The 36th International Refrigeration, Air Conditioning, Heating, Ventilation and Food Freezing Processing Exhibition (referred to as "2025 China Refrigeration Exhibition") will be held from April 27th to 29th at the Shanghai New International Expo Center. The theme of this exhibition is "Intelligent Connection of Cold and Warm, Shared Future", with nearly 1200 industry brands from 32 countries and regions on display. The total exhibition area is 115000 square meters, and it is expected to attract more than 80000 visitors to visit on-site.

At this exhibition, Sifang Optoelectronics will provide environmental comfort applications, A2L/A3 refrigerant safety applications, cooling fans, controllers/detectors and other solutions in the fields of refrigeration, air conditioning, heating, ventilation, etc., and will showcase multiple new products at booth W5B49.

01 Environmental Comfort Application

In the field of indoor air quality monitoring, Sifang Optoelectronics has launched new products such as small-sized high-precision carbon dioxide sensors, laser dust sensors PM2020L, and multi in one integrated air quality sensors AM2020 to meet the diversified needs of end customers for air quality monitoring. On this basis, Sifang Optoelectronics further expands its business scope and invests in the field of air quality improvement. It introduces negative ion generators and fragrance generators, which have been widely used in automobiles, into household appliances such as air conditioners and refrigerators to achieve efficient air purification and create a comfortable and healthy home environment for users.

Safe Application of 02A2L/A3 Refrigerant

Based on a comprehensive sensor technology platform and technological innovation, Sifang Optoelectronics has launched a series of refrigerant leakage monitoring sensors, covering three technical routes: infrared, thermal conductivity, and ultrasound, suitable for monitoring various A2L/A3 refrigerants (such as R454B, R454C, R1234YF, R1234ZE, R290, etc.). In response to the safety issues caused by refrigerant leakage in cold storage, we have independently developed refrigerant (R717) and refrigerant (R744) leakage monitoring sensors, which can accurately monitor ammonia and carbon dioxide gas leaks. They have the advantages of strong anti-interference, high detection accuracy, fast response, and long service life, effectively preventing accidents such as explosions and ensuring the safe operation of cold storage refrigeration systems.

03 Controller/Tester

To meet the market's demand for efficient, energy-saving, and intelligent temperature control solutions, Sifang Optoelectronics has launched color screen and segmented code screen intelligent temperature controllers, which can automatically control the opening and closing of fan coil units, electric valves, electric ball valves, air valves, and heating equipment at the end of the air conditioning system, achieving comfortable and energy-saving operation. And with years of technical experience, independent innovation capabilities, and a sound production quality system in the field of gas sensors, Sifang Optoelectronics provides a one-stop solution for OEM/ODM of controllers/detectors, covering the entire process of appearance design, software and hardware development, structural design, and manufacturing services.

04 Application of cooling fan

For home appliances such as range hoods, floor scrubbers, and refrigerators, Sifang Optoelectronics has launched a variety of axial fans and blowers with different specifications to accurately match the cooling needs of various devices, efficiently remove internal heat from the equipment, and ensure long-term stable operation of the equipment. Fans have advantages such as excellent heat dissipation performance, durability, low noise, and can also be customized to meet customers' differentiated application needs.

Sifang Optoelectronics sincerely invites you to visit the exhibition site (W5B49) from April 27-29. We will showcase the latest industry solutions to you and look forward to exploring cooperation opportunities with you to jointly promote industry development.
