Description

technical field

[0001] The invention relates to a cooling and heat metering device; more specifically, the invention relates to an intelligent cooling and heat metering device with high-precision electric dynamic flow balance function applied to the water system of the air conditioner end (fan coil unit). Background technique

[0002] In a large number of civil buildings, the energy consumption of the HVAC system accounts for about 65% of the total energy consumption of the building. How to implement energy-saving, environmentally friendly, efficient and natural central air-conditioning technology has increasingly attracted people's attention. In order to meet the needs of sustainable development, it is necessary to maintain the coordination and consistency of the overall technology in the automatic control of central air conditioning, the measurement of cold and heat, and the balance of hydraulic pipe network.

[0003] At present, the known principles for central air-condit...
