Abstract

The invention belongs to an automatic constant temperature test system for the heat performance of a solar water heater, which comprises a water pipeline system, an electrical control system and a data signal acquisition and analysis system and is characterized in that the water pipeline system is also provided with an automatic constant temperature water device, a backwater circulation utilizing device and a stable-pressure safety device so as to solve the problems of temperature control, heat preservation, and the like in a test process, enable a temperature deviation range of detected water to be controlled within a range from 0.2 DEG C below zero to 0.2 DEG C, and satisfy the detection requirements of the ISO9459-2 standard and the GB/T19141 standard. At the same time, the invention also solves the problems that the full-automatic, multi-station and all-weather detection and the recycling of water sources are difficult, thereby having obvious social benefits and economic benefits.

Description

technical field [0001] The invention belongs to a thermal performance test system of a solar water heater, in particular to an automatic constant temperature test system for a solar water heater by a mixed water drainage method that can simultaneously meet the requirements of the international ISO9459-2 standard and the national standard GB / T19141-2003. Background technique [0002] With the continuous improvement of the national standard system for solar water heaters, the inspection requirements for relevant technical indicators of water heaters have also been continuously improved.
