6.3 Defrost operation Flow Chart

1. The compressor operates heating over 25 minutes, after meeting the defrosting condition, it is permitted to enter defrosting. Defrosting process is unit-stop defrosting mode. Determining condition of defrosting is as follows: Unit-stop defrosting: (1) When outdoor ambient temperature is less than 2 , (outdoor ambient temperature-

defrosting sensor) is more than 9 , and keeping over 2 minutes, enter unit-stop defrosting.

(2) Outdoor ambient temperature >2 , pipe coil temperature <15 , , enter unit-stop

defrosting. (3) If meeting the above condition, enter unit-stop defrosting. (4) First the outdoor unit sends defrosting signal to indoor unit, after receiving signal, the

indoor unit acts according to the following condition:

a. The running fan motor of indoor unit for heating stops; the electronic expansion valve

does not change.

b. The running fan motor of indoor unit for turning off unit stops; the electronic expansion

valves of indoor unit are totally open.

(5) The defrosting action of outdoor unit:

a. The electronic expansion valves are totally open; compressor stops; 4-way valve keeps

in heating state; fan motor of outdoor unit is turned off. b. After 45 seconds, 4-way valve is closed; compressor operates in 58Hz frequency. c. After the compressor has operated in 58Hz for 30 seconds, it will operate in 120Hz.

Only after 3 minutes have elapsed in defrosting state can it quit from this operation.

(6) The condition of quitting from defrosting:

a. After entering defrosting for 3 minutes, test the temperature of defrosting sensor,

continue for 1 minute over 12 , then quit from defrosting. b. Or after continuously defrosting for over 9 minutes, then quit from defrosting. c. Discharging air pressure over 2MPaG (G stands for this pressure is piezometer

pressure), defrosting over 1 minute.

(7) Actions of indoor & outdoor unit when quitting from defrosting:

a. Compressor stops 43 seconds, fan motor of outdoor unit enter set fan speed according

to the state before entering defrosting. b. After stop 45 seconds, compressor starts, simultaneously 4-way valve enters heating. c. The open state of outdoors electronic expansion valve enters the state before entering

defrosting. d. Indoor fan speed works in anti-cool Air State. e. The open state of indoors electronic expansion valve is controlled to start adjusting

after defrosting 4 minutes.

(8) The protective treatment in defrosting:

a. Pressure switch not protected b. The protective function of any temperature sensors is cancelled. c. After finishing defrosting, discharging air temperature and adjustment of expansion

valve open state, current protection etc. work should be carried out according to the state when compressor is just turned on.

4 Electronic expansion valve control

Each indoor unit has a electronic expansion valve to control refrigerant volume. For split type indoor unit, the valve is designed in a electronic expansion valve box. Indoor unit PCB communicates with the electronic valve box PCB. For other type , the valve is in the indoor unit itself. The electronic expansion valve is controlled as follows:

refrigerant flowing direction

Tin: stands for the liquid refrigerant temperature ; To: stands for the gas refrigerant temperature

Tov: overheat temperature

Overheat temperature is preset in indoor unit PCB. In cooling mode operation ,indoor unit PCB can detect the current overheat temperature by calculating To-Tin.If the To-Tin temperature is higher than Tov, the valve volume will become larger until To-Tin= Tov. In heating

operating ,outdoor PCB will control outdoor electronic valve accordingly.

5 All indoor units must operate in the same mode. If the compressor is in heating mode, the indoor unit

is not allowed to be set in cooling mode, the outdoor unit will not accept different running mode from

indoor unit.

The compressor will start at 10Hz and running between 30Hz to 120Hz. In operation the compressor

running frequency is determined by three elements : the number of indoor units in operation , the

temperature difference of each indoor units between setting temperature and room temperature , the size of each indoor unit.

7.3 Example of repair

(1) Phenomenon: after changing the PC board of outdoor unit, do not reset. After powering on

and turning on unit, some of the indoor units can operate normally, the other indoor units

display “communication trouble with outdoor unit” Treatment: switch the unit number lock switch of outdoor unit to unlocked state, after powering on, outdoor unit will examine indoor units and automatically enter indoor units’ unit number. After about 5 minutes, switch this switch to lock state. Restart indoor units, the trouble is solved. (2) Phenomenon: indoor unit displays DC current protection Treatment: check if power module is penetrated, after changing PC board, power on to restart unit, compressor operates several minutes then stops. The DC current protection still appears. Check the compressor driving circuit of, find the compressor down-lead is short circuit because of high temperature. After changing the compressor down lead, the trouble is solved. (3) Phenomenon: after finishing installation of indoor unit, start unit to operate, find B system

can operate normally, A system compressor does not work. Treatment: when left factory, the indoor unit EEPROM was default set as joint in B system. After finishing installation, when set indoor unit number, because the unit number lock switch is always in unit number locked state, the outdoor unit will not examine indoor units. So the indoor units connected with A system can not change their default setting, their signals sent to outdoor unit are overlapped with the signals sent by indoor units of B system, which cause only B system works. After resetting indoor unit number complied with procedure, the trouble is solved. (4) Phenomenon: when cooling, make A system work solely, find A system do not work, but B

system work. Treatment: after checking, find communication wire and pipe are wrongly connected. After connecting the wire correctly, reset unit number, the trouble is solved. (5) Phenomenon: start 3 sets of indoor units in the same system, under the condition of

compressor current and discharging air temperature are not too high, the operation

frequency is low. After compressor operates, some indoor units “operation” indicators still

do not light. Treatment: it is because when setting the unit number of each indoor unit, the time interval is too short, which causes the unit numbers are set repeatedly. After resetting the indoor unit number, the trouble is solved.

do the installation work. If you do the installation work by yourself, the improper installation will cause water leakage, electric shock fire and other accidents.

l The installation work shall be in line with what the installation manual specified. If

installation is not proper, water leakage, electric shock, fire and other accidents will occur.

l Install the air conditioner to a place where can definitely stand its weight. Places not firm

enough will cause drop down of unit resulting in body hurt.

l The installation work shall be preventive to typhoon and earthquake. If the installation

Item

work is not met with the requirements, overturn of the unit will occur resulting in accidents.

l The wiring work shall be done by a qualified person and referred to the “technical

standard of electric equipment”, “indoor wiring regulation” and what the manual specified. Do use special circuit. If the capacity of the circuit is not enough or bad work, electric shock, fire and other accidents will happen.

l Using the specified cable to do wiring work and connecting firmly and properly. Fix the

connecting part of the terminals to prevent it from the external force. Improper connection and fixing will cause heating and fire etc. accidents.

l Wiring shall be kept in correct shape avoiding extrusion. After installation, the electric

box cover and the external panel shall not nip the wire. Improper installation will cause heating and fire etc. accidents.

l When setting or moving the air conditioner do not let the air and things alike get into the

refrigeration system except the specified refrigerant (R22). If air and other things enter, abnormal high pressure will occur, which easily cause break and body injuries etc. accidents.

l When installing, do use the accessories or specified parts. If not using the parts specified

by our company, water leakage, electric shock, fire and refrigerant leakage will occur.

l Do not lead the drainpipe to drain where the sulfur gas may be involved. Otherwise, the

poisonous gas will enter into the indoor.

l During installation, if refrigerant leakage occurs, do the ventilation work immediately. As

soon as the refrigerant gas meets fire, poisonous gas will be produce. If the refrigerant gas enters into room and meet the air blowing heater, heater or stove etc. fire source, the poisonous gas may be produced. After installation, confirm there is no leakage of refrigerant.

l Do not install the unit in a place where the combustible gas may be leaked. In any case

the combustible gas leaks and accumulated around the unit, fire accident will occur.

l Do heat insulation work to the refrigerant gas pipes and liquid pipes to reach the purpose

of heat preservation. If the heat insulation measure is not sufficient, water generated by condensing dew will drip leading to wet the floor and indoor articles.

l Do not damage the power line or change it arbitrarily to avoid occurrence of fire or

electric shock.

l Do not extend the power line or using other electric appliance in the same power

receptacle to avoid fire or electric shock.

Note

l Do grounding work. Do not connect the grounding wire to gas pipe, tap, lighting rod or

telephone line. Improper grounding will cause electric shock.

l In some places the electric leakage breaker shall be installed. If do not install the breaker,

electric shock may occur.

l After installation, power on to do electric leakage detecting test.

During installation, if refrigerant

leakage occurs, take ventilation

measurement immediately.

As soon as the leaked refrigerant

gas meets fire, poisonous gas will

generate.

After finishing installation, confirm

the refrigerant gas does not leak.

If the refrigerant gas leaks in the

room, once it meets heater, burner

and gas stove etc. fire source, the

poisonous gas will generate.

A. Choosing of pipes
