Labari game da Ma'aunin aikin injin sanyaya
Injin sanyaya injin ne da ke ɗaukar zafi daga wuri mai ƙarancin zafi, sannan ya mayar da shi zuwa wurin da ke da yawan zafin jiki. Domin wannan tsari ya faru, injin dole ne ya yi aikin domin zafin yana gudana daga yanayin zafi mai yawa zuwa yanayin zafi mai ƙasa. Wannan ya fito ne daga kalaman Clausius:
Ba zai yiwu ba ga injin sanyaya ya canja wurin zafi daga wuri mai ƙarancin zafi zuwa wuri mai zafi mai yawa, ba tare da aiki ba (Dokar thermodynamics ta biyu - bayanin Clausius).
Injin yana aiki (W) don canja wurin zafi, daga ƙarancin zafin jiki (Q L ) zuwa babban zafin jiki (Q H ). Dangane da kiyaye makamashi, Q L + W = Q H.
Idan injin zafi yana amfani da kalmar inganci, to injin sanyi yana amfani da kalmar coefficient of performance (C P ). Coefficient of performance (C P ) na injin daskarewa shine rabo tsakanin zafi da aka canja daga ƙarancin zafin jiki (Q L ) zuwa aiki (W), wanda ake yi don canja wurin zafi.
Mafi kyawun ma'aunin aiki na injin sanyaya:
TL = ƙarancin zafin jiki, TH = zafin jiki mai yawa
