Abstract
The construction and residential sector are two of the most energy intensive sectors in the field. The development of new variations in the operation of heating systems can significantly reduce energy consumption. This is particularly true in regions where indoor air heating is required for more than half of the year. The use of the thermal potential of the exhaust air from ventilation and air conditioning systems makes it possible to reduce energy consumption for space heating and, accordingly, reduce the environmental burden on the environment. A study of the dynamic relationship between the heat of the exhaust air and the output efficiency when using a recuperation system was carried out using the software products OpenStudio, EES, and Excel. The operating modes of the heat pump as part of the ventilation system are modeled for two designs: with the heat recovery of the exhaust air and with the use of outside air as a low-potential source. The model has been verified based on the results of field measurements of air and refrigerant parameters at the experimental facility. Based on the verified model, it is planned to study the energy, economic and environmental performance of the system during the heating period in the climatic conditions of St. Petersburg.
