Problems solved by technology

Later, the Beijing Testing Center carried out technical transformation on the system, which made the test system have a certain pressure-bearing capacity, but the open system itself cannot withstand pressure, so that its maximum test temperature can only reach 105 ° C, which is obviously difficult to meet the current heat collection requirements. The rapid development of collector research, especially the development of medium temperature collectors that are gradually applied in the industrial field
[0005] Although my country is currently supported by international funds and technologies in the field of solar energy detection, the core technology is still mastered by developed countries and is in a non-free state. The principle and specific structure of its detection system are still unknown
As far as the current situation is concerned, the specific technical solutions of my country's existing solar collector test systems have not been made public, but only partially disclosed its principles

Abstract

The invention discloses a test system and a test method for a solar heat collector. The test system and the test method adopt a closed cycle system to solve the problem that the test temperature of the prior test system is low, adopt multi-aspect data acquisition and control, and are easy to control and acquire test parameters.

Description

(1) Technical field [0001] The invention relates to a solar heat collector test system and a test method, which belong to the technical field of heat collection performance detection of solar heat collectors. The solar heat collector test system includes a circulation system for circulating medium circulation and a Data acquisition system for detecting circulating medium parameters. (2) Background technology [0002] The national standard for solar collectors in my country was promulgated and implemented in 1998, and the detection of solar collectors was not fully carried out until the establishment of the National Solar Water Heater Quality Supervision and Inspection Center in Wuhan and Beijing from 2003 to 2005, but the test level is far from the international standard. High-level testing organizations such as Swiss SPF and German ITW still have a certain distance. [0003] The current situation of solar energy detection in my country is: Although due to the late start, th...
