Heating and Air Conditioning

In states where extreme temperatures are experienced, both heating and air conditioning (HVAC) is necessary to maintain a comfortable atmosphere in the home and the work place. The earliest version of the combined heating and air system consisted of pipes which conveyed hot or cold water as needed to regulate the temperature. Today, it has been realized that simple change of temperature is not enough. In order to ensure the good health of the inhabitants, it is necessary to install a ventilation system as well which will get rid of stale air and pump in fresh air. The result is the modern HVAC unit or the heating ventilation air conditioning unit.

How does Combined Heating and Air Conditioning Work?

The system of heating and air is so designed that the temperature inside the building is always maintained at a comfortable level.

The heating is achieved in many different ways. Today, central heating is the most popular. Hydronic system is used where water is heated in boilers and then circulated with the help of underfloor pipes. However, such systems are prone to be economically affected by changes in heating oil prices. Apart from this, the Forced air systems have now become common in public buildings. Here, heated air is forced out through air ducts. They often have filters on them to reduce pollution. Another way is resistive heating by electricity. Here, conductive filaments which are laid down in floors or walls are heated with electricity. You can read our heat pump reviews page to find out more about heat pumps used in HVAC systems.

Air conditioning ensures that ventilation, temperature and humidity are maintained within a defined range. The system uses a refrigerant gas which is pumped to a high temperature and pressure. Several heat exchangers are used till the refrigerant changes into a liquid state. As this liquid evaporates, it uses up heat and therefore lowers the temperature. It then converts into gas and the cycle is repeated. All air conditioning system uses an evaporator to control the humidity.

Things to Remember About Heating and Air Conditioning Systems

The fact is that heating and air system does not come cheap. There is the cost of the unit itself, the specialized labor necessary to install the system and carry out periodic maintenance checks and the cost of energy. However, the advantages of the heating and air conditioning systems are:

  • The climate controlled atmosphere is most conducive to physical as well as intellectual activity.
  • Absence of such climate regulation leads to many diseases, especially in places of extreme climate. Hypothermia, stroke and hyperpyrexia can occur in such extremes of temperature.
  • An efficient climate control system also keeps infectious diseases, especially airborne germs, in check.

You should keep the following in mind:

  • Always install a ventilation system to ensure the supply of fresh air for greater air quality.
  • The outside climate, the size of the building, the number of users and the frequency of use will all determine the size and type of HVAC that you will need.
  • It is not enough to just install a system. You should ensure proper maintenance. Steps like replacing the filters timely can significantly reduce your energy costs.
  • Finally, take simple steps like turning off the system when you leave the house or closing the shades during summer. All these will help to increase energy efficiency, reduce costs and enjoy your heating and air conditioning system in the most environment friendly manner.
