The outdoor temperature when the compressor is automatically turned back on following an automatic shut off because of low outdoor dry-bulb temperature. This field is only used for the calculation of HSPF. If this field is not provided, then outdoor bin temperature used in the HSPF calculation is always considered to be greater than this temperature and 'Minimum Outdoor Dry-Bulb Temperature for Compressor Operation' field described above. This assumption is based on AHRI standard 210/240 (2008) and can introduce significant error in the final value of HSPF. | |

Coil:Heating:Desuperheater¶
from idfpy.models import CoilHeatingDesuperheater
Desuperheater air heating coil. The heating energy provided by this coil is reclaimed from the superheated refrigerant gas leaving a compressor and does not impact the performance of the compressor. If the coil is located directly in an air loop branch or outdoor air equipment list, then it is controlled on leaving air temperature and the Temperature Setpoint Node Name must be specified. If the coil is contained within another component such as a unitary system, then the coil is controlled by the parent component and the setpoint node name is not entered.
