Refrigeration and air-conditioning diagrams
In refrigeration and air conditioning technology standardised symbols are used
for process schematics. For refrigeration, the standard EN 1861 Refrigeration Systems
and Heat Pumps applies, and for air conditioning technology, the standard DIN 1946 Ventilation
and Air Conditioning Technology applies. These Visio shapes provide the most frequently used symbols. More
symbols will be provided in due course. Early users of these stencils will get free updates.
