- Oil return operation 93
- Oil return operation in cooling operation 93
- Special operation 93
- Starting conditions start oil return operation in cooling operation referring to the following conditions cumulative oil return amount timer cumulative compressor operating time after power supply turns on exceeds 2 hours and the time after the completion of previous oil return operation exceeds 8 hours furthermore the cumulative oil return is calculated according to tc te and compressor load 93
- Oil return operation in heating or cooling heating simultaneous operation 94

- S2 1 water heat exchanger is an evaporator 95
- Cooling operation mode 96
- If any liquid refrigerant remains in the heat exchanger during compressor startup the liquid refrigerant will enter the compressor resulting in the dilution of the refrigerating machine oil in the compressor and the degradation of lubricating capacity therefore before the compressor stops pump down operation is performed to collect the refrigerant in the heat exchanger 96

- When the superheated at the evaporator outlet degree is large open the solenoid valve svg for venting receiver gas of the outside units that are running out of gas 98
- When the superheated degree at the evaporator outlet is large open the solenoid valve svg for venting receiver gas of the outside units that are running out of gas and the solenoid valve svl for pressurizing the receiver of the excessively charged outside units 98
- After oil return operation 99
- At the beginning of the starting control 99
- Details of outside unit rotation in the case of multi outside unit system each outside unit is given an operating priority for the control outside unit rotation makes it possible to change the operating priority of outside units thus the system becomes free of compressors that stop over an extended period of time at the time of partial loading preventing unbalanced oil level 99
- Example the following diagram shows outside unit rotation in combination of 3 outside units 99
- In the case of multi outside unit system this outside unit rotation is used to prevent the compressor from burning out due to unbalanced oil level between outside units 99

- About refrigerant r 410a 327
- Characteristics of new refrigerant r 410a 1 performance almost the same performance as r 22 and r 407c 2 pressure working pressure is approx 1 times more than r 22 and r 407c 3 refrigerant composition few problems in composition control since it is a quasi azeotropic mixture refrigerant 327
- Non azeotropic mixture refrigerant mixture of two or more refrigerants having different boiling points 327
- Outline 327
- Precautions for new refrigerant r 410a 327
- Quasi azeotropic mixture refrigerant mixture of two or more refrigerants having similar boiling points 327
- The design pressure is different at each product please refer to the installation manual for each product reference 1 mpa 10 9716 kgf c 327

- As for the charge mouthpiece and packing 1 2unf20 is necessary for mouthpiece size of charge hose 330
- Copper tube material and thickness 330
- O soft annealed h hard drawn 330
- R 410a is used under higher working pressure compared to previous refrigerants r 22 r 407c furthermore the refrigerating machine oil has been changed from suniso oil to ether oil and if oil mixing is occurred sludge results in the refrigerants and causes other problems therefore gauge manifolds and charge hoses that are used with a previous refrigerant r 22 r 407c can not be used for products that use new refrigerants be sure to use dedicated tools and devices 330
- Service tools 330
- Tool compatibility 330
- Change of dimension a 331
- Conventional flaring tools can be used when the work process is changed change of work process previously a pipe extension margin of 0 to 0 mm was provided for flaring for r 410a air conditioners perform pipe flaring with a pipe extension margin of 1 to 1 mm for clutch type only conventional tool with pipe extension margin adjustment can be used 331
