Danfoss is one of the world's leading manufacturers of scroll compressors. The main principle of Danfoss scroll compressors is to use the relative rotational motion of the dynamic and static scroll teeth to form a continuous change in the closed dead volume to achieve the purpose of gas compression, which is widely used in air conditioning, heat pumps and refrigeration systems. Danfoss scroll compressors are renowned for their high efficiency, reliability and environmental friendliness.
Case Details
Compact and lightweight: Danfoss compressors are known for their small size and light weight, and their optimised design makes them compact and can be installed directly inside the equipment, reducing installation costs and saving time and effort.
Energy efficient: The use of high energy efficiency rotary compressors and motors, compared with ordinary compressors can save more than 10% of electricity.
High efficiency ratio: The highest COP (coefficient of performance) of scroll compressors can reach 3.5, due to its continuous compression process, small heat transfer between suction and discharge, no residual gap volume, high efficiency in the application.
Wide range of applications: They can be used in central air conditioning, air cooling, heat pumps and parallel systems, etc. They are also widely used in commercial and large commercial air conditioning for systems using R22, R407C and R134a as refrigerants.
Optimised part-load efficiency: Danfoss scroll compressors with Danfoss Intermediate Discharge Valve (IDV) optimise part-load efficiency, are backward compatible and minimise redesign costs.
