Yesterday, it was learned from MICOE that the 2023 MICOE Air Energy Heat Pump Development Summit released White Paper 1.0 on the Use of Air Energy in Antarctica. Mr. Li, President of MICOE, introduced that the company had customized MICOE ultra-low temperature variable frequency unit for the glass greenhouse at the Great Wall Station in Antarctica, China by relying on advanced facilities such as the -40 ℃ air energy ultra-low temperature laboratory to meet its vegetable growth needs and maintain the glass greenhouse in a normal temperature range of 15 ℃ -26 ℃, allowing the scientific research team here to enjoy "vegetable freedom".

With the improvement of China's technological and manufacturing levels, the Antarctic scientific research team has established a glass greenhouse at the Great Wall Station, using soilless cultivation methods to achieve "vegetable freedom". However, the implementation of this plan will face various difficulties and challenges. The climate here is complex, and to ensure the necessary room temperature environment for vegetable growth, stable and efficient heating technology must be adopted.

To tackle this problem, MICOE and the China Polar Research Center are collaborating to make a tentative use of the latest air energy heat pump products to heat the vegetable greenhouse at the Great Wall Station. “The air in Antarctica is thin; the ultraviolet radiation is strong and extremely corrosive. Currently, no Antarctic exploration station of any country uses air energy products for heating.” Mr. Zhang, the R&D leader of MICOE, introduced that during the plan discussion period, they modeled and analyzed the heat pump application scenarios for the Great Wall Station meteorological conditions and the requirements of the research team, and they conducted research in the -40 ℃ ultra-low temperature laboratory of the enterprise. Heating capacity verification and reliability testing were conducted on the selected heat pump host. After repeated discussions, the R&D personnel of MICOE have finally decided to use the strong heat system technology DDHOT "double heat ring" to provide warmth to the Great Wall Station in Antarctica, China and ensure the supply of vegetables in daily lives of the expedition team members.

In response to the extremely low temperature of outdoor environment, MICOE adopts a new jet enthalpy increasing technology and a unique enthalpy increasing branch design. At the same time, in conjunction with the 3-minute intelligent defrosting core technology independently developed by the enterprise, it integrates fast defrosting, precise defrosting and high-efficient defrosting, achieving quasi dual compression with a single compressor. In addition, the body shell adopts low-temperature resistance, corrosion resistance and structural reinforcement design, which can resist high humidity and salinity, and the invasion of high wind speed. Even in extremely cold weather of -36 ℃, it still operates stably and is as warm as spring.

Mr. Zhang introduced that in order to protect the ecology of the "last pure land of humanity" from damage, the MICOE’s ultra-low temperature variable frequency unit achieved a comprehensive heating energy efficiency of 3.26 under an environmental temperature of -12 ℃, exceeding the national level 1 heating energy efficiency requirement of 3.2. Currently, it has the highest energy-saving performance among similar products, with COP (h) (i.e. heating performance coefficient) ≥ 2.65. At the same time, the device also adopts full DC frequency conversion technology to adjust the operating power in real-time, while ensuring the temperature of the glass greenhouse, trying to reduce energy consumption and emissions, and minimizing the impact on the Antarctic environment and ecosystem.

In addition, the product also has good maintainability and can be easily maintained and repaired in extreme environments, providing important support and assistance for scientific research and technological innovation.
