COMMERCIAL BUILDING HVAC SYSTEMS
Accepting your commercial building’s HVAC system is an imperative feature for many reasons, not the least of which is keeping the system whining along so you aren’t stuck sweltering in the summer when something goes wrong, estimate time and money. Today, we’ll enlighten some facts about commercial building HVAC systems, how they work, what to expect for upkeep, and more.
What is a Commercial HVAC System and How Does It Work?
Heating, Ventilation, and cooling systems, otherwise known as HVAC systems, are an essential part of modern buildings. HVAC systems are in charge of keeping temperatures contented (usually around 72 degrees), humidity dependable (between 40-60%), and indoor air excellence high (keeping C02 to less than 1000PPM).
There are several diverse types of commercial HVAC systems, but in general, these systems function equally:
- Air conditioning units lessen the temperature by transient air through refrigerant or water-cooled systems, also eliminating additional dampness from the air in the procedure.
- Heating systems fundamentally work in the conflicting fashion of air conditioning/cooling systems, where air passes through systems that heat the air using water, heater coils, or gas.
- Aeration systems keep the air clean by mingling air with fans and transient air through filtration systems.
If you’ve looked into auxiliary, repair, or upkeep of your buildings’ HVAC system, you’ll know that there are a devastating number of mixtures of different types of systems. While this is true, all of these numerous types fall into 3 main categories:
Single Split System
This is the most popular and reasonable type of HVAC system, found most usually in smaller commercial buildings. These systems allow separate control of the heating and cooling for each space, making it ideal for workplaces with server rooms or restaurants.
These systems characteristically include air conditioners that pass air by refrigerant lines and furnaces in one system that socializes air throughout the space via air ducts. The disadvantage of single split systems is that for each space you wish to control separately, you’ll need an outdoor unit – taking up precious space.
Multi-split systems operate correspondingly to the single split system but offer much higher energy competence and a much smaller outdoor footprint. Multi-split systems allow you to connect up to 9 indoor units to one outdoor unit. These systems also contain sensors that detect temperature changes and can adjust as desirable, intense far less energy.
Heat pumps in this type of system are also intended to move air in a way that works with the natural flow of warm air into cool areas, saving money and energy. These systems do necessitate more installation time, so the cost of installation can be higher.
VRF (variable refrigerant flow) or VRV (variable refrigerant volume) Systems
These systems are best for larger mixed-use type buildings, such as larger office buildings or hotels.
Heat Recovery VRF systems can deliver heating and cooling to different spaces at once, using warm air waste heat from areas of the building and bringing it to where heat is obligatory, particularly great for buildings with lots of smaller rooms. Heat pump VRF systems deliver either heat or cooling and are best for larger open areas.
What Kind Of Maintenance Do Commercial HVAC Systems Require?
Regular upkeep can keep your HVAC system working at its most effectual, keeping it humming along for its full life expectation – or beyond. Along with maximizing the lifespan of your HVAC system, proper regular preservation can lower energy costs, reduce the need for expensive repairs and downtime, and guarantee constant coziness for your customers and employees. Preemptive upkeep includes tasks such as:
- Spring and Fall system checkups that include:
- Cleaning and inspecting all outdoor mechanisms
- Refrigerant levels measured and recharged as needed
- Blower, belts, evaporator coil, and other indoor cooling system components are examined and cleaned
- Burner gatherings, ignition systems, and other indoor heating system components are reviewed and cleaned
- Control systems are tested
- Air Filters checked and changed frequently, according to the manufacturer’s recommendations
- Thermostat programming checked and reset seasonally
- Monthly visual examination of thermostats, drip pans, and drain lines
What are the different categories of commercial HVAC systems?
Building size can often regulate what type or combination of HVAC system works best to heat and cool it. Although there are differences, most can be pointed down to three main groupings:
- Single split system: Popular and reasonable, this system is often found in smaller profitable buildings and allows for individual heating and cooling control of each space. If it’s a workplace building with a server room for computer apparatus or a restaurant, this would be ideal. This system features a mixture air conditioner/furnace that passes air through refrigerant lines and socializes it via air ducts. However, for each space you want to control, it necessitates a distinct outdoor unit.
- Multi-split system: Up to nine indoor units can connect to one outdoor unit, after better energy competence and a smaller outdoor footprint. Sensors distinguish temperature changes and can be adjusted as needed. However, multi-split systems take longer to install and can be more expensive.
- VRF (Variable Refrigerant Flow) or VRV (Variant Refrigerant Volume) systems: These work best in large mixed-use buildings, such as big office buildings or hotels, where both heating and cooling of different spaces could be needed at once.
Many business owners know they need to get a new HVAC system, but they may have little information about HVAC. They might also have distress understanding the installation quotes or apparatus requirements they get from profitable heating contractors. If they follow a few strategies, they may be more self-assured when choosing a contractor and/or commercial HVAC system:
- Ask for a complete interruption of costs. When you talk to possible contractors, have them submit price estimates that cover all aspects of installation, from start to finish.
- Learn about the latest heating and cooling technology, system types, and manufacturers. Associate systems, costs, and benefits.
- Remember to comprise the cost of ductwork in your installation budget. Ductwork and piping can add a lot to installation costs, so you need to be inexpensive for them if you can’t use existing ducts and pipes.
- Budget for system controls, such as thermostats. Contingent on your building’s size, you could need dozens—or hundreds—of thermostat control points.
- Talk to your contractor about regular conservation. Getting a new system installed can be expensive, but not planning for regular upkeep can make it even more luxurious. Ask your servicer if they guarantee their parts and work and if they contain scheduled conservation services.
