7.9 CompressorType ObjectType Definition
The CompressorType is the representation of a compressor and extends its supertype by specific Nodes. According to EN 1012-1/ISO/DIS 18623-1, a compressor compresses a gas or vapor media to a pressure higher than that at the inlet. It is illustrated in Figure 23 and formally defined in Table 27.
