BANDON won Air Source Heat Pump Central Heating Best Application Award

The 2020 China Heat Pump Industry Annual Conference and the 9th International Air Source Heat Pump Industry Development Forum were grandly held at the Crowne Plaza Hefei from July 15 to 16! Fang Qing, Vice Chairman of the China Energy Conservation Association, first delivered a speech at the annual meeting and pointed out: "In 2020, although the "COVID-19" has brought huge challenges to the development of the industry, the continuous favorable policies and the continuous increase in market demand still give us firm confidence. Major opportunities for the development of the industry are just around the corner. For example, the clean heating pilot cities are gradually entering the final stage of the tough battle; in the non-central heating areas of cold and hot summer and cold winter areas, air source heat pumps are gradually gaining more users' favor; in the air energy building supporting market, new progress is being made in provinces such as Zhejiang, Jiangsu, Shandong, Fujian, and Anhui; in terms of industrial and agricultural drying, the market is constantly expanding, and policy dividends are emerging in an endless stream. In this special year where opportunities and challenges coexist, how should the Chinese heat pump industry "turn crisis into opportunity and move forward steadily"? This requires the advice and active efforts of every colleague in the industry, and requires all sectors of the industry to work together and move forward together."

The conference also held the selection and commendation of the "Energy Saving Cup" Fifth Air Source Heat Pump Design Competition. BANDON was successfully selected for the "Best Application Award for Air Source Heat Pump Central Heating" with its "High-Power Commercial Inverter Central Heating for Yutian County Middle School in Hebei Province" project!

The reason why this project stood out from many participating cases is that it is a very representative case. The project covers a total area of 8,000 square meters and uses 6 pcs of BANDON 38P commercial inverter equipment. Commercial high-power inverter heating can be said to be a new trend in commercial heating in the future. Why do you say that? Let's learn about the trend of commercial inverter heating from the following aspects!

First: Design and Selection Perspective

Everyone knows that when designing and selecting air source heat pump products, climate issues need to be considered. Since the lower the temperature in winter, the lower the heating effect of the heat pump product, the local minimum temperature needs to be considered as a reference parameter when designing the ratio. Generally, there are not many days with the lowest temperature, so many projects are often too large during the design and selection process, and the operating load of the equipment is not high most of the time! The emergence of commercial high-power inverter products can solve this problem well when designing centralized heating projects. Combined with the frequency modulation power of the equipment and the heating load required by the minimum temperature, it is OK to make an appropriate ratio!

Second: Energy Saving of the System

In the design of the water system, many ON/OFF heating projects are equipped with heat storage tanks to reduce the frequent start-up of the machine, but the heat storage tank in the system is actually an energy loss point, because no matter how good the insulation is, it will dissipate heat. Commercial high-power inverter equipment does not need a hot water storage tank in system design, because the machine itself will automatically adjust the frequency according to the system to meet the heat required for heating. This not only reduces the heat loss of the hot water storage tank, but also the stable operation of commercial inverter equipment is more energy-efficient than ON/OFF equipment, so the system's energy saving is better than ON/OFF products!

Third: Equipment frosting

During the operation of the air source heat pump, frosting is also a problem that needs to be solved. If frosting and defrosting are not solved well, the energy consumption of the equipment will be very high. Commercial high-power inverter equipment, due to its relatively stable operation and small compressor pressure difference ratio, is often in low-pressure operation, and the number of frosting times is significantly lower than that of ON/OFF products!

As the requirements for clean heating in the north become higher and higher, there will be more and more centralized heating projects, and commercial high-power equipment will also be a new application trend! BANDON has been focusing on the research and development and manufacturing of commercial high-power inverter heating since 2016. It can be said that it is one of the earliest companies in China to enter the field of commercial inverter technology. The company's R&D director has 20 years of technical R&D experience in the field of inverter. At present, the control programs of the system are independently developed. In recent years, it has stood out in the market with commercial high-power inverter heating, and has continuously won the northern clean heating BOT project. In 2019 alone, it has completed nearly 1 million square meters! In the first half of 2020, it was not affected by the epidemic at all, and the orders received were close to the whole year of 2019. This also shows that the market demand for commercial inverter heating equipment is gradually expanding! It can be said that BANDON's ability to stand out and win the "Energy Saving Cup" Air Source Heat Pump Central Heating Best Application Award is well deserved!
