On November 14, 2024, according to the information of the State Intellectual Property Office of China, Zhuhai Gree Electric Appliances Co., Ltd. applied for a patent entitled "Refrigeration system, its control method and cold storage", public number CN 118935868A, the application date is August 2024.

The patent abstract shows that the invention discloses a refrigeration system, a control method thereof and a cold storage. The refrigeration system comprises a refrigerant cycle composed of an intermediate heat exchanger, a heat exchange coil arranged in a water tray under the condenser and a circulating pump. When the suction overheating is too low, the refrigerant temperature in the suction tube is increased through the refrigerant cycle; The liquid reservoir outlet of the refrigeration system is divided into two branches, the first branch is communicated with the evaporator inlet, the second branch is communicated with the evaporator outlet pipe, the second branch leads part of the refrigerant to be throttled and mixed with the evaporator outlet refrigerant to reduce the suction superheat.

The world famous refrigeration equipment manufacturers officially settled in the cold storage cold chain industry, indicating that the industry's heat continues to rise.
