The Air Conditioner is my Heater?!

Air Conditioners don’t necessarily just cool your building. An air conditioner essentially moves heat from one place to another. In the case of your typical AC set up, we absorb the heat in your office and we put it outside with a gigantic condenser coil. What if we did the opposite?   Air Conditioning the Outside Speaking in terms of pure-physics, there’s pretty much always heat outside. To us living, breathing creatures, 0 degrees may seem like there is no-heat, but to a physicist, that’s orders of magnitude above the coldest cold possible “absolute zero.” That means we can put that ‘heat’ to use. In a configuration like this, the outdoor coil will become incredibly cold. This will allow it to absorb heat from the outside air and bring it indoors. Inside, the refrigerant is condensed and we basically get heat. We’re literally switching the roles of a traditional air conditioner. Systems such as this are often called Heat Pumps. Technically speaking, anything that moves warmth is a heat-pump, even an air conditioner or a fridge, but the term in particular is related to using air conditioning hardware for heating purposes.   The Extra Hardware Achieving this requires some special tweaks. If we’re going to have an air-conditioning-heater, we need some extra valves, control logic, and tweaking the design of your coils. Your coils will now both be able to function as evaporator and condenser coils. There’ll be two expansion […]
