Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of indoor fan control method, with reference to Fig. 1, in indoor fan control method first embodiment of the present invention, this indoor fan control method comprises:
Step S10, the critical temperature value of state change occurs when obtaining indoor-unit cooling-medium heat exchange, and described critical temperature value comprises evaporating temperature and condensation temperature;
The indoor fan control method that the embodiment of the present invention provides is mainly used in air-conditioning system, for controlling indoor fan, this air-conditioning system can, for only comprising the Air Conditioning System of an indoor set, also can be the multi-online air-conditioning system comprising multiple indoor set.In multiple on-line system, each indoor set all can independently control, and indoor fan rotating speed also independently can be controlled by each indoor set voluntarily.
Particularly, when air-conditioning heating runs, the critical temperature value that state change occurs when obtaining indoor-unit cooling-medium heat exchange is the condensation temperature (temperature value of critical point when refrigerant is changed to liquid state from steam state in indoor set) of refrigerant; When air conditioner refrigerating runs, the critical temperature value that state change occurs when obtaining indoor-unit cooling-medium heat exchange is the evaporating temperature (temperature value of critical point when refrigerant is changed to steam state from liquid state in indoor set) of refrigerant.
The obtain manner of above-mentioned condensation temperature and evaporating temperature can be arranged according to actual needs, such as can by coiler temperature or pressure in sensing chamber, according to detecting that the temperature of indoor set coil pipe predetermined position equals critical temperature value substantially, or calculate according to the pressure of refrigerant.
Step S20, judges whether described critical temperature value is positioned at preset error scope corresponding to preset temperature; If so, terminate; If not, then step S30 is performed;
Step S30, when described critical temperature value is greater than the maximum of described preset error scope, reduces the rotating speed of described indoor set; When described critical temperature value is less than the minimum of a value of described preset error scope, promote the rotating speed of described indoor set.
Above-mentioned preset temperature sets the target temperature value Ts that operation of air conditioner reaches for user, and the preset error scope that this target temperature value Ts is corresponding can be [Ts-a, Ts+b], then the minimum of a value of above-mentioned preset error scope is Ts-a, and maximum is Ts+b.When getting above-mentioned critical temperature value Te, can adjust according to the rotating speed of relation to indoor fan of preset error scope and preset error scope.
When operation of air conditioner, if Ts-a≤Te≤Ts+b, then determine that described critical temperature value is positioned at the preset error scope of preset temperature, now will the wind speed of indoor set not adjusted; As Te < Ts-a, then promote the rotating speed of indoor fan; As Te > Ts+b, then reduce the rotating speed of indoor fan.
The critical temperature value of state change occurs time in the embodiment of the present invention by obtaining indoor-unit cooling-medium heat exchange, and described critical temperature value comprises evaporating temperature and condensation temperature; Judge whether described critical temperature value is positioned at preset error scope corresponding to preset temperature; When described critical temperature value is greater than the maximum of described preset error scope, reduce the rotating speed of described indoor set; When described critical temperature value is less than the minimum of a value of described preset error scope, promote the rotating speed of described indoor set.Due to indoor fan control method provided by the invention achieve in indoor set, carry out heat exchange according to refrigerant time corresponding evaporating temperature and condensation temperature automatically to the adjustment of rotational speed of indoor fan, thus reduce the loss of electric energy, prevent waste of energy.
Further, with reference to Fig. 2, based on indoor fan control method first embodiment of the present invention, in indoor fan control method second embodiment of the present invention, also comprise after above-mentioned steps S30:
Step S40, judges whether the duration that described indoor fan runs according to the rotating speed after adjustment is greater than preset value;
In the present embodiment, adjustment described indoor fan rotating speed after, indoor fan by according to adjustment after rotating speed continuous service.In the process run, the duration whether above-mentioned preset value that real-time judge indoor fan runs according to the rotating speed after adjustment, when the duration is greater than preset value, the critical-temperature Value Operations of state change will be there is when again performing and obtain indoor-unit cooling-medium heat exchange, to enter adjustment next time, until the absolute value of the difference of above-mentioned critical temperature value and preset temperature is positioned at pre-set interval, thus indoor fan is made to reach preferably rotating speed.
