Public Health Centers
Public health centres are increasing in number and expanding across the semi-urban areas in India. Providing HVAC cooling to each of these spaces is not feasible as costs involved are huge. Basic comfort cooling to the occupants and doctors in these kinds of spaces is needed, considering the fact that most parts of India are either humid or dry.
Oorja offers Slab Cooling integrated with the two-stage cooling tower to these spaces. Structure Cooling is done during the construction of the building where PERT pipes are embedded in the ceiling of the building.
By using slab cooling with the two-stage cooling tower:
1. Comfort cooling can be achieved through a normal ceiling fan operation.
2. The power consumption of cooling tower is only 0.05 kW/tonne while the conventional chiller consumes around 1-1.2 kW/tonne.
3. Life of the system is more than 50 years as PERT pipes are used.
4. The maintenance of slab cooling systems is simple and cost-effective as minimal resources are used.
5. Temperatures from 20-30 degree Celsius can be maintained depending on the wet-bulb temperature (WBT) of the space.
Figure 1 Structural Cooling
Structure Cooling is done during the construction of the building where PERT pipes are embedded in the ceiling of the building. Structure cooling takes away the heat present in the structure of the building reducing the re-radiated heat. Structure cooling can provide 40-45 W/sq.mt of area installed.
Structure cooling with the two-stage cooling tower is the way to go forward for low energy consumption comfort cooling, specially in places where conventional HVAC systems can’t be implemented such as Govt offices and primary health centres. By using structure cooling, we offset a significant amount of GHG emissions by consuming only 0.05 kW/tonne of cooling.
