The service rules of the R407C product

The service rules of the R410A product

1. The service rules of the new refrigerant R407C product

COOLWEX uses the green refrigerant R407C firstly in China.
Its thermal characters are similar to R22, but there is little difference between them.

1.1 The main difference between R407C and R22:

R407C R22
Component HFC32/125/134a HCFC22
The ratio of mix Wt％ 23/25/52 100
The saturation liquid density Kg/m

3

1136 1191
Normal pressure kj/kg.k 0.835 0.622 Specific heat
The saturation liquid kj/kg.k 1.554 1.256

Evaporating pressure kpa 499 498
Condensing pressure kpa 2112 1943
Temperature slippage ℃ 4.3-7.1 0
Heating capacity w 92-97 100
Input power w 106 100
COP 97 100
The consistent with the oil Fat oil Mineral oil

1.2 Service precautions:

1.2.1 Because R407C is a mixture composed of three kinds of matter, when vapor phase and liquid
phase coexist, the component of the vapor phase is different from the liquid phase. When we fill
the refrigerant, we must ensure to fill it in liquid phase, in order to maintain the stability of the
character.

1.2.2 The leakage of the refrigerant is from vapor side or liquid side, and the leakage from vapor side
could make the component change and impact the character seriously. So when the amount of
the leakage is up to 5%, we need discharge all refrigerant in the system, and fill liquid
refrigerant according to amount in nameplate.

1.2.3 Because the lubricant fit for refrigerant R407C is ester refrigerating engine oil (POE) or ether
refrigerating engine oil (PVE). The mineral lubricant fit for refrigerant CFC and HCFC is weak in
consistent with the HFC, and it doesn’t fit for the refrigerant HFC. So when the compressor
using new refrigerant R407C is worn out, to replace it by compressor of CFC or HCFC is
forbidden.

1.2.4 When the connection of the refrigerant pipe is finished, before the system start up we should
vacuum the indoor unit by cut-off valve or discharge the indoor unit air by refrigerant R407C
bottle. Discharged the air in system by outdoor unit refrigerant is forbidden.

1.2.5 Ester oil could adsorb the water in the air. In order to removemoisture in refrigeration system,
avoid capillary jammed by ice and the ester lubricant oil decomposed with water, we use
desiccant in system. Artificial zeolite (molecular sieve R etc.) is the effective water sorbent.
Toavoid absorb refrigerant but only absorbmoisture, we use the molecular sieve whose
aperture is smaller than the molecule of the refrigerant. For R407C we should adopt XH-11
rather than XH-9AK and 4A-NRG.

1.2.6 Because the corrosion of R407C and POE to high molecular material is different from R22 and
mineral oil, the airproof material inside high/low pressure valve and foul-way valve needs to be
changed in refrigeration system, such as R407C, polyurethane rubber etc. The high/low
pressure valve and four-way valve which are fit for R22 couldn’t be used in service.

1.2.7 When there is leakage, filling with other kind of refrigerant is forbidden.

1.2.8 When we need to vacuum the system, we should use the special quick joint, but use the quick
joint of other refrigerant is forbidden lest pollute by mixing refrigerant. The time for vacuuming is

5

about 30 minutes, and vacuity is less than 133Pa.

1.3 Precautions:

1.3.1 Regulations

Being liquefied vapor, R-407C and R-410A are high-pressure vapor , the high-pressure gas regulation is
applicable. Before use it, please refer to high-pressure gas regulation. To prevent the high-pressure
vapor from causing damage, the regulation should be followed.

1.3.2 Usage of vessel
Being high-pressure vapor, R-407C and R-410A are contained in high-pressure vessel. The
safety condition of vessel is good, but if you don’t use it carefully, you may damage the vessel
and cause accident.

1.3.3 Storage
Although R-407C and R-410A are nonflammable, when they are stored with the normal
high-pressure gas, we should place them in the good ventilation area.
In addition, there are safe devices in the high-pressure vessel. Please note that when the
temperature (fusible valve) or pressure (spring safe valve) is up to a certain value, it will eject
vapor.

1.3.4 Ventilation
Because R-407C and R-410A are heavier then air, they will go down. If room is full of the
leakage vapor, the density of oxygen will decrease, and cause people suffocated.
In addition, if you light the fire when there is R-407C in the air, it will produce the toxic gas with
pungent odor and corrosiveness.

1.3.5 Precautions about health
For R-407C, R-410A and normal liquefied high-pressure vapor, please don’t contact with skin
directly, and prevent being splashed into eyes and avoid drinking.

1.3.6 The following are the urgent disposal methods:
Splash into eyes:
Wash eyes with pure water for more than 15 minutes, and don’t knead the eyes or blink.
Please wash eyes with watery boric acid water if the ache gets heavy.
To avoid the accident, please ensure that you wear the protection glasses.
Contact with skin directly
The temperature will decrease rapidly by evaporation if R-407C and R-410A expose to air in
liquid phase. So if the liquid contacts with skin directly, it may cause frostbite. If there are freeze
burns, please go to see the doctor immediately.

2. The service rules of the R410A product

2.1 There are some differences between air conditioner of R410A s and that of R22:

2.1.1 The compressor used is different, it is a new refrigerant compressor (special);

2.1.2 The air conditioner of new refrigerant R410A has a drier, while the A/C of R22 doesn’t have.

2.1.3 There is no difference between the evaporator, condenser and system pipe of new refrigerant
R410A A/C and that of R22 A/C in appearance. The requirement of new refrigerant R410A A/C
for craft is higher , and the amount of moisture and impurity in the system is less than that of A/C
using R22. The resistance to pressure is higher.

2.1.4 The manufacture process is different, the requirement of air conditioner using R410A for craft is
high.

2.2 Refrigerant system:

2.2.1 The high pressure of refrigerant system is 3.0 Mpa, and the low pressure is 1.2 Mpa. (The
value is 1.5 times more than that of R22 under the same condition)

2.2.2 When installing the split type of new refrigerant R410A, all connecting pipes must be special
pipes of R410A. Discharging air must use refrigerant R410A, and couldn’t misuse the
connecting pipe and refrigerant of A/C using R22. Otherwise, it will destroy the stability of A/C.

2.2.3 Because the compressor of refrigerant R410A split type uses POE oil, which can react with
moisture to form water and acid. The water produced by reaction could react further, and if the

6

chain reaction proceeds continually , the water in the system will be more and more. It will cause
the capillary ice blocking; at the same time, acidity of working substance circulated in the
system will be higher and higher (the value of PH is lower and lower), and it may corrode the
components and parts in the system. The phenomenon of copperizing would happen. When
installing A/C, the action should be prompt, and after opening the plug of connecting pipe we
must tighten the nut in 5 minutes. The time of discharging air should be enough. When
installing A/C, the sweat drops into the connecting pipe is forbidden; the infusible impurity
mixed in the system is forbidden. It is better to install the A/C of refrigerant R410A split type in
fine weather, do not do it in rainy day, nor humid weather.

2.2.4 The chlorine ion could react with POE oil to form acid, and the acid corrodes the components
and parts of refrigerant system. So pollute the system with chlorine ion in installation is
forbidden, such as sweat beads and other impurities that contain chlorine ion.

2.2.5 Whatever the reason we must change the drier, if the refrigerant system is exscinded in service,
after we exscind the refrigerant system, we must use something to wrap the fracture lest the
moisture in air enters into the system. The time that refrigerant system expose to air should be
less than 5 minutes.

2.2.6 Must weld the drier into system in 5 minutes in order to isolate the air when changing it.
Otherwise it will influence the performance of the drier.

2.2.7 Must use special pump after service. The lubricant should be the grease. The pump couldn’t be
used to vacuum the A/C of refrigerant R22, otherwise it would cause the contamination of
refrigerant, and influence the performance of A/C. The time of vacuuming must be over 25
minutes, Otherwise the moisture in system will be too high, and affect the stability of A/C.

2.2.8 If need to change the components and parts, must use the special one of R410A in service.
Using the components and parts of R22 is forbidden; otherwise it would affect the stability of
A/C.

The refrigerant R410A should be placed in environment under 30℃. If the refrigerant has been
placed in environment above 30℃, it is necessary to store the refrigerant in the environment below
30℃ for more than 24 hours. Otherwise the component of refrigerant would be changed and it
affects the performance of A/C.

8.7.3 Low room temperature protection:

When room temperature decreases to below 10℃, compressor and outdoor fan will stop(indoor fan
is Breeze). Dehumidifying operation will be resumed when room temperature restores to over 13℃.

8.7.4 At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same as that

of cooling mode.

8.8 Heating mode

8.8.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 4-way valve

must delay 2 minutes compared with compressor if the compressor changed into non-heating mode

or turned off. 4-way valve doesn't delay in dehumidifying mode.

8.8.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except

for the defrosting mode or the end of defrost.

8.8.3 Action of compressor and outdoor fan motor at heating mode: compressor must run for 7 minutes

after starting and then judge temperature. Meanwhile other protections are still valid.

8. Electric Control Functions

8.1 Control system

The control system adopts modular design, that is, all indoor units communicate with outdoor units, ref. to the
following figures for the control structure between indoor units and outdoor units. In the structure, the indoor control
board receives the information from users (for exam. set temp., fan speed etc.) and environment (ex, indoor coil
temp., indoor temp. etc.) ,and organize it to control the action of relevant parts, then transmits the signals to outdoor
control board through the following communication circuit. Outdoor control board can deal with the information
from indoor unit and figure out the best running mode, then transfer the instruction to indoor units to carry out it.
Indoor unit receive the user’s remote control signals.

8.2.2 AC Amp Protection
The outdoor control board checks the compressor current and do over-current protection.
If the compressor current is over the scheduled value, the system will stop and all indoor units will display
malfunction code.

Note: 1. In order to prev ent prot ection due to too big LRA when compressor starts, the outdoor control board begins

to check the compressor current after 10 seconds.

2. If current protection happens, the compressor will stop and restart 3 minutes later.

8.2.3 High-pressure Protection and Low-pressure Protection

211

The High-pressure switch and Low-pressure switch are installed at suction pipe and discharge pipe separately. And
users can select to install. Normally, the high-pressure switch is cut down when higher than

425Psi (3.3Mpa Cut
down, 2.4Mpa Resume). While the low-pressure switch is cut down when lower than 7Psi (0.05Mpa
On, 0.15Mpa Resume).
Under high-pressure protection or low-pressure protection, the compressor will stop and restart 3
minutes later.

8.2.4 Outdoor Unit communication protection

8.2.4.1 Communication protection between indoor unit and outdoor system chip
If the outdoor unit can’t receive the indoor signal for 30 seconds, then the indoor units are judged as no starting and
there is no alarm signal. If the indoor units send signal to system chip for 2 minutes and no feedback signal is
received, then judge as communication malfunction.

8.2.4.2 Communication protection between outdoor system chip and inverter chip
If can’t receive signal or receive wrong signal for over 2 minutes, Indoor/Outdoor Unit stops operation. When the
signal is right, Indoor/Outdoor Unit restarts.

8.2.5 Outdoor condenser high temperature protection
Under cooling mode, if

T3〉65℃ for 3 minutes, the compressor will stop. When T3〈52℃, the protection
is not valid.
When protection is released, the compressor restarts 3 minutes later.

8.2.6 Temperature Sensor short/open protection
When the outdoor condenser pipe temperature T3, outdoor ambient temperature T4, indoor evaporator outlet
temperature

T2B are checked out of range 0.05～4.95V, it think temperature sensor short/open
protection. The compressor, four-way valve and outdoor fan motor will stop and send malfunction
signal to indoor units.
When the volt is resumed to the range 0.05～4.95V, then resume signal to indoor units and control
on-off of the compressor, four-way valve and outdoor fan motor by indoor size.

8.2.7 Outdoor low temperature protection
If the outdoor temperature is lower than -15℃ for 1hour, the compressor and fan motor will stop. And
any operation is not valid.
If the outdoor temperature is higher than -12℃ for 10 minutes and the compressor stops operation
for 1h, or the outdoor temperature is higher than 5℃ for 10 minutes, then restart and enter into the
prior operation mode.
If any indoor unit sends out this protection request, the outdoor unit will stop compressor until all
indoor units have not this protection request.

8.2.8 Compressor pre-heating function
When the outdoor temperature is lower than 3℃ and the compressor stops operation for more than 3
hours, or the outdoor temperature is lower than 3℃ and the power is just put on, the compressor
enters into pre-heating condition.
