Energy Efficient

Aug 8, 2018
Efficiency is not the way to describe such a system.
An Airconditioner is just a heat pump, as is a fridge or freezer A reverse cycle A/C init can "pump" heat in both directions, whereas all other units are uni-directional heat pumps.
If you compare the "heating" ability of a heat pump to a normal heater, you could say that the heat pump is "more efficient at heating a space. But IF you analyse the complete system then you may be rather surprised at the outcome.
Sure, but the important figure is how much heating you get per kWh (i.e. per rand) that you put in. No one really thinks about thermodynamics when they're talking about heating efficiency, methinks.
