: 關於求heat pump的輸入功率方面 我求出來的(功率in)hp竟然為负值?!
: 想法為:
: 在冬天的時候
: (熱傳率)L=0.44*28=12.32KW
: 再利用熱力第一定律 (熱傳率)L+(功率in)hp=0
: 故得 (功率in)hp=-12.32KW
: (功率out)hp=12.32KW
: heat pump的功率怎麼可能是out? = =|||
: 以上 懇請賜教 感激不盡
首先 謝謝大家的指點迷津(板上真的是高手如雲阿)
但小弟不才沒能完全理解或是我傳達的不好 於是將過程獻醜如下
真的很想知道過程跟系統圖是錯在哪邊? 且為何課本可以解的如此輕鬆?
請大家鞭小力一點....我會努力學習的^^
