摘要

本文針對餐飲連鎖火鍋店之冷凍空調設備進行熱水回收系統之設計與實際案例分析，由現場測試之數據顯示，雖然熱水溫度於用水尖峰期溫度稍有下降，但平均熱水溫度45℃仍符合業者正常使用，不僅改善過去電熱水器耗電水溫穩定度及安全性不足等問題，並可以完全省掉原熱水系統之初始建置成本，而經實際估算其每天熱水用量，則本案建構之冷凍空調設備熱回系統，每年可協助業者節省至少15萬元電費，回收年限約在1.5年。

This paper aims to design and analyze the heat recovery system of refrigeration and air-conditioning (AC) equipment built in local chain restaurants. From the field measuring and monitoring data, the hot water temperature becomes lower when lots of water is used in the restaurant, but the water temperature around 45℃ is satisfactory to the staff in the kitchen. We not only improve the deficiencies such as power consumption, stability of supplying water temperature and safety of the electric heating water systems in the past, but could save the initial cost of the equipment for the owners. Based on the estimated quantity of the used hot water each day, the owners can save at least NT$ 150,000 electricity bill and return of investment (ROI) is about one and a half years.
