collector, which are connected by a pipe with pump from the tank for collecting and melting the ice in the water tank with evaporator. A heater connected to a solar collector and installed in the container for collecting and melting ice. (Conclusions) The article presents the scheme of a heat exchanger for gathering energy of the water-ice phase transition, describes its structure and operating principle.
