How Does an Industrial Air Handler Work?

The industrial air handler is an integral part of most industrial HVAC systems. Also known as an air handling unit, this device is responsible for the circulation and regulation of air through the HVAC system. Particularly because of its importance to the overall system, you may be curious about how your HVAC system’s air handler works. Before getting to know the process, it can be helpful for you to learn the terminology and types of air handlers so that you can better understand the unit that you use in your facility.

Your facility’s HVAC system most likely has a large outdoor air handling unit. These are commonly referred to as packaged units (PUs) or, when located on the roof, rooftop units (RTUs). Both of these are also called makeup air units (MAUs), as they only condition air from outside the facility rather than recirculating the air from inside. Air handlers that recirculate indoor air are known as terminal units. These are generally smaller and are only used in localized areas.

The Air Conditioning Process

The easiest way to explore how your air handler works is by examining the route that air takes through the various components of the whole unit. For most larger systems, this process is as follows:

  • Return fans bring air in from the return duct through air filters to prevent dust and other impurities from traveling through the system.
  • Heating and cooling elements, which may involve direct or indirect heat exchange methods, then condition the air to the desired temperature.
  • A humidifier may be present in colder areas to help prevent heating units from drying the air too much during the conditioning process.
  • In temperate climates, air is often moved to a mixing chamber, where return and exhaust air may be mixed to more accurately reach the desired temperature.
  • Supply fans will then blow the air back into the facility through the supply duct.

 

Not all industrial air handlers are made the same. Depending on the size, type, and other factors of your facility’s air handling unit, you may notice different or additional components. You can always talk to an expert if you have additional questions about the inner workings of your industrial air handling unit.

Find a Company That Has a Lot of Experience

Look for a company that has been in business for several years at least. Don’t make the mistake of selecting a company that has a mysterious reputation, either. A good track record means everything in the air conditioning repair world. Select a company that gets fantastic and consistent reviews from customers. If you’re looking at a repair company and keep reading reviews that mention careless technicians, poor customer service and outrageous rates, stay away from it. If you’re looking at one, on the other hand, and keep seeing reviews that talk about prompt service, first-class equipment and courteous team members in general, you should give it more attention.

Focus on Pricing

Pricing isn’t the be-all and end-all in the air conditioning repair realm. That’s not to say that it isn’t an important factor, however, because it is. It’s critical to find a company that offers excellent value. Be wary of companies that give you quotes that are unbelievably low. Their prices may actually be too good to be true. Steer clear of companies that give you quotes that are outrageously high, too! There’s no need to spend an arm and a leg on repair work. You need to choose a company that offers fair, reasonable and competitive prices. It’s also vital to choose a company that offers written quotes.

How Building Automation and Controls Can Save Your Company Money

Remember when building automation was the domain of science fiction and cartoons? While we aren’t quite up to that level, yet, building control has come a long way. We’ve got everything from smartphone apps to control your air conditioning and lights to complete systems for building automation. In fact, not only can you deploy building automation and controls, it can save your business some money.

 

Electric and Gas

Energy usage in commercial buildings is coming under more intense scrutiny every year. It’s not surprising since those buildings waste around 30% of the energy they use. Advances in sensor technology and cloud computing make building automation and controls a viable alternative for saving on energy costs. With the right setup, your building will automatically adjust heating, cooling, and turn off lights. Taken together you can expect to see a significant lowering of your energy costs.

 

Improved Productivity

Air quality plays an important role in employee health. Improved air quality has been linked to better cognitive performance, reduced illness and fewer headaches. All of which improve overall employee productivity. Building automation allows you to optimize air quality and ventilation during working hours. This reduces employee absences and boosts productivity related revenue.

 

Extend Equipment Life

A nice side effect of raising or lowering the temperature in your building during off hours is that it extends your equipment life. Reducing the total number of times the equipment needs to cycle on and off in a day means more time before the equipment needs to be repaired and replaced. Similarly, lights bulbs have a relatively fixed life. Turning them off during non-working hours not only saves electricity, it extends the working life of the bulbs.

 

Preventative Actions

Depending on how sophisticated your building automation and controls system is, it can warn you when things start going wrong. Everything from notifications when a bulb burns out to alerts when equipment fails. Some systems even use machine learning to gauge when equipment needs servicing based on changes in performance. Catching a problem before it turns catastrophic can often mean the difference between an inexpensive repair and a very expensive replacement.

Building automation is a money saving investment. It lets you reduce energy costs, improve productivity and extend equipment life. It’s also a good PR move. Making your business greener is something many potential customers like to see.

Things To Check Before Calling a Local Air Conditioning Repair Company Near You

Summer is the hottest season of the year. Moreover, other parts of the country are hotter than others during this season. For this reason, the last thing you want is to have the air conditioner in your house blow you with hot air. While an average AC unit can last for about one decade, this does not necessarily mean that the air conditioning system will not require maintenance or repairs that are performed by a local air conditioning repair contractor. It is our shocking realization that only 42 percent of people who use the central air conditioning system service and maintain it regularly. For this reason, be sure you are not one of those people who get stuck in heat during the summer season.

Are you in the right direction by calling in a local air conditioning system repair company? In some occasions, you may never need to get the services of an air conditioning contractor to get the services working normally again. You can learn how to conduct some troubleshooting experience by yourself by checking the three things below.

The Programmable Thermostat

In the first place, you should consider checking your air conditioning system thermostat. In many occasions where the air conditioning system breaks down, the only thing you need is to replace the batteries with new ones. As a general capability, you should consider changing your batteries for the thermostat every time the summer season is near to prevent the air conditioning system from breaking down.

The Air Filters

It has been said on numerous occasions. However, it has never been stressed enough. Your air conditioning filters must always be changed more often than not. In the real sense, these filters should be replaced after every three months. They should also be replaced regularly during the summer. Replacing new filters cuts down the energy consumption of the system by over 10 percent.

AC Circuit Breaker

Lastly, your air conditioner circuit breaker should be checked to see if it is tripped. If you trip the breaker, be sure to look for an AC repair. This is because they mean that the air conditioner might have overheated. During these times, never try switching the AC back on. Seek the help of a specialist to handle the issue.

After inspecting your air conditioning system for issues and it does not run efficiently, it is now time to call in the company professionals.

Commercial HVAC Services in Silicon Valley

HVAC services are important all year round, especially in the summer, for Silicon Valley businesses. Records show some summer temperatures recorded as high as 105°. This makes commercial HVAC’s having to work overtime to maintain a reasonable temperature for their customers. As a result, it is extremely important to keep the HVAC working at its highest efficiency at all times.

Choosing the Right HVAC

There are a number of HVAC units on the market today with a wide assortment of sizes and prices. Having the right size for your establishment will assure that the proper amount of warm or cool air will automatically turn on when required.

The choice of the size of the unit needed, for your particular establishment, should be determined by an expert HVAC technician. The square footage of the amount of space to be cooled or heated, the number of ducts required, the location of controls and other feature are involved.

These units can vary in price from $2,500 to $12,000, or more, depending on the size of the building. Each unit has specific features, which should be understood prior to purchase. You should always insist on a unit that meets the Energy Star® regulations. Units meeting these requirements have money saving features.

As a rule, the company that sells you the HVAC unit also does the installing. All costs, regarding the price of the unit and installation, should be provided in a free estimate, by the HVAC Company, at the beginning of the transition.

Installation

Once you have had a trained HVAC expert chart out your building, he or she will be able to tell you the number of BTU’s that are required to provide adequate heat and cooling to your building. They will also determine location of registers and ducts. Care should be taken in the location of the controls. Larger commercial buildings usually have these controls located in more than one place.

Maintenance

Once the unit is installed and working correctly, it is important to have a yearly maintenance check. This will help avoid unexpected breakdowns, which can be a disaster in a retail establishment. One of these maintenance jobs is cleaning the ducts.

Many people do not realize that ducts can accumulate dust mites, pollen and other things that can cause problems with customers or employees who suffer from allergies or other breathing problems. HVAC experts should clean these ducts at least once a year to avoid this situation.

When contracting with an HVAC Company it is important to determine their guarantees, emergency service, insurance, bonding and affordable pricing. This will help avoid any misunderstandings later.
