Results of experimental development of a laboratory water distillation installation based on a heat pump and a photovoltaic panel

Modern technologies and the continuous rise in water consumption require efficient and environmentally friendly methods of its extraction. According to the energy development strategy of the Russian Federation until 2035, the use of alternative energy sources in industry is a priority task for production. The use of renewable resources to produce distilled water for the needs of enterprises is becoming increasingly important. The innovative technology of a laboratory installation, combining water distillation using a heat pump and a photovoltaic panel, allows not only to obtain purified water, but also to heat the coolant before chemical purification. To create a laboratory stand, it is necessary to study the operating principles of the installation, divide the device into units: the main stand and the vacuum distiller, then model a three-dimensional image of each part of the complex in the SolidWorks software package. Based on the obtained models, a functional diagram of the complex is developed to obtain a coolant of the given parameters, and an algorithm is compiled for predicting the temperature of the heated water in the heat pump. The obtained installation test results are processed, and compared with theoretical data from tables of refrigerant properties, and a conclusion is drawn. The technology for producing purified water is aimed at replacing imported technologies and using renewable energy sources. The development of technologies for producing clean water is a priority for the development of the Russian energy sector. The results obtained indicate the potential of the laboratory installation for use in various areas where a reliable and environmentally friendly supply of distilled water is required, for example, in coastal areas for industrial facilities or agricultural enterprises.
