Abstract

The invention discloses a balance adjusting method for heat storage and release of a heat supply network and a heat supply system, and belongs to the technical field of centralized heat supply. The heat supply system comprises a thermoelectric unit, a heat supply network initial station, a heat supply network circulating water pump, n heat stations, an electric adjusting valve, a temperature pressure flow measuring instrument, a temperature flow measuring instrument, a temperature measuring instrument and a flow measuring instrument, and n is larger than or equal to 2. The heat imbalance degree of the heat supply system is calculated in real time, and a bypass is arranged on the primary network side of the heat station to adjust the heat supply network water flow entering the heat station, so that the heat supply load balance of each heat station is ensured, the dynamic balance of heat supply network operation is achieved, the reliability of balance adjustment of the heat supply system is improved while the heat storage capacity of the heat supply system is brought into play, and high practical application value is achieved.

Description

technical field [0001] The invention relates to the technical field of centralized heating, in particular to a method for balancing heat storage and discharge in a heat network and a heating system. Background technique [0002] The central heating system is one of the city's infrastructure and one of the signs of the city's modernization level. At present, the central heating system generally has problems of hydraulic imbalance and thermal imbalance, resulting in different room temperature of heat users, which not only affects the quality of heat supply, but also brings losses to heat supply enterprises in some aspects. [0003] With the shutdown of highly polluting decentralized coal-fired heating boilers, combined heat and power, as one of the main ways of clean heating, has been continuously used as an important heat source to replace decentralized coal-fired heating boilers, which has also caused cogeneration The heating pipe network of the central heating system is be...
