Problems solved by technology

However, the current specific heat calculation methods all use a linear relationship for calculation. When the specific heat changes between the two temperatures t1 and t2 before and after the calculation, the value of the shaded part in the figure is virtually missing.
Therefore, the final Q value is not accurate

Abstract

The invention provides a thermal energy measurement method of heat transfer oil, which uses a temperature sensor to collect the temperature t of the heat transfer oil in real time; uses an operation recorder to inquire in real time the specific heat capacity C(t) and density ρ(t) of the heat transfer oil corresponding to the collected temperature t The calculation recorder uses the formula Sm=ρ(t)×Sv to calculate in real time the mass flow rate Sm of the heat transfer oil corresponding to the collected temperature; then calculate the thermal energy q of the heat transfer oil from the temperature t=t1 to t=t2; Finally, the same time period is intercepted, and the heat energy of the heat transfer oil at the outlet is subtracted from the heat energy of the heat transfer oil at the inlet, which is the heat released by the fluid or the heat generated by the boiler. When calculating the heat energy of the heat transfer oil, the present invention adopts an integral calculation method to record the change of C(t) in real time, so as to approach the change curve of the specific heat more strictly, and the calculated heat transfer oil heat energy is more accurate.

Description

technical field [0001] The invention relates to a heat energy metering method of heat transfer oil, in particular to a real-time monitoring method for thermal efficiency of an industrial organic heat carrier boiler and a method for measuring energy consumption of heat transfer oil as a heat carrier. Background technique [0002] At present, the actual thermal efficiency of most industrial organic heat carrier boilers needs to be obtained after detection and calculation by personnel with professional knowledge using professional instruments. Moreover, in actual use, the heat energy generated by the heat transfer oil as the heat carrier is also due to other reasons such as the accuracy of the system equipped with measuring instruments, the mastery of the professional knowledge of the personnel, and other reasons, so that the energy-consuming enterprises cannot accurately grasp the actual energy consumption of the enterprise's production. [0003] At present, the thermal energy...
