The invention discloses a control method and a control device for a centralized heat exchange system. The heat exchange system comprises a heat exchanger, an adjusting valve and a main pipe valve, wherein the heat exchanger is connected with the adjusting valve; and the adjusting valve is connected with the main pipe valve. The control method comprises the steps of obtaining the water temperature of a water outlet of the heat exchanger, obtaining the target opening degree of the adjusting valve according to the water temperature and the preset temperature, and adjusting the adjusting valve if the target opening degree of the adjusting valve is within the preset range; and if the target opening degree of the adjusting valve exceeds the preset range, adjusting the main pipe valve. The target opening degree needing to be adjusted of the adjusting valve is detected, and the adjusting valve or the main pipe valve is selected to be adjusted according to the range of the target opening degree, so that the opening degree of the adjusting valve is prevented from exceeding a linear adjusting area, and the adjusting precision and the adjusting effect are improved.
Description
Technical field [0001] The present application relates to the technical field of heat exchange control, and more particularly to a control method and control device for a centralized heat exchange system. Background technique [0002] The heat exchange station is a device for the hot and hot station and the user end in a centralized cooling / heating system for allocation, control, and metering cold heat. In order to ensure the safety of the system, the heat transfer equipment (such as a plate heat exchanger) is generally transmitted, and the heat exchange device is connected to the heat and heat station to connect the heat transfer station to the side tube network, and the pipe network is connected to the secondary side pipe network. . During use, the change in user load can result in changes in the flow and temperature of the secondary side of the heat exchanger. In the adjustment method in the relevant technique, the opening degree of the valve can be automatically adjusted ac...
