energy both between equipment internal to the facility and between internal equipment and the external environment, if adequate measures are not taken to disrupt the coupling path. The particular grounding and bonding requirements and constraints imposed on non-electric utilities are summarized in table 2-3
Other changes include the following:
Heating, ventilating and air conditioning (HVAC). HVAC is the network of equipment that regulates the internal physical environment of the facility. This system consists of the furnaces, airconditioners, heat pumps, and humidifiers that condition the air, ducts, vents, and fans that distribute the conditioned air throughout the facility.
Context Considerations
The HVAC ducts are routed throughout the facility and are likely to make frequent contact with structural elements. The duct system may or may not be electrically continuous.
Application industry
The products can be used in the following industries: power plant, paper making, steel, mining, rubber, water supply, cement, chemical industry, glass, printing
Textile, machinery, plastics, coatings, medicine, hospitals, food, hotels, scientific research institutions
