HVAC Cooling Details

Use this component to set the parameters of a HVAC cooling system that has been assigned with the "Honeybee_HVAC Systems" component.
Not all of the inputs on this component are assignable features of all HVAC systems. However, most HVAC systems have these features and, if you assign a parameter that is not usable by a certain HVAC system, the "Honeybee_OpenStudio Systems" component will give you a warning to let you know.


_coolingAvailSched__coolingAvailSched_A text string representing the availability shcedule of the cooling system. This can be either a shcedule from the schedule libirary or a CSV file path to a CSV schedule you created with the "Honeybee_Create CSV Schedule" component. The default is set to 'ALWAYS ON.'Goo
_coolingCOP__coolingCOP_A number (typically greater than 1) that sets the reference coefficient of performance (COP) of the primary cooling component (under design-day conditions). The COP is the ratio of heat removed by the cooling system per unit of electricity input. For a large HVAC system, this input refers to the COP of the chiller compressor. For a smaller system, this likely refers to the COP of the direct expansion cooling coil or equivalent. Defaults range from 2 to 5.5 depending on the system type.Goo
supplyTemperature_supplyTemperature_A number representing the temperature of the water leaving the chiller in degrees Celsius. This input does not have an effect on direct expansion cooling systems. If left blank, the default temperature is usually 6.67 degrees Celsius.Goo
pumpMotorEfficiency_pumpMotorEfficiency_A number between 0 and 1 that represents the motor efficiency of the chilled water pump. This input does not have an effect on direct expansion cooling systems. If left blank, the defualt efficiency is usally 0.9.Goo
centralPlant_centralPlant_Set to "True" to have all instances of this HVAC Type have a single central cooling plant. If set to False or left blank, each branch of a HBZone data tree that is plugged into this component will have a separate cooling plant.Goo
heatRejectionType_heatRejectionType_An integer that represents the type of heat rejection used by the cooling system. This input does not have an effect on direct expansion cooling systems. If left blank, the defualt is usally 0 = water cooled. Choose from the following options: 0 = Water Cooled - The chiller (or VRF heat pumps) will be cooled using a condenser water loop with cooling tower and will use a higher default COP. 1 = Air Cooled - The chiller (or VRF heat pumps) will reject heat directly to the air and will have a lower default COP.Goo
