HVAC stands for Heating, Ventilation, and Air-Conditioning-three closely related fundamental functions with both commercial and residential applications. The concept was coined by Volkart Brothers, being the pioneers in this segment, and was introduced way back in 1950.
The steady growth of the real estate market in India has created opportunities for major developers to promote large format office spaces and associated structures like malls, resorts, hi-tech hospitals, etc. This growth has necessitated in realizing the importance of the HVAC and Fire-fighting systems in both residential and commercial structures as a prime essential for safety and health.
The primary use of HVAC is to regulate room temperature, humidity, and air flow, ensuring that such elements remain within their acceptable ranges. Effective control of such factors minimizes health-related risks.
For application of MS Pipes in this segment, details regarding the common practices followed, sizes of steel pipes used, and specifications required are as given below.
Class of MS Pipes to be used in Air Conditioning and Chiller Systems depends on environmental conditions like proximity to sea, corrosiveness, cooling flow, cooling zone and operating pressure.
