We all go to supermarkets to buy groceries and other items. You must have always wondered why there are no normal fans used inside them, but large ducts with cool air coming out of them.
It is indeed an engineering marvel that this concept of HVAC is able to maintain a desired cool temperature, and humidity and also keep exhaust air out of human touch.
All this is possible through proper HVAC design in supermarkets. Because, with such a large number of people present and also to maintain a cool temperature for food items, normal fans and ACs would not be possible to implement this.
The HVAC concept in supermarkets is difficult to understand but is totally reliable and efficient. In this post, we will learn the concept of ventilation (HVAC) used in supermarkets.
As you know, HVAC stands for heating, ventilation, and air conditioning. First of all, let us understand why such complex engineering HVAC design is required in supermarkets.
When a person comes to buy items in closed indoor supermarkets, he comes more to focus on his items and get a luxurious feeling. But, if he is sweating, not getting cool air, or smelling dumb air around him, then it will reduce his overall shopping experience; as naturally he will start to feel suffocated.
Air Quality Index (AQI) plays a very important role inside supermarkets. Be it food courts, cafes, washrooms, shops, game zones, or multiplexes, the proper surrounding air is a must in presence of such a large amount of people and items. Temperature and humidity must be maintained and less number of pollutants must be present in the air.
With more number of people, humidity starts to increase which causes sweating. When you open or close the main doors in entry and exit, some level of outside air gets accumulated and after a prolonged period of time, it will start to suffocate people inside. So, HVAC design is required to be proper in supermarkets.
Let us have a look at some design standards followed in supermarkets for proper ventilation.
In this way, we understand the concept of HVAC in supermarkets.
