Heating and Air Conditioning Systems for Climate Control


Changes in climatic conditions may have drastic effects on the overall health of individuals and this explains the need for an effective heating, ventilating and air conditioning system. This can also be called as an HVAC system, which is a term used extensively in the industries today. Earlier, this system was used only by the commercial establishments, but now they are being preferred by home owners as well. The system can be used for domestic purposes, depending on the needs of the household. It can be installed with controls for regulating the climate at specific places inside the house or it can be a centralized air system.
The heating, ventilating and air conditioning systems have the required components to provide the right amount of heating during the chilling winters. Under floor heating is required for a larger living space as the temperature under the ground is higher as compared to the temperature above the ground. An air source heat pump can be effectively used for under floor heating. But before buying this pump, the size must be properly checked in order to make sure that it fits well in the intended space. The pump must have the required air flow for it to keep functioning efficiently.

HVAC systems also have an air conditioner that keeps a house warm during summers. The temperature inside a house rises during summers, making it very uncomfortable for the people to stay indoors. The system must have a perfect size in order to cool the house whenever the temperature rises. But today, these systems are equipped with software which calculates the required a
mount of cooling for the room. The air conditioning systems also have the devices that save a great deal of energy.

Air handler is a very important unit used for conditioning and circulating air inside a room. It is manufactured with different specifications according to its requirement. An air handling unit for a house is usually smaller than that which is required for a huge building. Thermostats are used to control the temperature inside a room with the help of heating and cooling functions. They turn on the heating devices when the temperature in the room falls below a certain level and cools when the temperature soars. There are different types of thermostats available in the market and can be chosen according to system requirements.
Energy consumption of a heating, ventilating and air conditioning system can account for almost half of the energy consumed by the house. Hence, the heating or cooling system should be used only in the rooms where it is required. Zoning facilitates the shutdown of heating or cooling system and allows users to set the temperature in the individual zones. Remodeling of a house is a great opportunity to install these systems. It is easier to fit equipments for the system when the renovation work is being carried out as the air ducts are more visible due to the tearing down of old structure.
