AIR CONDITIONING IS a field of engineering dealing with the design, construction, and operation of equipment used in establishing and maintaining desirable indoor air conditions. It is the science of maintaining the atmosphere of an enclosure at any required temperature, humidity, and purity. As such, air conditioning involves the cooling, heating, dehumidifying, ventilating, and purifying of air.
Room fans stir up the air. The temperature inside your house can he several degrees cooler than outside, but it can seem warmer if the air does not move. Also, air movement increases moisture evaporation, and moisture evaporation cools the body, or skin surfaces. Attic and window fans exchange inside air for outside air. Humidifiers, air cleaners, and dehumidifiers clean and filter the air in your home, removing air-borne pollen and dust particles. Another method of air cooling you should consider is the heat pump. The heat pump is a single unit that replaces the conventional furnace air conditioner system. It removes heat from your home in summer and supplies heat to your home in the winter. The heat removed in the summer is discharged to the outside air.
For years the best engineering minds have been working on home !wrung systems with the result that today there is a vast array of devices that solve many more heating, cooling, and air conditioning unit ( than we ever thought existed a few years ago).
Air conditioning is the best way to keep your house at a constant, cool temperature. But it is also more expensive than other methods of cooling.
There are two types of air conditioners.
1. Room units.
2. Central-system units.
The cooling operation of both types of air conditioners is the same. Air passes through filters that remove large dust particles, and over a series of Appliance coils, where it is cooled and dehumidified. A fan then blows the cooled air into your home.
Most air conditioners have either built-in thermostats or provisions for wiring the conditioners to remote temperature controls. Some of the small units are not thermostat equipped, but you may find a thermostat is available as optional equipment. Room air conditioners cool one or more rooms. They range in out)Ut from about 5,000 to 32,000 British thermal units (Btu's) per Boor. They operate on electricity only, and should have separate electrical circuits (this may require adding a circuit to your home). You may choose from many available models?models for conventional windows, models for casement windows, models for in front-of-window consoles, and models that mount in special wall openings. But before you buy a room unit, think. You will probably need several small units to cool your whole house. Single, large room milt will be less expensive, but it will not cool your home evenly.
A central air conditioning system might be a better buy.
Central air conditioning systems are generally more efficient than room air conditioners. They also seem less noisy because they are located out of the living area. But a central system may be unnecessarily expensive to install if you live in an older house, in an apartment, or in a climate where air conditioning is needed only occasionally for short times. One or more room conditioners may be the answer.
Central air conditioning systems can be separate systems with their own ducts, or they can be combined with forced air heating systems. Cooling requires a greater amount of air flow than heating. If you choose an add-on system it will probably be necessary to increase the fan capacity of your furnace, and it may be necessary to enlarge and even relocate the distribution ducts. Larger ducts also decrease the velocity of the cooled air and reduce the noise of air conditioning.
For greatest uniformity in room comfort conditions, cold air supply grilles should be high in walls or in the ceiling and hot air supply grilles should be near or in the floor. If economy dictates use of only one grille for both heating and cooling, the near floor location is preferred. The cost of purchasing and installing a central air conditioning system will depend, to a large extent, on whether you choose a separate central system, or a system to be added to your heating system.
Most room air conditioners have air-cooled condensers. This means that the condenser must be outside the cooled room, that it must have unrestricted air circulation over the condenser coils, and that it should be shaded from the sun. Some air conditioners have water-cooled condensers. They require large quantities of water to disperse the heat?approximately 70 gallons to 150 gallons per hour for each 12,000 Btu's of cooling capacity. This water can be cooled in a cooling tower and reused. Locate the tower outdoors, away from your house; it is noisy.
Air-cooled units require more electric energy than water-cooled units. This increased cost is usually offset by water supply and disposal (or cooling tower) costs. Air conditioners are rated by heat-removing capacity in British thermal units (Btu's). Where temperatures do not usually exceed 95° F., an air conditioner rated at 6,000 Btu's per hour will cool a room with 100 to 230 square feet of floor space. Where temperatures exceed 95° F. but do not exceed 100° F., an air conditioner rated at 6,900 Btu's is required to cool the same area. Approximately one kilowatt-hour of electricity is required to remove each 6,500 Btu's with an electrical air conditioner. This is the same amount of electricity that is required to operate ten 100-watt Light bulbs for one hour. A water-cooled gas air conditioner requires about 13 cubic feet of gas (plus a small amount of electricity) to remove each 6,500 Btu's. An air-cooled gas air conditioner -requires 21 cubic feet of gas (plus a small amount of electricity) to remove each 6,500 Btu's.
Central-system air conditioners are sometimes rated in "tons." One ton of Appliance equals 288,000 Btu's per 24 hours, or 12,000 Btu's per hour. Not all air conditioners dehumidify adequately during humid, muggy weather. The result is that the cooled air they put out feels clammy. This clamminess can be reduced, to a certain extent, by operating a dehumidifier when you operate your air conditioner. When you set out to buy a room air conditioner, remember that it is essentially a heat pump. Its main job is to take heat from your room and discharge it into outside air. To be able to do this efficiently, a conditioner must fit its window and be compatible with your home wiring. With these requirements in mind, you can concentrate on four main questions in selecting a conditioner to fit your particular needs.
1. How much cooling should the conditioner provide?
2. What kind of window will it have to fit?
3. What is the electrical capacity of the wiring in your home? C,
4. What practical and convenience features should you look for?
The answers to these questions may save you a great deal of expense and trouble.
