LOW REFRIGERANT PRICE – LOWER RUNNING COST
While natural refrigerants significantly reduce direct emmisions, they cal also be very energy efficient, thereby simultaneously reducing in-direct emissions. R290 (propane) plug-in refrigeration units have been reported to deliver up to 30% higher energy efficiency than their HFC counterparts. About 5-10% of this can be accredited to better thermodynamic and trasport properties of hydrocarbons. The rest is most likely due to component modifications such as improved compressor or heat exhanger design, as well as variable speed drives.
Co2 is a natural refrigerant, compliant with international regulations that are steadily limits on the use of synthetic refrigerants.It is a low cost refrigerant, available anywhereCo2 equipments and componets indicated transcritical Co2 systems as the most energy-efficient solution for medium-sized to large supermarkets.Currently installed transcritical Co2 centralised systems were indicated to offer 7-30% energy savings.
