The Initial Requirements for the Heat Exchanger for Gathering Phase Transition Energy

Abstract

Production of heat power equipment and provision of agricultural production facilities with it is less than 40 percent, so it is important to conduct research on the development of domestic heat exchange equipment. (Research purpose) The research purpose is in developing the initial requirements for the heat exchanger of an experimental installation in order to gather the energy of the water-ice phase transition for its manufacture. (Materials and methods) Authors conduct patent search on the websites of the World Intellectual Property Organization, Rospatent, Google patents, the European Patent Office and the Eurasian Patent Organization. The article presents drawings using the COMPASS-3D V17 graphic editor. (Results and discussion) The article presents an energy-saving system for maintaining the microclimate of an agricultural facility using a heat pump. It was found that the thermal and physical parameters of the coolant (freezing point, thermal conductivity, solubility of salt, density) as water and salt solutions of various concentrations, as well as electrical and physical parameters (permittivity, tangent of the dielectric loss angle, electrical conductivity, temperature coefficient of electrical conductivity) change during external electrophysical treatment (exposure to an electric field, including electric freezing), magnetic field (including alternating magnetic field in the ultrahigh frequency range, low-frequency magnetic field, weak infra-low frequency magnetic field). (Conclusions) The energy-saving, eco-friendly heat exchange equipment with a heat pump unit is designed to maintain the microclimate of agricultural facilities. The article presents the initial requirements for the heat exchanger of the experimental installation for obtaining the energy of the water-ice phase transition, which will allow producing an experimental sample. Authors have developed a scheme for a heat exchanger of an experimental sample of heat exchange equipment with a heat pump unit for gathering energy of the water-ice phase transition.
