CAUTION
If gauge needle does not move from 0 cmHg (0 MPa) to 76 cmHg (0.1 MPa), in step 3 above take the following measure:
· If the leak stops when the piping connections are tightened
further, continue working from step 3.
· If the leak does not stop when the connections are
retightened, repair location of leak.
· Do not release refrigerant during piping work for installation
and reinstallation. Take care of the liquid refrigerant, it may cause frostbite.
2) Any leak detected at this level shall be repaired and retested, starting from “Step 1: Pressure test”.
NOTE: – Always recover the refrigerant and Nitrogen gas into recovery
cylinder after completion of a test. – You must use the detection equipment with Detectable Leak Rate
of 10-6 Pa.m3/s or better. – Do not use refrigerant as test medium for system with total
refrigerant charge more than 5kg. – Test shall be performed with dry Nitrogen or another non-
flammable, non-reactive, dried gas. Oxygen, air or mixtures containing them shall not be used.
AIR-TIGHTNESS TEST ON THE REFRIGERATING SYSTEM
Before system charged with refrigerant and before the refrigerating system in put into operation, below site test procedure and acceptance criteria shall be verified by the certified technicians, and/ or the installer:-
Step 1: Pressure test for refrigerant leak detection:
1) Steps for pressure test, in accordance to ISO 5149. 2) Evacuate the system from refrigerant before the leak test, attach
the gauge manifold set correctly and tightly. Charging hose of Low side connect to Gas side. (Charging hose of High side connect to Liquid side if applicable.) 3) Adjust the knob on the service valves, and regulator on the gauge set, so that test gas can be inserted through the centre manifold of the gauge set. 4) Insert Nitrogen gas into the system through the centre manifold and wait until the pressure within the system to reach about 1MPa (10 BarG) wait for a few hours and monitor the pressure reading on the gauges. 5) Please note that the system’s pressure may rise slightly if the test is carried out on mid day, due to temperature rise. The inverse may happen when there is temperature drop at night. However, this variation will be minimal. 6) Waiting time depends on the size of the system. Larger systems may require 12 hours of waiting time. Leak detection within smaller system can be achieved in 4 hours. 7) Check if there is a constant pressure drop. Move to next step “Step 2: Refrigerant leak detection…” if there is any pressure drop. Otherwise, release the Nitrogen gas and, move to “Step 3: Vacuum test”. 8) Next, insert a small amount of same refrigerant into the system through the centre hose, until the pressure reaches about 1MPa (10 BarG).
(Low/Gas) pressure gauge
(High/Liquid) pressure gauge
Step 3: Vacuum test:
1) Perform Vacuum test to check leak / moisture if present. 2) Refer to section “EVACUATION OF THE EQUIPMENT” to
vacuum gas out of the air conditioning system. 3) Wait for a few hours, depending on the size of the refrigerating
system and monitor the pressure rise. If the pressure rises until 1 bar absolute, then there is leak. If the pressure rises, but it is lower than 1 bar absolute, then moisture is present.
Next, remove the moisture, or repair, and redo the refrigerant leak testing, starting from “Step 1: Pressure test”.
