Room air conditioners

Room air conditioners frequently are difficult or impossible for the home handyman to repair, and central air conditioning systems are even more so. But here’s help with several air conditioning malfunctions that you can fix.

How an air conditioning operate

The air conditioning motor permits the refrigerant to circulate through the various valves and galleries of the air conditioning compressor and through the tubes of the system. When it leaves the compressor under high pressure, the temperature of the vaporized refrigerant is about 210° F. The hot gas is forced from the air conditioning compressor through a tube to the outside of the house where it enters the tubing of the condenser. The job of the condenser is to do exactly what its name implies to allow the gas to condense, thereby cooling down. Assisting the air conditioning condenser in this task is a fan that blows air across the condenser coil. This cooler air blown across the condenser by the fan drops the temperature of the vaporized refrigerant to about 115° F., which is sufficient to let the vaporized refrigerant revert to liquid form. At 115° F., refrigerant even in liquid form is not able to cool any area except one exceeding 115° F. It is a law of physics that warm air travels toward a cooler area. To make a hot room cool, then, heat has to be drawn toward the coolness of the air conditioner, and when we speak of the coolness of the air conditioner we really mean the refrigerant. But at 115° F.? To get the refrigerant to a temperature at which it will be an effective cooling agent—specifically, to about 45° F. the liquid refrigerant leaving liquid is permitted to expand suddenly (when pressure on it is relieved), its temperature drops. Assisting the refrigerant in dropping its temperature even further is another fan that is blowing across the air conditioning evaporator coil. The liquid refrigerant enters the evaporator coil from the expansion valve at the lowest temperature it can expand, rapidly reduces the efficiency of the unit and wastes attain, and the hot, humid air in the room moves toward it. The humidity of the air drops and the air cools. The moisture that air conditioning condenses on the evaporator coil is carried off by a drain tube and is ejected outside the house. The liquid refrigerant absorbing all this heat gets very hot again and vaporizes. Back it goes to the compressor, and the whole cycle starts all over.

Air conditioning maintenance: a task for even the non-handyman

YOU MIGHT NOT BE ABLE to make air conditioning repairs, but you can forestall breakdowns by taking care of your unit. The following maintenance procedures are suggested:
1. Keep the air filter clean. A dirty filter restricts the flow of air, reducing cooling efficiency and adding to the cost of operating the unit. An air conditioner has one of energy and two types of filters: fiberglass or a permanent, germicidal sponge-type. Fiberglass filters should be replaced. The permanent-type filter may be washed in soapy water, rinsed in fresh water, and squeezed dry. The U.S. General Services Administration recommends that air-conditioner filters be cleaned or changed once a month during the cooling season.
2. Every year, the air-conditioner compartment should be cleaned. The most complete way of doing this is to slide or remove the unit from its chassis so all parts can be reached. There are two types of room air conditioner chassis. One type allows you to slide the unit out like a drawer. The other type requires that the unit be removed from its position in the window or wall. With the system exposed, remove dirt and lint from the condenser and evaporator by vacuuming them. Wipe crusted dirt from the compressor, fan, Examine the outside case (which is usually metal) for rust every year or two. Scrape rust off with a putty knife and touch up the spot with a metal primer and paint. Protect your air conditioner during winter by covering it with a cover.
