Noise reduction strategies for screw compressors
The operating noise of twin-screw compressors is an important issue that may limit their scope of application. Two recent IJR papers suggest several noise reduction methods and analyse their...
Heat pump systems for HVAC in electric vehicles
Heat pump systems offer an energy efficient option for HVAC in electric vehicles. Recent studies present innovative technologies to further improve the heating and cooling performance of heat pump systems as...
Faults and energy consumption of CO2 refrigeration systems in supermarkets
Food products refrigeration accounts for the largest share of energy consumption in supermarkets. In a recent study, the most common faults in supermarket CO2 refrigeration systems were investigated,...
Alternatives to replace R404A for refrigerated transport
With about 5 million refrigerated vehicles operating worldwide, there is active research and development focusing on identifying alternatives to R404A, which is traditionally used in truck and trailer...
IIR GL2020 conference: Range of CO2 applications
Almost half of the presentations at the IIR Gustav Lorentzen conference in Kyoto focused on CO2, in commercial refrigeration systems but also in many other applications. Overview of these...
