On the Use of Heat Pumps

The problems of energy saving and environmental friendliness in the issues of heat supply, hot water supply and energy-intensive industrial production are constantly in the center of attention and research. The relevance of such research is caused by the need to reduce fuel consumption, reduce harmful emissions from fuel combustion, and reduce thermal pollution of the atmosphere. Heat pumps are devices that operate on a reverse cycle, i.e. heat is transferred from less heated bodies to more heated ones, and the heat pump requires an external energy source. In recent years, heat pumps have been increasingly used. In many technological processes there is incomplete utilization of primary energy, such unused energy refers to secondary energy resources. In the production of silicate bricks the main technological process is autoclaving, which uses saturated steam of high parameters. The steam condensate can be used to operate a heat pump. Thus, the use of waste heat carrier as a low-potential heat source contributes to the rational use of secondary energy resources and the development of energy-saving technologies. Heat supply by means of heat pumps represents modern, priority environmentally friendly technologies.
