Therefore, appropriate fresh air must be drawn in. When the water evaporates from the surface of an indoor swimming pool, the exhausted air will include excessive moisture and high emthalpy values. In order to abide by the indoor requirements, heat pump is usually utilized to engage in dehumidification and heating functions on the air. In order to reduce energy consumption costs, a solar power system is usually added in order to decrease the energy cost of the boiler. This system uses different heat pumps along with different V/A values (the ratio of the water tank volume and the flat-plate solar collectors’ size), different ratio of outside air, and a different number of flat plate solar collectors. Then, the boiler will assist in the heating. When the heat provided by the solar energy and heat pump causes the water temperature of the water tank to be over 40℃, the water sent in from the water tank would not need to be heated by the boiler. When the water temperature of the water tank is less than 40℃, the water sent in from the water tank would need to be heated by the boiler to 40℃. From the analysis we can see that under similar outside air environments, how the lowering of the operational costs would be. In addition, we can compare the duration of return-on-investment. The system will use the yearly operational cost and the system’s initial costs to calculate its total life cycle cost. Thus, a practical system with faster investment return years could be chosen.
