Carrier and the Inner Workings of Cooling

When it comes to air conditioning there is no other name more identified with HVAC cooling than Carrier.  Carrier has been a consistent leader in the HVAC market for many, many decades. This air conditioning giant has a worldwide impact on both HVAC quality and a focus on efficiency.  Actually, Carrier is far more than that. The company founder, Willis Carrier and some fellow engineers created what is today considered the air conditioning unit. This group of forward thinking people put air conditioning on the map.  And they did this in 1902.

The very first design for air conditioning was unveiled in upstate New York at the very turn of the 20th century. Mr. Carrier and his group pooled their savings to create the Carrier air conditioning company.  That company’s momentum took them to New Jersey where they opened the very first Carrier factory. This modern idea of cooling air became a pivot point for American industry as we know it. The arrival of effective air conditioning transformed the American economy.  Everything from food to manufacturing was completely changed. Air conditioning provided a fundamental fulcrum for the success of country’s economic power. Carrier is directly responsible for this seismic shift.

Only a few decades later, Carrier again created a market and revolutionized a landscape.  By the 1950’s, Carrier had innovated their air conditioning design to encompass the normal, everyday household. That decade brought air conditioning into our homes in an affordable package. This was groundbreaking due to how it would effect the American tableau. Parts of the country which had been previously thought vacant were now beginning to see sprawling communities popping up.  Entire regions of America were now not only accessible but desirable. Population growth exploded south and west due to the advent of residential air conditioning. Again, this is directly due to the innovation and influence of Carrier. With that growth came a continued development of the air conditioner.

Within decades, what we consider to be the modern air conditioner was born. Now, one can find the central air or Split style air conditioning unit nearly everywhere experiencing  sustained high temperatures. The Split style air conditioner is nearly ubiquitous now. But what is central air and how does it work? Central air or the Split systems are basically HVAC units which have a cold side and a warm side. The cold side of the modern HVAC unit consists of an air handler, fan coil and the evaporator coil. I think we all know where the air handler unit is within our home. But this is only half of the air conditioning system. The warm side is the equipment which sit outside the home.  This side of the Split system consists of the compressor and the condenser coil. These two integral parts are housed, along with a large fan, in the metal cabinet resting on a concrete pad outside your home. The warm side and cold side are connected by copper tubing with refrigerant in them. They work in conjunction to provide cool comfort inside your home. It all starts when the thermostat senses the air needs further cooling. The thermostat sends a signal to both the inside and the outside units to begin working simultaneously.  The fan inside the air handler starts pulling the indoor air through the return duct. This fan then blows it across the cold evaporator coil. The liquid refrigerant inside that evaporator then turns into a gas. In this form it is able to absorb the heat from the inside air. This air is cooled by the coil and then transferred into the home by a blower fan. Now, that refrigerant which is still in a gaseous form then leaves the home for the outside unit via copper tubing. At this point, the refrigerant goes into the compressor where it is then pressurized and sent to the condenser coil so the heat can be released to the outside air.  While all of this is going on, that refrigerant then turns back into liquid form. From there, the liquid refrigerant travels again through copper tubing back inside to the other half of the system. Finally, the refrigerant goes through an expansion device which regulates the flow of refrigerant back into the evaporator coil where it all started.

The cycle begins again and continues until the desired temperature setting is met. Modern air conditioners work by removing heat and humidity from your home. Residential units don’t simply blow some sort of canned cool air. There is a very precise mechanical process which relies on physics and nature.  Carrier has continued to find a more efficient and planet friendly way to deliver the cooling process for residential comfort. An example of that type of innovation can be seen in Puron refrigerant. This no simple Freon type of refrigerant. That would be an insulting comparison. Puron refrigerant is referred to as R410A. It is far and away more eco friendly then Freon or R 22 refrigerant which will soon be completely phased out in the United States. Carrier has been the industry leader in the transition from R 22 to R410A. Carrier has displayed a corporate responsibility with it’s dedication to the more environmentally conscious Puron refrigerant.  They have done so here in the United States and around the globe. Carrier’s Microtube technology is another example to the importance of efficiency. Again, through constant innovation, Carrier has been able to reduce the size of copper tubing thus reducing the amount of refrigerant. The less refrigerant used, the less waste and increased energy efficiency. Carrier makes one of the smallest copper tube-aluminum fin technologies available. This also allow for a reduction in size of the overall air conditioning unit. Carrier’s core values are on display throughout their entire line of air conditioners. Every Carrier air conditioner is a quality product that is reliable and consistent.  Carrier will continue its great tradition of bringing care and comfort to its customers through a winning combination of technology and innovation. Carrier is the HVAC industry leader for a reason.
