Example of use for the SAREF extension for building devices
Compressor speed. Usually measured in cycles/s.
compressor speed
Compressor capacity under ideal conditions. Usually measured in Watts (W, J/s).
ideal capacity
Diameter of compressor impeller - used to scale performance of geometrically similar compressors. Usually measured in millimeters (mm).
impeller diameter
A relation between an object and the physical space in which it is located.
is contained in
Relation between a building space and the building or building space it belongs to.
isSpaceOf
Nominal capacity. Usually measured in Watts (W, J/s).
nominal capacity
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 .
location
A relation between a measurement and the unit of measure in which the measurement value is expressed.
is measured in
Whether or not hot gas bypass is provided for the compressor. TRUE = Yes, FALSE = No.
has hot gas bypass
Type of power driving the compressor.
power source
Refrigerant class used by the compressor. CFC: Chlorofluorocarbons. HCFC: Hydrochlorofluorocarbons. HFC: Hydrofluorocarbons.
refrigerant class
A relationship defining the value of a certain property, e.g., energy or power
has value
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).
Building
An entity used to define the physical spaces of the building. A building space contains devices or building objects.
Building space
A compressor is a device that compresses a fluid typically used in a refrigeration circuit.
Compressor
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.
Measurement
Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes.
Spatial thing
The unit of measure is a standard for measurement of a quantity, such as a Property. 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.
