- C++
Published by pmskintner about 5 years ago

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.
