High-head condition setting
▪
Purpose
Secure performance and reliability when using units installed under a high-head condition.
▪
Concept
-
Control of the compressor frequency, outdoor fans, EEV, and valves is optimized to facilitate the circulation of
refrigerant in any head condition.
▪
Control specifications in detail
- In Type 1 heating mode, the initial EEV opening degree increases.
The compressor frequency increase speed decreases if the low pressure is low
(see "Main EEV control" for details on EEV control).
- In Type 2 heating mode, the initial EEV opening degree decreases.
The compressor frequency increase speed decreases if the low pressure is low
(see "Main EEV control" for details on EEV control).
- In Type 2 cooling mode, the target high pressure for outdoor fans increases to 28kgf/cm2,g.
(see "Fan control" for details on controlling outdoor fans).
- In Type 1 and 2 cooling modes, EVI bypass mode turns on (see "EVI EEV control" for details).
