| Abstract: | The influence of the ambient temperature in laboratory and the gas temperature on the thermal efficiency of gas water heater is analyzed through the theoretical calculation of thermal efficiency. The influence of the variation of cold water inlet temperature on the thermal efficiency of gas water heater is analyzed by the experimental test. It is concluded that the optimal temperature conditions for the test and calculation of the thermal efficiency of gas water heater are that the ambient temperature in laboratory, the gas temperature and the cold water inlet temperature are all equal. |
