Modern HVAC Displays: Much More Than Switches And Thermostats

Do you remember those huge rectangular boxes outside and on top of your favorite supermarket buildings? These boxes are one of the visible parts of heating, ventilation, and air conditioning (HVAC) systems.

What are HVAC systems?

As mentioned above, HVAC or heating, ventilation, and air conditioning systems are used to promote indoor comfort. HVAC systems are utilized to be able to move and circulate air between indoor and outdoor areas to promote efficient heating, cooling, and ventilation of one’s home, vehicle, and even industrial and commercial establishments. HVAC also have filters to keep the air around you clean and fresh. HVAC systems promote satisfactory experience and provide cost-effective and efficient options for an optimal service.

How does HVAC systems work?

There are different types of HVAC systems that all specialize in what a client needs in particular and requires for what they are trying to set up. In general, HVAC systems will circulate air through ventilations. Ventilations can be natural, like through our doors and windows, or mechanical through the use of pumps, ducts, and pipes. Mechanical ventilation usually already runs the air through filters and directly run it through heaters or coolers before directed o the space where it was desired to go. Proper ventilation allows the removal of unwanted gases like carbon dioxide and carbon monoxide and to get it replenished by oxygen. Excellent ventilation also keeps the air clean and avoids foul odors and the introduction of bacteria and molds.

What are the modern HVAC systems like? Modern HVAC systems now use a lot more than just switches, pumps, and thermostats. Since adding LED screen displays in everything has been an ongoing trend, HVAC systems are now getting their own HVAC displays. Modern systems now have completely environmentally friendly equipment and use of chemicals unlike the harmful chlorofluorocarbons, also known as Freon, of the past days. Options of adding air-to-air heat exchangers are now also available which are studied to be able to provide fresher and cleaner air with no problems in energy efficiency. HVAC systems of today also employs the use of sensors, namely gas and pressure sensors in order to heighten efficiency while minimizing costs. This is also where the new trend of HVAC displays come in. The new displays can be connected in analog and digital sensors to optimize your HVAC system use. A wide array of touch screen displays are also available. These allow you to maximize ease of use of the systems while remaining efficient and cost-effective

Do You Need Variable Frequency Drives In HVAC Intalls?

VFD: The Remote Control of your HVAC System 

Heating up and cooling down your home is like a cool and amazing thing to do. Thinking that you can control the temperature depending on the desired mood you have is a big help to maintain a comfortable environment and will let you reduce the stress you have for the day. Your own HVAC system or “Heat, Ventilation, and Air condition” system is the one responsible for this. But did you know that these sets of systems will not that successfully work without the help of other components, and one of these components are the “variable frequency drives” or VFDs. So, what is VFD and how does it work in our HVAC networking?

Variable Frequency Drives or VFD is like a remote control of your television. This is a motor controller that drives an electric motor by controlling or managing the frequency and the voltage of its power supply. It is like a throttle of a car, and talking about the HVAC networking, VFD is the responsible for adjusting the speed of an HVAC fan or pump motor. The adjustment of the HVAC fan is needed to save more energy and at the same time, it can prolong the life of your HVAC system. Studies show that through the help of VFD, there is a significant energy save and it can lessen the operating costs while using the equipment.

Furthermore, VFDs are like guards that will check first the system and will make everything ready before heating up the equipment. They serve a soft start that eliminates initial power surge or mechanical shock due to switching the motor from off to on. To be clearer, VFDs have the capacity to control the ramp-up or ramp-down of the motor. In more sense, without VFDs, your HVAC fan or pump motor is either 100% on or 100% off, there is no middle ground. 

There are so many reasons why we need VFDs in our HVAC system. As mentioned above, it can save more energy and can prolong the life of your equipment. Also, we want to adjust the mortar speed because we need to convert the power in hybridization applications, and we also need to match the speed of the drive to process the requirements of the equipment. VFDs are not present for additional expense but to lessen your additional expense. 

If you are now already thinking about integrating VFDs into your HVAC system, consider the total cost of the HVAC and the additional cost of the VFDs and compare it with the potential energy save. There is a significant advantage for you.
