Air Conditioning Controller - Is that part of an air conditioning that controls the system, and makes it function automatically.
Air Conditioning Controller - When we talk about an air conditioner, we talk about a machine that is able, to cool for example the air inside a living-room, to let's say 20 degrees Celsius, making the environment to live in more comfortable, even when the temperature outside is high. The unit that controls this machine is the air or climate conditioning controller. Air conditioning works as follows: the heat of the hot inside air of a room is removed by letting a colder medium absorb the heat. The inside air is blown over the evaporator, containing the evaporated fluid, that is cooler than the inside air and absorbs the heat. This evaporated fluid then goes to the compressor, where it is being compressed. After this compression, this evaporated fluid becomes hotter then the outside air. Thus letting outside air passing over the condenser extracts the heat, and the vapor condenses to a fluid. The fluid is now colder then the inside air. And then it goes back inside the building, via the evaporator, and this cycle repeats itself. It is clear that a controller unit is needed to master this process. In low cost air-con units this is a pure mechanical unit. In more advanced systems an electronic unit measures the four different temperatures: outside temperature, inside temperature, compressor temperature and the evaporatortemperature. Also the pressure is monitored. In return the electronic unit, after the necessary calculations, adjust the process, so that we get the programmed inside air temperature.
