各位版友大家好
小弟最近被一題heat pump困擾許久不得其解
故想請教一下以下問題
http://www.wretch.cc/album/show.php?i=syounihon47&b=19&f=1747425762&p=4
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
