Basic working principle of the heating system: the low-temperature heat medium is heated in the heat source, and after absorbing heat, the low-temperature heat medium is changed into a high-temperature heat medium (high-temperature water or steam), and the high-temperature heat medium is conveyed into a room through a pipeline, and heat is released through the heat dissipation equipment, so that the temperature in the room is increased. The heating system mainly has two connection modes of series connection and parallel connection between the radiators and pipelines, and the whole system of the series connection mode adopts a main conveying pipe, so that the material consumption is less, the construction cost is low, but the quantity of radiators capable of being connected in series is less, the temperature of a single radiator in the series connection mode can not be adjusted through a temperature control valve of the radiator, and when one radiator is turned off, the whole system is stopped, or a bypass valve needs to be opened, so that the heating system is inconvenient to use and troublesome to maintain; the parallel connection mode needs to be provided with two main pipelines which are respectively an inlet pipe and an outlet pipe, so that the number of pipelines is large, the manufacturing cost is high, the number of connected radiators is large, and the maintenance is convenient; it can be seen that there are significant disadvantages to both series and parallel connections, and there is a need for improvements to existing structures.
