Portable Air Conditioner The portable air conditioner is an innovation product originally from standard air conditioning which is limited to being used in the room or inside the building. So, it's the easiest design to move from one place to another. This product is design looks like the tree of adornment that people mainly use as decoration in outdoor event like weddings and talk. As we all note that Malaysia has a tropical rainy climate due to its proximity to the equator. It is hot and humid throughout the year, with an average temperature of 27 ° C (80.6 ° F) and there is almost no variability in the annual temperature. Most Malays are finding a way to get comfort especially during the day. This air conditioner can help them produce a comfortable environment on the hot day. In addition, you do not have to rely on the conventional fan that continues to produce warm air but this laptop will give cool air just like the normal air conditioner than in close room. This portable air conditioner is equipped with photo sensor which can feel the existence of people in front of It will turn itself off automatically if there are no people and it will turn on again if it detects people crossing or standing in front of it.This will make it easier for people to turn it on or off manually, especially in the busy event. It is also economising the electricity when the use is continuously without use of people leading to lose energy. The present air conditioner is difficult to install especially to fit in outdoor environment. This product is design with wheel making it easier to move and install. With the simplest installation procedure, anyone can easily install the air conditioner where desired.

The air conditioning has been used in the past, where the weather is too hot for comfort. Cooling will increase the relative humidity of the air, so humidification is not usually incorporated into these systems. If necessary, the usual method is to inject steam boiled electrically. That's all there is to the part of the system in the room, which is outlined left in the figure. The little that is harder to understand, or at least unknown to most people, is how coolant Is produced and controlled. It is the part to the right of the diagram. Cooling fluid used to be a chlorofluorocarbon compound, and often remains, although they all more or less devastate the earth's ozone layer. The essential characteristics of these fluids is that they have a fairly low boiling point at atmospheric pressure and they can remain in the pipelines for a long time without decomposing with each other or the pipes. They finally need to have some lubricating ability, or the ability to carry a lubricant, because the fluid has to be compressed and pumped around the system. This rare set of necessary properties has proved difficult to combine with friendship with the Earth's atmosphere. The liquid is introduced into the refrigeration unit through valve B marked in the diagram. It evaporates as it passes through the pipe, taking the heat from the air just like the water that evaporates from a towel placed on your feverish brow cools you when on holiday in the Mediterranean. The temperature in the cooling coil depends in part on the amount of liquid letin by the valve, which is controlled by the thermostat or humidistat. But now comes a crucial difference from your Mediterranean experience: the minimum temperature on the cold surface can be set by controlling the pressure in the cooling coil, with the valve marked A in the diagram. The boiling point of any liquid depends on the pressure. Water could be used in the cooling coil if the pressure is kept low. At 1000 Pa of pressure, which seems a lot, but is only 1% of atmospheric pressure, water boils at 7 degrees. It is not used in cooling coils of this type evaporative because it has practical disadvantages.
