¥ If auto fresh conditions are established when heating operation stops, defrosting operation can be executed during the stop period.
Auto fresh defrosting consists of [balancing period of 90 seconds when defrosting starts
→ reverse cycle period for 12 minutes maximum]
.
(1) Auto fresh defrosting defrosting start conditions
¥ Auto fresh defrosting is performed when all the following conditions are satisfied:
1)
Heat-exchanger at low temperature (heat-exchanger temperature
≦ DEF → ON
)
2) Units in all cycles stop
3) Auto fresh defrosting inhibit time (15 minutes) is up
4) Compressor is turned on during operation stop
5) There is a delay of compressor from indoor units during operation stop
(2) Auto fresh defrosting stop conditions
¥ Auto fresh defrosting is released when any of the following conditions is established:
1)
Heat-exchanger temperature is recovered (heat-exchanger temperature
≧ DEF → OFF
)
2) Maximum defrosting time (12 minutes) is up
3) A failure occurs
4) Either indoor unit of all cycles starts operation.
※ Release during balancing at start: To stop or start operation when remaining balancing time is up.
Release during reverse cycle period: To stop or start operation when balancing time (3 minutes) is up.
(3) Outputs during auto fresh defrosting
[Defrosting request between outdoor microcomputers] Not to be transferred.
[Indoor defrosting request] To be transferred only to object unit of auto fresh defrosting (indoor unit which has stopped last).
[Compressor] To increase the speed at the rate of DFSTEP rpm/TDFSPT second and reach the maximum defrosting speed [DEFMAX].
[Expansion valves] Non-object units of auto fresh defrosting: To be fully closed when defrosting starts and the balancing time (30 seconds) is up.
Object units of auto fresh defrosting: To be opened by [DFSPPS] pulses, synchronized whith a step-up of rotation speed, and fully opened
[DFPSMX] when the speed reaches [DEFMAX].
(4) Special remarks
¥ Other cycles should remain in the stop mode.
¥ When operation stops during defrosting, the unit should directly shift to auto fresh defrosting.
¥ All indoor units should stop for auto fresh defrosting. Therefore, if two cycles stop operation simultaneously, auto fresh defrosting will not
commence because of delay in communications.
