The main member that utilizes the domestic variable frequency cold type air conditioner of above-mentioned cold EGR shown in Figure 2: after the domestic variable frequency cold type air conditioner energising starting, the opposite side connection outdoor heat exchanger of the four-way spare 5 that is connected with the compressor 1 of compression refrigerant is a condenser 2; Opposite side connection indoor heat exchanger at the expansion mechanism 3 that is attached thereto is an evaporimeter 4; Evaporimeter 4 is connected an other side of above-mentioned four-way spare 5 again, and a remaining side of four-way spare 5 is connected with compressor 1.In outdoor heat exchanger is that the side of condenser 2 is provided with outdoor fan 6, is provided with indoor fan 7 and indoor heat exchanger is the side of evaporimeter 4.
As mentioned above, the direction of domestic variable frequency cold type air conditioner change four-way spare 5 changes the function that is installed in indoor interior heat exchanger 4 and reaches the indoor purpose of changes in temperature.When opening warm braw, passes through by domestic variable frequency cold type air conditioner the starting of compressor 1, refrigerant is a compressor 1 by the direction of arrow A, and------------order of compressor 1 circulates outdoor heat exchanger 2---four-way spare 5---expansion mechanism 3 indoor heat exchanger 4 four-way spare 5, thereby indoor heat exchanger 4 plays the effect of condenser and hot gas is discharged into indoor, keeps indoor warm state.When if domestic variable frequency cold type air conditioner is opened cold wind, the direction that changes four-way spare 5 makes refrigerant flow by the direction of arrow B; The effect that this moment, indoor heat exchanger 4 played evaporimeter is discharged into the indoor indoor nice and cool state of keeping to cold air.
Therefore, with the domestic variable frequency cold type air conditioner of selecting the changes in temperature mode season, can realize the adjusting of the indoor ability of changes in temperature, control by the running frequency that changes compressor 1.
The poor effect of drying because the evaporimeter bulk temperature is high in addition, be such moisture moving control method and cold wind, control the weak wind operation that similar difference is indoor fan to room temperature, so room temperature descends and feels slight chill in the air, and the high and poor effect of drying of evaporimeter bulk temperature.
The problem that the present invention solves is, used the expansion mechanism two-port valve when closing low-frequency operation, can utilize length capillaceous to reach the control method of the dehumidification operating mode of domestic variable frequency cold and worm air conditioner of required purpose when making the dehumidifying running.
The technical solution adopted in the present invention is: the control method of dehumidification operating mode of domestic variable frequency cold and worm air conditioner is characterized in that having comprised following several stages; First: when indoor temperature reaches design temperature, reduce the compressor operating frequency and the dehumidifying phase run (S11) that carries out; Second: in above-mentioned dehumidifying phase run, compare the detection-phase (S12) of existing frequency of compressor and setpoint frequency X; The the 3rd: in detection-phase, if existing frequency then is located at the dwell period (S13) of the two-port valve of expansion mechanism less than setpoint frequency X; The the 4th: in above-mentioned two-port valve dwell period, periodically detect the phase run (S14) that whether dehumidifies, if then keep former two-port valve closed condition; The the 5th: if not the detection-phase (S15) of the drive manner that then stops to dehumidify.
The domestic variable frequency cold type air conditioner that the present invention sets forth can reduce humidity when selecting the dehumidifying drive manner but can not make indoor temperature low excessively, and the phenomenon of the poor effect that prevented to dry because of evaporator temperature is too high.

The specific embodiment
Be described in detail as follows below with reference to chart:
As shown in Figure 3, be applicable to that the main member of freezing cycle device of the domestic variable frequency cold type air conditioner among the present invention is as follows: the compressor 1 that the gaseous state refrigerant of low-temp low-pressure is transformed into high temperature and high pressure gas state refrigerant; The refrigerant that has become the high temperature and high pressure gas state by compressor 1, be converted into the condenser (outdoor heat exchanger) 2 of high temperature high pressure liquid state refrigerant; The refrigerant that becomes the high temperature high pressure liquid state, be converted into low-temp low-pressure liquid condition refrigerant and the expansion mechanism 3 of inner heat release by condenser 2; Become the refrigerant of low-temp low-pressure liquid condition by expansion mechanism 3, be converted into low-temp low-pressure gaseous state refrigerant and suck the evaporimeter (indoor heat exchanger) 4 of outside heat; In addition, open-minded when in the expansion mechanism 3 that constitutes by capillary, being provided with cold wind, the two-port valve 8 of closing during warm braw; The warm braw capillary pipe length is longer than cold wind capillary pipe length.
As shown in Figure 4, the control method of domestic air conditioner dehumidifying drive manner comprised as the next stage among the present invention:
The S11 stage---when indoor temperature reaches design temperature, reduce the compressor operating frequency and the dehumidifying phase run that carries out; S12---in above-mentioned dehumidifying phase run, compare the detection-phase of existing frequency of compressor and setpoint frequency X; S13---in detection-phase, if existing frequency then is located at the dwell period of the two-port valve of expansion mechanism less than setpoint frequency X; S14---in above-mentioned two-port valve dwell period, periodically detect the phase run that whether dehumidifies; If S15---then keep former two-port valve closed condition, if not the detection-phase of the drive manner that then stops to dehumidify.
As mentioned above, adopt the control method of domestic air conditioner dehumidifying drive manner among the present invention, what are also long compared with the long capillary length of cold wind low frequency because of the warm braw capillary pipe length, and finish evaporation process later in the evaporimeter middle part, so almost there is not heat exchange with the room air that sucks by the liquid cooling matchmaker of evaporimeter (indoor heat exchanger).Because of the capillary pipe length that extended, the temperature of evaporator inlet is reduced in addition, further reduced the surface temperature of evaporator inlet side, thereby reached the effect of effectively drying.Promptly reduce the cold wind ability and further reduce evaporator surface temperature and reach the effect of effectively drying.
