R404A is the mainstream refrigerant for modern cold storage piston refrigeration compressor. It maintains volumetric efficiency above 76% under -20℃ evaporation temperature and fits both medium preservation and low-temperature freezing cold storage. Many existing export cold storage projects adopt this refrigerant.
R22 refrigerant faces phase-down regulations in most global regions. The production and refill supply keep shrinking year by year. Using R22 piston compressor for new cold storage projects will bring difficulty in purchasing refrigerant and spare parts after 5 to 8 years.
Low-GWP refrigerants gradually enter cold storage industry to meet carbon reduction requirements. These refrigerants require piston compressor with upgraded internal sealing and lubrication system. Ordinary R404A piston compressor cannot be directly refilled with low-GWP refrigerant without component modification.
Flammability classification is a key factor for refrigerant selection. A2L low-GWP refrigerants have mild flammability, so cold storage equipment room must adopt ventilation and leakage detection devices. This increases initial engineering investment compared with non-flammable refrigerants like R404A.
Refrigerant charging amount must follow the nameplate specification of cold storage piston compressor. Overcharging raises condensing pressure and power consumption, while insufficient charge reduces cooling capacity and causes overheating of compressor motor.
xtldcool piston refrigeration compressor factory produces models compatible with R404A, R22 and low-GWP refrigerants. Buyers need to confirm local refrigerant regulations of target country before selecting compressor refrigerant configuration.
For cross-border cold storage contractors, refrigerant policy varies greatly in different countries. Some regions restrict refrigerant import quantity and impose carbon taxes on high-GWP refrigerants. Ignoring local regulations may lead to project operation obstacles after equipment delivery.
