Embodiment Construction

[0030] Specific embodiments of the present invention will be described in detail with reference to the above-mentioned drawings. Figure 1 ~ Figure 4 Combined with a fan coil cooling and heat intelligent metering device, it is composed of five parts: an intelligent meter 100, a connecting cable group 200, an electric dynamic flow balance valve 300, a return water temperature sensor 400, and a water supply temperature sensor 500.

[0031] Electric dynamic flow balance valve 300 as Figure 4 As shown, it includes an electric valve body 301 with a passage 309 inside; An automatic flow controller is set in the channel 309, that is, an automatic flow controller is set between the inlet and outlet of the channel 309. The automatic flow controller includes a flow control valve body 303 , the control valve body 303 is fixed inside the electric valve body 301 through screw connection or welding, and communicates with the channel 309 . The upper end of the bushing 305 communicates wit...

Abstract

The invention discloses a fan coiler cold and heat intelligent metering apparatus, which comprises an intelligent metering device, an interconnecting cable group, an electric dynamic flow holding valve(300), a backwater temperature sensor and a water supply temperature sensor.The electric dynamic flow holding valve(300), a backwater temperature sensor and a water supply temperature sensor are separately connected to an intelligent metering device by interconnecting cable group, while backwater temperature sensor is connected to electrical dynamic flow holding valve.

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...
