When it comes to the concept of air conditioning, people often assume that it's only something that is related to cooling the air and temperature. However, you should know that air conditioning is more than just cooling the temperature. With the current technology today, you should be aware that air conditioning systems can both heat and cool the air. It's also called the HVAC system today.

You should know that the year 1902 marks a significance when it comes to HVAC application since it was first installed in the New York Stock Exchange building. The success of the HVAC system made it popular ever since. After that, the models have been developed further and was made to run on electricity. As a result, the air conditioning system became capable of having enough power to control the humidity. For more useful reference regarding Air Conditioning Repair, have a peek here. 


The feature to control the humidity basically made the air conditioning system something that's very useful for many kinds of industrial products. In addition to that, the performance of the employees improved ever since the modern air conditioning system was installed in the workplace. Of course, the air conditioning system has been developed further after some decades. This allowed its installation on homes and automobiles.


Having a refrigerant is something that's significant when it comes to having a working air conditioning unit. If the air conditioning unit has its refrigerant, then it will be used to alter or change the temperature of the air. There are things that you should be aware of when it comes to having your own air conditioning unit. You should know that air conditioning units before usually had harmful gases such as ammonia and methyl chloride as the initial refrigerants. Still, the air conditioning was improved and the chemical that's called Freon has been used as replacement for the harmful gasses.


The Freon chemical is safe for human beings. While it's certainly safe for humans, it's a fact that it can be something dangerous to the environment. Having that in mind, this chemical is known also known as a chlorofluorocarbon gas which is one of the responsible gases that thins the ozone layer. This is why research is still going on to make sure that the removal of the harmful chemicals that's affecting the surrounding environment  will be complete. This information will be of great help to you if you're planning to get the air conditioning unit that you need.


The cycle of refrigeration actually depends on the kind of air conditioning unit that you will be getting. Some modern air conditioning units today use heat pumps to drive out the hot air from the room or space and then lowers the temperature by making use of its built-in compressor. Then there are the units that actually makes use of refrigerants. The refrigerant basically evaporates the hot air with it and only leaving the cooled air.
