Accompanying drawing explanation
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes of the application
Point, the schematic description and description of the present invention is used for explaining the present invention, is not intended that the present invention's
Improper restriction.In the accompanying drawings:
Fig. 1 is the flow chart of the off-premises station defrosting control method of first embodiment of the invention；
Fig. 2 is the flow chart of the off-premises station defrosting control method of second embodiment of the invention；
Fig. 3 is the structure principle chart of the off-premises station defrosting control device of the embodiment of the present invention.
Detailed description of the invention
In the following detailed description, a large amount of specific detail is proposed, in order to provide the thorough reason to the present invention
Solve.However it will be understood by those of ordinary skill in the art that, even if not having these specific detail can implement this yet
Bright.In other cases, it is not described in well-known method, process, assembly and circuit, with
Exempt to affect the understanding of the present invention.
In conjunction with seeing shown in Fig. 1 and Fig. 2, according to embodiments of the invention, off-premises station defrosting control method
Including: whether detection air-conditioning enters defrosting mode；When detecting that air-conditioning enters defrosting mode, sensing chamber
Whether room, interior machine place has people；According to testing result, the blower fan that indoor set is corresponding is controlled.
Whether people is had by detection room, indoor set place, can be according to testing result to corresponding to indoor set
Blower fan be adjusted, on the basis of not affecting human sense of comfort, suitably increase the air stream of indoor set
Speed, the heat exchanger effectiveness of indoor set when improving defrosting, shortens the defrosting time of off-premises station.
In conjunction with shown in Figure 1, in an embodiment of the present invention, according to testing result to indoor set
The step that corresponding blower fan is controlled includes: when detecting that there is people in room, indoor set place, and controlling should
The blower fan that the indoor set in room is corresponding stops；When indoor set place room no man being detected, control this room
Between fan operation corresponding to indoor set.When detecting that there is people in room, indoor set place, need to keep being somebody's turn to do
Air themperature in room, it is therefore desirable to controlling the blower fan stopping that the indoor set in this room is corresponding, reducing should
Air velocity in room, reduces the heat exchanger effectiveness of this indoor set and room air, it is to avoid off-premises station enters
Indoor temperature is affected greatly and reduces Consumer's Experience during row defrosting.When room, indoor set place being detected
Between nobody time because without the air themperature keeping this room, therefore can keep fan operation, accelerate
The heat exchanger effectiveness of indoor set in this room, accelerates the defrosting efficiency of off-premises station, thus more fully sharp
With the heat in unmanned room, supplementing the heat needed for off-premises station defrosting, extra heat makes off-premises station defrost
Time shortens, and can accelerate indoor set and recover the speed of heating capacity.
Off-premises station defrosting control method also includes: after detecting that defrosting mode terminates, and controls each indoor set
Run according to the state before defrosting.After off-premises station completes defrosting, indoor set can be controlled according to before
Be set for so that each room returns to the temperature making human body feel comfortably cool, and improves airconditioning control
Intelligent.
Indoor set can be one, it is also possible to for multiple.In the present embodiment, off-premises station is one, room
Interior machine is multiple, and multiple off-premises stations are all connected with indoor set, and each indoor set independently controls, and is formed multi-joint
Air conditioner, according to its indoor, place, whether someone controls each indoor set accordingly.
Whether detection room, indoor set place has the step of people to include: send sense to the room at indoor set place
Induction signal；Testing result is sent to the controller to indoor set.Specifically, people's health check-up can be passed through
Measurement equipment carries out whether room has the detection of people, and to its room, place, whether someone is carried out human body detecting device
After detection, testing result is sent the controller to indoor set, makes controller according to testing result to room
The blower fan of interior machine controls accordingly.Human body detecting device can be infrared induction equipment or other can
To detect whether the equipment of people.After human body detecting device detection room, can be by wired or nothing
The mode of line carries out the transmission of signal, such as by wire transfer, or be transmitted by WIFI etc..
In conjunction with shown in Figure 2, in another embodiment of the invention, according to testing result to indoor set
The step that corresponding blower fan is controlled includes: when detecting that there is people in room, indoor set place, obtains people
The state parameter of body；When the state parameter of human body is below pre-set parameter, control the indoor in this room
The blower fan that machine is corresponding stops；When human body state parameter pre-set parameter and above time, control this room
Rotation speed of fan corresponding to indoor set be reduced to below speed setting value.
In the present embodiment, when detecting that there is people indoor, it is not directly by blower fan corresponding for indoor set
Close down, but according to the parameter of indoor human body, fan operation situation is adjusted, when indoor being detected
When the state parameter of human body is below pre-set parameter, being not in good state of indoor human body is described, may be old
People or child, the blower fan now needing the indoor set controlling in room corresponding stops, and prevents from causing human body
Uncomfortable.When detect the state parameter of human body pre-set parameter and above time, the shape of indoor human body is described
State is preferable, and the rotation speed of fan that can control the indoor set in this room corresponding is reduced to below speed setting value,
On the basis of avoiding indoor human body to cause bigger discomfort so that blower fan can be slightly increased this indoor set with
The air heat exchange efficiency of indoor set, improves the defrosting efficiency of off-premises station.
In conjunction with shown in Figure 3, according to embodiments of the invention, off-premises station defrosting controls device and includes:
Running state detecting device, for detecting the running status of off-premises station；Human body detection device, is used for detecting
Whether room, indoor set place has people；Controller, is respectively connecting to running state detecting device and people's health check-up
Survey device, and corresponding to indoor set with the testing result of human body detection device according to running state detecting device
Blower fan be controlled.Human body detection device is connected with indoor set controller, when detecting by holding wire
During human activity signal, transmission pulse signal, to indoor set controller, makes indoor set controller control this room
Between fan operation state corresponding to indoor set.
Off-premises station defrosting controls device and also includes body state acquisition device, and body state acquisition device connects
To controller, for obtaining body state parameter when human body detection device has detected people.
Human body detection device includes at least one pyroelectric infrared sensor.
The explanation of above example is only intended to help to understand method and the core concept thereof of the present invention；Meanwhile,
For one of ordinary skill in the art, according to the thought of the present invention, at detailed description of the invention and application model
Placing and all will change, in sum, this specification content should not be construed as limitation of the present invention.
