TECHNICAL INFORMATION: AIR CONDITIONER
Air conditioning is the conditioning of air in a defined space, usually a residence or maybe a place of business. Health usually requires heating or perhaps cooling, humidifying or dehumidifying and blocking or washing air. If you have a central air conditioner, your whole body cools and dehumidifies the defined space. Following a few background, this kind of technical information provides information regarding three key parts of the environment conditioning device:
- Chilling Tower
- Air compressor
- Chilled Water System
An ac is basically a refrigerator with no insulated package. A typical air conditioning unit is doing precisely the same thing in exactly the same way. You can view a typical air conditioning unit with this kind of diagram:
Air conditioning Tower
In ac systems air is used to dissipate the heat from the outside coil. In some systems, the efficiency can be better significantly by using a cooling tower system. The air conditioning tower provides an impressive stream of lower-temperature normal water. This normal water runs by using a heat exchanger and cools the hot shelves of the air conditioning unit unit. This costs more to acquire the system initially, but the energy savings can be significant (especially in areas with low humidity) as time passes and the program pays for on its own fairly quickly.
Chilling towers appear in all shapes and sizes:

However , they all work on similar principle. A cooling structure blows air flow through a stream of normal water so that a few of the water evaporates. Generally the normal water trickles by using a thick bed sheet of an open plastic nylon uppers, and atmosphere blows through the mesh by right sides to the water flow. The evaporation cools the stream of water. Because some of the water is usually lost to evaporation, the cooling tower constantly adds water towards the system to generate up the difference.
The compressor compresses amazing freon gas, causing that to become popular, high-pressure freon gas (red in the diagram). This warm gas works through a group of coils so that it can dissipate its warmth, and it condenses into a liquid in the act. The freon liquid runs through an development value, in addition to the process that evaporates to become cold, low-pressure freon gas (light green in the diagram). This cold gas operates through a set of coils that allow the gas to absorb warmth and cool down the air inside building. The compressor is the central engine of the air conditioner. It’s the part that runs the complete system. The compressor is usually rated in BTU. A BTU is usually, generally, how much heat required to raise the heat of one pound of drinking water one level F. Especially, a BTU is 1, 055 joules, but the initially definition is a lot easier to understand. One particular ton, in heating and cooling conditions, is doze, 000 BTUs.
A typical air conditioner could be rated by 10, 1000 BTUs. What that means is usually that the air conditioner is able to cool 15, 000 pounds of water (about you, 200 gallons) one level in one hour. Or it could cool 5, 000 pounds 2 degrees in one hour. Or 2, 500 pounds 4 levels in one hour, and so on.
Perfectly chilled Water System
In a chilled water system, the entire air conditioner lives on the roof or behind the building, and this cools water to forty or forty-five degrees Farrenheit. This chilled water is then piped through the building and connected to surroundings handlers while needed. There is no practical limit to the period of a chilled faucet if it is well-insulated. The heat exchanger lets the cold freon chill water that runs throughout the building.
The York edition of the air conditioner offers the subsequent performance requirements:
- Maximum circuit ampacity is 11. 7
- Normal voltage ranges from 187 to 252
- Dimensions are 19x35x23
- Product charge is 4 lbs. 3 ounces
