Abstract

The invention discloses a thermal performance test system of a solar water heater. The thermal performance test system comprises a pipeline system, a test rack and a full-automatic intelligent control system. The pipeline system comprises a constant-temperature water tank (1), a refrigeration system connected with the constant-temperature water tank (1), a self-circulation system positioned outside the constant-temperature water tank (1), and an electric heating device arranged at the bottom of the constant-temperature water tank; the pipeline system is connected with a thermal storage water tank (10) in a test rack system of the solar water heater; and the pipeline system, the constant-temperature water tank and a water storage water tank form a loop. The full-automatic intelligent control system realizes data acquisition, sequential logic control and real-time regulation and control of temperature and flow by adopting a programmable controller (PLC).

Description

technical field

[0001] The invention relates to a thermal performance testing device and an automatic control system of a solar water heater. Background technique

[0002] In recent years, China's solar water heater industry has developed rapidly. my country has become the world's largest producer of solar water heaters. Domestic companies have also set their sights on overseas markets. However, my country's testing standards are not yet in line with international standards. Chinese patent 2008102436679 discloses an automatic constant temperature test system for solar water heaters with mixed water drainage method. The system monitors and records various parameters in the test through data acquisition equipment, and uses secondary heating equipment to control the water temperature of the constant temperature water tank, which can meet the international standard IS09459-2 and the national standard GB / T19141-2003 at the same time. However, this test system also has the follow...
