As the summer season approaches, all major shopping malls in Beijing are implementing the air conditioning temperature control standard for public buildings, setting the air conditioner at 26 degrees Celsius to reduce power consumption and achieve energy saving. Ms. Chen found that while there were other energy-saving ways and spaces in the air-conditioning temperature limit, she suggested to the Beijing Municipal Government’s proposed collection office that large-scale shopping malls could replace unnecessary lighting and replace them with energy-saving lamps. The way of consuming incandescent lamps further saves electricity.
Shopping mall lighting energy consumption
In front of a 10 square meter jewellery counter on the ground floor of Wangfujing Oriental Xintiandi, the enamel jewelry is dazzling in the light from all directions. From the ceiling lights on the ceiling to the various decorative lights in the counter, there are nearly 60 large and small. The counter glass was slightly hottened by the lighting in the cabinet. The salesperson Niu Mian reluctantly told the reporter: "The lights are turned on every morning when they start business. It is really hot to stand at the counter and bake a day." On the counter of the same sales jewelry, the counter lamp of the "baked man" was not seen. Several delicate small glasses reflected the soft light, and the jewelry was also set to be crystal clear and quite charming. In an ONLY store of less than 40 square meters, there are more than 60 "small barrels" of lights, which are densely arranged on the ceiling. The clothes are illuminated by the lights, and there is still a hanging in the middle of the room. A dazzling crystal decorative light.
Brand counters are common in major shopping malls in Beijing. In order to be dazzling, the clerk explained the lighting as "this is part of the store design, showing the brand's taste, it is very important." But in fact, when incandescent lamps work, only 7% to 8% of the electrical energy is converted into visible light, and more than 90% of the electrical energy is converted into heat, which is why customers and clerk have a "baked pan" feeling.
Energy-saving lamps are of great benefit to shopping malls
Can reducing the heat dissipation of the lamp to affect the air conditioning refrigeration? The reporter interviewed a professional on this issue. Dajin (China) Investment Co., Ltd. General Manager of the Beijing Sales Department Fujita Hibachi told reporters that the use of incandescent lamps and energy-saving lamps has different effects on the power consumption of air conditioners. Especially in places where electricity is concentrated in shopping malls, the air conditioning temperature is also set at 26 degrees Celsius, but since the heat emitted by incandescent lamps is much larger than that of energy-saving lamps, more heat is offset by the cold air generated by the air conditioner, and the air conditioner is 26 degrees Celsius. The return air temperature requires a higher speed operation and consumes more power. The use of energy-saving lamps, in addition to the power saving of the lamps themselves, can also help the air conditioner to save electricity.
Mr. Fujita said that incandescent lamps are banned in some countries in Europe. However, due to the soft lighting effect of incandescent lamps, from the perspective of professional design, the decorative effect is indeed better than the energy-saving lamps, so some places now choose more incandescent lamps.
