When you invest in a new HVAC system for your home or for your business, you may come across the term “load calculation”. You might be wondering what it means, right?
Well, the heating and cooling load calculation is the first step of the iterative HVAC design procedure. It is something that ensures comfortable heating, cooling, and ventilation for the residents. Some people simply replace the old HVAC system with the new one without considering the impact of HVAC load calculation for better performance. And that’s not the reality!
Having accurate heat load calculation won’t just help you get the perfect size of the HVAC system, but will also ensure a comfortable in-house experience for the residents. Contractors may have different ways of measuring size and load calculations. Some just look at the premises and tell you the necessary size whereas others may take some burden to count windows or other areas to estimate HVAC loads more precisely.
The only problem with conventional heat load calculation is that it is a time-consuming process. And that is where HVAC load calculation software comes in handy. In this blog post, we will discuss what HVAC load calculations are, why it is important to perform a heat load calculation, and important tips to get accurate HVAC load calculations.
Understanding HVAC load calculations…
The cool or heat load calculation is how HVAC professionals or home auditors determine the correct size of your home’s HVAC system. Whether you’re building a new home or installing a new HVAC system, the HVAC load calculator helps you get the most accurate HVAC system for your home.
HVAC software can help you identify the best size, application, and type of HVAC system suitable for your home. Instead of conventional methods, you can use Heating Load Calculation Software to do the calculations quickly. The home auditor typically considers the following parameters or factors:
- Total square footage of your home
- The number of windows, doors, and entryways
- Check for insulation material used, the density, and how it is installed
- Make sure you consider all the floors including the number of living space vs attic space
- Don’t forget to check sunlight blockages, if any
- Check for the window treatments used to keep the sun out
- Always check duct size, condition, and vent system installed
Considering all these factors, the contractor may use HVAC load calculation software and figure out the exact size of the HVAC system to be installed at your home.
Reasons why you need an HVAC load calculator to measure loads
Ensures you get an accurate HVAC system installed at your home. The size of the HVAC system plays a vital role. If you have a small HVAC system installed, it will run continuously to keep your home warm or cool. This results in uncomfortable room temperature and higher energy bills. Similarly, the larger HVAC system will waste energy due to frequent on and off. To get rid of the inappropriate size HVAC system, you can use HVAC load calculation software. With the right measurements, you can rest assured to get an accurate HVAC system designed for your unique needs.
Helps you become energy efficient. Since you have an accurate and correctly-sized HVAC system installed at your home, it will consume less energy and produce better results. Unlike other HVAC systems, which are not designed appropriately, they will not require more energy to cool or warm your home. This will greatly reduce the energy bills.
No additional cost. In case of incorrect heat load calculations, the service provider may either install too large equipment. You will be required to pay more for the high-capacity system, which is not at all required for your home. Using heating load calculation software, you can easily bring down the overall equipment costs.
Better health and safety. Inappropriate size of the HVAC system may result in unstable temperature or humidity control problems. This has adverse side effects on the health of your family members. Professional HVAC software will ensure the proper size of your HVAC system and will contribute towards your healthy life.
Improve HVAC system’s life. Since your HVAC system runs smoothly without any additional load, it will greatly reduce the wear and tear of the system and boost the overall lifespan of the equipment.
Understanding the side effects of inappropriate HVAC load calculations
When you don’t have accurate HVAC load calculations, you end up installing an inappropriate HVAC system. You will not just pay unnecessary additional costs for a larger unit, but you will also face health issues and poor performance and life of the HVAC system.
Tips to get precise HVAC load calculations
- Always upgrade yourself with the latest technology and tools. Conventional methods of heat load calculations are erroneous and time-consuming. Get help from professional HVAC software or home energy audit tools to get accurate results.
- In case of doubt, always ask the home auditor.
- Make sure you never ignore short cycles of HVAC equipment.
- To achieve optimum temperature and humidity, always consider thermal enclosure and internal loads.
How much does it cost to carry out load calculation?
Well, the HVAC load calculator is not that expensive. You can easily find suitable HVAC load calculation software online, such as EDS. You can do almost everything you ever imagined using such professional heating load calculation software on your own.
In the end, what matters the most is accurate heating or cooling load calculations to get the right HVAC system installed for your home. You can definitely follow a few handy tips mentioned in this blog to achieve the most accurate calculations for your home. A well-designed and rightly sized HVAC system will bring noticeable benefits such as improved energy, reduced energy bills, and comfortable temperature for your home.
