Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only It is a part of the embodiment of the present invention, instead of all the embodiments.
Embodiment one
Fig. 1 is the flow chart of dehumidification control method provided in this embodiment.As shown in Figure 1, present embodiments providing one kind Dehumidification control method, realization are reached dehumidifying and energy conservation under constant temperature and humidity state, are executed using constant temperature and humidity device, the device It is made of software and/or hardware, is generally integrated in inside air conditioner.
Include the following steps:
S10: if the practical relative humidity (RH is practical) obtained is higher than setting relative humidity (RH setting), refrigeration is opened.
Practical relative humidity is obtained by warm and humid sensor, the value for setting relative humidity is set according to human comfort. With reference to the prior art, the operation of making comparisons yet by practical relative humidity with setting relative humidity of the refrigerating capacity of dehumidifying is obtained.It opens After opening refrigeration, further includes: S11, if practical relative humidity and set relative humidity difference it is larger, enhance refrigeration.
S12: judge that the practical absolute humidity (AH is practical) obtained is to prohibit whether lower than setting absolute humidity (AH setting) Only freeze and opens heating.
Restrictive condition of the relationship of setting absolute humidity and practical absolute humidity as dehumidifying is calculated in real time.Correspondingly, should Before step, further includes:
Obtain actual temperature.According to practical relative humidity and actual temperature (T is practical), practical absolute humidity is calculated.According to Relative humidity and set temperature (T setting) are set, setting absolute humidity is calculated.
Specifically, the practical absolute humidity is equal under practical relative humidity and actual temperature may with reference to well-known technique The product of the maximum absolute humidity reached;The setting absolute humidity, which is equal under setting relative humidity and set temperature, to be likely to be breached Maximum absolute humidity product.
The present embodiment is by judging the relationship control refrigeration of practical absolute humidity and setting absolute humidity and the unlatching of heating Or close, it can prevent temperature from continuing to decline under the working condition of dehumidifying, so that relative humidity is close or equal to setting Relative humidity.On the one hand the purpose for realizing dehumidifying can effectively reach the dehumidification requirements of annual weather, on the other hand realize section Can be reliable, unnecessary waste can be reduced.
Embodiment two
Fig. 2 is the flow chart second embodiment of the present invention provides dehumidification control method.As shown in Fig. 2, the present embodiment is to above-mentioned Embodiment is improved, and is increased actual temperature operation and relative humidity compared with set temperature and is less than or equal to setting phase Operation to humidity.Method includes the following steps:
S20: if the practical relative humidity (RH is practical) obtained is higher than setting relative humidity (RH setting), refrigeration is opened.
S21: if the difference of practical relative humidity and setting relative humidity is larger, enhance refrigeration.
S22: judge whether practical relative humidity is below or equal to setting relative humidity.If so, refrigeration is closed, if It is no, then follow the steps S23.
After closing refrigeration, practical relative humidity is still obtained in real time, and circulation executes step S20, keeps at indoor environment In the state of constant temperature and humidity.
S23: judge that the practical absolute humidity (AH is practical) obtained is to prohibit whether lower than setting absolute humidity (AH setting) Only freeze and opens heating.
S24: obtaining actual temperature, judge whether actual temperature is greater than set temperature, if so, executing step Otherwise S25 continues to execute origin operation.
S25: releasing is forbidden freezing and closing heating.
When practical absolute humidity has reached requirement lower than absolute humidity, the absolute water content in air is set;Close system Cold and after opening heating, when temperature rises to set temperature, practical relative humidity can drop to setting rh value, at this time Also refrigeration is forbidden in releasing, the recyclable operation of device.
The present embodiment by the relationship of setting actual temperature and set temperature come the case where knowing practical relative humidity, thus Whether the practical relative humidity of timely learning drops to setting relative humidity.Meanwhile it being set when practical relative humidity is below or equal to When determining relative humidity, refrigeration is closed in time.Real-time control dehumidifying, so that indoor environment is continuously in the state of constant temperature and humidity, The phenomenon that low temperature environment can not effectively dehumidify can be improved.
