Specific embodiment
Hereinafter, a specific embodiment of the invention is further described in conjunction with attached drawing.
With reference to Fig. 1 and Fig. 2, a kind of air conditioner, including water pump 1, the reservoir 3 of threshold value and pre-set programs is stored, and
Actuator 2, the pre-set programs can be realized following steps when being executed by the actuator 2: detect current operating status and meter
The yield of condensed water under the operating status is calculated, if the yield of condensed water is greater than threshold value, starts the water pump 1.
Air conditioner of the present invention, by the detection to operating status, and the calculating to condensed water yield, cold
Condensate yield, which reaches, restarts water pump when needing to be discharged, reduce unnecessary power input when detection, when reducing use
Unnecessary power dissipation.
The water pump 1 for being discharged condensed water, the air conditioner further include detection components 4, frequency converter 5, indoor coil 6,
Outdoor coil pipe used 7, indoor fan 8 and outdoor fan 9, the detection components 4 are used to detect the running frequency of the frequency converter 5, room

Degree and outside humidity, detection components 4 described herein preferably comprise frequency detecting unit, multiple temperature sensors and humidity and pass
Sensor, so as to effectively detect each operating parameter and environmental parameter, the operating status includes operational mode, operation ginseng
Several and environmental parameter.
Pre-set programs, threshold value and preset time t s are stored in the reservoir 3, as shown in Fig. 2, the pre-set programs packet
Include following steps:
Firstly, the operational mode that detection is current, existing air-conditioned operational mode is divided into heating mode, air supply pattern, system more
Cold mode and dehumidification mode, wherein heating mode and air supply pattern do not generate condensed water, and can generate under refrigeration mode cold
Condensate can generate a large amount of water under dehumidification mode, therefore, if heating mode or air supply pattern, then not start water pump, if
Dehumidification mode then starts water pump, if refrigeration mode, then continues the yield for calculating condensed water.
Secondly, air conditioner operation total time t, the i.e. time of the accumulative operation of air conditioner are then calculated, if fortune if refrigeration mode
Row total time t > ts, then open water pump；Because accumulative with air conditioning usage time, it is also easy to produce dirty stifled in air-conditioning, condensed water is easier to
Generate and be not easy to be discharged, cause cabinet internal drainage it is unsmooth there are part waters, so that opening the water pump 1 at this time can effectively prevent
The only risk that condensed water goes out slowly.
Finally, detecting the operating parameter and environmental parameter of air-conditioning if t < ts, calculated according to operating parameter and environmental parameter
The yield of condensed water under current operating conditions, and the threshold value comparison with setting then start the water pump 1 if more than threshold value.
Herein it should be noted that the threshold value can be set as needed, meanwhile, it can be changed according to operation total time, because being transported with air-conditioning
The row time adds up, and Auto-drainage performance can be declined, and therefore, threshold value can subtract therewith with the increase of operation total time
It is small.
The actuator 2 is electrically connected with the reservoir 3, detection components 4 and water pump 2, so as to receive
The parameters that detection components 4 detect are stated, and execute the pre-set programs in the reservoir 3, are calculated under current operating conditions
The yield of condensed water, and make comparisons with the threshold value of setting, judge whether to need to open the water pump 1.
With reference to Fig. 3, because air conditioner needs to carry out efficiency test, therefore, air conditioner of the present invention be divided into test mode and
Use state, under test mode, air conditioner of the present invention does not need to consider the problems of to use the time, it is only necessary to consider operation
Mode, and environment is more single when test, it is only necessary to the frequency for considering the frequency converter 5, i.e., under test mode, only described in detection
The frequency of frequency converter 5 and the yield that condensed water is calculated according to frequency, and the threshold value comparison with setting, judge whether to need to start
Water pump can test the Energy Efficiency Ratio under each state.
By certain European Union to for 12K frequency conversion smallpox unit machine, standard configuration water pump idle running power is 7W, and efficiency test needs
To test respectively SEER A, SEER B, SEER C and SEER D tetra- fixed test and then calculate frequently final SEER value.
Under SEER mode A, air conditioner dehumidification amount is about 1.5kg/h, and under SEER B-mode, air conditioner dehumidification amount is about
Under 0.5kg/h, SEER C mode, air conditioner dehumidification amount is < 0.1kg/h, and under SEER D mode, air conditioner dehumidification amount is 0, indoor unit
Drip tray can water-holding quantity > 1.0kg, air conditioner refrigeration determine the frequency testing time and is usually no more than 3h, and efficiency test is using new engine
It is tested, therefore the dirty risks such as stifled.
Therefore in SEER A and SEER B-mode, water pump is opened, and is switched off the pump in SEER C and SEER D operating condition,
Unnecessary power input can be effectively reduced.
By above-mentioned change, the efficiency of SEER C can be increased by 6.45W/W is 6.63, increases 2.8%；SEER D
Efficiency by 10.00 increase be 10.75, increase 7.5%；It is 5.83 that whole SEER is increased by 5.69, increases 2.5%.
Air conditioner of the present invention, by the detection to operating status, and the calculating to condensed water yield, cold
Condensate yield, which reaches, restarts water pump 1 when needing to be discharged, the efficiency for effectively increasing air conditioner is horizontal；By detection, not
Water pump 1 is not started under necessary state, the Energy Efficiency Ratio of air conditioner greatly promotes；Because condensed water will not be generated under heating mode, pass through
Judgement control to operational mode, can be effectively reduced operation power；By the detection for operation total time and judge to open
Dynamic water pump, the caused condensed water that retains that the dirty stifled rear condensed water of air-conditioning can be effectively prevented overflow.
With reference to Fig. 2, a kind of air-conditioner control method includes the following steps: to detect current operating status and calculates the fortune
The yield of condensed water under row state starts water pump if the yield of condensed water is greater than threshold value.
Firstly, the operational mode that detection is current, existing air-conditioned operational mode is divided into heating mode, air supply pattern, system more
Cold mode and dehumidification mode, wherein heating mode and air supply pattern do not generate condensed water, and can generate under refrigeration mode cold
Condensate can generate a large amount of water under dehumidification mode, therefore, if heating mode or air supply pattern, then not start water pump, if
Dehumidification mode then starts water pump, if refrigeration mode, then continues the yield for calculating condensed water.
Secondly, air conditioner operation total time t, the i.e. time of the accumulative operation of air conditioner are then calculated, if fortune if refrigeration mode
Row total time t > ts, then open water pump；Because accumulative with air conditioning usage time, it is also easy to produce dirty stifled in air-conditioning, condensed water is easier to
Generate and be not easy to be discharged, cause cabinet internal drainage it is unsmooth there are part waters, so that opening the water pump 1 at this time can effectively prevent
The only risk that condensed water goes out slowly.
Finally, detecting the operating parameter and environmental parameter of air-conditioning if t < ts, calculated according to operating parameter and environmental parameter
The yield of condensed water under current operating conditions, and the threshold value comparison with setting then start the water pump 1 if more than threshold value.
