About HVAC Load Plus
The HVAC Load+ iPhone app allows you to perform detailed heating and cooling block loads for small commercial and residential buildings out in the field by taking advantage of the simplicity and power of the iPhone.
It performs heating and cooling block load calculations based upon industry standard calculation methods. The following is just a small sample of the features included in this app:
1. Includes a 1000+ world-wide city weather database
2. Includes data for 100s of construction types for walls, roofs, floors, doors, windows, skylights, ceilings, and more
3. Allows you to create and store an unlimited number of projects. You can also copy existing projects to new projects for easy reuse of data
4. Allows you to specify an unlimited # of opaque types (ie – doors, walls, roofs, floors, ceilings), window types, and skylight types for each building
5. Allows you to view comprehensive cooling and heating load breakdown reports including breakdown by opaque load, window load, skylight load, infiltration load, ventilation load and internal load contributions
6. Opaque inputs include opaque type, opaque construction number, dimensions, and opening areas
7. Window inputs include window type, internal and external shading type, overhang dimensions, window area, and more..
8. Skylight inputs include skylight type, dimensions, orientation, and more..
9. Additional input types include # of people, # of bedrooms, ventilation airflow, and more..
10. Includes the ability to display a comprehensive HTML report that you can email to yourself or others, and it also includes a spreadsheet attachment that you can open in Excel to further massage data on your desktop
11. Includes ability to input your company information to display on the emailed report
12. Includes ability to display units in either English (IP) or Metric (SI).
13. Equipment location services
It also includes 2 bonus modules:
1. The "HVAC Equipment Locator" has the same functionality as our stand-alone Locator app. It allows you to input information about all of your HVAC equipment, upload it to a remote web server (at www.carmelsoft.com/EL), and SAFELY share information about it with other technicians within your company. The equipment's GPS coordinates become its globally unique identifier, allowing you to input and retrieve information about it just by standing next to it.
2. The “HVAC Quick Load” module allows you to quickly perform rule-of-thumb heating and cooling load calcs based upon just inputting the building type, square area, and # of people. Please see the description located under the stand-alone "HVAC Quick Load" app for more details about it.
The benefits of using this app are:
1. Great for use out in the field. Quickly size heating and cooling equipment, show the client, then email the results back to your office for further analysis.
2. Show off your advanced on-screen reports to clients convincing them you are using cutting-edge technology
3. Save time by inputtin
