Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention provides a control method of an air conditioner, specifically an operation method of an air conditioner after a fault occurs, which specifically includes the steps of: presetting a plurality of fault operation modes; then according to the use scene or user requirement of the user, one operation mode with fault corresponding to the use scene or user requirement of the user from the multiple operation modes with fault is taken as the operation mode when the fault occurs; when the air conditioner is in failure, the air conditioner switches from the normal operation mode to the preset failure operation mode and operates the air conditioner components which are set by the failure operation mode and need to be forcibly operated. Therefore, when a fault occurs, the air conditioner can be forcibly operated according to the actual needs of a user without being directly shut down, and the situation that the user causes huge loss due to temporary shutdown of the air conditioner or the use experience is reduced due to shutdown of the air conditioner is avoided.
The operation mode with the fault is set through factory parameter setting, and particularly, a plurality of fault modes with the fault are preset when the equipment leaves a factory, so that the equipment can be conveniently and directly selected according to needs, the condition that each equipment needs to be repeatedly set with the factory mode is avoided, and the modification of a program is reduced.
The multiple fault operation modes specifically include: the system comprises a normal working condition running mode A with a fault, a half working condition running mode B with a fault, a partial assembly running mode C and a delay shutdown mode D. The invention at least provides some reference settings, and particularly can set more modes for selection according to the needs of users, which are all within the protection scope of the invention.
When the air conditioner is in fault, the manufacturer parameter is set to be A, namely the operation mode A with the fault normal working condition represents that when the unit is in fault, the air conditioning unit needs to operate according to the original working condition, and the refrigerating capacity output of the unit is output at full speed according to the actual starting logic.
The factory parameter is set to be B, namely the operation mode B with the fault half-working condition, the air conditioning unit is controlled to perform partial refrigeration, namely the indoor fan is normally started, the output of the outdoor fan and the compressor is reduced, and at the moment, the refrigerating capacity of the unit is reduced by half according to the actual starting logic.
The factory parameter is set to be C, namely a partial assembly operation mode C, the outdoor fan and the compressor of the unit are controlled to be closed, the indoor fan is controlled according to actual gears, and the unit has no refrigeration capacity and only ensures air circulation through blowing.
The factory parameter is set to be D, namely the delayed shutdown mode D, when the unit breaks down, the load of the unit needs to be shut down, the compressor of the unit is immediately closed, the indoor fan and the outdoor fan are closed after delaying the compressor for a period of time, and at the moment, the unit does not have any output and is equal to a shutdown state.
In specific practice, the factory parameter of a general unit in a factory is set to be D, a default unit enters shutdown processing when a fault occurs, a load is closed, other options of the factory parameter can be set according to the actual use environment of a user, if the use environment of the user is special, the service life of the unit is not considered, the factory parameter needs to be set to be A, at the moment, even if the unit fails, the refrigeration effect of the unit is ensured to be consistent with the original effect, and the requirement of the user is ensured to be met. If the user is slightly special in the use environment and the requirement on the cooling effect is not so strict, the parameter is set as B, and the unit fails, the cooling capacity of the unit is reduced, but the cooling effect still exists. If the user does not have a requirement on the refrigeration effect, but the air circulation is ensured, the factory parameter of the unit is set to be C, and the inner fan runs at the moment to ensure the blowing function; if the user does not have the requirement on the performance of the unit, the service life of the unit is ensured, the unit is set to be D, and the unit breaks down at the moment and is shut down.
In a specific embodiment, the usage scenario of the user may include: the system comprises a vehicle air conditioner using scene, a ship air conditioner using scene, a machine room air conditioner using scene and a service station air conditioner using scene.
Specifically, for example, when an air conditioner is installed on a vehicle, the vicinity of the vehicle catches fire, the ambient temperature rises, and thus protection or faults occur and the operation is stopped, if the A is set, the faults can be ignored and continue to operate as before, and therefore the safety in the vehicle is guaranteed. When the air conditioner is installed in a machine room for use, the value of equipment in the machine room is often higher than the value of the air conditioner, so that the air conditioner needs to be forcibly operated when a fault occurs, the fault caused by high temperature of the equipment is avoided, and the fault normal working condition operation mode A can be selected when the air conditioner leaves a factory. When the user uses the air conditioner using scene at some service stations, the partial component operation mode C can be selected to ensure the circulation of air because the people flow is large.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
