As a result, no oil valve is attached. Oil is constantly returning to the AC compressor by passing through a capillary tube.
Page 306: Defrosting Operation Conditions
Processes and Functions 6. Hot Gas Defrosting Control 6-2. Defrosting operation conditions (1) Defrosting operation is performed after at least 35 minutes of total operation during heating operation. * Even in outdoor units where a total operation time of 35 minutes has not elapsed, defrosting operation will be performed if other outdoor units satisfying the conditions above start defrosting operation.
Page 307: Inter-Refrigerant System Oil Recovery Control
Processes and Functions 9. Inter-Refrigerant System Oil Recovery Control ¶ Control is performed for recovering the oil accumulated in the indoor unit, refrigerant pipes, or other locations in the system. (maximum of two minutes) Control description ¶ If the oil does not return to the original level even after the oil level reaches 0 and operation is performed for a set time, the thermostat for the outdoor unit is turned off.
Page 308: Backup Operation
Processes and Functions 12. Backup Operation ¶ Types of backup operation (1) Electrically disconnecting a unit Disconnect the inter-control unit wire from the faulty outdoor unit, and set the number of C.C.U. AD units to the number of outdoor units that are connected electrically minus one. Close the service valve of the faulty unit.
Page 309: Room Temperature Control
Processes and Functions 13. Room Temperature Control The thermostat is switched on/off by ∆T as follows. ∆T = (Room temperature) – (Set temperature) Remote control sensor Room temperature = remote control sensor detection temperature Body sensor Room temperature = (Body sensor detection temperature) – (Air-intake shift temperature*) * Shift temperature (valid only for heating) In heating mode, a temperature difference occurs between the upper part and lower part of a room.
