Conventional Cooling system
The conventional HVAC system has a chiller and its purpose is to chill water. This water is then circulated to every floor of the building through heavy duty pumps. Every floor has a tapping wherein water is taken inside AHU. AHU has a motor and a blower, which enables air flow. As a result, there is heat exchange between air and water inside AHU and air becomes cold. This cold air is then pushed to the respective offices that provides cooling.
In large offices, it is very difficult to have air balancing. This means comparatively hot places having lesser supply of cold air and cold at places receiving more air supply.
Also, if no human occupancy is there and hence doesn’t require cooling, but AC being centralized, it cannot be turned off, which is a sheer waste of energy. Our efficient and smart HVAC condemns these major problems, hereby making it really SMART.
