СО2 refrigeration equipment from PRIMEHOLOD

The unique characteristics of carbon dioxide provide significant ecological and economical advantages. Carbon dioxide is a natural coolant, safe for environment, it has low global warming potential and high volumetric refrigerating effect. It is widely popular, inexpensive and non-inflammable.

High volumetric refrigerating effect (5-7 times higher than ammonia) provides smaller compressor cubic capacity and smaller pipe diameters.

It features high coefficient of performance (COP) in condensation temperature lower than the critical temperature of CO2.

Cycles with CO2 can operate in supercritical and subcritical areas. Therefore, there are two cycle types available for CO2: transcritical and subcritical.

The characteristics of transcritical cycle:

- It operates both in supercritical and subcritical areas

- The pressure may vary from 30 to 100 and more bars

The characteristics of subcritical cycle:

- The pressure range: 10-30 bar

- The conditions are similar to traditional refrigerating systems

- Common components can be used

Carbon dioxide (CO2) belongs to natural substances, and it doesn’t destroy the ozone layer, as opposite to Freon gas whose usage is limited by Kyoto Protocol. The leading European manufacturers have developed compressors ad components of refrigerating systems working on CO2. Refrigeration units on CO2 provide high efficiency degree, higher than Freon- and ammonia-based systems provide in low temperature range. CO2-based systems utilize subcritical or transcritical cycles, and therefore - cascade or single-staged scheme. The problems of using CO2 in refrigerating units include higher requirements to materials and quality of assembling due to high operating pressures in the system and risk of incidental pressure - up to 70 atm. However, CO2-based refrigerating systems are compact in size and provide significantly lower materials consumption.

PRIMEHOLOD offers the best refrigerating units that correspond to modern tendencies in refrigerating technologies development. Phone no.: (044) 369-58-19, (044) 227-50-17.
