Various Types Of Commercial AC Systems One Should Know About


Heating, ventilation, and air conditioning (HVAC) system is a must-have for every industrial or commercial home. The system maintains a comfortable interior environment for inhabitants by managing the building’s humidity, temperature, and air quality. Since HVAC systems account for around 40% of total energy consumption in commercial buildings, getting high-quality HVAC systems is critical. If your commercial AC unit has to be replaced, you should know the many types of HVAC systems available. There are three primary types of commercial air conditioning systems available.

Split Air Conditioning System

The split HVAC system gets its name from the way it comes together and the components that make it up. An interior unit, such as an air handler, an outdoor unit, the condenser, a programmable or non-programmable thermostat, humidity control or filter system, and ductwork, transports conditioned air from the system to the building, are all part of the system. Split commercial air conditioners have two categories: single-split and multi-split.

Single Split System

The single-split air conditioner is a low-cost commercial air conditioning system ideal for compact spaces like cafés, server rooms, stores, and offices. The compact system is simple to install, so it is ideal for new buildings or commercial spaces that need remodeling. It is less expensive to install, making it perfect for small commercial areas. Because each unit is self-contained, if one fails, the others will continue to function. Each indoor unit may supply air conditioning to only the rooms that require it. It’s the most acceptable option for a single room that necessitates using a separate HVAC system.

Multi-Split System

Multi-split systems allow you to link many interior units to a single outdoor unit. Larger venues, such as retail stores, physicians’ offices, and restaurants, typically have these systems installed. A multi-split system contains a lot of piping that must fit correctly. It occupies less space. It keeps your building’s outside looking good. The installation does not necessitate the presence of ducting in your building.

VRF or VRV System

A refrigerant is used as the heating and cooling element in the Variable Refrigerant Volume (VRV) or Variable Refrigerant Flow (VRF) system. Because it features a single condenser that one can use for many evaporators, this is the optimum system for usage in medium or large commercial areas. The refrigerant supply is controlled by an Electronic Expansion Valve (EEV) in each system’s internal components, ensuring that it follows the building area’s demand. These are excellent for business areas that are medium to large. They are simple to install in buildings that are undergoing renovations.

Systems for CAV and VAV

A Constant Air Volume (CAV) and a Variable Air Volume (VAV) system are two types of HVAC systems that work similarly. A compressor in the CAV system runs at total capacity until the building temperature is ideal. The system is excellent for commercial environments with long-term temperature stability, such as manufacturing and storage operations. It’s suitable for areas that need ventilation regularly.

The Variable Air Volume system is ideal for rooms that require changing levels of heating and cooling. The speed of the system compressor or fan changes based on the room temperature. The compressor also controls refrigerant flow to keep temperatures constant. As a result, the system is energy efficient. It saves money on energy and is appropriate for buildings with varying ventilation demands.

The best commercial ac unit for your building will be determined by the air conditioning requirements. The appropriate business air conditioner will give you the best value for the money.
