Mead Commercial HVAC Replacements

There are three primary types of commercial HVAC systems on the market. Each unit has its own advantages and choosing the right system for a particular building is an important aspect of any commercial HVAC installation. 

The three main types of commercial HVAC units include: 

• Split HVAC system – A split system is made up of several components, including an indoor air unit (air handler), an outdoor unit (condenser), a thermostat, a filtration or humidity control system, and ductwork. There are two types of split HVAC units: single-split and multi-split. The single-split system is easy to install and suitable for small spaces such as shops, cafes, offices, and server rooms. One disadvantage is that each internal unit requires its own outdoor unit, which causes it to occupy a lot of space. A multi-split system, on the other hand, takes up less space since one outdoor unit can be used for several indoor units. Multi-splits are more costly and take longer to install, and they are usually found in larger spaces such as restaurants, doctor’s offices, and retail shops. 
• VRV or VRF system – The Variable Refrigerant Volume (VRV) or Variable Refrigerant Flow (VRF) system heats and cools using a refrigerant that is controlled by an Electronic Expansion Valve (EEV). This system has one condenser that can be used for multiple evaporators, making it ideal for medium and larger commercial properties. The two main types of VRV systems are heat pumps, which are more efficient for open spaces, and heat recovery systems, which work great in commercial buildings with several rooms. 
• CAV and VAV systems – The CAV unit uses a compressor that runs at full capacity until the appropriate building temperature is reached. This system is a great solution for properties where temperatures remain constant for long periods such as warehouses and manufacturing facilities. A VAV system is best suited for spaces that have varying heating and cooling needs. The compressor or fan speed of this energy-efficient unit varies based on the temperature of the room, and it offers superior control of temperature and humidity.
