When indoor rated total capacity exceeds the outdoor rated capacity, cannot ensure that each indoor unit actual running capacity could reach its value required by rated capacity. For MC-E28AI, MC-E36AI, MC-E42AI it is not allowed to install one indoor unit only.

If the specification of outdoor unit gas va lve is 3/8, but curstomer needs to install 18 indoor unit so that it is need to use a “pipe joint subassembly” to make a conversion joint with outdoor unit gas valve and connection pipe.

5 PIPING DIAGRAM

Schematic Diagram of MULTI COMBI

The outdoor and indoor units start to work once the power is switched on. During the cooling operation, the low temperature, low pressure refrigerant gas from the heat exchanger of each indoor unit gets together and then is taken into the compressor to be compressed into high temperature, high pressure gas, which will soon go to the heat exchanger of the outdoor unit to exchange heat with the outdoor air and then is turned into refrigerant liquid. After passing through the throttling device, the temperature and pressure of the refrigerant liquid will further decrease and then go the main valve. After that, it will be divided and go to the heat exchanger of each indoor unit to exchange heat with the air which needs to be conditioned. Consequently, the refrigerant liquid become low temperature, low pressure refrigerant gas again. Such a refrigeration cycle goes round and round to achieve the desired refrigeration purpose. During the heating operation, the four-way valve is involved to make the refrigeration cycle run reversely. The refrigerant radiates heat in the heat exchanger of the indoor unit (so do the electric heating devices) and absorb heat in the heat exchanger of the outdoor unit for a heat pump heating cycle so as to achieve the desired heating purpose.

2.1.3 Heating Mode

a. Heating conditions and process: When one of the indoor units reaches the heating operation condition, the unit starts heating operation.

b. Stop in heating operation:

a) When all the indoor units reach the stop condition, the compressor stops and the outdoor fan stops after 1min;

b) Some of the indoor units reach the stop condition The compressor reduces the frequency immediately and operates according to the required frequency;

c) Heating mode transfers to cooling mode(dry mode), fan mode

The compressor stops;

The outdoor fan stops after 1min;

The status of 4-way valve: energized;

c. Outdoor fan control in heating mode

The outdoor fan starts before 5s of the starting of compressor and then it will run in high speed for 40s; The fan shall run at every speed for at least 80s; When the compressor stops, the outdoor fan stops after 1min.

d. Defrosting function

When the defrosting condition is met, the compressor stops; the electronic expansion valve of all indoor units open in big angle; the outdoor fan stops after the stop of the 4-way valve, meanwhile, the 4-way valve reverses the direction; after the 4-way valve reverses the direction, the compressor starts; then begin to calculate the time of defrosting, the frequency of the compressor rises to reach the defrosting frequency.

e. Oil-returned control in heating mode

a) Oil-returned condition

The whole unit is operating in low frequency for a long time

b) Oil-returned process in heating mode

Page 22

2.1.4 Fan Mode

The compressor, the outdoor fan and the 4-way valve are closed; temperature setting range is 16～30℃.

2�2 Protection Function

2.2.1 Mode Conict Protection of indoor unit

When the setting mode is different of different indoor unit, the unit runs in below status:

a. The mode of the rst operating indoor unit is the basic mode, then compare the mode of the other indoor units to see if there is a conict. Cooling mode (dry mode) is in conict with heating mode.

b. Fan mode is in conict with heating mode and the heating mode is the basic mode. No matter which indoor unit operates rst, the unit will run in heating mode.

2.2.2 Overload Protection Function

When the tube temperature is a little low, the compressor raises the operation frequency; when the tube temperature is a little high, the compressor frequency is restricted or lows down the operation frequency; when the tube temperature is too high, the compressor protection stops running. If the discharge temperature protection continuously appears for 6 times, the compressor can’t resume running. The compressor can resume running after cutting off the power and then putting through the power. (if the running time of the compressor is longer than 7min, the protection times record will be cleared)

2.2.3 Discharge Protection Function

When the discharge temperature is a little low, the compressor raises the operation frequency; when the discharge temperature is a little high, the compressor frequency is restricted or lows down the operation frequency; when the discharge temperature is too high, the compressor protection stops running. If the discharge temperature protection continuously appears for 6 times, the compressor can’t resume running. The compressor can resume running after cutting off the power and then putting through the power. (if the running time of the compressor is longer than 7min, the protection times record will be cleared)

2.2.4 Communication malfunction

Detection of the quantity of installed indoor units: After 3min of energizing, if the outdoor unit does not receive the communication data of certain indoor unit, the outdoor unit will judge that indoor unit is not installed and will treat it as it is not installed. If the outdoor unit receives the communication data of that indoor unit later, the outdoor unit will treat that unit as it is installed.

2.2.5 Compressor high-pressure protection

a. When the high-pressure switch is detected cut off for 3s continuously, the compressor will enter high-pressure protection as it stops when reaching set temperature. Meanwhile, the outdoor unit will send the signal of “high-pressure protection” to the indoor units;

b. After the appearance of high-pressure protection, when the high-pressure switch is detected closed for 6s continuously twice an hour, the compressor can resume running only after cutting off the power and then putting through the power.

2.2.6 Compressor low-pressure protection

a. Low Pressure Protection for Shutdown

After the compressor stops for ve minutes, if it is detected that the low pressure protection switch is opened, then a

low pressure protection signal will be send out.

If it is detected continuously for three seconds that the low pressure protection switch is opened after the compressor stops for less than five minutes, then a low pressure protection signal will be send out. However, if the low pressure protection occurs twice in one hour, then it becomes unrecoverable and has to be recovered by powering the outdoor unit again.

b. Low Pressure Protection during the Operation

a) When it is detected continuously for three seconds that the low pressure protection switch is opened, then the whole unit should be shut off and a low pressure protection signal should be sent to the indoor unit.

Page 23

CONTROL

b) On condition that a low pressure protection error occurs and the whole unit has stopped for more than three minutes and it is detected continuously for six seconds that the low pressure protection switch is closed, then this error can be eliminated. However, if the low pressure protection occurs twice in one hour, then it has to eliminate the error by powering the outdoor unit again.

2.2.7 Compressor overload protection

If the compressor overload switch is detected having movement, the indoor unit will display the corresponding malfunction as it stops when the indoor temperature reaching set temperature. When the compressor stops for more than 3min and the compressor overload switch is reset, the unit will resume operation status automatically. If the protection appears for more than 6 times (if the running time of the compressor is longer than 30min, the protection times record will be cleared), the unit can not resume operation status automatically, but can resume running only after cutting off the power and then putting through the power.

2.2.8 Drive Error

When the system is powered on and starts to run for the rst time, let all indoor units on line run under the “Fan”

mode, and they will go to the piping test through the preset mode after they has run at the high fan speed for six minutes.
