Ammonia/CO2 secondary refrigerant refrigeration system for meat or fish​

Company Instruction:

Sunicorn headquarter is located in Shenzhen city, production and R&D team is located in Shenzhen city and Kunming city in Yunnan province.Our main products include all kinds of vacuum cooler, cold storage room,ice maker etc.Company in the production of vacuum pro-cooling equipment, large cold storage, refrigeration equipment has been successfully applied in 12 provinces of China and other professional engaged in the preservation of circulation and food processing industry, a well-known enterprises, and has exported to Malaysia, Singapore, Thailand, the United States, Mexico, Eastern Europe and other places.And in the United States, California, Florida and other places set up a firm and after-sales service center. At any time to provide users with convenient and efficient technical advice, maintenance and domestic and foreign parts supply.

System Description:

An ammonia/CO2 secondary refrigerant refrigeration system mainly includes refrigeration compressor unit, ammonia condense,ammonia liquid receiver,condensing evaporator,CO2 liquid receiver, refrigeration shield pump, terminal evaporator,etc. The high temperature side is a conventional ammonia refrigeration system.

Scope of Application:

  • Applicable to the case where there are strict requirements for ammonia charging volume.
  • Applicable to medium and large or medium and small refrigeration systems.
  • Scope of application of the NH3/CO2 secondary refrigerant system:

The evaporation temperature range of CO2 is -52℃~0℃,which can meet the load needs of low temperature cold storages,high temperature cold storages,low temperature anterooms, ice making rooms,IQF machines, etc. The NH3/CO2 cascade refrigeration system is more suitable in the range -52℃~-25℃ in view of the efficiency factor;

  • Applicable terminal evaporator forms:all forms such as air coolers, coils, IQF machines,etc.;
  • Applicable to the case with drastic load fluctuation;
  • Applicable to the case with large feeding height or large feeding resistance of the refrigerating circuit.

System Advantages:

  • The efficiency of the CO2 secondary refrigerant system is close to that of conventional ammonia refrigeration systems;the ammonia refrigerant charge volume of the CO2 secondary refrigerants system is only about 10% of the ammonia pump system.
  • Ammonia refrigerants is concentrated in the machine room and doesn’t enter the personnel operation room, so the safety is improved.
  • Because of using the pump feeding mode, the CO2 secondary refrigerant refrigeration system also has the advantages of the ammonia pump feeding system and thus good stability.
  • CO2 is a phase change secondary refrigerant. The circulation volume of CO2 is far too smaller than that of other secondary refrigerants on the premise of transmitting the same refrigerating capacity.
  • Used as a secondary refrigerant, CO2 doesn’t contact refrigeration oil;the terminal evaporator can keep high efficiency heat exchange in the state of no oil.
  • Compared with other secondary refrigerants,CO2 has low viscosity,high heat exchange COP,large specific heat and small flow rate.Water defrosting or CO2 hot gas defrosting can be used in evaporator defrosting.
  • Compared with conventional refrigeration systems, the CO2 secondary refrigerant system has low cost of operation and maintenance.

Cold Storage Room Instruction:

The modular cold room series is an integrated family of sandwich panels designed for quick cold room assembly. The panel configuration has been reduced to a minimum, so the overall effect is to offer the clients maximum design possibilities for cold rooms with a minimum amount of panels required on the site. All products from the modular range can be easily assembled without the need for special tools. Likewise they can be dismantled easily in order to move or enlarge them. The modular range has a wide variety of applications from general food storage to mortuary chambers.

Material of the Cold Room:

A. Panel: polyurethane insulation foamed by high pressure, density above 43kg/m3.

B. Economical panel thickness: 50mm,75mm, 100mm, 150mm for choice.

C. STeel sheet: Painted galvanized steel.

D. Door: Convex door, hinge door and sliding door available.

E. Compressor: Copeland, Bitzer.
