Training Programme -
Post Graduate Diploma in Air Conditioning System Design (HVAC), Air Conditioning System Design (HVAC)

Eligibility :

Fresh/ Experienced - Diploma /Degree in Mechanical / Production Engineers.

The design of the HVAC component is critical to achieve an efficient and effective environmental control system. The successful integration of building constraints, air movement conditions and equipment selection can positively impact system overall performance and decrease utility expenses and capital expenditures. To achieve the optimal design, one should needs good analytical skills and up-to-date technical knowledge of various system designs.
