At the 3rd China International Green Innovation Technology Products Exhibition held in Guangzhou recently, Grundfos Pumps launched five new energy-efficient new pumps with the theme “Facing the Energy Crisis”. “The common feature of these pumps is that they will learn. They can control the speed of the pump by learning the personal habits of the individual or the entire city, so as to save energy. The secret of all this is built into the pump. The smart chip," said Mr. Liu Hongcong, senior vice president of Grundfos.

According to reports, when the sun is sunny, regular heating plus the thermal efficiency of the sun may cause the building to be warmer than average. At night, when there is no sunlight, the temperature of the building will be slightly lower. The system will accurately capture the temperature changes of the building and adjust the supply of hot and cold water for the building based on the outdoor temperature to ensure constant temperature in the building.

The intelligent control algorithm in the chip can accurately collect temperature data to complete the adjustment of the water supply. This is the process of “learning” the pump; the temperature effect is very large. The advantage of this is that not only can the building be kept at a constant temperature, but also the heat source can be maintained. The heating area will be expanded with the same efficiency. The Grundfos Thermalsmat Systematized Products unveiled at the Greentech show solved the building heating problem. After installing the system in each building, the building's heating system automatically “learns” how the building’s temperature changes.

The system can also be compatible with a variety of data communication protocols, real-time communication control with a variety of existing building management and control systems, and online real-time adjustment via Grundfos-developed remote control system. "Even with your mobile phone, you can adjust the temperature in a building far away in Denmark." Liu Hong-Cong said.

This magical heating system also has a “Home Edition”: MAGNA3 is a circulation pump designed by Grundfos specifically for home heating systems. It can maximize the building’s learning by learning residents’ water usage and heating needs. Heating efficiency. People can easily control the speed of hot water circulation in their home by using a terminal device such as a mobile phone to control their home temperature. This data is then captured by a heat meter built into the pump to collect data for temperature control throughout the building.

In addition, Grundfos also provides energy auditing services for retrofitting of old pumping stations in order to reconstruct the current state of high energy consumption of the old pumping stations. After conducting on-the-spot investigations and data collection on the practical use rules, noise requirements, etc. of old pumping stations, reasonable guidance on pump assembly and installation is given. This ensures maximum energy savings after installation.

It is reported that if this type of energy auditing service can be used in all central heating districts in China and the "smart" pump is installed, it is estimated that at least 1.4 billion kWh can be saved annually, which is equivalent to less than 800,000 tons of carbon dioxide emission per year. , less burning 460,000 tons of bituminous coal. If the world can switch to such an energy-efficient pump system, the total power consumption will be reduced by 4%, which is equivalent to 1 billion people's annual household electricity consumption.
