Commercial Building. Having a building that stays cool in the summer and warm in the winter — keeping your employees and clients comfortable year-round, is something you may take for granted. What is a commercial hvac system and how does it work? There are several different types of commercial HVAC systems, but in general, these systems operate similarly: Air conditioning units lower the temperature by passing air through refrigerant or water-cooled systems, also removing excess moisture from the air in the process.
Ventilation systems keep the air clean by circulating air with fans and passing air through filtration systems. WHat are the different types of hvac systems? While this is true, all of these various types fall into 3 main categories : Single Split System — This is the most popular and affordable type of HVAC system, found most commonly in smaller commercial buildings. These systems allow individual control of the heating and cooling for each space, making it ideal for offices with server rooms or restaurants.
Multi-Split System — Multi-split systems operate similarly to the single split system, but offer much higher energy efficiency and much smaller outdoor footprint. Multi-split systems allow you to connect up to 9 indoor units to one outdoor unit. The system compressor or fan speed varies depending on the temperature of the room.
The compressor also regulates the refrigerant flow to maintain consistent temperatures. This makes the system energy-efficient. The ideal HVAC system for your building will depend on the air conditioning needs.
The right commercial air conditioner will provide value for your money. Get a quote today! Common Types of HVAC systems There are three major types of commercial air conditioning systems available on the market. The system comprises of the following parts: An indoor unit, such as an air handler An outdoor unit, which is the condenser A programmable or non-programmable thermostat A humidity control or filtration system Ductwork, which moves conditioned air from the system to the building There are two types of split commercial air conditioners: Single-split Multi-split Single-Split System The single-split is an affordable commercial air conditioning system that is suitable for small spaces such as cafes, server rooms, shops, and offices.
Advantages Cheaper to install and, therefore, ideal for small commercial spaces Each of the units is self-contained. Therefore, if one breaks down, the others will still be working. Each indoor unit can be used to deliver air conditioning only to the room that needs it. The best solution for a single room that requires an additional HVAC system Disadvantages It occupies a lot of space as it has an outdoor unit for each internal unit Multi-Split System With multi-split systems, you can connect several indoor units to one external unit.
High-pressure liquid refrigerant is very warm at the time it first enters the expansion valve, so a precision valve improves overall system efficiency. The thermal expansion valve can be on either the inside or the outside of the air handler, screwed in front of the evaporator coil or brazed into the copper lines that link up to the air handler. Air Handler including Evaporator Coil and Blower.
The air handler is the component responsible for circulating air through the system. In most structures, it is connected directly to the ductwork. It blows cooled or heated air into the building and then returns it back into the system.
It includes a blower, heating and cooling elements, and a variety of other devices. Of all the different parts of the air handler, the evaporator coil is the one most likely to need maintenance or replacement. The evaporator coil holds chilled refrigerant received from the compressor. As air from the blower fan moves over the coil, heat is removed from the air in the treated area. Terminal Units. Terminal units consist of an air filter, coil, and blower. Size varies significantly.
They can be used to control temperatures in a single room. Chillers come in air-cooled and water-cooled varieties.
In an air-cooled chiller, the condenser coils are cooled by fan-driven air, with the unit usually found outdoors. Systems that sustain intense cooling for long periods of time are more likely to use water-cooled chillers.
