Based on the hardware structures of the operation control device 100 and the mobile air conditioner, various embodiments of the air conditioner detection method of the present invention are proposed.
Referring to fig. 8, fig. 8 is a flowchart of an air conditioner detection method according to an embodiment of the present invention, the air conditioner detection method is applied to a mobile air conditioner, wherein the mobile air conditioner includes an outdoor heat exchange air duct for communicating with an outdoor environment, and the air conditioner detection method includes, but is not limited to, step S100, step S200, and step S300.
Step S100: under the condition that the mobile air conditioner executes air conditioning for a first time period, acquiring a first indoor environment temperature value and a first outdoor environment temperature value, wherein the first outdoor environment temperature value is the temperature value of outdoor environment air corresponding to the air inlet side of the outdoor heat exchange air duct;

In an embodiment, the embodiment of the invention can obtain a first indoor environment temperature value and a first outdoor environment temperature value, and when the first indoor environment temperature value meets a first condition, the first outdoor environment temperature value meets a second condition, and the protection shutdown frequency of the mobile air conditioner reaches a preset frequency within a preset time period, the embodiment of the invention can effectively detect that the mobile air conditioner is in a heat exchange abnormal state, and can perform corresponding protection processing, thereby ensuring the normal operation of the mobile air conditioner.
It should be noted that, in the existing scheme, only the situation that one of the indoor heat exchange structure or the outdoor heat exchange structure is blocked is considered, the system can still exchange heat, and the load does not have the extreme situation that the indoor heat exchange structure and the outdoor heat exchange structure are completely blocked.
It is noted that the first condition is that the first indoor environment temperature value is greater than a first preset temperature value, the first indoor environment temperature value is greater than a second indoor environment temperature value, and a difference value between the first indoor environment temperature value and the second indoor environment temperature value is greater than a first preset threshold value, the second indoor environment temperature value is a temperature value detected before the mobile air conditioner performs air conditioning; the second condition is that the first outdoor environment temperature value is greater than a second preset temperature value, and an absolute value of a difference between the first indoor environment temperature value and the first outdoor environment temperature value is less than a second preset threshold value.
It can be understood that, regarding the first preset temperature value, the first preset threshold value, the second preset temperature value, the second preset threshold value and the preset times, the setting may be manually input after the experimental test result is obtained. For example, the first preset temperature value may be set to fifty degrees celsius, the first preset threshold value may be set to five degrees celsius, the second preset temperature value may be set to fifty degrees celsius, the second preset threshold value may be set to two degrees celsius, and the preset number of times may be set to three.
Secondly, it is worth noting that regarding the first indoor environment temperature value and the second indoor environment temperature value in the above steps, the first indoor environment temperature value and the second indoor environment temperature value are both the temperature values of the indoor environment air corresponding to the air inlet side of the indoor heat exchange air duct. In order to make the detection result more accurate and reliable, in particular, in the embodiment of the present invention, the air temperature value of the first air inlet may be selected and collected as the first indoor environment temperature value and the second indoor environment temperature value. Specifically, under the action of the air draft of the first fan, the air in the indoor environment sequentially passes through the first air inlet, the evaporator and the first fan and is finally discharged to the indoor space from the first air outlet. It can be understood that, in order to be able to acquire the first indoor environment temperature value and the second indoor environment temperature value, the embodiment of the present invention may be provided with a temperature sensor at the position of the first air inlet.
In addition, it is noted that, regarding the first outdoor environment temperature value in the above steps, the first outdoor environment temperature value is a temperature value of outdoor environment air corresponding to the air inlet side of the outdoor heat exchange air duct. In order to make the detection result more accurate and reliable, in particular, the embodiment of the invention may select and collect the air temperature value of the second air inlet as the first outdoor environment temperature value. Specifically, under the action of the air draft of the second fan, the air in the outdoor environment sequentially passes through the air inlet pipe, the second air inlet, the condenser and the second fan and is finally exhausted to the outdoor from the second air outlet and the exhaust pipe. It is understood that, in order to be able to acquire the first outdoor environment temperature value, the embodiment of the present invention may be provided with a temperature sensor at the second air inlet.
It is to be understood that, regarding the preset time period described above, it may be a time period after the mobile air conditioner performs air conditioning for a first time period. Secondly, the first time period and the preset time period can be set by manual input according to the experimental test result. For example, the first time period may be set to twenty minutes, and the preset time period may be set to fifteen minutes.
In addition, as for the air conditioning performed in the above steps, it may include, but is not limited to, performing a cooling conditioning or performing a dehumidifying conditioning. Wherein, can understand that, the air conditioner function of dehumidifying contains the refrigeration effect, and the air conditioner dehumidification means that whole air conditioner is in dehumidification running state, and the fan of first fan operates very slowly this moment, and the purpose is for the aqueous vapor condensation in the convenience air becomes liquid and reaches the effect of dehumidification.
In addition, it is understood that the protection shutdown times in the above steps include, but are not limited to, the shutdown times caused by the temperature value of the condenser exceeding the first threshold temperature value or the shutdown times caused by the discharge temperature value of the compressor exceeding the second threshold temperature value.
Specifically, as shown in fig. 9, fig. 9 is a logic diagram of the condenser over-temperature protection provided by one embodiment of the present invention. When the temperature of the condenser rises and is higher than a first threshold temperature value TC1, the mobile air conditioner enters a shutdown protection state, the compressor responds to shutdown, and one-time protection shutdown is recorded; then, when the temperature of the condenser drops to be lower than a third threshold temperature value TC2, the mobile air conditioner enters an operation state, and the compressor is allowed to be started.
Additionally, as shown in FIG. 10, FIG. 10 is a logical relationship diagram of the compressor discharge over-temperature protection provided by one embodiment of the present invention. When the exhaust temperature of the compressor rises and is higher than a second threshold temperature value TP1, the mobile air conditioner enters a shutdown protection state, the compressor responds to shutdown, and a one-time protection shutdown is recorded; then, when the discharge temperature of the compressor drops below the fourth threshold temperature value TP2, the mobile air conditioner enters the operation state, and the compressor is allowed to be started.
It should be noted that the state of the mobile air conditioner before performing air conditioning may refer to that the mobile air conditioner is in a power-on state and before starting the cooling module or the dehumidification mode, the mobile air conditioner can normally acquire the second indoor environment temperature value because the mobile air conditioner is in the power-on state.
Referring to fig. 11, fig. 11 is a flowchart of an air conditioner detection method according to another embodiment of the present invention, and regarding step S300, there are, but not limited to, step S510 and step S520.
