Description

technical field

[0001] The invention relates to the technical field of heating system signal processing, in particular to an analog signal output circuit of a central air-conditioning zone controller. Background technique

[0002] Hydraulic imbalance is the most common problem in building HVAC water systems. Due to hydraulic imbalance, the flow distribution of the system is unreasonable, with excess flow in some areas and insufficient flow in some areas, resulting in the situation that some areas are not hot in winter and not cold in summer, and the system transports cold and heat unreasonably, resulting in energy waste. Or in order to solve this problem, improve the water pump head, but still can produce heat (cold) uneven and bigger electric energy waste. Therefore, the corresponding regulating valve must be used to adjust the flow distribution of the system.

[0003] Although some general-purpose valves such as globe valves and ball valves also have a certain adjustment...
