If I can spend 1 joule to transfer two joules of enthalpy from outside to inside, then that is 200% efficiency.
Burning 1 joule of gas would give you 1 joule of heat in a perfect world. That is what a non pump does.
- vikingerik 4y agoWhere exactly does that first spent joule go, thermodynamically speaking? Is it also converted to heat within the electromechanicals of the heat pump?
- SigmundA 4y agoYes so not only are you capturing heat from the environment you are turning electricity into heat in the compressor, both are delivered as heat to the interior. This is an advantage compared to cooling where you must reject both the interior heat and the heat of compression.
- kenmacd 4y agoTo add to the other answer, if you calculate the absolute limit on performance for heating and cooling using the Carnot cycle, the 'heating' case is always going to be '1' higher than the cooling case, because you also get to use the 'work' heat.
