How an Air Conditioner Works
  Taken literally, air conditioning includes the cooling and heating of air, cleaning it and controlling its moisture level: conditioning it to provide maximum indoor comfort

An air conditioner transfers heat from the inside of a building, where it is not wanted, to the outside. Refrigerant in the system absorbs the excess heat and is pumped through a closed system of piping to an outside coil. A fan blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air. Because the heat is removed from the indoor air, the indoor area is cooled.

An air conditioning system generally consists of five mechanical components:

1. A compressor
2. A fan
3. A condenser coil (hot)
4. An evaporator coil (cool)
5. A chemical refrigerant

Most central air conditioning systems include of a "hot" side, outside your home, and a "cold" side, inside your home. The "hot" side generally consists of a condensing coil, a compressor and a fan.

The "cold" side is usually located within your furnace. The furnace blows air through an evaporator coil, which cools the air, and routes this cool air throughout your home using a series of air ducts.

The cleaning function of air conditioners is performed by filters, which remove dust from the air.
How a Heat Pump Works
  A heat pump is like a conventional air conditioner except it also can provide heat in winter. In the summer, the heat pump collects heat from the house and expels it outside. In the winter, the heat pump extracts heat from outside air and circulates it inside the house. The heat pump works best when the outdoor temperature is above freezing. Below that, supplementary heat often is needed. A heat pump can save 30 to 60 percent less energy to supply the same heat when compared to an electric furnace with a resistance heating element.

COOLING CYCLE -- Refrigerant passes through the indoor coil, evaporating from a liquid to a vapor. As the liquid evaporates, it absorbs heat, cooling the air around the coil. An indoor fan pushes this cooled air through ducts inside the house. Meanwhile, the vaporized refrigerant laden with heat, passes through a compressor which compresses the vapor, raising its temperature and pressure. The reversing valve directs the flow of hot, high pressure vapor to the outdoor coil where the heat released during condensation is fanned into the outdoor air, and the cycle begins again.

HEATING CYCLE -- Note that the slide inside the reversing valve has shifted, causing the refrigerant flow to reverse. Liquid refrigerant now flows to the outdoor coil picking up heat as it evaporates into a low pressure vapor. The vapor travels through the compressor where it is compressed into a hot, high pressure vapor, then is directed by the reversing valve to the indoor coil. The vapor turns into liquid as it passes through the indoor coil, releasing heat that is pushed through the ducts by the indoor fan.
Carbon Monoxide Detectors
  Should I be concerned about carbon monoxide poisoning?

Carbon monoxide is an invisible threat to your health and safety. Though more commonly associated with fires and automobile emissions, carbon monoxide poisoning can occur in any office or home unless certain precautions are taken.

What is carbon monoxide?

Carbon monoxide (CO) is a colorless, odorless, tasteless gas that is produced by the incomplete combustion of fuels such as wood, oil, natural gas, gasoline, diesel, kerosene, coal and charcoal. It is caused by lack of oxygen or a disruption in the burning process.

What are the effects of carbon monoxide on the human body?

When we breathe, carbon monoxide displaces the oxygen our bodies need to survive and creates a condition known as carboxyhemoglobin saturation.

What are the symptoms of carbon monoxide poisoning?

Unfortunately, the symptoms caused by carboxyhemoglobin saturation are easily overlooked because they are often flu-like. With mild exposure, most people experience headaches, fatigue and nausea. Medium exposure can cause a severe throbbing headache, drowsiness, disorientation, confusion and an accelerated heart rate. Extreme exposure can lead to unconsciousness, convulsions, cardio-respiratory failure, coma and possibly death.

Why are new buildings and homes more susceptible to CO poisoning?

Newer facilities are better sealed to prevent heating and cooling leaks, which keeps energy use low. As a result, these homes limit ventilation. Normally, a building breathes in air from the outside to replace air being used by combustion equipment and appliances. If a structure is too well-sealed, equipment and appliances may become starved for the air that allows them to operate properly. When that happens, vent reversal may occur. But even older, less energy-efficient buildings can be vulnerable to the threat of carbon monoxide poisoning, particularly if the equipment has been improperly installed and maintained.

What can be done to protect people from the danger of CO poisoning?

Prevention is the most important step. Taking proper safety measures will reduce your risk of carbon monoxide poisoning. Heating systems are only one of the many potential sources of carbon monoxide. They are designed to be safe, efficient and not produce carbon monoxide. However, older heating units can experience cracked heat exchangers, which can pose a carbon monoxide threat. That's why it is important to schedule annual maintenance visits by a qualified technician to check combustion appliances to make sure they are operating properly and to be sure that all chimneys and vents are connected properly and not blocked.

The best method of detection is to use a carbon monoxide detector. A carbon monoxide detector is a device, very similar to a smoke alarm. It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected. Ideally, you should have one detector adjacent to occupied areas. Early carbon monoxide detectors were not very reliable and produced false alarms at low levels. The newer detectors overcome these early problems. Carbon monoxide detectors are most effective when used in combination with preventive maintenance. For more information on this subject contact Air-Heat America. 770-368-8050
