Heat storage and supply system and leakage detection method

Abstract

The invention provides a heat storage and supply system. The system comprises a heat source, a heat supply pipe network, a user and a heat accumulator, wherein the heat supply pipe network comprises awater supply pipe network and a backwater pipe network, hot water enters the user for heat supply through the water supply pipe network, and cold water after heat supply returns to the heat source through the backwater pipe network; the heat accumulator is arranged on a first pipeline, the user is arranged on a second pipeline, and the first pipeline is connected with the second pipeline in parallel; and the water supply pipe network and the backwater pipe network are respectively provided with a third valve and a fourth valve, and the third valve and the fourth valve are opened when the heatsource operates, and when the heat source stops running or the energy of the heat source is insufficient, the third valve and the fourth valve are closed, so that the heat accumulator becomes a new heat source, a new heat supply system is formed by the heat accumulator and the user, and heat is supplied to the user through the heat accumulator. Through the above arrangement, it is ensured that the heat accumulator can store heat, and heat supply under the condition of insufficient conditions is met.

Description

technical field [0001] The invention relates to a heat supply system, in particular to a heat supply system for intelligent heat storage. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, people's demand for domestic hot water and heating hot water is also increasing. According to statistical data, the proportion of my country's building energy consumption to the total social energy consumption is between 22% and 25%, of which about 40% is used for building heating. Consumption accounts for about 60% of building heating energy consumption. With the improvement of living standards, many newly built communities in the Yangtze River Basin have also begun to adopt central heating, and many cities are also planning large-scale central heating networks. It can be seen that there are more and more regions with central heating demand. In addition, with the rapid increase of building area, the demand for heatin...
