How Does a HVAC Operate in a Large Building?
The heating feature of a commercial HVAC system is supported by radiators or supply air systems that are housed in the large building.
A commercial HVAC system installed in a large building has interconnected systems that offer heating, ventilation, and cooling to all needed areas of the building. Such a system will have a heat pump, which extracts heat from air or water to do the heating. A heat pump with a water source will have a pipe that carries water around the building. A roof top unit is usually installed on the rooftop but can also be on the ground. This unit works to put purified and conditioned air into the large building. Heaters in a large building are of two main types – furnaces, which burn fuel to heat air in the building and radiant heaters, which use infrared radiation.
Types of HVAC Systems Used In Large Buildings
A centralized HVAC system is one unit that is located in one area, which supplies the heating, cooling, and ventilation needs to the building. This system uses water as a medium for cooling and has a good amount of ductwork that is used for air distribution. One benefit of using this type of HVAC is that it is able to handle a higher load and is quite easy to control. This makes it quite fitting for use in a large building. The only downside of a centralized system is that it can be hard to install and maintain.
A packaged HVAC contains a heat pump and an air conditioner together with the fan coil and evaporator in one single unit. This kind of system is quite common in a building that does not have a lot of extra space to house the separate parts of the system. A packaged HVAC has a thermostat, which works to control the system plus optional features such as purifiers, ventilators, and air quality boosters.
Also referred to as a decentralized system, an individual HVAC offers heating, cooling, and ventilation through multiple individual units in different areas of the large building. This system is quite easy to control. Examples of individual systems include roof top units, air-to-air heaters, and AC units for office and rooms. It is good to note that this system is not highly preferred for very large buildings.
What Kind of Maintenance Does a HVAC System for a Large Building Require?
Regular maintenance can help keep your HVAC operating efficiently along its full life expectancy. Apart from making use of the maximum life expectancy, regular maintenance can help reduce cost of repair, lower energy costs, and ensure constant comfort to your clients and employees.
To ensure your HVAC system is operating optimally, be sure to clean and inspect it regularly, test control systems often, have belts, blowers, and indoor cooling systems checked for issues frequently, and ensure refrigerant levels are recharged and measured as needed. These are tasks that you might not be able to do by yourself and that is why you want to work with HVAC experts to do regular checks on your HVAC.
Having a building that stays cool during hot days and warm during cold days can be quite beneficial for your employees and clients. This is because they will always feel comfortable to conduct business with you. This is something that should not be taken for granted. To achieve this, you need to make use of a HVAC system. The only HVAC system fitting for a large building is what you would refer to as a commercial HVAC. This article has shown you how a commercial HVAC system operates so you can be well informed. If you still have some questions, be sure to talk to a qualified HVAC system expert.
