This is an interesting innovation from Linric Company. Using this calculator you can quickly compare the calculated ventilation loads based on all ASHRAE Climatic Design points for a given location.
You can even compare these to your own set of outside design conditions. The innovative display shows at a glance the highest load design point and how the other design points compare.
This screen operates in single and multi-location modes. Click here to see the Multi-Location Mode screen

Top Section - Location Selector and Screen Configuration
Country, State/Providence and CitCountry, State/Province and City drop-down boxes are used to select a location.
To save a location so it will appear first click the "Save Location" button. To
the right enter the air flow rate and the temperature the air is to be cooled
to.
Middle Section - Inputs for your Middle Section - Inputs for your own comparison. (optional) Using
user inputs calculates and displays the cooling load values. Graphical display
shows comparitive load sizes to all other loads currently shown.
Lower Section - Loads calculated using the ASHRAE Climatic Design values
This section displays the resulting cooling load based on each of the ASHRAE
Climatic Design values. Total, sensible and latent loads are shown both
graphically and numerically. Sensible Heat Ratio is calculated and shown at the
right. The graphic for the design value that results in the highest load always
occupies the full width of the graphic area.
