In most commercial buildings, HVAC systems cool, heat, and ventilate every floor, both through a centralized system or independent units installed in individual offices. Without these, your high-tech, high-rise building wouldn't be very comfortable in the summer, chilly in the winter, and inconsistent in quality from floor to floor. With all these functions, there are also different types of HVAC for different purposes. When looking into HVAC, make sure to know the types of units and the facilities they provide.
The first type is the radiant heat and air conditioning (RHA) units. These are used in areas where there's usually a need for controlled temperature, such as in high-rise buildings. They are typically vented to the outside through ducts, or are installed directly to the exterior. They provide a cooler indoor air through their air vents while circulating warm, outside air to other areas. You might find this type of HVAC used in places like hospitals, industrial companies, or any other business requiring controlled temperature.
Another types of commercial HVAC is the multi-split systems. These are vented into more than one area. For example, in some types of HVAC, if you need the air to be able to go to the outdoors, you can install outdoor vrf units in various rooms, but you'll have an outdoor air conditioning unit in each room. Multi-split systems provide all the benefits of indoor vrf units, but with the convenience of being able to operate them independently. Some of these are installed as an independent unit from inside the building, while others are installed as an outdoor unit on top of or near an existing structure. The outdoor units have the same benefits of the indoor units, such as insulation and climate control.
There are commercial HVAC systems designed especially for high-rise buildings. Some commercial buildings may have more than three stories. In such cases, it is necessary to have multiple vents in order to provide complete air circulation within the building. This is also very important to control temperature in high-rise buildings. If the temperature in any area of the building rises above 100 degrees Fahrenheit, the occupants could suffer serious consequences.
One type of HVAC system is the single-split system. These are designed for single-story residential homes and for use indoors as well. While they provide the benefits of indoor and outdoor air flow, they cost less and take up less space than multi-split units do. A single-split indoor unit can be installed in a single-story home or on a two-story building, while a multi-split outdoor unit can be installed on a multi-story building or any higher structure.
As you can see, there are many different types of HVAC systems for commercial buildings. You need to consider the space you have, the heating and cooling needs, the number of air conditioning units and fans, your budget, the aesthetic appeal and the maintenance requirements of your system before choosing one. Your local HVAC contractor can help you determine which system will best fit your needs and your budget. You should also discuss the installation options with your contractor in order to get the most efficient system possible.
