Air-conditioning System

AC-2Air Conditioning System
Introduction
In case the liquid refrigerant enters into the eye or touches the
skin, the following measures shall be taken:

Wash the part where is touched by the refrigerant with a
great deal of water.

Coat the skin with the clean Vaseline.

See the doctor or go to the hospital for treatment; and

Do not try to cure it yourself.
General Introduction
1. Take notice when handling refrigerant General Introduction
(a) Do not handling with refrigerant in the closed room or
near to open fire.
(b) Safety goggles shall be worn when handling
(c) Be careful to avoid the liquid refrigerant from entering
into your eye or touching you skin.
waterair
dust
ÅçåÇÉåëÉêplug
2. Take notice when changing the parts of refrigerant pipes:
(a) The refrigerant shall be exhausted gradually before
changing.
(b) The dismantled parts shall be covered with plug right
away so as to prevent the water or dust from entering into
the system.
(c) Do not store the condenser or liquid tank under the
condition that the plug has been uncovered. and
(d) Refrigerant shall be exhausted before installing the new
condenser, because the refrigerant, if not exhausted, will
eject out in gaseous form with the lubricant oil when the
plug is moved away.
3. Take notice when fastening the connection parts:
(a) Spread a little lubricant oil at the matching position of the
O-type ring to fasten the connection and avoid of gaseous
refrigerant leakage.
(b) Fasten the nut with two spanners so as to avoid of the pipe
deformation.

AC-3Air Conditioning System
Introduction
(c) Tighten the O-ring matching position or the threaded position
to the specified moment.
4. Take notice when connecting measuring meter at branch pipes:
(a) Connect the end of filling hose with high speed joint to the
filling valve of compressor.
(b) Letter
D
marked on the compressor near the auxiliary valve
represents the side of high voltage while
S
means the side of
low voltage, which shall be looked out when connecting the hose.
(c) Fasten the bolts by hand, and
(d) In order to prevent the hose from loosing, lubricant oil shall not
be spread at the connection position.
Remarks: after connecting the measuring meter on branch pipes to
the refrigerant container (repairing tank), the air in the hose shall be
exhausted up.
5. Take notice when vacuumizing:
After vacuumizing for 20 min, maintain the container at certain
pressure to ensure that all air in it is exhausted up, and another
inspection shall be made to see whether there is leakage.
6. Take notice when handling with the refrigerant container
(repairing tank):
(a) Do not heat it.
(b) Store the container at the place where temperature is under 40

(c) In case of heating the repairing tank with hot water, care shall
be paid to the valves at the top of tank, do not dip them into the
water, or the water will penetrate into the cooling system.
(d) The empty repairing tank is forbidden to reuse.
8. Take notice when using the high-pressure air cylinder type
inspecting device:
(a) In case the open fire is used, it is the first to ensure before using
there is no flammable material around.
(b) Be careful because toxic gas will be produced when the
gaseous refrigerant meets with the open fire. 7. Take notice in the A/C operation or when adding the liquid
refrigerant:
(a) In case the gaseous refrigerant in the cooling system is
insufficient, which can lead to the compressor burns out, and
such accidents shall be avoided.
(b) If the valve on the side of high pressure is uncovered, the
refrigerant will flow in the reverse direction, which may lead
to the break of the repairing tank, therefore, only valves on the
side of low pressure are allowed to open or closed.
(c) If the repair tank is laid in reverse direction, and the refrigerant
is added in liquid status, the liquid refrigerant will be
compressed, which may lead to failure of the compressor,
therefore, refrigerant shall be inflated in the gaseous status.
(d) Be careful not over-inflate the gaseous refrigerant, otherwise,
such failures as insufficient cooling, increase of oil consuming
or over heat of engine will be followed.
