摘要

本研究以室內溫水游泳池為研究對象，運用空氣熱泵系統維持室內溫水游泳池空調所需的條件，並以空氣熱泵收集室內高濕熱空氣的熱能。藉由空氣熱能的回收，運用在除濕後冷空氣再熱所需之熱源及池水的持溫加熱系統上，以達到能源之再利用及節能的效益。
本文中之熱泵系統以壓縮機、冷凝器、膨脹閥與蒸發器等四大部分原件進行設計及搭配 ，除了壓縮機和膨脹閥的部分是以製造商所提供的性能曲線為基礎作分析外，冷凝器和蒸發器之熱交換器均是由基本的動量、能量守恆方程式開始，經由適當的假設來計算，並分別建立一維的理論模式來加以分析以求取得最佳熱泵系統的組配件並建立資料庫。
研究後發現如以不同組合之熱泵與鍋爐供應熱源來做比較，並以生命週期成本來作分析，可得知十年後CaseE之總花費為NT18,177,380元，為五種Case中最具有經濟效益的方案，以二年之生命週期成本來做分析時，則以CaseB為最符合經濟效益，而初設成本方面，CaseA最為經濟。若以CaseA熱泵適當的增加熱交換器UAc與UAe導熱度之分配比例來做分析，預估五年後以Case3之UAc與UAe導熱度分配比例值為1.37時與CaseA作比較可節省生命週期成本約NT1,729,854元，總初設成本約只增加NT137,132元的費用，所以適當增加導熱度分配比例也是增強熱泵性能的方法之一。

Objective of this study is to investigate the effect of heat pump system on the Winter indoor swimming pool in warm water. The heat pump system is the conditioner which controls the indoor temperature and moisture content in swimming pool. It is also used for collecting & recycling the heat energy from indoor high temperature & moisture content. In order to achieve the goal of energy recycling and saving, the recycled heat is further processed for keeping the indoor and water temperature.
The Heat Pump System was designed by combining four major components such as compressor, evaporator, expansion valve and condenser. The analysis of the compressor and thermostatic expansion valve is based on the standardized performance curve provided by the manufacturers. The performance of condenser and evaporator is modeled and calculated by using the fundamental physical laws of mass, momentum and energy conversation in one-dimension steady-state flow, in order to establish a consistent theorical model for achieving optimal performance of the components in the Heat Pump System and for constructing a data base for future reference.
In this study it was observed that if we compare the heat source from different combinations of heat pump and boiler, based on the economical analysis, the total cost of case E is NT 18,177,380 dollars, which has the greatest economic benefit among the five cases. If the budget of two-year life expectancy is analyzed, case B will provide the best economic benefit. Regarding to initial budget, case A is the most economical one. It was observed that if the heat pump in case A can appropriately increase the distributing ratio of heat conductance between heat exchanger UAc and UAe, it is estimated that after five years if the UAc and UAe ratio is set to be 1.37 which is compared with that of Case A, the life expectancy budget of NT 1,729,854 dollars can be saved. The initial budget limit was up to NT 137,132. Therefore appropriately increase the distributing ratio of heat conductance is also one of the methods to enhance the performance of heat pump.
