| It needs some extra valves to switch the flow of coolant around, but yes. |

| Some refrigerants are more suited for cold climates, some of which require very high pressures. |

| In the same way that an electric motor and a generator are the same thing. |

| I think they mean "air exchange" (split AC) vs "heat pump" (dig into the earth to draw/eliminate heat). Not saying that's the right definition though. I am guessing at an auto-correction of what they meant. |

| ▲ | ane 3 hours ago | parent | prev [-] | | A heat pump is not necessarily dug into the earth. Rather, the flow of the heat pump is moving heat (thermal energy) from outdoors to indoors or the other way around in an air conditioner. Depending on the direction of the coolant flow, you get either a indoor heating or cooling unit. This is best demonstrated by going in front of the outdoor unit of a heat pump, when they are cooling, the outdoor unit generates heat because it's compressing gas, which then is then expanded when it reaches the indoor unit, generating cold. Exactly like a refridgerator. |
