3 Terms and definitions

For the purposes of this document, the terms and definitions given in GB/T 12936, GB/T 18713, GB/T 20095 and ISO 9488:1999 and the following apply.

3.1
solar-plus-supplementary water heating system
system that combines solar energy and supplementary energy and can provide the required hot water independently of solar energy

3.2
the coefficient of heat performance of solar-plus-supplementary water heating system
CHP
for the solar-plus-supplementary water heating system, the heat performance test of solar energy heating alone shall be carried out first, and then the heat performance test of solar-plus-supplementary water heating system shall be carried out. The ratio of the daily useful energy of the solar heating collector per unit contour aperture area inspected by the latter to the same performance index inspected by the former is the coefficient of heat performance of the system
