  • Commercial and Residential HVAC System Comparison

    Commercial HVAC System Commercial HVAC System

    There are a wide range of HVAC systems, but the two main ones are commercial HVAC system and residential HVAC system. Residential systems are used in people’s homes and commercial systems are used in major retail stores, warehouses, office buildings, and other large buildings.

    Both Systems

    Both of these systems have similar functions such as ventilation, heating, and cooling. However, they do have just a few differences such as:

    • Size
    • Power
    • Drainage
    • Location
    • Complexity
    • Manufacture
    • Features

    There are HVAC companies that do specialize in commercial and residential systems. There are others that only specialize in cooling systems or heating systems. This will help to explain the reasons for the services being different. Some of the differences have exceptions, but they are mostly the same. Let’s take a closer look.

    The Complexity

    Due to the size and complexity of the commercial HVAC system, it has to be installed on the building’s roof. The reason is to ensure adaptability and space. The type of commercial system chosen will depend on various factors such as the number of occupants in the building, the varying temperatures, scheduled events and the number of hours the business operates. Other factors include items being sold, type of inventory, and number of windows in the building.

    The Size

    Of course, the commercial HVAC system is going to be larger than the residential system. This is a visible difference and the reason is that one heats and cools a larger space. So, the size will be different between the two and so will the power. The thermostats and dampers are also different in size and scope.

    The Location

    Residential HVAC systems are usually found at the side of a house. In some cases, you may find it in someone’s backyard. On the other hand, commercial HVAC systems are located in either swamp coolers or roof of a building as mentioned before. The roof tends to be the most common installation area chosen by most HVAC contractors. Why? Here are some reasons:

    • The indoor space is needed to conduct business in a commercial aspect and so a large HVAC system would only take up too much indoor space. It also can be less attractive if placed inside the building and more importantly, it functions better when installed on the roof
    • A commercial system would be too noisy and could be a disruption to business
    • It is easy to maintain on the roof. HVAC technicians can do repair and maintenance work without disrupting the business day
    • Vandalism and damages will be at a minimum because of less traffic on the roof where the commercial HVAC system is located

    Conclusion

    It is important to have a HVAC contractor to handle the maintenance of your air conditioning unit or heating system. It is still your responsibility, however, to make sure that you call a professional when it is necessary and before any malfunctioning occurs.

  • HVAC System Design for Commercial Installation

    HVAC Systems HVAC Systems

    Did you know that your heating and ventilation and air conditioning system provides your home with about 30% energy? This is common for small offices and residential homes as well. When you have a well-designed air conditioning system, it does adequately cool a building, but it also reduces the energy consumption. In addition, it also improves the building’s air quality without causing any damages to the environment.

    Industrial and Manufacturing

    In a manufacturing warehouse or industrial building, the HVAC system has various combinations of devices for heating and cooling. Some of these devices include:

    • Electric heat
    • Heat pump
    • Rooftop unit
    • Furnace
    • Chillers
    • Boilers
    • Central AC units

    For the commercial HVAC system installation, there are various system designs to choose from. For this reason, the installation should be done by an HVAC technician with industrial installation experience because some of these designs can be complicated while others are simple.

    Industrial Plant

    In the industrial plant, a basic system would be utilized in a single zone. Modifications are made when necessary to offer coverage to multiple plants or other large areas. For the basic industrial system, the air comes in from the air intake feature, which is usually found on the side or top of the building. Through atmospheric pressure, the forced air goes through a damper. The air is regulated to take in the amount that is required to cool the building. The air that previously went through the HVAC system will subsequently join with the external air.

    The Combination

    This combination is then filtered through the air filter, removing any large particles in it such as bugs, leaves and dust. After this, there is a second filtration process that handles the smaller particles prior to going through the fan. Once the air comes through the fan, it is then cooled or heated by the coils. If there is any condensation, a drain pan does the collection from the coils. The air then goes through the air duct to heat or cool the building, after which it returns through the air registers to be combined with newly created air or it goes out the building.

    Conclusion

    A basic HVAC system offers comfort to a specifically small space while a commercial HVAC system covers a wider space and has elements that consist of:

    • Packaged units
    • Window units
    • Heat pumps

    You will find a commercial system with evaporative coolers, chilled water systems and direct expansion coolers. So, if you own an industrial plant and need to have your HVAC installation done, the complex nature of it will require an experience and specialized HVAC technician. With a bad HVAC installation, you can end up paying higher cost in energy and have terrible air quality.
