One Way Outdoor
This route is used for one way interpolation of manufacturer's capacities at outdoor design conditions.
Example:
My summer outdoor design is 92° dry-bulb and my indoor design is 63° wet-bulb
Route:
POST https://hvacmath.com/api/v1/interpolate
JSON Input Example:
aboveDesignThe manufacturer's capacity above the outdoor design conditions.
belowDesignThe manufacturer's capacity below the outdoor design conditions.
designInfoThe design information for the project.
houseLoadThe house load for the project at design conditions.
manufacturerAdjustmentsOptional adjustments multipliers to the manufacturer's capacity.
systemTypeThe system type for the interpolation.
