冷凝式燃气热水器冷凝换热器热负荷实测研究

Research on Heat Load Measurement of Condensing Heat Exchanger for Condensing Gas Water Heater

将某型号冷凝式燃气热水器作为实验对象,在不同冷水进水压力条件下设定出水温度,进行热水器热效率、总热负荷、冷凝换热器热负荷实测计算。对热水器性能影响因素及冷凝换热器热负荷占总热负荷的比例进行计算分析。

Taking a certain type of condensing gas water heater for experimental subject, the outlet water temperature is set at different cold water inlet pres- sures to measure and calculate the thermal efficiency and total heat load of the water heater and the heat load of condensing heat exchanger. The factors influencing the water heater performance and the proportion of condensing heat exchanger heat load in the total heat load are calculated and analyzed.
