What are the safety protection norms for refrigeration system in cold storage?

There are many factors affecting the cost of cold storage construction, such as the size of the cold storage, the selection of the refrigeration system of the cold storage, the insulation materials of the cold storage, etc.

Among them, for the selection of the refrigeration system of the cold storage, in addition to considering the price, professional cold storage engineers will give professional suggestions on aspects such as the environment where the cold storage is built, the size of the cold storage, and refrigerated items. After weighing the pros and cons, enterprises make the best choice for cold storage construction. No matter what choice is made, the safety protection specifications of the cold storage refrigeration system must be strictly followed. Otherwise, once a refrigeration system with ammonia refrigerant leaks or other accidents occur, it will not only pollute the stored objects but also endanger the equipment and personal safety.
First, pressure safety protection in the safety protection specifications of the cold storage refrigeration system. In order to prevent the refrigeration system from operating under overpressure, safety valves, pressure relays or differential pressure relays and automatic alarm lights and other pressure protection safety equipment are installed on the refrigeration equipment. In case of overpressure operation, the safety equipment will act automatically to discharge part of the gas in the system to the atmosphere or shut down automatically to ensure the safety of equipment and personnel.
Second, liquid level safety protection in the safety protection specifications of the cold storage refrigeration system. To prevent safety problems caused by excessive liquid level in equipment such as gas-liquid separators and intermediate coolers or operational failures caused by too low liquid level, float ball liquid level controllers or commonly used liquid level automatic control devices for refrigeration equipment are usually used to automatically control the liquid level of these devices.
Third, temperature safety protection in the safety protection specifications of the cold storage refrigeration system.

The exhaust temperature of the compressor of refrigeration equipment, the temperature of lubricating oil, the inlet and outlet temperatures of cooling water, and the temperature of the motor are all important parameters for checking the safe operation of the refrigeration system.

Thermometers must be installed near the heat source on the refrigeration equipment for daily management and monitoring.
Other safety protection specifications for the cold storage refrigeration system, such as setting up an emergency ammonia discharge valve in the ammonia refrigeration system, installing a check valve on a screw compressor to prevent the refrigerant from flowing back, and setting up an emergency shutdown device in the refrigeration system.
