Abstract

The use of low grade heat sources by heat pump plants in heat supply systems in developed European countries is considered. It is established that process waters, natural reservoirs, ventilation emissions of buildings, sea water, heat of refrigeration units, groundwater, flue gases of boilers and thermal power plants, wastewater, heat of solar energy batteries, geothermal heat are used as low grade heat sources for heat pump plants. It is shown that for heat pump plants of district heating systems in Ukraine it is most expedient to use the heat of: ventilation emissions of buildings connected to these systems, wastewater, soils and groundwater, air, flue gases of boilers and CHP, rivers, process water, emissions and discharges of industrial enterprises. Exhaust ventilation heat of supermarkets, shopping malls and subways will be used not for district heating systems, but for the own needs of these organizations. The use of the heat of soils and groundwater will not be widely used in district heating systems due to the density of urban buildings Keywords: low grade heat source, district heating systems, thermal energy, heat pump

区域供热系统中热泵设备的低品位热源概述

考虑了欧洲发达国家热泵厂在供热系统中使用低品位热源的问题。确定了工艺用水、天然水库、建筑物通风排放物、海水、制冷机组的热量、地下水、锅炉和热电厂的烟道气、废水、太阳能电池的热量、地热作为热泵厂的低品位热源。研究表明，对于乌克兰区域供热系统的热泵厂来说，使用与这些系统相连的建筑物的通风排放物、废水、土壤和地下水、空气、锅炉和热电联产的烟道气、河流、工艺用水、工业企业的排放物和排放物是最有利的。超市、商场和地铁的排风热量将不用于区域供热系统，而是用于这些组织的自身需求。关键词:低品位热源，区域供热系统，热能，热泵，土壤和地下水的热量，由于城市建筑的密度，在区域供热系统中不会得到广泛的应用
