Refrigerators

I understood this when I read it in TBR, but I just reread a similar section in EK and got confused.

If we put a running refrigerator in a small closet, close the closet door and open the refrigerator door what will happen to the temperature of the closet?

The closet will warm up because qh is greater than qc.

EK defines qh as the heat entering the refrigerator and qc as the heat leaving the refrigerator.

Doesn't the closet warm up because qc is greater than qh?

Uhhhhh, kind of vague as written. Dunno if the question is vague though.

If you have a fridge that has been running for some time, put it in a closet, and open the door, you'll initially cool the closet down due to the stored coolness inside the fridge. If you put a warm fridge and a closet, open the door, and turn it on, you'll warm it up from the get go (1st law of thermodynamics coupled with perfect machines being nonexistant)
