According to fig. 1, the present embodiment provides a control method for detecting a closed space, which is applied to an air conditioning unit, and includes the following steps:
calculating the maximum time required by the air conditioning unit to normally run to each windshield and reach a set temperature threshold value under different areas, different outer ring temperatures and different inner ring temperature intervals;
the maximum time calculation operation is performed in the air conditioner development stage, and developers perform maximum time calculation on the developed air conditioner, for example, the maximum time required for the developed air conditioner to normally run to each windshield and reach a set temperature threshold under the sections with different areas, different outer ring temperatures and different inner ring temperature intervals shown in the following table 1:
TABLE 1
And (4) supplementary notes: table 1 only lists the maximum time values under some parameters, and the maximum time values under different parameters need to be measured and calculated specifically.
The maximum time value required for the air conditioner unit to normally run to each windshield and reach the set temperature threshold value under different areas, different outer ring temperatures and different inner ring temperature intervals calculated in the development stage is stored in an operation system storage device of the air conditioner unit or stored in a cloud server of a service provider, and the maximum time parameter is obtained through wireless transmission means such as WIFI during each use.
When the maximum time is calculated in the development stage, the maximum time can be calculated under the conditions that the system can reach the minimum fluorine state with a set temperature threshold value, two devices of the system run under certain blockage conditions, the indoor and outdoor air can be in an acceptable heat exchange range (such as through space heat exchange such as a door gap), and the like, so that the maximum time value is obtained and better accords with the state of the air conditioning unit in actual running, and the control of detecting a closed space is more accurate.
When the air conditioning unit normally operates, judging the difference value between the current inner ring temperature and the set temperature, and judging whether to enter timing operation or not according to the difference value;
if the timing operation is started, judging the difference value between the current timing variable and the calculated maximum time, and judging whether the air conditioning unit has an abnormal state according to the difference value;
and when the air conditioning unit is in an abnormal state, sending out reminding information and clearing the timing variable.
The mode of reminding the user can be sent to the user terminal through an internal machine display panel or a wireless transmission means, the user controls the air conditioner to react and can be controlled through a remote controller or a mobile terminal APP, if the air conditioner has a wireless transmission function, the data such as the current ambient temperature, the running pipe temperature, the time probably needed when the current ambient temperature reaches a set temperature point and the like can be selectively displayed on the user terminal, and the user can know the running state of the current air conditioning unit.
When a user uses the current function, the size of the current room needs to be set firstly, the current room can be set through a remote controller or a mobile phone APP through WIFI, the setting is only needed once, the subsequent modification is carried out, the specific input is subject to the final setting, and if the current function is not set, a default room size is provided or the user is forcibly reminded that the current function cannot be used if the current function needs to be set; when the user receives the prompt, after the user knows that the heat exchange is not the prompt of the closed environment, the user can control the current air conditioner to continue to operate through a remote controller or a mobile phone APP, and the selectable modes include but are not limited to modes of increasing the frequency of the compressor, appropriately releasing some limit points, stopping the air conditioner for a period of time (which can be artificially set for a certain time), or keeping the air conditioner from doing any treatment and the like.
The air conditioner has an abnormal state, and then indicates that the current indoor environment and the outdoor environment have a large amount of heat exchange, and through reminding the user this condition, can avoid the human factor to cause user experience poor to can make the user clearly know the running state of current air conditioning unit, can also avoid the waste of the energy on the basis of strengthening user experience, can control the energy consumption problem of air conditioner operation in-process.
