Överföring av slingor vid 31C skulle avsevärt sänka kyleffekten än en CO2 / R744 - ADVANSOR - Natural Refrigerants Company.

Downloadable! Heat pump (HP) is one of the most energy efficient tools for address heating and possibly cooling needs in buildings. Growing environmental concerns over conventional HP refrigerants, chlorofluorocarbons (CFCs), and hydrofluorocarbons (HFCs) have forced legislators and researchers to look for alternatives. As such, carbon dioxide (R744/CO 2 ) has come to light due to its low
