Before the air conditioning project is put into operation, the overall safety and operation performances of the unit are tested to verify the compliance with the design and acceptance requirements. The operation environment of the unit is more complex than that in the laboratory. Although its laboratory data meet the relevant requirements, its performance differs from that in the laboratory after operation. Therefore, field testing and acceptance are required before the HVAC goes into operation. 

● Safety testing of electrical circuits and electrical systems
