Hvac heat load programs

It can also be essential in estimating medium to large projects. There are an array of heating and air conditioning computer design programs that you can get directly online or through a download. I've heard some businesses say they have not adopted design software in their business practice because they hear it is too complicated to use.

Unless you are an engineer looking for a specific program to integrate with your current engineering software which you can find here , there are many other programs that have different learning curves. Some are so basic to use, by just adding in amounts or dimensions, where others will need a little time and attention to detail. Software designers design their products to be user friendly.

Most have detailed manuals and are customer support based. This heat loss or heat gain is caused by the fact that the transfer of heat, even in a super insulated house, cannot be completely stopped. If we know how much heat is being transferred through its walls, ceilings, floors, windows and doors, ducts and through infiltration air leakage on an hourly basis, then we could calculate the precise size heater or air conditioner the house would need to maintain a comfortable temperature.

This calculation is called a load calculation. The obvious reason is to prevent installing a system that is too small to do the job. The real reason for a load calculation is to size the equipment in order to assure comfort, economy, and good indoor air quality. When heating, it is important to size the system as close to the heat loss calculation as possible to prevent 1 drafts, 2 hot and cold spots, and 3 short cycling of equipment. When a furnace is grossly oversized, the unit will constantly shut off and on.

It may satisfy the thermostat but leave other parts of the home either over or under heated thus, leaving the occupants uncomfortable. A correctly sized unit runs longer, resulting in a better distribution of air and reduced short cycling.

Short cycling also leads to higher energy costs. Each time a furnace fires up, it must heat up the heat exchanger before the indoor fan comes on. This heat is wasted up the chimney. Short cycling short on-off periods increases the amount of heat wasted up the chimney. A great overall experience! Roquey from Integrity Comfort Solutions says, "I have used Wrightsoft since the days of monochromatic screens and the spreadsheet-only format.

I've attended several classes, been to the World Headquarters in Lexington, and even hosted training classes. The level of support is phenomenal. Both in the classroom, call in and email. I've used the Right J, Right Draw modules extensively in the new construction markets not only for the purpose intended, but also to "value engineer" the materials selection process for my clients.

I can't imagine a better product. The learning curve is pronounced and requires commitment on the part of the user, but with constant use it becomes almost second nature. Within the past year, we have actually picked up new accounts because our customers were so impressed by the professionalism of our designs, particularly when we go up against contractors who are giving them what amounts to a crayon rendition on a napkin.

For a standard 3, square foot, 4 bedroom house, doing the load calculations manually would take many hours. Then I found Wrightsoft, and by using their Right-J and Right-D, I was able to produce load calculations and duct design in about an hour.

Al Gagne from Bayside Mechanical says, On our Training: "I've been to three of your trainings over the last 7 years and every time I go I learn something new. I can simply import the AutoCAD building plans as a layer in the program, trace to complete the load calculations and add my ducts to the design, saving me a considerable amount of time.

That was a long time ago and changes in HVAC technology have greatly improved since then. Energy efficiency is now a concern. Homes are better insulated and engineering improvements to doors and windows have changed exceedingly. For example, an older home that had single pane window glass, and little or no insulation in the walls or attic, would be sized for a 3 ton AC system.

With upgrades to the windows and more insulation in the walls and attic, a new 2.
