Article Preview

To research for application of thermodiode in energy storage solar water heater, experimental research on heat transfer of thermodiode using myristic acid as heat storage material was made, starting characteristics of thermodiode using acetone and R134a was compared. Especially for working fluid of R134a, influence of thermodiode on heat storage process of myristic acid was tested for under different working conditions such as thermodiode’s positions, liquid charge ratios, etc. Test result shows, thermodiode charged with R134a was quicker in start-up than the case of myristic acid; with liquid charge ratio of 80% , heat transfer coefficient was the highest; with an inclination angle η=30°C of thermodiode plane to horizontal plane, an inclination angle α=10°C of heating-evaporating section to horizontal line, 25W power input and a liquid charge ratio of 80%, average heat transfer coefficient was 113 W/(m2·K).
