The air conditioner in cars can blow hot and cold air, which is activated by turning the dial. Red means warm or hot, blue means cold.

Why are air conditioners placed high on walls and not on the ground?
Because the cool air from the air conditioner is denser than the warm air in the room and sinks. Placed high up the cool air will have time to get further from the air conditioner before it settles to the floor, allowing it to cool more of the room. Placed on the floor the cool air will mostly pool around the air conditioner and very little of the room will be cooled. Some air conditioner are actually placed relatively low in a room, but they have fans and baffles that blow the cold air upwards to the ceiling resulting in the same effect as placing the air conditioner high (maybe even better as the fan blows the cool air not only up to the ceiling but across it, possibly covering a larger volume of the room than cool air falling passively from an air conditioner placed high but without fans).
Why does an air conditioner must cycle on and off to keep the room cooled to a preset temperature?
Seriously? Cold air blows out of the air conditioner when it's on, reducing the temperature of the room. When the temperature in the room reaches some preset value, the air conditioner shuts off to prevent the temperature from dropping any lower. Once the air conditioner is shut off, heat sources within the room including people, appliances, and heat entering through walls and windows causes the temperature in the room to increase. When this happens the air conditioner kicks on again to bring the temperature back down. It ain't rocket science.
How does a heat pump function?
The simple analogy I use when teaching HVAC classes to describe an "air-to-air Heat Pump" goes like this:Think of a window air conditioner. When it runs, it blows cold air into your room, and hot air outdoors. What it's actually doing is transferring the heat from your room to outside.What if you could turn the window air conditioner around in cold weather? Then it would blow the warm air that used to go outdoors into your room, while it "air conditioned" the outside.That's how a Heat Pump works. It doesn't physically move the components of the air conditioner around, but it reverses the direction of refrigerant flow so that it "air conditions" the outdoors while heating your house.The HVAC Veteran
