2. Periodical check
Qualify Standards (Settlement)
Judge whether there is abnormal sound by
hearing;
Watch from one meter
away from the center of
the unit;
Watch whether the swings of distribution pipes
and components are too large
Rating voltage is within ±10%
Insulation material
flakes
Check whether the exhaust water pipe blocks
Whether there is abnormal sound when starts
up, runs or stops
Above 5MΩ is required when testing with
DV500V high resistance meter
Hock proof rubber
gets old
Flexible when pressed with hands is qualified
Pay attention to the noise libation and oil level
Confirm the action of safety device and
protection device
Normal wind amount, high pressure when
refrigerating and low pressure when heating
within the normal range
Normal wind amount, high pressure when
refrigerating and low pressure when heating
within the normal range
Shell land tube
heat exchanger
Water flow of the
user side
Within ±5% of the standard
Make sure it is set above the concentration
Refer to the physical
characteristics of
cold-resistance liquid
Refer to water quality
furring relations drawing
The low pressure is within the standard when
refrigerating
The high pressure is within the standard when
heating
Drain all the water if it is not used for a long time
Drain water in the
distribution pipe
High and low
pressure switch
Check according to “Protection Devices Action ‘
Whether the match
point is good
Compare with correct pressure gauge
Smooth action on globe valve switch
Check whether there is refrigeration media
leakage inside the unit or at the distribution pipe
connecting points. Let out all the water inside the
shell-and-tube heat exchanger, and check
whether there is any leakage at the water inlet or
outlet.
Use the electronic leak
detector, or blowtorch
leak detector, or soap
water.
Electrical
machine control
Above 1MΩ is required when testing with
DV500V high resistance meter.
Insulation layer of the wire must be under good
contact condition, without damage, bolt well
fixed.
Act according to the time set
