Heat exchange district heating system of high-rise buildings

Abstract

The invention discloses a heat exchange district heating system of high-rise buildings. The system mainly consists of a plate heat exchanger, an expansion water tank, a circulating pump, a direct connecting booster variable-frequency pump, a control cabinet, a heat supply low district and a heat supply high district, wherein the plate heat exchanger is respectively connected with a primary water supply pipe and a primary water return pipe, and is also respectively connected with a low-district heat supply water pipe and a low-district heat supply water return pipe; the low-district heat supply water pipe and the low-district heat supply water return pipe are respectively connected with a high-district heat supply water pipe, a high-district heat supply water return pipe and the heat supply high district; and the direct connecting booster variable-frequency pump is mounted on the high-district heat supply water supply pipe. The system realizes the district heating control and the energy conservation of the heat supply low district and the heat supply high district of the high-rise buildings, reasonably uses the plate heat exchanger, the circulating pump, a water replenishment variable-frequency pump and the like to largely save the investment and the floor, and has the advantages of complete system configurations, high intelligent degree, convenience for installation and management and excellent practical value and promotion prospect.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a high-rise building heat exchange district heating system. Background technique [0002] With the development of building technology and the improvement of livability, district heating systems in high-rise buildings are becoming more and more common. At present, the district heating of high-rise buildings on the market is often conducted separately by setting up two or more sets of heat exchange units in heat exchange stations, and each heat exchange unit includes heat exchangers, circulation pumps, water supply pumps, water supply tanks, etc. Supporting facilities, which not only increases the floor area of ​​the heat exchange station, but also requires high investment and troublesome management and maintenance. Contents of the invention [0003] The object of the present invention is to provide a high-rise building heat exchange district heating system with low investment, ...
