The temperature for ringing the indoor unit effectively reduces defrost bring difference variation, improves user's comfort, so that indoor unit institute is right
The experience of the indoor user answered is more preferable.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes part of this application, this hair
Bright illustrative embodiments and their description are used to explain the present invention, and are not constituted improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is air-conditioning defrosting method flow chart provided in an embodiment of the present invention.
Specific embodiment
Technical solution provided by the invention is illustrated in more detail below with reference to Fig. 1.
The present invention provides a kind of air-conditioning defrosting method, comprising the following steps: in control room in the indoor unit of someone at least
One is not involved in defrost.
The in running order indoor unit ratio of indoor nobody (or being indoor no user) is if any multiple, above-mentioned air-conditioning
White method controls at least one of these indoor units and is not involved in defrost.It is so-called to be not involved in defrost and refer to, it is not flowed in the indoor unit
Enter refrigerant, is not involved in the circulation of defrost.The mode of specific implementation is such as are as follows: the electronics controlled on the refrigerant channel of the indoor unit is swollen
The aperture of swollen valve flows into the indoor unit without refrigerant, therefore it is not involved in defrost and follows if electric expansion valve is in close state
Ring.
The air-conditioning defrosting method that above-mentioned technical proposal provides, under booting heating state, all has personnel movable
Room indoor unit or part indoor unit are not involved in defrost, and fluctuations in indoor temperature caused by reducing because of defrost improves user
Comfort.
In some embodiments, it includes following step that at least one of the indoor unit of someone, which is not involved in defrost, in control room
Rapid: the rated capacity summation of the indoor unit of the indoor someone of monitoring accounts for the ratio X of the specified total capacity summation of the interior machine of all working.
In this step, X is real-time monitoring amount, and range is between 0 to 1.
If X≤N, the indoor unit of all interior someone is not involved in defrost.Wherein N is setting value.In this step, according to
Comparison result judge air-conditioning how defrost.
In some embodiments, air-conditioning defrosting method is further comprising the steps of: if X > N, controlling preferential indoor unit and does not join
With defrost, wherein N is the ratio of the rated capacity summation of preset preferential indoor unit and the rated capacity summation of all indoor units
Example.
In this step, N can be set when leaving the factory, be set when perhaps being set as being used for the first time by user or every
It is set before secondary defrost.
Preferential indoor unit (or being VIP indoor unit), there are many modes that preferential indoor unit is arranged, such as by key customer
Indoor unit corresponding to the room used is set as VIP indoor unit.Key customer is such as old man, child, business district user etc..
In some embodiments, N meets the following conditions: N≤1-M.Wherein, M is minimum needed for preset air-conditioning defrost
The ratio of rated capacity.
In some embodiments, N is between 0 to 50%.It is specifically such as 0,10%, 20%, 30%, 40%, 50%.
In some embodiments, M 30%-60% is specifically such as 30%, 40%, 50%, 55%, 60%.
It controls, the intelligent object and big data point carried by unit
Whether analysis, monitoring interior have personnel activity, or whether interior is chronically at unmanned state, by logic control, there is interior
All or part of indoor unit of people is not involved in defrost, to improve user's comfort.
In some embodiments, using infrared sensor detection it is indoor whether someone.After detecting indoor someone, according to
Whether subsequent control operation, the indoor unit for controlling interior someone participate in defrost.
In some embodiments, be not involved in defrost using following step control indoor unit: closing connect cold with indoor unit
Control valve in matchmaker's pipeline.
After control valve is closed, refrigerant can not flow into indoor unit, which is not involved in the refrigerant circulation of air-conditioning system, therefore
It is not involved in defrost.
In some embodiments, control valve includes electric expansion valve.Electric expansion valve is easy to implement automation control.
A specific embodiment is introduced below with reference to Fig. 1.After unit regulation, following step is carried out:
Step S100, by the intellectual monitoring module and big data analysis on air conditioner, whether monitoring interior has personnel living
It is dynamic.
Step S200, there is accounting for for the indoor unit of user relatively all specified total capacities of indoor unit of specified total capacity in Data Analyzing Room
Compare X.
Step S300, minimum rated capacity accounting M required for air conditioner defrost is set.
Step S400, as X≤(1-M), the indoor unit of all interior someone is without participation defrost.
Step S500, as X > (1-M), all interior machines can be allowed to be involved in defrost.Also it is useful to can choose part interior
The indoor unit at family is not involved in defrost.
It can be applied to many situations herein, a certain number of VIP users can be set, the specified total capacity of machine in VIP
For N, wherein meeting N≤(1-M).No matter X is much, as long as there are machine all needing not participate in personnel's recreation room in VIP user interior
Frost greatlys improve the user experience of VIP user.
Specifically such as by control indoor unit electric expansion valve whether have aperture, control the indoor unit whether participation
Which unit frost can control participate in defrost that is, by the opening degree of the electric expansion valve of all interior machines of logic control.
The embodiment of the present invention also provides a kind of air-conditioning, including controller, and controller is configured as according to the interior detected
Have whether nobody information control indoor unit participates in defrost.
In some embodiments, air-conditioning further includes detector, detector be configurable for detection it is indoor whether someone；Institute
Detector is stated to be electrically connected with the controller.
Detector is such as the included intellectual monitoring control system of unit or is infrared sensor.
