6 MPS Variable Multi Split System(50Hz, R410A)
Features & Benefit
MPS(Multi Power System) Variable Control : (Except A2UC146FA0,A2UH146FA0)
Big Energy Saving with MPS Variable Control
• Basic Principle of MPS Variable Control
MPS control provides comfortable and convenient environment as there are two compressors with 60&40%
load sharing with on compressor of small capacity always working to maintain the set temperature conditions &
meanwhile other compressor is at rest if the load is low whereas in conventional system the only compressor is
working with ON/OFF cycles.
• Power Consumption Comparison
MPS Veriable Multi system opeates in one cycle with two compressors.
Only one compressor or two compressors run together, according to the load conditions.
With small load. only one compressor completes the cycle. It saves power consumption at low operation. This
concept is explained in the picture below.
