An air conditioner is a device which uses a special type of substance which readily changes from its normal gas state to a liquid one (Typically freon or another refrigerant such as R-20 [chloroform] or R-134 [tetrafluoroethane]). The gas is contained in a closed circuit of pipes connected to a pump. The pump compresses the gas so hard that the pressure is great enough for it to turn into a liquid. In doing this the gas/liquid has got hot (If you try to compress a gas, it will almost always get hot - think of a bike pump when you pump up a tyre (tire), the greater the pressure in the tyre, the hotter the pump gets).
Now the hot liquid travels round a set of pipes which allow the heat to escape. Next the liquid under pressure passes through a valve into a pipe where the pressure is much lower, and the liquid evaporates back into its gas state. In doing this it needs to take in heat from its surroundings, thus making the pipes colder. The gas now gets back to the pump and the whole cycle starts again.
The pipes are usually arranged so that there are fans to blow air over both the hot part of the pipes and the cold part. The hot part is frequently put outside the house, and the cold part inside. This is called either a 'split pack', or a 'twin pack' depending on which country you are in There are also portable versions which have both parts in the same box, with the cold air blowing out of the front, and the hot air blowing out of a flexible hose which you put put outside the room to allow the hot air to dissipate.
The air conditioner in a central heating and cooling system provides cool air through ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat. ... From that point, the condenser or outdoor unit then turns the refrigerant vapor back into a liquid, removing any heat.

Portable air conditioning is great for work or any place where you have different preferences than other people. It would not, however, be a good replacement for a home air conditioning system.
A day and night air conditioning system does not work at all as it is a scam and it is really the same system. There are no difference to its operating systems.
Air conditioning allowed people in hot climates to be more productive. It allowed them to work in occupations that would be dangerous from the heat. Air conditioning added the element of safety to hot occupations.
On some systems (such as air conditioning).
Central air conditioning provide a uniform distribution of cool air in your home or work place. It creates a more comfortable environment. 80% of new homes built in the United States are built with central air conditioning.
Most states require an HVAC certification for performing work on heating and air conditioning systems. While not all employees of a heating and air conditioning company need to be certified, at least one employee on the job should be.
