Heating Air Conditioning Units Explained
Contrary to the common perception that, air conditioners are only for cooling the air, conventional models now also condition the air by heating it up. So we do not only need air conditioners in sweltering seasons but also in the cold days such as in winter.
Climate controllers that are used during cold days are called heating air conditioning units. Typically, these are also central air conditioning systems that have split system. They have a compressor bearing unit located outdoors and a unit coil installed on top of the furnace indoors. The main component of heating air conditioning units is the furnace.
As we all know, the furnace operates to keep the room warm during the cold days. Furnaces also play a vital role in the operation of an air conditioning system.
The processes involving heating air conditioning units involve the furnace producing heat via the combustion of natural gas in its burner. This results in heat which then passes through the heat exchanger. As the room air moves to the air ducts, it blows over the heat exchanger pushing the heated air to the ductwork, and the ductwork then carries this air dispersing the warmed air throughout the room. During the warmer seasons, the same processes happen but the result is cool air.
Sometimes, the unit is also called a heat pump as it is used for heating or cooling by transferring heat between two reservoirs. During the warm season, it removes heat from room air and transfers it outside; during the cold days, it extracts heat from outdoors and transfers it to the inside.
The benefits of heating air conditioning units are many. First and foremost, it provides indoor warmth any time it is needed. Just like cooling air conditioners, they are also energy efficient. But these heating air conditioners do not utilize Seasonal Energy Efficiency Ratio; instead they use Annual Fuel Utilization Efficiency. Currently, the minimum standard efficiency level for furnaces is 80% AFUE. This standard rating offers great pocket savings as it means that for each dollar you spend heating your room, 80 cents are actually applied to the generation of warmth. The higher AFUE is better, so for enhanced energy efficiency, try considering a furnace with an AFUE of 95%.
Since it is a split system type and that the compressor is located outdoors, the indoor noise is minimized and it so provides a quieter operation.
Moreover, heating air conditioners also provide cleaner air. After drawing air and humidity out from various rooms, the heating, ventilation, and air conditioning system pulls the air through its filter. The sophisticated filter screens out airborne particulates such as lint, dust, and microscopic pollutants. The cleaning process is further enhanced with a variable speed furnace, because this uses variable speed blowers that shift between several speeds. Variable speed furnaces run longer at a low speed, which enables them to filter the room air more frequently. This type of furnace is also essential in cooling air, such that it helps maintain both a consistent indoor temperature and improved air quality all year round.
