摘要

室內溫水游泳池要維持室內所需的條件，主要有濕度和溫度，所以必須引進適當的新鮮空氣，當室內泳池表面有水分蒸發，使排氣的空氣包含過多的水分和較高的焓值，為了維持室內的條件，通常利用熱泵對空氣進行除濕和加熱的功用，為了減少能源消耗的費用多加入太陽能系統，以減少鍋爐所消耗的能源成本。
本系統使用不同熱泵搭配不同的V/A值(儲水槽容量與太陽能集熱板面積的比例)、不同的外氣比例、不同的太陽能片數再搭配與鍋爐輔助加熱，在太陽能及熱泵所提供的熱源使儲水槽的水溫高於40℃時，從儲水槽補進泳池的水可以不需鍋爐輔助加熱；若儲水槽水溫低於40℃時，從儲水槽補進泳池的水加以鍋爐輔助加熱至40℃，可分析看出在相同外氣環境下降低其運轉成本的匹配情況，並比較回收運轉年數，以每年運轉的費用及系統初設成本來計算其總生命週期成本，如此可以選出一套實用且回收年限較短的系統來使用。

An indoor lukewarm swimming pool has to meet the requirements necessary for indoors. The main requirements are humidity and temperature. 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.
