Are Rooftop Units The Most Efficient Type Of HVAC System

Self-sufficient heating-pump unit and air conditioning system are the two most popular cooling technologies in the United State’s commercial building facilities. The system is mostly installed on the rooftop and comes with high energy efficiency. The rooftop units are also known as the package unit, or air conditioners are machines produced in large numbers. These machines include air-handling fans, cooling equipment, electric or gas heating equipment, and more. The sizes of the RTUs systems differ from one to another. The ac capacity can be as small as 1 ton or as big as 100 tons.

A look at the efficiency of the rooftop unit in the HVAC system

The availability of the RTUs is in several efficiencies. There is also increasing effort to enhance the efficiency of the system, and create a kind of retrofit options. These are the options that will be able to improve the efficiency of the units installed. The efficiency of the RTUs can be lowered through low maintenance practices. It can also be affected by an inability to handle the system operation.

The RTUs performance metrics are what you need to know to understand its overall efficiencies.

The Seasonal Energy Efficiency Ratio

The Seasonable Energy Efficiency Ratio ( SEER) is the adjustable rating according to load in the residential representative. The seasonal energy efficiency ratio applies to the rooftop units with 5.42 tons or lesser cooling capacity.

Energy Efficiency Ratio

The energy efficiency ratio (EER) measured in Btu per hr is the cooling rate divided by the power at a full-load condition measured in watts. Many things are included in the power measurement, and they include controls, fan motors, and compressors.

The Integrated Energy Efficiency Ratio

The integrated energy efficiency ratio ( IEER) defines the total operating efficiency at the one hundred percent, seventy-five percent, fifty percent, and twenty-five percent operating loads. The energy efficiency ratio will determine the rooftop unit that will work more efficiently.

Conclusion

With the various operating efficiencies associated with the rooftop units, it is easy to conclude that the 

RTUs is the most efficient type of Heating, Ventilation, and Air Conditioning System. It is the system that requires low input to get a massive result in forms of thermal comfort in a building and more. That can explain the reason for the increasing number of organizations and public facilities with the RTUs system installed.

Who Can Make Do With A Single-Stage HVAC Setup?

Single stage HVAC systems are very common. Having a single stage heating or cooling system means that your air conditioner or furnace has only one level of cold or hot input. Single stage HVAC systems generally have a furnace or boiler and an air conditioning system. Multi stage HVAC system is a little bit different from single stage systems. These systems have several outputs for heating and cooling.

Things to know about the HVAC setup

A single stage HVAC setup might be right for you although there are factors involved such as location, size of house and budget. Single stages HVAC systems either run at full capacity or it doesn’t run at all. There also several reasons as to why you might prefer a single stage system. Some of this reason includes the following:

  • Easy to install and maintain
  • Cost effective
  • Less complicated

HVAC Installation tips you should know

Installing a single stage HVAC system isn’t so difficult and its price can vary depending on the ac unit you are purchasing. Compared to multi stage systems, single stage systems typically cost more due to their complexity. Because a single stage HVAC system is either ON or OFF, operating it is a piece of cake. If you don’t need it, simply turn it off and if you need it, just turn it off. Handling a single stage HVAC setup doesn’t require a lot of experience and pretty much anyone can handle it.

The advantages of the single stage HVAC system

As single stage HVAC systems have its advantages, it also has its disadvantages. One of these disadvantages is the fact that single stage HVAC systems don’t really give you a lot of control. Since all you have to do is turn it ON and OFF, it’s almost impossible for you to get the desired conditions and settings. Also because of the lack of control, it’s definitely suitable for all places with high levels of humidity.

The need for the single stage HVAC system

Having to install a single stage system is cost effective; however paying back the electric bills can be an entirely different story. Due to its lack of customization, single stage systems are not capable of saving energy compared to multi stage systems. As a result, you get to pay higher electric bills.

Conclusion

A single stage HVAC setup has its own problems. This doesn’t mean that it is unsuitable for all areas. As we mentioned earlier, enjoying a single stage system depends on the size of the house, location, budget and other factors.
