| Abstract: | The direct expansion solar heat pump hot water system was carried on some experimental researches. During the experiment, the solar irradiance range was 143.12 ～664.6W/m^2. Using three different structure of the collector/ evaporator respectively, the system＇ COP was 2.49 -3.47. Under various weather conditions ,which showed that the system was able to reliably produce 45℃ hot water and its thermal performance was stable, in a word, this system can provide hot water all day and have energy saving effect;At the same time, two groups data of double collector/evaporator were selected to analyse the influence of solar irradiance on the heat pump system. |
