The predetermined humidity range may be 75% to 95%.
In some embodiments, the environment conditioning apparatus 110 may further include a temperature conditioning device 114 for conditioning an ambient temperature of the indoor environment.
The processor 130 may be configured to, after acquiring the control instruction for performing ozone sterilization on the indoor environment, perform temperature adjustment on the indoor environment according to a preset temperature by using the temperature adjustment device 114 in the environment adjustment apparatus 110, so as to quickly increase the relative humidity of the indoor environment, thereby improving the sterilization efficiency and shortening the sterilization time. The predetermined temperature may be 20 to 25 deg.C, such as 20 deg.C, 22 deg.C, 24 deg.C or 25 deg.C. The temperature adjustment of the indoor environment by the temperature adjustment device 114 may be performed prior to the activation of the humidifier 112 or may be performed simultaneously with the activation of the humidifier 112.
In some embodiments, the environmental conditioning apparatus 110 may further include an airflow disruption device 113 for circulating air through the indoor environment to facilitate indoor air flow.
When the humidity of the indoor environment is greater than or equal to the preset first humidity, that is, when the ozone generator 111 is started, the processor 130 may be configured to promote the air flow in the indoor environment by using the airflow disturbance device 113, so that the ozone fills the entire indoor environment, and the sterilization is more sufficient and thorough.

In the present invention, the periodic sterilization may be a single sterilization performed at a predetermined time point, or may be a periodic sterilization performed a plurality of times.
The environmental conditioning system 100 may also include at least one user terminal 120 to remotely send instructions to the processor 130. In the present invention, at least one is one, two, or more than two. That is, the climate regulating device 110 may be in data signal connection with one or more user terminals 120 via the processor 130.
In some embodiments, in which the periodic degerming instruction is received, the processor 130 may be configured to provide a prompt for degerming the indoor environment to at least one user terminal 120, and degerming the indoor environment when an acknowledgement instruction of any user terminal 120 responding to the prompt is received, so as to avoid a situation that the user returns or stays in the indoor environment during degerming due to not seeing the prompt, and reduce a potential safety hazard.

For example, the time information may be to start sterilizing the indoor environment three pm every friday, and the execution time may be two and a half pm every friday.
In some embodiments, in which the immediate sterilization instruction is received, the processor 130 may be configured to receive the immediate sterilization instruction sent by any one of the user terminals 120, record the sending time of the immediate sterilization instruction and the sending times corresponding to the sending time, and display the sending time with the largest sending times to the user when acquiring the time information for performing sterilization on the indoor environment regularly set by the user, so as to facilitate the user operation.
In some further embodiments, the processor 130 may be configured to send an alert message to each user terminal 120 after receiving a confirmation instruction in response to the reminder information or after receiving an immediate sterilization instruction. The reminder message may include at least one of a safety reminder, a time required for the sterilization, and a progress of the sterilization to avoid the user returning or staying in the indoor environment during the sterilization process.
In some further embodiments, after receiving the confirmation instruction in response to the prompt or after receiving the immediate sterilization instruction, the processor 130 may be configured to detect whether the indoor environment is someone or determine whether any one of the users is returning to the indoor environment on the way, and continue until the sterilization is finished, so as to prevent the user from returning to the indoor environment during the sterilization process due to ignoring the safety prompt or not knowing the progress of the sterilization.
Specifically, before the indoor environment is humidified by the humidifier 112 in the environment adjusting apparatus 110, i.e., before the sterilization procedure is started, the processor 130 may be configured to start humidifying the indoor environment by the humidifier 112 in the environment adjusting apparatus 110 when it is detected that the indoor environment is not.

The processor 130 may be configured to track current tracking information of a corresponding user by using a positioning system of the user terminal 120, and determine whether a destination indicated by the current tracking information (i.e., a destination of the user) is an indoor environment according to the current tracking information. And if the destination indicated by the current trace information of any user is judged to be the indoor environment, stopping sterilizing the indoor environment.
The processor 130 may be configured to acquire at least one historical trace information related to the indoor environment of the corresponding user by using the positioning system of the user terminal 120, determine, for each user terminal 120, a trace overlap degree between the current trace information and the at least one historical trace information, and determine, according to the trace overlap degree, whether a destination indicated by the current trace information is an indoor environment, so as to improve accuracy of determining whether the destination indicated by the current trace information is an indoor environment. And if the track coincidence degree of the current track information and any historical track information is greater than or equal to a preset coincidence threshold value, judging that the destination indicated by the current track information is an indoor environment.
Processor 130 may determine a course of action and a time of action from the current whereabouts information and the at least one historical whereabouts information, respectively. The track contact degree can be calculated according to the route contact degree of the current track information and at least one historical track information on the running route and the time contact degree on the action time according to the preset balance weight. For the current track information, the action route can be a route from an origin to the current position, and the action time can be a time period from the departure time to the current time; for the historical track information, the action route may be a route from an origin to a destination, and the action time may be a time period from a departure time to an arrival time.
The counter weight of the route coincidence degree can be larger than the counter weight of the time coincidence degree, so that the accuracy of judging whether the destination of the current track information is an indoor environment is further improved. For example, a route overlap weight is 70% and a time overlap weight is 30%; the route overlap ratio was found to be 60% and the time overlap ratio was found to be 40%.
In the case where the user terminal 120 is running navigation software for route navigation, the processor 130 may also be configured to directly read the destination of the navigation route, and determine whether the user is on the way to return to the indoor environment by determining whether the destination is address information of the indoor environment.
