How Many Types Of HVAC Are There?
The HVAC sector is vast, in terms of the different types of commercial sector organisations it needs to service and their differing needs.
This results in systems being designed with different performance criteria, but the common denominator – whether the business needs heating, cooling or ventilation – is that the system has to be good value, practical in terms of installation and operation, and efficient.
Businesses have different objectives and targets, but most KPIs in modern organisations are based around managing costs of varying sorts and achieving environmental targets. Controlling these outputs is the principle design objective of most HVAC systems, but you still need to choose the right system to suit your operations, your buildings and your business. In general, therefore, HVAC systems are broken down into four basic categories:
These are possibly the most common systems, and a variant of these are found in many commercial organisations. A split system effectively means you have a unit inside and a unit outside, with air being circulated then by a system of ducting and vents. Split systems typically carry lower operating costs and are energy efficient. However, installation can be complex because of the need to join the two units and install the ducting in often challenging locations, and therefore a bespoke design is necessary. Typically a split system will have an outdoor unit such as a condenser and an indoor unit which carries out the heat exchange.
Hybrid split system
In principle, this is a more advanced version of a split system, because it uses an electric heat pump to power the unit rather than a traditional fuel, such as gas. This makes it even more energy efficient. The rest of the system is largely the same as a traditional split system.
Usually these will comprise of individual wall-mounted units in each room, linked to an outside compressor. These are even more efficient than split systems because the lack of ducting means there is no air loss and the system is able to react better and faster to temperature needs. Furthermore, the user has more control over this system, as unoccupied rooms can be turned off when no temperature control or ventilation is required. Installation is much quicker because the individual units are not linked by ducting and operation is also noticeably quieter. A ductless system can be used in individual rooms, but also as a supplement to an existing split system.
This is used for heating, ventilation and air conditioning in businesses where there is limited space. As the name suggests, all the components of this system are stored together in one unit, which is located outside. This is a great system for space-saving and installation, but it does leave the unit vulnerable to damage and extreme weather outside.
