The thermodynamic efficiency of the heat pump is higher the higher the temperature of the cold side, so at least in places where the outside temperature is warmer than the fridge or freezer this wouldn't be a win. This is why you can improve the performance of a heat pump by having the outside circuit run under the ground where the temperature is warmer.
There's also the point that the fridge/freezer is already a heat pump dumping its heat into your house.
- dlhavema 7y agoRight could we focus that? I'm not sure how much heat it is but I dont like the idea of the fridge just dumping heat into my kitchen while the air pumps push cold air into the same room
- Firadeoclus 7y agoThe cooler your kitchen is to begin with, the less heat the fridge needs to dump.
