The invention provides a control method of an air conditioner. The air conditioner comprises two sets of heat exchange systems, namely two sets of compressor systems which are respectively a first heat exchange system and a second heat exchange system. When the air conditioner normally operates, only one of the heat exchange systems is operated, and the heat exchange requirement can be met. When the air conditioner operates, only one set of heat exchange system is operated, and the other set of heat exchange system is used as a standby heat exchange system. And when the running heat exchange system fails to operate, starting the standby heat exchange system, so that the air conditioning unit does not stop to operate. Optionally, the two sets of heat exchange systems share the indoor fan and/or the outdoor fan, so that the equipment cost can be saved, and the equipment volume can be reduced.
Fig. 1 is a method schematic diagram of an embodiment of a control method of an air conditioner provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110, step S120, and step S130.
And step S110, after the air conditioner is started, controlling a first compressor of the first heat exchange system or a second compressor of the second heat exchange system to start.
Specifically, after the air conditioner is started, whether the accumulated operation time of the first compressor of the first heat exchange system is less than or equal to the accumulated operation time of the second compressor of the second heat exchange system is judged. And if the accumulated running time of the first compressor is judged to be less than or equal to the accumulated running time of the second compressor, controlling the first compressor of the first heat exchange system to start. And if the accumulated running time of the first compressor is judged to be greater than that of the second compressor, controlling the second compressor of the second heat exchange system to start.
Specifically, whether the accumulated operation time of the first compressor of the first heat exchange system is less than or equal to the accumulated operation time of the second compressor of the second heat exchange system is judged. And if the accumulated running time of the first compressor is judged to be less than that of the second compressor, controlling the first compressor of the first heat exchange system to start. And if the accumulated running time of the first compressor is equal to the accumulated running time of the second compressor, the first compressor of the first heat exchange system is preferentially controlled to be started. And if the accumulated running time of the first compressor is judged to be greater than that of the second compressor, controlling the second compressor of the second heat exchange system to start.
Preferably, after the air conditioner is started, whether an input signal of a controller of the air conditioner is normal is detected, and after all the input signals of the controller of the air conditioner are detected to be normal and an indoor fan and an outdoor fan are both normally started, a first compressor of the first heat exchange system is controlled to be started or a second compressor of the second heat exchange system is controlled to be started. That is, after the air conditioner is turned on, the unit is started after the controller of the air conditioner detects that all input signals are normal.
Specifically, after the air conditioner is started, whether a temperature detection device of the air conditioner is in fault or not and whether a high-low pressure sensor is in fault or not are detected. The temperature detection means comprise, for example, a bulb and/or a temperature sensor. For example, at least one of an outdoor environment temperature sensing bulb, an indoor return air temperature sensing bulb and an air supply temperature sensing bulb. And if the temperature sensing bulb fails, assigning the temperature sensing bulb to enable the unit to normally operate. For example, when the compressor is a fixed-frequency unit, the value of the thermal bulb can be programmed with the assignment of the corresponding failed thermal bulb by testing various parameters at different ring temperatures in advance.
If one of the two heat exchange systems has a high-pressure fault or a low-pressure fault, the other heat exchange system is started to ensure the normal operation of the unit. The compressor is controlled through the difference between the detected air-conditioning return air temperature and the set temperature, for example, when the compressor is a fixed-frequency compressor, the compressor is controlled to be started and shut down through the difference between the detected air-conditioning return air temperature and the set temperature.
And under the condition that the temperature detection device and the high-low pressure sensor of the air conditioner are detected to be normal, controlling the indoor fan and the outdoor fan to be started, and if the indoor fan and the outdoor fan are both normally started, judging whether the accumulated running time of the first compressor of the first heat exchange system is less than or equal to the accumulated running time of the second compressor of the second heat exchange system, so as to control the first compressor of the first heat exchange system to be started or control the second compressor of the second heat exchange system to be started.
Specifically, when the temperature sensing bulb and the high-low pressure switch are detected to be normal, after a throttle valve (a throttle valve between an indoor heat exchanger and an outdoor heat exchanger, such as an electronic expansion valve) of the air conditioning unit is reset, the valve step number is opened to the set valve step number at the corresponding ambient temperature, then the indoor fan and the outdoor fan are controlled to be started, and if the indoor fan and the outdoor fan are not started normally, problems are timely checked and reported for repair. The electronic expansion valve is reset to the valve step number set by the program after being closed, and then the electronic expansion valve is opened to the valve step number set by the current ring temperature according to the current ring temperature. After the indoor and outdoor fans are normally started, the throttle valve (which is a throttle valve between the indoor heat exchanger and the outdoor heat exchanger, such as an electronic expansion valve) of the air conditioning unit is reset, the valve step number is set to the corresponding ambient temperature, and then the first compressor or the second compressor is controlled to be started according to the judgment.
Step S120, after controlling the first compressor or the second compressor to start, determining whether the first compressor or the second compressor starts normally.
Step S130, if it is determined that the first compressor is not normally started, controlling the second compressor to start, or, if it is determined that the second compressor is not normally started, controlling the first compressor to start.
Specifically, under the condition that the accumulated running time of the first compressor is judged to be less than or equal to the accumulated running time of the second compressor, and the first compressor of the first heat exchange system is controlled to start, after the first compressor is controlled to start, whether the first compressor is normally started is judged, and if the first compressor is judged not to be normally started, the second compressor is controlled to start; and under the condition that the accumulated running time of the first compressor is judged to be greater than that of the second compressor, and the second compressor of the second heat exchange system is controlled to start, judging whether the second compressor is normally started or not after the second compressor is controlled to start, and controlling the first compressor to start if the second compressor is judged not to be normally started.
Further, based on the above embodiment, after controlling the first compressor to start, under the condition that it is determined that the first compressor is not normally started, after controlling the second compressor to start, if it is determined that the second compressor is normally started, sending a notification message that the first heat exchange system has a fault, for example, displaying a fault code; and if the second compressor is judged not to be normally started, controlling the air conditioner to stop so as to carry out fault maintenance. After controlling the second compressor to start, under the condition that the second compressor is judged not to be normally started, after controlling the first compressor to start, if the first compressor is judged to be normally started, sending out a prompt message that the second heat exchange system has a fault, such as displaying a fault code; and if the first compressor is judged not to be normally started, controlling the air conditioner to stop so as to carry out fault maintenance.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the control method of the air conditioner provided by the present invention with a specific embodiment.
Fig. 2 is a schematic method diagram of an embodiment of a method for controlling an air conditioner according to the present invention. As shown in fig. 2, when the unit is in a cooling operation, the controller detects that all input signals are normal, and then the unit can be started. The unit automatically controls the start and the stop of a compressor through the difference between the detected air-conditioning return air temperature and the set temperature, the starting detects whether a temperature sensing bulb and a high-low pressure sensor of a first heat exchange system (a system 1 in the figure) and a first heat exchange system (a system 2 in the figure) have faults or not, if the temperature sensing bulb has the faults, the temperature sensing bulb is assigned to enable the unit to normally operate, and meanwhile, a fault code of the corresponding temperature sensing bulb is reported, if one system has the faults, the other system is started to ensure the unit to normally operate, and meanwhile, a corresponding fault code is reported; when the temperature sensing bulb and the high-low pressure detection are normal, the electronic expansion valve is reset, the valve step number is started to the set valve step number at the corresponding environment temperature, then the indoor fan and the outdoor fan are started, if the indoor fan and the outdoor fan are not started normally, the problem is checked in time, and the problem is reported and repaired; after the indoor and outdoor fans are normally started, the electronic expansion valve of the unit is reset, and the valve steps are opened to the set valve steps at the corresponding ambient temperature.
Starting a compressor, if the accumulated running time of a first compressor (compressor 1) of a first heat exchange system is less than or equal to the accumulated running time of a second compressor (compressor 2) of a second heat exchange system, starting the first compressor (compressor 1) of the first heat exchange system, judging whether the first compressor runs normally, if the first compressor fails, starting the second compressor (compressor 2) of the second heat exchange system, and judging whether the second compressor runs normally; if the second compressor starts normally, the unit continues to operate, meanwhile, the fault of the first heat exchange system is reported, so that the maintenance can be carried out in time, and if the second compressor does not start normally, the machine is stopped for maintenance. If the accumulated running time of a first compressor (compressor 1) of the first heat exchange system is greater than the accumulated running time of a second compressor (compressor 2) of the second heat exchange system, starting the second compressor (compressor 2) of the second heat exchange system, judging whether the second compressor is normally started, if the second compressor is failed, starting the first compressor (compressor 1) of the first heat exchange system, and judging whether the first compressor is normally started; if the first compressor is started normally, the unit continues to operate, meanwhile, the second heat exchange system fault is reported so as to be convenient to overhaul in time, and if the second compressor is not started normally, the unit is shut down to overhaul. Sufficient time is provided for maintenance, the use of the client is not delayed, and the maintenance personnel can be fully prepared.
The invention also provides a control device of the air conditioner. The air conditioner comprises two sets of heat exchange systems, namely two sets of compressor systems which are respectively a first heat exchange system and a second heat exchange system. When the air conditioner normally operates, only one of the heat exchange systems is operated, and the heat exchange requirement can be met. When the air conditioner operates, only one set of heat exchange system is operated, and the other set of heat exchange system is used as a standby heat exchange system. And when the running heat exchange system fails to operate, starting the standby heat exchange system, so that the air conditioning unit does not stop to operate. Optionally, the two sets of heat exchange systems share the indoor fan and/or the outdoor fan, so that the equipment cost can be saved, and the equipment volume can be reduced.

If the accumulated operation time of the first compressor is determined to be less than the accumulated operation time of the second compressor, the control unit 110 controls the first compressor of the first heat exchange system to start. The default starting priority of the first heat exchange system is higher, and if the accumulated running time of the first compressor is determined to be equal to the accumulated running time of the second compressor, the control unit 110 preferentially controls the first compressor of the first heat exchange system to start.

The temperature detection means comprise, for example, a bulb and/or a temperature sensor. For example, at least one of an outdoor environment temperature sensing bulb, an indoor return air temperature sensing bulb and an air supply temperature sensing bulb. And if the temperature sensing bulb fails, assigning the temperature sensing bulb to enable the unit to normally operate. For example, when the compressor is a fixed-frequency unit, the value of the thermal bulb can be programmed with the assignment of the corresponding failed thermal bulb by testing various parameters at different ring temperatures in advance.
