has hot gas bypass Whether or not hot gas bypass is provided for the compressor. TRUE = Yes, FALSE = No. Ideal capacity of compressor001 SIERRA02-0434C3 1800.0 ideal capacity Compressor capacity under ideal conditions. Usually measured in Watts (W, J/s). has value A relationship defining the value of a certain property, e.g., energy or power isSpaceOf Relation between a building space and the building or building space it belongs to.

For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called "watt". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of the Smart Appliances ontology, but this list can be extended. Building A building represents a structure that provides shelter for its occupants or contents and stands in one place. The building is also used to provide a basic element within the spatial structure hierarchy for the components of a building project (together with site, storey, and space).

Usually measured in Watts (W, J/s). Computer Science Building 1 power source Type of power driving the compressor. impeller diameter Diameter of compressor impeller - used to scale performance of geometrically similar compressors. Usually measured in millimeters (mm). location The relation between something and the point, or other geometrical thing in space, where it is. For example, the realtionship between a radio tower and a Point with a given lat and long. Or a relationship between a park and its outline as a closed arc of points, or a road and its location as a arc (a sequence of points). Clearly in practice there will be limit to the accuracy of any such statement, but one would expect an accuracy appropriate for the size of the object and uses such as mapping . Impeller diameter of compressor001 SIERRA02-0434C3 5.9 Building space An entity used to define the physical spaces of the building. A building space contains devices or building objects. https://w3id.org/ifc/IFC4_ADD1#IfcCompressor Compressor A compressor is a device that compresses a fluid typically used in a refrigeration circuit. is contained in A relation between an object and the physical space in which it is located. cycles per second Example of use for the SAREF extension for building devices 1.0 Compressor speed of compressor001 SIERRA02-0434C3 3.0 Power of compressor 001 SIERRA02-0434C3 902.0 Spatial thing Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes. compressor speed Compressor speed. Usually measured in cycles/s. is measured in A relation between a measurement and the unit of measure in which the measurement value is expressed. Nominal capacity of compressor001 SIERRA02-0434C3 680.0 Measurement Represents the measured value made over a property. It is also linked to the unit of measure in which the value is expressed and the timestamp of the measurement. 1 refrigerant class Refrigerant class used by the compressor. CFC: Chlorofluorocarbons. HCFC: Hydrochlorofluorocarbons. HFC: Hydrofluorocarbons.
