HVAC System: What Is It, And How To Choose One?

HVAC is the acronym for heating, ventilation, and air conditioning. CVAC is a general term to designate the comfort of the indoor environment of all types of buildings, and the system responsible for the indoor air quality: air changes per hour, CFM (airflow, cubic feet per minute), temperature and humidity.

Similar to a standard building, the HVAC / HVAC system of a cleanroom regulates temperature and humidity at different levels of precision. The cleanroom HVAC / HVAC system differs from conventional systems by its increased air supply, the use of high-efficiency filters (HEPA / ULPA), and the pressurization of the room. The increased air supply generates more air changes per hour in order to bring clean air, filtered by HEPA filters, into the cleanroom several times every hour.

The design of the HVAC / HVAC system for a cleanroom involves knowledge of standards, characteristics of cleanliness classes, airflow, room pressurization, temperature, and humidity control as well as only indoor activities.

Tips For Choosing The Best HVAC System

If you want to be successful in choosing your HVAC system, you must take into account the following recommendations:

At the time of purchase, let yourself be advised by professionals on the type of equipment and the power it should have.

Choose a device that has a high degree of efficiency. This characteristic is indicated on the energy label of the same, which indicates the cooling capacity of the appliance, as well as its annual consumption.

When choosing an appliance, it is very important that it has adequate measures for the size of the home or room in which it is going to be installed. If it is too small, you will not be able to maintain the desired temperature. On the contrary, if it is too big, it can present problems when it comes to filtering the air, circulating it, or extracting the humidity. As a general rule, the larger the room or house to be refrigerated, the greater capacity the equipment must-have.

If you live in a city with low relative humidity, you will need an air conditioner with a power between 10% and 15% less than if you live in a humid city.

If your apartment is high or very sunny, the temperature will also be higher, so you will need a device with a 15% greater cooling capacity.

The construction materials, the orientation of our home, the design of it, and the number of electrical devices that are in it have an important influence on the needs of air conditioning and, therefore, are a decisive factor when choosing one or other devices.

The lighting inside the house is also one of the factors that increase the temperature, especially if it is halogen bulbs, which give off a lot of heat. If you have this type of light bulbs, you should buy an air conditioner with more cooling capacity.

The existence of technical service of the brand and a long warranty on the equipment are other factors to consider when choosing equipment.

Request several estimates in different specialized establishments, since the price of the installation may vary from one installer to another.
