Pharmaceutical Cold Storage Compressor | Temperature Stability Control and Refrigerant Selection Specification for Vaccine Cold Storage,
Paragraph 1: The pharmaceutical cold storage compressor needs to ensure a temperature control accuracy of ± 0.5 ℃, with priority given to low fluctuation single-stage piston models, suitable for constant temperature storage in vaccine cold storage at 2 ℃~8 ℃.
The pharmaceutical cold storage includes vaccine cold storage and raw material medicine cold storage. The national standard requires temperature fluctuations not to exceed ± 0.5 ℃. The compressor must be equipped with energy regulation to avoid frequent start-up and shutdown, which may cause temperature fluctuations in the storage. The semi closed piston models of Xitelidou are widely used on this track. Redundancy should be reserved for the calculation of cold load in vaccine cold storage, with a cold load of 100-140W per cubic meter of pharmaceutical cold storage. Continuous ventilation and open door sampling within the storage for 24 hours will continuously bring in humid and hot loads. R404A and R507 are preferred as refrigerants in pharmaceutical scenarios, while R32 belongs to A2L combustible refrigerants. Most owners of pharmaceutical indoor sealed cold storage projects do not accept R32 compressors to avoid the risk of leakage and fire. The compressor and air cooler of the pharmaceutical cold storage must be matched with a dual circuit redundancy scheme. If a single unit fails, the backup unit can be started within 10 minutes to ensure that the storage temperature does not exceed the standard. The operating current of the compressor needs to be connected to the cold storage monitoring system. When the current deviates from the rated value by ± 12%, a remote alarm will be triggered to facilitate the engineering department of the pharmaceutical enterprise to arrange maintenance as soon as possible. The export order of pharmaceutical cold storage requires strict documentation, including CE certification, refrigerant safety report, temperature stability test report, and all documents need to be accompanied by English versions to be provided to overseas purchasers. When the refrigeration unit factory is equipped with a pharmaceutical unit, the heat transfer margin of the condenser is increased by 25% to prevent the condensation pressure from rising during high temperature weather in summer, and the cooling capacity of the compressor from decreasing, resulting in uncontrolled storage temperature. The maintenance cycle of the pharmaceutical cold storage compressor has been shortened, with frozen oil testing completed every 2000 hours and valve plates and bearings checked every 6000 hours to avoid unexpected shutdowns that may cause drug scrap losses. The number of pharmaceutical cold storage projects in Africa and Southeast Asia has been increasing year by year, and the local power supply voltage fluctuates greatly. A matching voltage regulator is standard, and voltage fluctuations exceeding ± 10% can damage the compressor motor winding. Medical cold storage cannot use ultra-low temperature two-stage compressors for conventional 2-8 ℃ insulation. The control logic of the two-stage unit is complex, and temperature drift is more likely to occur under low load, resulting in higher operation and maintenance costs.
