The control action of-controller-
The control action that controller 60 is carried out describes.
As mentioned above, in dehumidifying ventilation operation process and in the humidification ventilation operation process, controller 60 is by controlling the switching that each air-valve 41-48, four-way change-over valve 54 carry out first action and second action.In dehumidifying ventilation operation process, controller 60 once switched first action and second action every 3 minutes; In humidification ventilation operation process, controller 60 once switched first action and second action every 4 minutes.
Like this, first action that sets in the controller 60 of present embodiment and the switching time of second action are to dehumidify the process of ventilation running than carrying out the process weak point that the humidification ventilation is turned round at interval.Its reason is described.
In the humidity control device 10 under being in dehumidifying ventilation operating condition, be used as first air and be taken into outdoor air in the housing 11, given the adsorption heat exchanger 51,52 of the effect of evaporimeter.On the other hand, in the humidity control device 10 under being in humidification ventilation operating condition, be used as first air and be taken into room air in the housing 11, given the adsorption heat exchanger 51,52 of the effect of evaporimeter.
Dehumidifying ventilation running, generally (so-called refrigeration season) carries out during indoor need refrigeration such as summer; Humidification ventilation running, generally wait in the winter time indoor need system warm during (so-called system warm season joint) carry out.And generally, the temperature and the relative humidity of refrigeration outdoor air in season are than the temperature and the relative humidity height of room air in the system warm season joint.That is to say, generally, be used as the relative humidity of air of adsorption heat exchanger 51,52 that first air has been given the effect of evaporimeter, is than humidification ventilation operation process height in the dehumidifying ventilation operation process.
On the other hand, time per unit is adsorbed the amount of the moisture of heat exchanger 51,52 absorption, is that to give the relative humidity of air of adsorption heat exchanger 51,52 high more just many more.Therefore, reach the needed time of a certain higher value since that amount that is carved into the moisture that is adsorbed heat exchanger 51,52 absorption for the moment of first action, second action, be in the process of ventilation running that dehumidifies, than short in the process of carrying out humidification ventilation running.
Time per unit is adsorbed the amount of the moisture of heat exchanger 51,52 absorption, is that adsorbance with the moisture in the adsorption heat exchanger 51,52 increases and reduces.Therefore, when the amount of the moisture that is adsorbed heat exchanger 51,52 absorption reached a certain higher value, even continue after this to supply air to adsorption heat exchanger 51,52, the adsorbance of the moisture in the adsorption heat exchanger 51,52 also almost no longer increased.That is to say that adsorption heat exchanger 51,52 reaches the saturation state of essence.Therefore, in the controller 60 of present embodiment, be set to the switching time of first action and second action at interval: shorter than humidification ventilation operation process in dehumidifying ventilation operation process.
In addition, in the controller 60 of present embodiment, establish first action in the dehumidifying ventilation running and be spaced apart 3 minutes the switching time of second action; If first action and second switching time of moving in the humidification ventilation running are spaced apart 4 minutes.But, these two values only are examples.That is to say, be interval switching time of suitably setting first action and second action according to the size of for example adsorption heat exchanger 51,52, the performance of adsorbent etc.But, preferred, with switching time of first action in the dehumidifying ventilation running and second action at interval, be set in that first action and second in the humidification ventilation running moves switching time the interval more than 60% below 90% in this scope; Be set in more than 70% more excellent in this scope below 80%.
The effect of-embodiment-
In the humidity control device 10 of present embodiment, first action in the dehumidifying ventilation running and the switching time of second action are at interval, and be shorter at interval than the switching time of first action in the humidification ventilation running and second action.That is to say that, adsorption heat exchanger 51,52 lower in the humidity of first air reaches in the long humidification operation process of saturated substantially needed time of state, sets the duration of first, second action longer.On the other hand,, adsorption heat exchanger 51,52 higher in the humidity of first air reaches the needed time of saturation state of essence than in the short dehumidifying ventilation operation process, sets the duration of first, second action shorter.
Therefore, according to present embodiment, in dehumidifying ventilation running and humidification ventilation running two operation process, can both shorten moment that adsorption heat exchanger 51,52 reaches the saturation state of essence, with move time difference in these two moment in the moment of switching to another action one of from first action and second action.Consequently, in dehumidifying ventilation running and humidification ventilation running two operation process, can both give full play to the damping ability of humidity control device 10.
