Experiment study on performance of multistage water tanks heat storage applied to solar air conditioning.

The system of multistage tanks applied to the solar air conditioning was presented. Above the theoretical analyzing, the system of multistage tanks test-bed has been built to study the performance of the multistage tanks system with different series. The results showed that: the heat storage consuming time of the first-stage tank decreased and the heat storage grade improved with increasing the system series, and the time of ideal heating inlet water temperature increased with increasing the system series, in the heat release period, the conclusion is opposite. According to the above conclusion, the optimization strategy for the system of multistage tanks was proposed, the system after optimization has obvious effect prolonging the time of ideal heating inlet water temperature.
