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
