In the hot summer days, people are looking for cool places everywhere, and major shopping malls around the world have adopted various methods to cool down the heatstroke. On July 6, the reporter saw at the Dongtai Shopping Plaza in Linyi District that the cooling measures of the mall were different. It installed two water source heat pump units to provide heating, cooling and domestic water supply. Dongtai Shopping Plaza is the largest comprehensive shopping mall in Linyi District, covering an area of ​​30,000 square meters. According to Li Jinshan, manager of the property department of Dongtai Shopping Plaza, after applying the water source heat pump technology, the square can save more than 700 tons of coal per year, save about 100,000 yuan, and save more than 800,000 yuan a year.
Energy-saving, high-efficiency and environmental protection are the most important features of groundwater source heat pump technology. Its working principle is to extract energy from groundwater, and then the water pump is used as a brine to raise the temperature and then sent to the building to save the boiler room system. There is no combustion process, heating power is one-fourth of the electricity consumption of electric boilers, and cooling power is only half of the power consumption of split air conditioners. It is very suitable for large energy-consuming households such as enterprises and residential quarters.
Up to now, in addition to Dongtai Shopping Plaza, a large number of new renovation projects such as Olympic Garden and Founder Shangcheng have also adopted groundwater source heat pump technology. The area of ​​the district using water source heat pump technology has reached more than 400,000 square meters. It saves more than 9,300 tons of coal and coal, saves about 1.35 million kWh, saves more than 10.66 million yuan of capital, and reduces carbon dioxide emissions by more than 5,000 tons.
