Central heating is a relatively environmentally friendly, energy-saving HVAC solution suitable for China's national conditions, and it is currently the most important heating mode in China. With the continuous improvement of people's pursuit of the quality of life, the concern about the environment they live in, and the continuous strengthening of environmental protection awareness, environmental pollution and energy crisis are always in front of us. How to make the existing central heating system more efficient and energy-saving is the focus of every heating company dedicated to improving the residential environment of residents and having a sense of social responsibility.

The first station or relay pressure isolation station is mainly used for pressure isolation through heat exchangers, while ensuring the minimum temperature drop, which is one of the key points in the entire energy saving and consumption reduction system. The high temperature and high pressure hot water from the heat source plant is heated by a plate heat exchanger and used as the heat source of the secondary heat exchange station to realize the concept of high temperature and high pressure transmission and low temperature and low pressure use.
