Embodiment Construction

[0031] refer to figure 1 As shown, a multi-zone heating system according to an embodiment of the present invention is disclosed. The multi-zone heating system 100 includes: a thermoelectric unit 102, several heating sections 104, a signal conversion device 106, a monitoring device 108, an adjustment Quantity calculation means 110 and adjustment means 112.

[0032]Each of the heating sections 104 supplies heat to an area. Several heating sections communicate with the thermoelectric unit 102 . Each heating section includes a hot water supply line 140 and a cold water recovery line 142 . The hot water supply pipeline 140 and the cold water recovery pipeline 142 are controlled by a hot water valve 141 and a cold water valve 143 respectively. The hot water supply line 140 has a temperature sensor 144 and a first flow sensor 146 , and the cold water recovery line 142 has a second flow sensor 148 . The hot water valve 141 and the cold water valve 143 generate a hot valve opening ...

Abstract

The invention discloses a multi-zone heating system, which includes: a thermoelectric unit, several heating sections, a signal conversion device, a monitoring device, an adjustment amount calculation device and an adjustment device. The present invention also discloses a control method for a multi-zone heating system, which is applied to the above-mentioned multi-zone heating system. The method includes: a signal collection step, a signal conversion step, a calculation step, an adjustment amount calculation step and an adjustment step. By adopting the multi-zone heating system and the control method of the heating system of the present invention, the operation status of the heating system can be monitored in real time, and the problem of overload or unbalanced load can be prevented.

Description

technical field [0001] The invention relates to the control technology of a heating system, in particular to a multi-zone heating system and a control method thereof. Background technique [0002] Commonly used heating methods are distributed heating and centralized heating. Distributed heating at the user's site, due to the limitation of the heating scale, only small boilers with low parameters and low thermal efficiency can be used (the thermal efficiency is about 50%). However, heating by thermal power plants will form regional centralized heating. Due to the large scale of heating, large boilers with high parameters and high efficiency can be used (thermal efficiency is above 85%), thereby greatly improving energy utilization efficiency and saving fuel. [0003] Although thermal power plants have thermoelectric units composed of large boilers, in fact, the scale and power of thermoelectric units are still relatively small. When heating multiple areas, it is necessary t...
