What Are the Different Types of HVAC Systems?

Many people are underestimating the value of HVAC systems and they fail to realize that these systems are a luxury feature which can increase the value of their home. Just think about it for a moment without effective heating, air-conditioning and ventilation people soon begin to appreciate these comfortable systems, it is just so unfortunate that a large number of people do not take proper care of their HVAC systems which leads to unnecessary breakdowns. Many people are also poorly informed and in many cases, they are unable to tell you which specific HVAC system they have installed. The HVAC systems which are encountered in most family homes can be categorized into three basic types such as those providing ventilation, air-conditioning or heating. When you look at those HVAC systems which are specifically installed to provide heat then they basically consist of a forced air gas system, a pulsing or condensing furnace, a heat pump, and it may have an electric or gas hot water radiant system.

HVAC for ventilation

These systems often have a variety of indoor fan units, ceiling fans and exhaust fans which is situated mostly in the attic. There are several different units such as multi-zone, single zone, and double ducts also exhaust fans and the system will also have constant air volume boxes which allow for reheating. As far as air-conditioning is concerned there are window units, central air split systems, evaporative cooling systems, and wall-mounted split systems. They function with cold water and direct expansion room units and in some cases rooftop direct expansion. Air conditioners are in most cases central air types which makes use of exterior and interior units which has been fitted with special components.

Configuration

Users should know that the primary functioning and features of most HVAC units are that such systems are often connected to each other by using specially manufactured power cables and there will also be lines which are used to spread coolant through the system. Such coolant will continue to circulate through the lines of the unit and this results in a situation where gas is converted into liquid and also back to gas. Furthermore, these systems are fitted with an evaporator where the liquid coolant is converted into a gaseous state and in this condition, it will absorb heat while at the same time producing constant cool air. That coolant which is now in a gaseous state will proceed to the condenser where it will be converted back into a liquid form. Every time the coolant is in liquid form it will release heat which will then be dispersed into the air outside your home and this process will be repeated again and again ensuring a consistent temperature inside the family home.

Effective furnaces

HVAC systems is also excellent furnaces and in such systems the fuel which is required for the process is provided by means of an on-site storage tank that will have to be filled up from time to time by a fuel supplying company but in some cases it will be fed by the supply lines coming from local utility companies. When it comes to HVAC furnaces consumers often prefer the electric variants even though they are somewhat more expensive to operate because they function by producing heat via energy-hungry heating elements which will become very hot as electrical currencies pass through those elements. Another popular HVAC system is air source heat pumps which is often used in residential properties and which also works on the process which involves a refrigerant or a coolant.

Air Source Heat Pump

Air Source Heat Pump

Nevertheless, heat pumps function by capturing available heat and then moving that from one place to another. As the heat continues to be produced the outdoor coils will function as an evaporator. However, when cooling is produced the indoor coils will now function as they evaporate and in this way, the flow of the refrigerant is reversed.

Additional facts

During the continuing cooling operations, the coolant turns into a gaseous state while indoors because it is absorbing the heat which has been circulated outdoors where the excess heat has been released. This is a cycle which is repeated over and over again in order to ensure the optimal functioning of these highly efficient heat pumps. As people can see there are many systems available some of whom will be a perfect solution for your family home. Nevertheless, it can be helpful to speak to a professional who may be able to come to your home in order to professionally evaluate your particular needs and then to advise you on which type of HVAC system will be most effective for use in your family home.
