GREE GMV5 HR HEAT RECOVERY UNITS
39
No. Installation Problem Possible Consequence
8
Incorrect amount of refrigerant is
filled.
The system cannot correctly control the flow allocation; the compressor may
be operating under over-heating environment or running when the
refrigerant flows back to the compressor..
9 The refrigerant pipe leaks.
Insufficient refrigerant circulating in the system decreases the cooling
performance of the air conditioner. Long-term operation under such
circumstance may cause an overheating compressor or even damage the
compressor.
10
Water drainage from the
condensate water pipe is not
smooth.
Residual water in IDUs can affect the normal operation of the system. The
possible water leakage can damage the IDU's decoration.
11
The ratio of slop for condensate
water pipe is insufficient or the
condensate water pipe is
incorrectly connected.
Reverse slop or inconsistent connection of condensate water pipe can
hinder the smooth drainage and cause leakage of the IDU.
12 The air channel is improperly fixed. The air channel will deform; vibration and noise occur during unit operating.
13
The guide vane of air channel is not
reasonably manufactured. Uneven air quantity allocation reduces the overall performance of the air
conditioner.
14
The refrigerant pipe or condensate
water pipe does not meet the
insulation requirement.
Water can easily condensate and drip to damage the indoor decoration, or
even trigger the protection mode of system due to overheating operation.
15
The installation space for IDU is
insufficient. Since there is a lack of space for maintenance and checking, indoor
decoration might need to be damaged during such operation.
16
The IDU or the location of the air
outlet or return air inlet is not
designed reasonably.
The air outlet or return air inlet may be short-circuited, thus affecting the air
conditioning performance.
17 The ODU is improperly installed.
The ODU is difficult to be maintained; unit exhaust is not smooth, which
reduces the heat exchanging performance or even prevent the system from
normal operation; in addition, the cold and hot air for heat exchange and the
noise may annoy people in surrounding areas.
18
Power cables are incorrectly
provided.
Unit components may be damaged and potential safety hazard may occur.
19
Control communication cables are
incorrectly provided or improperly
connected.
The normal communication in the system fails or the control over IDUs and
ODUs turn in a mess.
20
Control communication cables are
not properly protected. The communication cables are short-circuited or disconnected, and the unit
cannot be started up due to communication failure.
Understand the special requirement (if any) for unit installation before implementation to ensure
installation quality. Relevant installers must have corresponding engineering construction qualifications.
Special type operators involved in the engineering implementation, such as welders, electricians,
and refrigeration mechanics must have relevant operating licenses and are accredited with vocational
qualification certification.
3 COOPERATION BETWEEN DIFFERENT
PROFESSIONS
A quality installation of air conditioning engineering depends on careful organization and close
cooperation between different professions such as architecture, structure, electric, water supply and
drainage, fire-fighting, and decoration. Pipes must be laid in places away from any automatic spray head
for fire-fighting, and must be reasonably arranged to ensure that the pipes fit the electric, luminaries, and
decoration.
