Оптимальная мощность теплового насоса в комбинированных системах теплоснабжения для южного региона Украины

Abstract

Рассмотрены проблемы внедрения тепловых насосов в существующие системы теплоснабжения. Указаны факторы, влияющие на эффективность использования тепла наружного воздуха тепловыми насосами. Рассмотрены ограничения использования одноступенчатых тепловых насосов в существующих системах отопления. Приведены результаты сравнительного расчета технико- экономических показателей использования двух типов тепловых насосов.

Due to the abrupt rise in prices for energy carriers the population shows a great interest in the integration of alternative heat sources into the heat supply systems of the buildings. One of the most efficient solutions is considered to be the placement of the thermal pump in parallel with the gas boiler. In this case it is necessary to take into consideration the factors that influence the heat pump operation efficiency in the entire heat supply system. At the moment we are facing the problem of the integration of renewable heat sources in heat supply systems without taking into consideration the operation modes of the heating system. This circumstance results in the degradation of microclimate parameters in the room, and in addition disputes and conflicts with the mounting organization arise. This paper gives consideration to the problem of the introduction of thermal pumps into available heat supply systems. The factors that affect the efficiency of the use of the outdoor air by thermal pumps integrated into the available heat supply system have been given. Consideration is also given to the limitations of the use of one-stage thermal pumps for available heating systems. The data of the comparative computation of technical and economic indices of the use of two types of thermal pumps with and/or without gas boiler have been provided.
