Air conditioning installation
Air conditioner installation begins with the placement of the outdoor and indoor units of the air conditioner. As a first step in the installation, the two components must be connected with an appropriately sized insulated copper pipe in such a way that the closed-loop system thus formed can withstand the extreme pressure of the refrigerant after installation. The picture below shows the first step in the installation of a 10.5 kW air conditioner with four indoor units: connecting the units, building an electrical and drainage system.
Standard installation
The next step in the air conditioner installation process is the standard commissioning process. At this time, we test the closed system (our own work) with connecting copper pipes for the appropriate pressure or vacuum value.
We use nitrogen tank for pressure testing, and a vacuum pump for vacuum testing. During the commissioning of the air conditioner, we are assisted by a service valve equipped with two pressure gauges. With this unit, pressure testing and vacuum testing can be performed separately by operating the appropriate valves.
Maintaining the correct pressure and vacuum values for more than half an hour guarantees that the system will operate reliably and that there will be no refrigerant leaks in the part of the system that the installer has completed.
Importance of standardized installation
Air conditioner installation is an activity that requires professional qualifications and a permit. The electricity used to operate an air conditioner is much less than the heat energy generated indoors, so we can say that it is an economical and environmentally friendly heating and cooling option. However, the refrigerant flowing in the air conditioner is extremely harmful to the environment! The harmful effect on the environment occurs when the refrigerant enters the environment during installation or later due to improper installation. Currently used refrigerants do not damage the ozone, but when released into the environment, they have a greenhouse effect that is exponentially more harmful than carbon dioxide. One gram of the most common refrigerant, R32, is equivalent to 675 grams of carbon dioxide. When an average air conditioner is put into operation, approximately 1000 grams of R32 refrigerant are handled. It can be calculated that the air conditioning gas released into the atmosphere due to careless installation is equivalent to more than half a ton of carbon dioxide.
In order to comply with environmental protection considerations and to create a properly functioning, efficient device, it is necessary to follow the standard commissioning steps during air conditioner installation and to employ a registered installer trained for this purpose. After the vocational training, the National Climate Protection Authority deals with the allocation of refrigerant handling rights and the related education. The repairman qualification can be checked on the authority’s website.
