Common refrigerants used in cold storage include ammonia (R-717), which is highly efficient and cost-effective for large systems, and hydrofluorocarbons (HFCs) like R-134a and R-404A, which are used in smaller applications. Carbon dioxide (R-744) is also gaining popularity due to its low environmental impact and efficiency in certain conditions. The choice of refrigerant often depends on factors such as system size, application, environmental regulations, and energy efficiency requirements.

Cold storage facilities are used to keep food frozen. They are often used by hunters after a successful hunting season and need more room to store their meat.
Refrigerant R-502 is a medium-pressure refrigerant primarily used in commercial refrigeration systems, particularly in low-temperature applications such as freezers and cold storage facilities. It was commonly utilized in older refrigeration and air conditioning systems, especially in transport refrigeration and industrial processes. However, due to its ozone depletion potential, R-502 has been phased out in many regions in favor of more environmentally friendly alternatives.
Is there a special requirement to have a recovery tank at 400psi for all refrigerant
cold storage of grains
This is most definitely not a DIY task. To do it properly, you need to first test the purity of the refrigerant, which takes special equipment to do, as does actual recovery and storage of the refrigerant.
Disposable refrigerant containers are only used for virgin refrigerant.
These terms also apply to public warehouses. Dry storage is also known as Ambient storage. This is space where the internal temperature fluctuates based on the outside temperature. Cold storage is where the temperature is held at a certain range specific to the product being stored. Modern electric refrigerant systems are used, in addition to ammonia to brine systems (older technology), which are still used today.
