Problems solved by technology
[0005] In the process of realizing the present invention, the inventor found that: in the existing flow verification system, the water tank / pool is usually open, and the heat loss is very large; at the same time, the difference between the flow verification system and the actual HVAC working conditions Often very large, when the heat meter verified by the flow verification system is applied to the actual HVAC working conditions, the flow measurement results often have large errors, so the energy loss and flow verification of the existing flow verification system are accurate. Sex needs to be further improved

Abstract
The invention relates to an energy-saving heat meter flow verification device and method, wherein the device includes: a water supply system, a closed circulation system and a standard meter calibration system; when the water supply valve of the water supply system is open The water in the tank is transported to the closed circulation system; the closed circulation system includes: circulation pump, stabilizing tank, standard meter, heat meter to be tested, switch valve, water temperature compensation unit and flow regulating valve, the water outlet of the circulating pump and the steady state The water inlet of the pressurized tank is connected, the water outlet of the pressurized tank is connected with the standard meter and the heat meter to be tested in series, and the switch valve, flow regulating valve and water temperature compensation unit are set in the closed circulation path of the closed circulation system; the standard meter The water container in the calibration system communicates with the closed circulation system through a commutator. The technical solution provided by the present invention can effectively reduce energy loss and improve the flow measurement accuracy of the heat meter to be tested in practical applications.
Description
technical field [0001] The invention relates to flow verification technology, in particular to an energy-saving heat meter flow verification device and method. Background technique [0002] A heat meter is an instrument that measures heat. The application range of heat meters in people's daily life and work is more and more extensive, such as heating in residents' homes, if the heat meters are used to measure and charge the heat energy actually used by users, it is a reasonable charging method for users . [0003] The heat meter's measurement of flow, temperature and heat energy calculation will have a great impact on the accuracy of heat energy measurement; Measurement accuracy, temperature measurement accuracy, and thermal energy calculation accuracy, etc.; therefore, heat meters usually undergo flow verification, temperature verification, and calculation method verification before leaving the factory or during maintenance. [0004] At present, the implementation method...
