Використання теплових насосів для утилізації техногенних повітряних джерел теплоти

Abstract

The thermodynamic analysis of the heat pump scheme of heat use of technogenic air emissions in the system of low-temperature heating is carried out. The condition of the analysis is the optimization of the system parameters on the basis of the obtained useful effect taking into account the energy costs for the drive of the heat pump compressor. Graphical dependences of the optimal degree of cooling of the air at the outlet of the heat pump evaporator on the temperature of the heat source and the calculated temperature in the low-temperature heating system are obtained. It is determined that when using this scheme at the stage of design of the system of heat pump heating it is possible to significantly reduce capital and operating costs. The use of obtained dependencies in the development of heat pump systems will ensure the maximum energy efficiency of their operation.
