Cold-heat source system flow testing device

Abstract

The invention discloses a cold-heat source system flow testing device, which comprises a tee joint, wherein a port A of the tee joint is used as a water inlet, a port B of the tee joint serves as a water outlet, a port C of the tee joint is connected with a test tube, a tube opening of the test tube is sealed through a flange, a net bag is arranged in the tee joint, the net bag is internally provided with a temperature probe and a flow sensor, and the temperature probe and the flow sensor are connected with a data acquisition module through a sensing line A and a sensing line B respectively. According to the invention, the temperature probe and the flow sensor are directly communicated with a water supply and return pipeline through the sensing lines, thereby realizing direct contact between the probe and a medium, and measuring the water supply and return temperature and flow of the ground source side and the user side.

Description

technical field [0001] The invention relates to a flow test device, more specifically, to a flow test device for a cold and heat source system. Background technique [0002] With the increasing development of industrial technology and the development and utilization of new energy, flow detection has become an important part of detection technology in the process of building energy-saving renovation. The flow can directly reflect the flow characteristics, working status and energy consumption of buildings. In the process of formulating energy-saving strategies and improving energy utilization, temperature, pressure and flow are the main influencing factors. Among them, the detection and consideration of temperature and pressure are very mature, but the monitoring and related analysis of flow are not perfect and accurate enough. Therefore, the importance of flow monitoring is even more prominent. In general, the flow monitoring will be measured directly or on the outer wall o...

In the process of formulating energy-saving strategies and improving energy utilization, temperature, pressure and flow are the main influencing factors. Among them, the detection and consideration of temperature and pressure are very mature, but the monitoring and related analysis of flow are not perfect and accurate enough. Therefore, the importance of flow monitoring is even more prominent

In general, the flow monitoring will be measured directly or on the outer wall of the pipeline, such as electromagnetic flowmeters and ultrasonic flowmeters, which are difficult to meet the stability of the production process, as well as high precision, low error, strong real-time performance, and the ability to achieve Remote concentration requirements
