When calculating the electricity load of small shops? The following aspects are worth considering:
1. 1 store use function
Because shops are commercial and residential facilities? Facing the street? So it is all-encompassing in terms of use function? You can use beauty salons, dry cleaning, restaurants and so on. Heavy electricity load? There are also stationery, house rental, toy stores and so on. Less electricity load? The design should be considered according to the overload standard.
1.2 usable area of shops
Because the store tries to "make the best use of everything" in use? And will not cancel some electrical equipment that must be equipped with a fixed load because of the small area? So the load index per unit area should be appropriately increased? Meet various business needs.
1.3 store height and direction
The height of a small shop is generally around 4m? The height of the ceiling is about 3 meters. And some skirt shops are 6m high? When calculating the load, it should be considered that the merchant may change the pavement to two layers. Double the business area? The corresponding power load has also doubled? For shops facing east or west in direct sunlight? Because of the heavy air conditioning load? Therefore, it is necessary to make a big estimate in the load calculation.
1.4 storage of electrical equipment
Because quite a few small shops are for fire safety reasons? Liquefied gas and gas are not allowed to be used, so the use of electric water heaters and rice cookers is very common, which leads to the rising power load. This load should be fully considered in the design stage, which is common in beauty salons and barbershops. At the same time, it must also be taken into account that quite a few shops have three-phase electrical equipment, such as dry cleaners, bakeries and photo processing shops. If the developer can't limit the nature of the use of merchants, three-phase power supply should be considered.
I hope the above reference will help you.
