The commercial air conditioning unit is responsible for the cooling of the big buildings which will in most cases be used for commercial purposes. They are the kind of system which will be responsible for the cooling of the big buildings which will have bigger rooms to be cooled. They will be used to bring the cooling effect to such buildings which will have many people will be moving in and out of such buildings. In terms of the functioning principle, the big commercial units will be similar to that of a residential ac where it will work using the same principal of a refrigerator. It will be responsible for the drawing of hot air from the big building and in exchange, it will bring in a cooling effect. These commercial systems will certainly come at a higher cost as they will be much bigger than the residential ones. Their installation too will require very qualified and experienced contractor to see to it that the system has been installed in the best way and that it is able to give the services it is meant to give.
There are some common components which will be found in commercial ac units. One of them is the compressor which will be responsible for the reducing the high pressured refrigerant to a lower pressure and volume. It will compress the gaseous state and send it to another component which is known as the condenser. It is the condenser which will be responsible for the converting of the high pressured gas into the liquid state. After the refrigerant has been converted to the liquid state, it will be moved to yet another component which will be metering devices. This one will be responsible for the determining of the amount of liquid which will be allowed to pass.
There will still be the evaporator coils which will be responsible for the distributing of the cool air to the entire building through the system of the duct work. There will also be another very important component which is the air filters. They will be responsible for the removing of the dirt and any other contaminants from the air. They will be rated and the high the value the more the ability the filter will have to remove more dirt and pollutants. Of all these components, the filters will need to be cleaned on a regular basis for it to be efficient.
