Heating Coil
Heating Coil (Electric Heating)
Sizing Method
Specify the Sizing Method by choosing between Autosize or Manual. If Manual is chosen, the user must provide all sizing parameters.
Coil Efficiency
Specify the Coil Efficiency as a user-inputted efficiency in decimal units (not percent), accounting for any loss. For electric coils, this is typically 100%.
Capacity
Specify the Capacity to set the maximum capacity of the coil in watts (W). This controlled coil will only utilize the necessary capacity to meet the control criteria, whether it's temperature or capacity controlled.
Heating Coil (Water Heating)
Sizing Method
Specify the Sizing Method by choosing between Autosize or Manual. If Manual is selected, the user must provide all sizing parameters.
Max. Water Flow Rate
Specify the Max. Water Flow Rate to set the maximum water flow rate (m3/sec) through the coil. This field is utilized when Coil Performance Input Method is set to U Factor Times Area And Design Water Flow Rate. This field is autosizable.
Capacity
Specify the Capacity to set the maximum capacity of the coil in watts (W). This controlled coil will only utilize the needed capacity to meet the control criteria, whether it's temperature or capacity controlled. This field is autosizable.
Inlet Air Temp
Specify the Inlet Air Temp as the inlet air temperature (in degrees Celsius) corresponding to the rated heating capacity. The default is 16.6.
Inlet Water Temp
Specify the Inlet Water Temp as the inlet water temperature (in degrees Celsius) corresponding to the rated heating capacity. The default is 82.2.
Output Air Temp.
Specify the Output Air Temp as the outlet air temperature (in degrees Celsius) corresponding to the nominal heating capacity. The default is 32.2.
Output Water Temp.
Specify the Output Water Temp as the outlet water temperature (in degrees Celsius) corresponding to the rated heating capacity. The default is 71.1.
Ratio for Air and Water Convection
Specify the Ratio for Air and Water Convection as the ratio of convective heat transfers between the air side and water side of the heating coil at rated operating conditions. The default is 0.5.
