Efficiency
uses the cutting edge artificial intelligence (known as ‘fuzzy control’) to
obtain efficient operation and reduce noise.
Components fully protected from the elements
1. Electrical and mechanical parts are totally sealed in their enclosures.
2. Separated equipment space between compressors/control boxes, and heat
exchangers.
3. Because the electrical and mechanical parts are sealed in their own enclosures, this
makes them much more resistant to environment factors which can cause
corrosion (such as dust and rain) - thus improving the lifetime of the outdoor unit.
1. Duty-cycling function
alternates several compressors
conditionally to elongate product life span.
Alternate compressor cycling / back-up function
to meet diverse load in operation
1. inverter + constant speed 2 - inverter only
2. inverter + constant speed 3 - inverter only
3. inverter + constant speed 1 - inverter only
2. Back-up function
can accommodate back up compressor
operation when one compressor fails to raise product
reliability.
to back up when constant speed compressor 2
is out of order
1. inverter + constant speed 2 (out of order)
2. inverter + constant speed 1 (back up operation)
