HPWHsim - Version 1.13.0

• Add's a Scalable HPWH with resistance elements and fixs preset HPWH capacity and volume.
  • Functions to scale capacity and COP or specifically set capacity for scalable HPWH models
• Tracks HPWH condenser water temperature.
• Function to get the minimum operating temperature of a compressor.
• Sets a cap on the max outlet temperature of a compressor based on the refrigerant.
  • Can only set setpoint higher than this if the HPWH has resistance elements.
• Force an external heat source to heat to its shut off condition to enter the proper end of heating logic.
• Optional additional standby condition for heating.
• Function to get sizing fractions corresponding to when the compressor turns on (aquastat fraction) and when the compressor turns off (percentUseable)

Bug Fixes:

• Inversions were not mixed in SP HPWH's when setpoint temperature was decreased. In case of cold weather packages the setpoint would be decreased when air temperature drops too low (i.e. < 40F)
• getSetpoint() unit conversion.
