Today, ground source heat pump central air conditioning system was officially put into use in Shanghai KSB Pump Co., Ltd., which is also the first industrial enterprise in China to use ground source heat pump system. The project can make good use of underground shallow geothermal resources for heating and cooling, the image of the point of view, this is to the land for energy for daily production, energy saving and environmental protection. According to reports, the underground shallow temperature perennial maintained at 18 to 20 degrees, ground source heat pump central air conditioning system is to extract this place, in winter heating, cooling in the summer, but also zero emissions. Although this system is 30% more expensive than a normal central air conditioner, the cost can be recovered quickly. Thermometer display, an area of ​​2,600 square meters of workshop, the overall temperature close to 25 degrees, higher than the outdoor more than ten degrees. On the surface, the secret is that these 30 outlets on the wall of the workshop, in fact, the real heat comes from the depths of 100 meters underground. The main use is free underground energy provided to our heating or cooling and it is not discharged (waste water) is very environmentally friendly. Using this system can be recovered in less than two years with the money invested. If you invest more than one million yuan using this system, we can save 500,000 yuan for each year. It is reported that the ground source heat pump central air conditioning system in the United States, Europe has been more popular, but mainly used in homes, which is the first time in our country in industrial systems.
