High Load Prevention Control(During Heating)
4-2. High Load Prevention Control (During Heating)
4-2-1. Operation Pattern
4-2-2. Operation specification
Œ
Prevention control of high temperature according to the outdoor temperature
– Outdoor temperature ≥ 14˚C : Outdoor FAN LOW
– Outdoor temperature ≤ 12˚C : Outdoor FAN HIGH
´
Prevention control of high temperature according to the indoor heat exchanger temperature
– Outdoor fan / COMPor is controlled by detecting the indoor heat exchanger during control of outdoor fan according to the outdoor
temperature.
– Indoor heat exchanger temperature ≥ 60(58)˚C : Outdoor FAN OFF(high temperature prevention 1st)
– Indoor heat exchanger temperature ≥ 65˚C for 20 seconds : Outdoor FAN OFF, compressor OFF
– Release of the high temperature control based on the indoor heat exchanger
! The 1st release of high temperature prevention
!
→ Release at outdoor temperature ≥ 14˚C: indoor heat exchanger temperature ≤ 55(52)˚C((
!
→ Release at outdoor temperature ≥ 12˚C: Indoor heat exchanger temperature ≤ 52˚C
@ The 2nd release of high temperature prevention
!
→ Release at indoor heat exchanger temperature ≤ 52˚C
ˇ
Indoor fan control at the control of high temperature prevention
– Indoor fan control during 1st high temperature prevention
– → breeze is set at wind volume → weak, weak → weak, strong → strong
– → In model 23Z, strong wind at outdoor temperature ≥ 14˚C, the temperature of indoor heat exchanger ≤ 55˚C
– Indoor fan control at the 2nd high temperature prevention : breeze
