Only duplex cylinder compressor opens the damage into air conditioner to prevent major structure.
That is, as shown in figure 3, when the operational mode of air conditioner becomes for heating mode and temperature detection value in rising
During gesture, the 3rd temperature threshold B0 can open operation as duplex cylinder compressor is judged with single cylinder mode of operation or twin-tub mode of operation
Critical condition, the 4th temperature threshold A0 can be used as the critical condition for determining whether unlatching duplex cylinder compressor.
Further, when the operational mode of air conditioner is heating mode and temperature detection value is in downward trend, control
Module 30 can determine whether whether temperature detection value is less than the difference B0-D0 of the 3rd temperature threshold and the 3rd difference and is more than or equal to the 4th temperature
The difference A0-C0 of threshold value and the 4th difference is spent, wherein, the 3rd difference D0 and the 4th difference C0 are all higher than being equal to zero.
If temperature detection value is more than or equal to the 3rd temperature threshold and the difference B0-D0 of the 3rd difference, indoor heat exchanger
Temperature is still too high, and control module 30 can forbid duplex cylinder compressor to open；If temperature detection value be less than the 3rd temperature threshold with
The difference B0-D0 of 3rd difference and the temperature for being more than or equal to the 4th temperature threshold and the difference A0-C0, then indoor heat exchanger of the 4th difference
It has been declined that, control module 30 can allow duplex cylinder compressor to open operation with single cylinder mode of operation；If temperature detection value is less than
The difference A0-C0 of 4th temperature threshold and the 4th difference, then be down to relatively normal state at a temperature of indoor heat exchanger, controls mould
Block 30 can allow duplex cylinder compressor to open operation with twin-tub mode of operation.
That is, as shown in figure 3, when the operational mode of air conditioner becomes for heating mode and temperature detection value in decline
During gesture, the difference B0-D0 of the 3rd temperature threshold and the 3rd difference, which can be used as, judges duplex cylinder compressor with single cylinder mode of operation or twin-tub
Mode of operation opens the critical condition of operation, and the difference A0-C0 of the 4th temperature threshold and the 4th difference can be as determining whether
Open the critical condition of duplex cylinder compressor.When 3rd difference D0 and the 4th difference C0 cause temperature detection value in downward trend
Critical condition when critical condition is in ascendant trend with temperature detection value is slightly changed, and in the condition after change, the 3rd
Temperature threshold and the difference B0-D0 of the 3rd difference are so less than the 4th temperature threshold and the difference A0-C0's of the 4th difference.
It should be noted that the big I of first to fourth above-mentioned temperature threshold, first to fourth difference is according to interior
The temperature of heat exchanger is set to the actual influence of the operation of duplex cylinder compressor.
In addition, in one embodiment of the invention, can also have display on the control panel or remote control of air conditioner
Screen, running status or fault message to show air conditioner etc..For example, when the operational mode of air conditioner is refrigeration mode
And temperature detection value be in downward trend when, if temperature detection value be less than second temperature threshold value B, can be reminded by display screen
The temperature of user's current indoor heat exchanger is too low, is unsatisfactory for opening the condition of duplex cylinder compressor.
