Temperature distribution in a hot water storage tank, which affects the performance of a CO_2 heat pump water heating system, is analyzed by three-dimensional thermo-fluid analysis. Moreover, the analyzed temperature distribution is compared with that by one-dimensional analysis, in which it is assumed that hot water moves only vertically inside the tank. In particular, the temperature distribution in a revised system where middle hot water is extracted from middle position of the tank is analyzed. By the analysis, the qualitative validity of the one-dimensional analysis is clarified.
