At first, in heat drying turns round again, at step S1, to the temperature of the front face side heat exchanger 11 that works as evaporimeter whether the low problem of dew-point temperature obtained according to indoor temperature and humidity of beguine judge that this indoor temperature and humidity are measured by each sensor 27,28.At this moment, in front under the high or situation about equating of the temperature of side heat exchanger 11, might the dehumidifying effect deficiency, so enter step S2, the blind window 22 that is used as the air quantity controlling organization begins to carry out air quantity and distributes control, makes enter the mouth 19 aperture stenosis of front suction.Then, enter step S3,,, return step S1 again, judge whether to carry out air quantity and distribute control through behind the above-mentioned certain hour until till the operating condition under the above-mentioned aperture is stable, keeping this state (about 10 minutes).On the other hand,,, do not distribute control, keep present situation (step S4) so do not need to carry out air quantity with above-mentioned blind window 22 if the dew-point temperature height then has sufficient dehumidifying effect at step S1.Through behind the certain hour, return step S1 again.
According to said method, the ratio that at first makes the air quantity that passes through to each heat exchanger 10,11 when beginning is to begin the common running of heat drying more definitely substantially.At this moment, do not carry out air quantity control from the beginning, this is because of the air quantity that passes through to front face side heat exchanger 11 from the beginning reduces overall running ability to be reduced in order to prevent.In addition, according to this form of implementation, under or the situation about equating high, automatically reduce the aperture of front suction inlet 19 by blind window 22 in the dew-point temperature of obtaining according to indoor temperature and humidity as the temperature beguine of the front face side heat exchanger 11 of evaporimeter, reduce sucking air quantity, so adjust.Therefore, can limit the heat exchange of front face side heat exchanger 11, reduce the temperature of front face side heat exchanger 11, the result can improve moisture removal.In addition, the aperture that above-mentioned front suction inlet 19 is undertaken by blind window 22 is regulated and is carried out serially, carries out above-mentioned air quantity repeatedly and distributes control, until the heat drying running is carried out on indoor limit heating wind, limit again.In addition, even under the situation of carrying out above-mentioned running,, also carry out above-mentioned judgement and control at regular intervals usually in order to continue this state.According to above-mentioned situation, for to indoor heating wind, even if the condensation temperature of the rear side heat exchanger 10 that works as condenser is risen, by the air quantity controlling organization, the temperature of the front face side heat exchanger 11 that works as evaporimeter is descended, or suppress temperature and rise, so can under the situation that does not reduce moisture removal, positively carry out again the heat drying running.As a result, can realize the indoor environment that the user wishes, improve comfortableness.In addition, if control the temperature of front face side heat exchanger 11 in this wise, even the advantage that can obtain certain effect on moisture extraction is also arranged when the common running of heat drying again.
More than, concrete form of implementation of the present invention is illustrated, but the present invention is not limited to above-mentioned form of implementation, can do all changes within the scope of the invention and implement.At first, in above-mentioned form of implementation, judge whether that carrying out air quantity control by the air quantity controlling organization time is by judging making comparisons as the temperature of the front face side heat exchanger 11 of evaporimeter and dew-point temperature, but also can be by being that necessary evaporating temperature below 50% is made comparisons and judged for making indoor humidity whether to the temperature of front face side heat exchanger 11.In this case, necessary evaporating temperature also can be obtained with sensor etc., but also can consider pre-set specified temps such as user mode.
In addition, in above-mentioned form of implementation, the air quantity that the air quantity controlling organization adopts blind window 22 controls to supply with from the front suction inlet, but as shown in Figure 3, also can control the suction air quantity by establish front cover 30 on above-mentioned indoor set, this front cover can be from outer side covers front suction inlet 19.That is, above-mentioned front cover 30 has makes the plate that roughly the is rectangle shape at the above-below direction slight curvature, and its recess is towards being configured medially, and its bottom is installed on the housing 15 of 19 times quadrate parts of front suction inlet pivotally.In addition, be provided with the gyroaxis 32 of motor at the center of the installation portion 31 that above-mentioned front cover 30 is installed, by CD-ROM drive motor, above-mentioned front cover 30 is that the center is to inside and outside revolution with the gyroaxis 32 of installation portion 31.Therefore, by the revolution of above-mentioned front cover 30, can regulate the aperture of front suction inlet 19, control sucks air quantity.
According to said method, air quantity by the front face side heat exchanger 11 that works as evaporimeter is controlled, promptly, the air quantity that sucks from front suction inlet 19 is reduced, reduce the temperature of above-mentioned front face side heat exchanger 11 like this, improve moisture removal, but flow into the pressure of the cold-producing medium of front face side heat exchanger 11 by control, also can reduce the evaporating temperature of front face side heat exchanger 11, improve moisture removal.For example, utilization is located at the mechanism of decompressor 12 of refrigerant line entrance side of above-mentioned front face side heat exchanger 11 as pressure control mechanism, aperture, increase decompression amount by reducing the above-mentioned mechanism of decompressor 12 in the evaporating temperature of side heat exchanger 11, improve moisture removal before also can reducing.According to such formation, under the situation of not adding special mechanism, can implement, so the expense that can suppress to cause because of additional structure increases.In addition, in above-mentioned form of implementation, be that indoor temperature transmitter and temperature sensor are located on the indoor set main body 14, as long as but can measure indoor temperature and humidity, be located at passable everywhere.
