COIL:COOLING:DX:CURVEFIT:OPERATINGMODE
DX cooling coil performance for a single operating mode which may have one or more speeds.
Name
Type: alphanumeric
Rated Gross Total Cooling Capacity
Type: real number
Total (sensible+latent) cooling capacity not accounting for the effect of supply air fan heat. Rating point: air entering the evaporator coil at 26.7 C dry-bulb/19.4 C wet-bulb, and air entering the condenser coil at 35 C dry-bulb/23.9 C wet-bulb. gross capacity excluding supply air fan heat
Unit: W
Default: autosize
Rated Evaporator Air Flow Rate
Type: real number
Flow rate corresponding to rated total cooling capacity, Rated SHR and Rated COP. Should be between 0.00004027 m3/s and 0.00006041 m3/s per watt of rated total cooling capacity.
Unit: m3/s
Rated Condenser Air Flow Rate
Type: real number
Used to calculate evaporative condenser water use.
Unit: m3/s
Maximum Cycling Rate
Type: real number
The maximum on-off cycling Rate for the compressor, which occurs at 50% run time fraction. Suggested value is 3; zero value means latent degradation model is disabled.
Unit: cycles/hr
Minimum: 0.0
Maximum: 5.0
Default: 0.0
Ratio of Initial Moisture Evaporation Rate and Steady State Latent Capacity
Type: real number
Ratio of the initial moisture evaporation rate from the cooling coil (when the compressor first turns off) and the coil's steady state latent capacity at rated air flow rate and temperature conditions. Suggested value is 1.5; zero value means latent degradation model is disabled.
Unit: dimensionless
Minimum: 0.0
Maximum: 5.0
Default: 0.0
Latent Capacity Time Constant
Type: real number
Time constant for the cooling coil's latent capacity to reach steady state after startup. Suggested value is 45; zero value means latent degradation model is disabled.
Unit: s
Minimum: 0.0
Maximum: 500.0
Default: 0.0
Nominal Time for Condensate Removal to Begin
Type: real number
The nominal time for condensate to begin leaving the coil's condensate drain line at the coil's rated air flow rate and temperature conditions. Nominal time is equal to the ratio of the energy of the coil's maximum condensate holding capacity (J) to the coil's steady state latent capacity (W). Suggested value is 1000; zero value means latent degradation model is disabled.
Unit: s
Minimum: 0.0
Maximum: 3000.0
Default: 0.0
Apply Latent Degradation to Speeds Greater than 1
Type: choice
(Yes or No)
Default: No
Condenser Type
Type: choice
(AirCooled or EvaporativelyCooled)
Default: AirCooled
Nominal Evaporative Condenser Pump Power
Type: real number
Rated power consumed by the evaporative condenser's water pump
Unit: W
Minimum: 0.0
Default: 0.0
Nominal Speed Number
Type: integer
Must be lower than or equal to the highest speed number. If blank, defaults to the highest speed number used.
