It please refers to Fig.1 and Fig. 2, the air conditioner of embodiment of the present invention includes air handling system and air cleaning system. Air cleaning system includes motor, and air handling system includes compressor, and the control method of air conditioner includes the following steps:
S10:Detect the absolute value of the first temperature gap of indoor temperature and target temperature;
S20:When the absolute value of the first temperature gap is less than or equal to predetermined threshold, outdoor temperature and indoor temperature are detected Second temperature it is poor;With
S30:The frequency of the rotating speed and compressor of motor is controlled according to second temperature difference.
Referring to Fig. 2, the air conditioner 1000 of embodiment of the present invention includes air handling system 100, air cleaning system 200, memory and processor.Air conditioning and cleaning system 200 includes motor 210, and air handling system 100 includes compressor 110, is deposited Reservoir is stored with an at least program, and processor is for executing an at least program.As an example, the air-conditioning of embodiment of the present invention The control method of device can be realized by the air conditioner 1000 of embodiment of the present invention, and can be applied to air conditioner 1000.
Wherein, the step S10 to S30 of the control method of the air conditioner of embodiment of the present invention can be realized by processor. In other words, processor is used to execute program the absolute of the first temperature gap to realize detection indoor temperature and target temperature Value;When the absolute value of the first temperature gap is less than or equal to predetermined threshold, the second temperature of outdoor temperature and indoor temperature is detected Degree is poor;And the frequency of the rotating speed and compressor of motor is controlled according to second temperature difference.
Wherein, memory can be the special of the memory of independent memory air conditioner or dynamically distribute A part.Processor can be the one of the special of the processor of independent processor air conditioner or dynamic allocation Part.
The concern to air quality and demand with people, for example independent air of product with air-cleaning function are net Change device, fresh air system etc. to progress into daily life, typically, however, these air clearing products are detached with air conditioner to be set It sets, when outdoor temperature changes or user has temperature adjustment demand, independent operating, power consumption are higher always for air conditioner.
The air conditioner 1000 of embodiment of the present invention includes air handling system 100 and air cleaning system 200, and air-conditioning 200 integrated setting of regulating system 100 and air cleaning system.Such as cabinet-type air conditioner, air handling system 100 can be located at The top of air cleaning system 200.Certainly, air conditioner 1000 is not limited herein also to be on-hook.Air handling system 100 For freezing or heating comprising there is compressor 110.Air handling system 100 is freezed, and the low-pressure steam of refrigerant is by compressor Simultaneously boil down to high steam heel row to outdoor heat exchanger (not shown), at this time outdoor heat exchanger is condenser for (not shown) sucking, The outdoor air of the aerofoil fan (not shown) sucking of outdoor fan flows through outdoor heat exchanger simultaneously, takes away the heat of refrigerant releasing Amount, makes high pressure refrigerant vapor be condensed into highly pressurised liquid.Highly pressurised liquid is by filter (not shown), throttle mechanism (not shown) Indoor heat exchanger (not shown) is sprayed into afterwards, and indoor heat exchanger is evaporator at this time, and is evaporated under corresponding low pressure, and surrounding is drawn Heat.Indoor fan makes the air to turn cold after heat release pass through air duct to be sent to interior simultaneously.The continuous recycle stream of such room air It is dynamic, achieve the purpose that reduce temperature or dehumidifying.The heating operations of air conditioning system 100 are opposite with process of refrigerastion.Air purification System 200 can be new wind turbine, and new wind turbine includes air inlet, filter screen, wind turbine and motor 210.Air inlet will be outdoor new Fresh air introduces, and processing is filtered to introduced air by filter screen, filter screen may include antibacterial and mouldproof primary filter, Sponge active carbon layer, cellular activated carbon layer and efficient filter.Motor 210 drives wind turbine to send filtered air via air duct Go out.In this way, indoor air can be purified, it is more advantageous to the health of user.
Air handling system 100 works so that indoor temperature gradually to the temperatures approach of setting, is set when indoor temperature is close When constant temperature is spent, in order to continue to adjust temperature, introducing can be passed through according to the second temperature difference of outdoor temperature and indoor temperature Outdoor air meets the needs of adjusting temperature, to reduce the working frequency of compressor 110, it is possible to understand that ground, in refrigerating operaton When, outdoor temperature is generally higher than indoor temperature, therefore, when second temperature difference is smaller, then illustrates, indoor air temperature this When it is also relatively high, still with compressor 110 refrigeration based on, the rotating speed of the motor 210 of air cleaning system 200 can properly increase increasing The working frequency of big air output, compressor 110 can be reduced suitably, further, when second temperature difference is bigger, then be illustrated, Indoor air temperature is relatively low, the frequency of compressor 110 can be reduced with bigger numerical, while promoting motor with bigger numerical 210 rotating speeds meet temperature adjustment demand with outdoor cold, the power consumption of air handling system 100 are reduced, to reduce air conditioner 1000 Power consumption, it is energy saving.
In conclusion the control method and air conditioner 1000 of the air conditioner of embodiment of the present invention, by target temperature with The temperature gap of indoor temperature and the temperature gap of outdoor temperature and indoor temperature adjust the motor of air cleaning system 200 The working frequency of 210 rotating speeds and the compressor of air handling system 200 210 utilizes the introduced room of air cleaning system 200 Outer air meets the regulatory demand of indoor temperature, reduces the power consumption of air handling system 200, energy saving.
