    These units share the same water system to supply the building with cooled or heated water. Hybrid tandem, associating one inverter and one fixed-speed compressor, can better match the capacity requirement compared to a modular chiller with fixed-speed tandem compressors and increases efficiency.

  8. Schematic capture - Wikipedia

    en.wikipedia.org/wiki/Schematic_capture

    Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit, is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. [1]
