March 22 News: According to information from the National Intellectual Property Administration, Jinfang Energy Group Co., Ltd. has applied for a patent titled “Double Cold Source Heat Pump Refrigerant Self-Balancing Device and System.” The application publication number is CN121702052A, the application number is CN202610201102.2, the publication date is March 20, 2026, and the application date is February 11, 2026. The inventors are Han Shuang, Wang Hongji, Cai Rui, Wei Cheng, Zhang Chao, Zhou Zhiwei, and Zhang Xiaoping. The patent agency is Nanjing Quanmeng Intellectual Property Agency (General Partnership), with patent agent Shen Shuai. The classification codes are F25B13/00, F25B41/24, F25B41/42, F25B45/00.

Patent Abstract: The invention discloses a double cold source heat pump refrigerant self-balancing device and system, related to the technical field of heat pump systems. The device includes a heat pump component comprising a compressor, a four-way reversing valve connected to the compressor, a first heat exchanger, a second heat exchanger, and a third heat exchanger connected via the four-way valve, and a throttling valve on the third heat exchanger. It also includes a balancing component with first, second, and third shut-off valves arranged beside the first, second, and third heat exchangers, a refrigerant tank, and fourth and fifth shut-off valves on the refrigerant tank. The invention ensures that when environmental temperatures change, the system automatically stores or releases refrigerant to balance pressure, preventing significant pressure fluctuations caused by switching heat exchanger modes, thereby maintaining stable and efficient operation of the heat pump system with obvious application value.
