Abstract

The invention provides a heat collection efficiency test platform for a trough type solar heat collection system. The heat collection efficiency test platform comprises a working medium storage tank, a circulating pump, a heat collection loop, a stop valve, a regulating valve, a pressure stabilizing valve, a safety valve, a temperature measuring point, a pressure measuring point and a liquid level measuring point, wherein a temperature measuring point, a pressure measuring point and a liquid level measuring point are arranged on the working medium storage tank; the circulating pump is used for pumping the working medium in the working medium storage tank into the heat collection loop, and the working medium absorbs heat in the heat collection loop and flows into the working medium storage tank through the pressure stabilizing valve; by arranging the nitrogen pressure stabilizing system and the electric heating system, the heat exchange efficiency of the heat collector with different working media can be tested, the heat collection efficiency of the groove type heat collection system with water, heat conduction oil and high-temperature fused salt as the working media can be evaluated, and the problem that in the prior art, the heat exchange efficiency of the groove type heat collection system is influenced is solved. And the thermodynamic system test efficiency is low.

Description

technical field [0001] The present application relates to the technical field of performance testing of solar energy concentrating and heat collecting devices, and in particular, to a heat collecting efficiency test platform of a trough solar heat collecting system. Background technique [0002] As one of the most mature solar thermal utilization equipment, trough collectors are widely used in solar thermal power stations, supplying industrial hot water / steam and other fields. The quality of the trough collector's heat collection efficiency determines its solar energy utilization efficiency, so it is necessary to design a special system to evaluate its heat collection efficiency. [0003] At present, the general trough heat collecting system test platform mainly calculates the energy input by the sun into the heat collecting circuit based on the measurement of the direct radiation intensity combined with the heat collecting area of ​​the circuit and the incident angle. The ...
