Abstract

The invention relates to the technical field of heating and energy conservation and provides a centralized heating public building heat supply energy-saving control method. The method comprises the following steps of: calculating a thermal load required by a public building room in the current time period; calculating water supply quantity required by the public building room in an equivalent area of a building which meets the heating requirement in the current time period; calculating hydraulic power of each pipe section in a pipe network and the total pipe network, performing circulating pump and fan frequency variable control on a water supply main pipe by employing a quantity regulating mode, and performing valve opening control on a water supply branch; and controlling power of a heat source. According to the embodiment, the real-time thermal load required by the building is calculated according to the indoor and outdoor thermal disturbance, the heat waste is reduced, the hydraulic power of the distribution pipe network is reasonably calculated, the pipe section with a proper pipe diameter and a circulating pump with a proper lift are selected according to the calculation, the time and area control and on-demand heating of the thermal load can be realized, and the functions of supervising, calculating and controlling are truly integrated.

Description

technical field [0001] The invention belongs to the technical field of heating and energy saving, and in particular relates to a method for controlling heating and energy saving of centralized heating for public buildings. Background technique [0002] At present, most of the central heating systems of public buildings have great waste and unbalanced heat distribution. The main disadvantages are: the thermal load of the heat source design is too large, the pipe network is too thick; the system automation level is low, and the monitoring center only plays a low role. In the heating system with the boiler as the heat source, the operation of the boiler mainly depends on the experience of the boiler operator to adjust the operating parameters of the boiler. There is no scientific and reasonable basis to calculate the dynamic heat load and adjust the operating parameters of the boiler and pipe network accordingly. The heating capacity of the heating system of the heat exchange s...
