Insufficient Refrigerant
1. Symptoms seen in refrigerating cycle
- Both
LO
and
HI
pressure side (1), (2) pressures too low.
LO
pressure side (1) : 0.05 to 0.10 MPa
(0.5 to 1.0 kgf/cm
2
, 7.1 to 14.2 psi)
HI
pressure side (2) : 0.69 to 0.98 MPa
(7 to 10 kgf/cm
2
, 99.6 to 142.2 psi)
- Bubbles seen in sight glass.
- Air discharged from air conditioner sightly cold.
2. Probable cause
- Gas leaking from some place in refrigerant cycle.
3. Solution
- Check for leakage with electric gas leak tester (refer to “[1]
HANDLING OF SERVICE TOOLS” in this section) and repair.
- Recharge refrigerant to the proper level. (Refer to “(4)
Checking Charge Refrigerant Amount” in this section.)
W1016070
Excessive Refrigerant or Insufficient Condenser Cooling
1. Symptoms seen in refrigerating cycle
- Both
LO
and
HI
pressure side (1), (2) pressures too high.
LO
pressure side (1) : 0.20 to 0.35 MPa
(2.0 to 3.5 kgf/cm
2
, 28.4 to 49.8 psi)
HI
pressure side (2) : 1.96 to 2.45 MPa
(20 to 25 kgf/cm
2
, 284.5 to 355.6 psi)
2. Probable cause
- Overcharging refrigerant into cycle.
- Condenser cooling faulty.
3. Solution
- Clean condenser. (Refer to “7-[5] CHECK POINTS OF
EVERY 200 HOURS" at "G. GENERAL” section.)
- Adjust air conditioner belt to proper tension. (Refer to “7-[5]
CHECK POINTS OF EVERY 200 HOURS” at “G.
GENERAL” section.)
- If the above two items are in normal condition, check refrigerant
quantity. (Refer to “(4) Checking Charge Refrigerant Amount”
in this section.)
NOTE
Q
• If excessive refrigerant is to be discharged, loosen manifold
gauge LO pressure side valve and vent out slowly.
