Hello,
If i change ambient temp by 1 deg higher in my equation i get these results:
QL1 = 9639.85W; Win1 =3069W; QH1 =12708W
If I change ambient temp +1 = 25+1 degs C. and i do not change Refrigerator temp = 3deg C (unchanged), i get:
QL1 =9392.37W; Win1 = 2990W; QH1 =12382W
Ql=evap.
Win=Compressor
Qh=condenser.
So I am increasing ambient temp (room temp) by 1 deg. and keeping the refrigerator the same temp. I get reduction of evaporator heat transfer, compressor work input and also QH. COPis the same as the reductions are proportional to each other. I understand that heat flows easier where there is a bigger temp difference but still didnt expect all reductions.
Is this equation i'm using sane or insane? in respect of these results?
Please help, thank you
