HVAC Load Calculation Apps

To determine the right size of the a/c unit or furnace for a property, you need to calculate the cooling or heating needs of the premise that is to be supplied. This is done by calculating load. Gone are the days when engineers would make educated guesses on the heating gains and losses of a home or office and have units manufactured on this basis. That’s definitely a good thing because back then, companies would often install units that were too big to be on the safe side. These would lead to cold and hot spots on the property.

Today, software systems and apps ensure 100 percent accurate calculations of heating and cooling needs. Apps like HVAC Load Plus and Duct Calc Elite, both available from the App Store, are proving pivotal in the process of sizing heating and cooling units.

With HVAC Load Plus, you can show data to clients in the field and send it to the office for further analysis. The capability to input data in the field saves time. The app has a vast database featuring weather information for thousands of cities, additional input variations for properties such as ventilation airflow and number of people and bedrooms, equipment location services, data for hundreds of construction types for doors, floors, ceilings, roofs, and windows, and the option to download a full data report in HTML.

Duct Calc Elite helps engineers work more efficiently by calculating ductwork sizing accurately. As an expert, you know that duct sizes that are too big compromise velocity and sometimes you don’t feel the heating or cooling effects. On the other hand, if they’re too small, the whole HVAC system needs to work more to keep the premises sufficiently cooled or heated.  Duct Calc Elite calculates the parameters you need to know to establish the exact duct size, including the square footage of the premises, cubic feet per minute, square footage of each individual room, and friction loss rate. It features pressure drop, duct size by airflow, and duct size by dimension. The dimensional units available are centimeters, millimeters, or inches. All airflow units, pressure loss units, velocity units, and duct material types are all covered. Elevation is measured in imperial or metric units.

3D Printing

The versatility and speed of 3D printing have rendered it capable of producing HVAC units and specialized unit parts and prototypes. Thanks to this, they are not only being created much faster than before, but their quality is also much better. 3D printed units and parts are more durable and efficient than conventionally manufactured ones because they are made with a seamless layering process. As a result, they are resistance-free.  

Experts believe that in the future, 3D technology will reinvent the way companies build whole HVAC units. For example, 3D printing could be the answer to a client’s inquiry into the possibility of having a highly customized unit installed in a hard-to-reach location. The unit could be printed with less waste and in half the time a traditional manufacturing method would need. The ability to ensure faster turnaround would be of great benefit to businesses. The printing process is also environmentally-friendlier than traditional methods.

“Proposal” Apps

Customers today expect to receive goods and services at the speed of light, and those your HVAC business caters to are no exception. Few people have the time to wait for a provider to come to their home and spend hours there in order to get a new a/c system or furnace. The vast majority wants to get pricing by phone or online.

Moreover, a quote can feel like an ultimatum. Put in a “take it or leave it” situation, a potential customer will start looking for other offers to compare pricing. 

Proposal apps are a new software application where a price book is used to create proposals on the spot. Customers like to have a choice, and package proposals give them the context they need to decide immediately while shifting focus to the value and features as opposed to the price. Proposal apps can help a company offer pricing in tiers, such as “good,'' “better,” and “best” price.

Air Purification Systems

Moving beyond mere efficiency, technological advances in the HVAC industry are improving health and safety. As users begin to demand maximum air safety, air purification methods are getting more effective and smarter. More specifically, users are focused on getting rid of common allergens and VOCs (volatile organic compounds), which are known to reduce air quality.

One of the best ways to improve air purity is by enabling online monitoring of air quality and air filters. NASA has been the source of some of the most effective technologies in this area. For example, a system notifies you if the air quality has deteriorated or a filter needs to be replaced.  To ensure top air quality, air purification systems combine streamlined air cleaning methods with energy efficiency.

Internet of Things (Iot)

The Internet of Things (IoT) has changed how machines work and interact. An HVAC system with a Wi-Fi-connection does not need to rely on system malfunction or user recognition to avoid potential errors. Preventative diagnostics are in place to help detect potential malfunctioning. With the help of IoT-enabled devices, your HVAC system could notify the repair team or owner and they can take measures to minimize further damage, like powering down or resetting the system.

Internet-enabled HVAC devices are also better able to detect changes in the environment, in particular if the devices are equipped with digital thermostats. Then, they make automatic adjustments to maintain a comfortable temperature on the premises.

Digital Thermostats

On this note, smart or digital thermostats have many benefits over conventional ones, including ease of use and accessibility. Most smart thermostats are controlled from a tablet or smartphone. This technology saves users money by allowing them to manage the temperature in their homes or offices remotely. HVAC systems and units have become more customizable, energy efficient, and compatible with smart home devices, thanks to digital thermostats.

The HVAC Industry is Entering a New Era

Technology has helped usher in a new era for the HVAC industry, which is responding to user demands for smarter, more energy efficient models more adequately than ever. Businesses in this industry are also seeing positive developments in customer service. These essential technologies are creating a more energy efficient and cost effective industry.
