Product Description
Applications of CO2 Refrigeration System
Main Feature
Safety
NH3 in the high temperature part only, extremely small charging volume of NH3;
CO2 is safe, nontoxic and noninflammable, thus ensuring the safety of people and food.
Environmental protection
Both NH3 and CO2 are nature refrigerant.
NH3: ODP=0, GWP=0;
CO2 : ODP=0, GWP=1;
Energy saving
NH3 is the refrigerant with the highest efficiency;
CO2 has good heat transfer fluid characteristics and excellent
performance at low temperature.
System Type
NH3/CO2 cascade refrigeration system applicable to -52 ~30 evaporation temperature rang.
CO2 screw refrigeration compressor unit
Features of the CO2 screw refrigeration compressor unit
- Adoption of the fourth generation internationally most advanced bilateral asymmetric full-arc envelope profile which is characterized by numerical control grinding with high precision.
- The compressor with new-type cast iron materials resistant to low temperature realizes reliable performances under low temperature working conditions.
- Adoption of the high precision bearings of Japan NSK Company leads to long service life.
- Adoption of British JohnCrane shaft seals and the independent oil feeding cooling system make the sealing system more reliable.
- The precision of components is high resulting in low running noise, little vibration and long service life of the compressor.
- The efficiency of the oil separator is high and its oil separation efficiency reaches 99.999%.
- High efficiency oil cooler has high heat exchange efficiency and small volume.
- Combination of forced oil feeding with differential oil feeding is for lubrication; the oil way is controlled by a constant pressure valve to make oil pressure stable and reliable.
- Simple and clean unit pipeline, small pipeline loss, simple and convenient operation.
- An independent suction filter structure is adopted, thus facilitating thermal insulation in the low temperature area, having no influence on the castings in the high temperature area of the unit body and ensuring the compressor normal work.
- Direct connection with laminated joint slack, good automatic centering capability, long service life.
NH3/CO2 secondary refrigeration system applicable to -30~0 evaporation temperature range.
CO2 secondary refrigerant modular unit
Technical characteristics
The CO2 secondary refrigerant modular unit consists of NH3 semi-hermetic compound two-stage refrigeration compressor, oil separator, oil cooler,
economizer, liquid receiver (concurrently as siphon tank), condensation evaporator, gas-liquid separator, CO2 shield pump, unit frame, protective door,
electrical control, etc.
Features of the CO2 secondary refrigerant modular unit:
- The protection level of the whole unit is high and its installation position is flexible without need to set up a special machine room.
- The matching evaporative condenser can run in dry form at <-5ºC ambient temperature.
- The unit uses the variable frequency control mode to realize automatic power frequency conversion without disturbance.
