On the other hand, when the outside air humidity detected by the outside air humidity sensor 23 is higher than 90%, even if the outside air is blown into the humidifying hose 4, the inside of the humidifying hose 4 cannot be sufficiently dried and the efficiency is poor. Do not. In addition, when the outside air humidity detected by the outside air humidity sensor 23 cannot dry the inside of the humidification hose 4 efficiently at 60% or more, the outside air blown into the humidification hose 4 is supplied to the heater 17. By heating. This provides a humidifying apparatus and an air conditioner using the same, which can prevent condensation in the humidification hose even when the humidification operation is not performed.

Description

Humidification device and air conditioner using same {HUMIDIFIER AND AIR CONDITIONER USING THE HUMIDIFIER}

Conventionally, as a humidifier, there exists a thing which supplies humidifying air from the outdoors to the room. The humidifier adsorbs moisture to the humidifying rotor from the outside air in the outdoor, and then dehumidifies the moisture from the humidifying rotor and supplies humidified air to the room through the humidifying hose. By doing so, the relative humidity in the room can be adjusted, and the comfort in the room is improved. By the way, in the said humidification apparatus, there exists a problem that the dew condensation water in a humidification hose stays.

Therefore, the applicant prevents the condensation water from remaining in the humidification hose by alternately repeating the humidification operation for supplying the humidification air from the outdoors to the interior via the humidification hose and the drying operation for blowing the dry air into the humidification hose. A humidifier that can do this has been proposed. In addition, this humidifier is demonstrated in order to make this invention easy to understand, and it is not a well-known technique and it is not a prior art.

By the way, in the humidifier, in the summer where no humidification operation is required, when the outside air of high temperature and high humidity flows into the humidifying hose, and the room temperature is lower than the outside air by cooling, the inside of the humidifying hose condenses and condensates. There is a problem that the water stays.

The present invention relates to a humidifier for supplying humidified air indoors and an air conditioner using the same.

On the other hand, during the summer cooling operation, the humidification fan 15 is operated in a state where the humidification rotor 11 is stopped at predetermined time intervals, and a drying operation is performed in which outside air is blown into the humidification hose 4 to perform high temperature and high humidity. The outside air flows into the humidifying hose 4 to prevent condensation on the indoor side and to prevent the condensation water from remaining.

3 and 4 show flowcharts showing the drying operation process during the cooling operation without the humidification operation of the humidifier 3.

First, when the cooling operation starts, it is determined whether 20 minutes have elapsed since the start of processing in step S1, and when 20 minutes have not elapsed, step S1 is repeated, and when it is determined that 20 minutes has elapsed, the step ( Proceed to S2).

Next, in step S2, it is determined whether the outside air temperature is higher than the room temperature, and if it is determined that the outside air temperature is higher than the room temperature, the flow advances to step S3, and when it is determined that the outside air temperature is below the room temperature, Step S2 is repeated. In addition, in step S2, you may make it a condition when it is larger than fixed temperature more than outdoor temperature and indoor heat exchanger temperature.

Next, the humidification fan is operated in step S3 to blow external air into the humidification hose 4.

Next, the process proceeds to step S4, the timer T1 is started, the process proceeds to step S5, and the timer T2 is started. Here, the timer T1 clocks the minimum drying operation time, and the timer T2 clocks the maximum drying operation time.

Next, when it is determined whether the extraction humidity detected by the extraction humidity sensor 21 is 80% or more, and determines that the extraction humidity is 80% or more, the flow advances to step S8, and the heater 17 is turned on. do. On the other hand, if it is determined in step S6 that the extraction humidity is less than 80%, the flow advances to step S7 to turn off the heater 17. In other words, if the blowout humidity of the humidifying hose 4 immediately after the operation of the humidifying fan 15 is 80% or more, it is determined that the drying capacity is not sufficient, and the heater 17 is turned on.

Next, the process proceeds to step S9, and it is determined whether or not the count of the timer T1 has ended. If not, the process returns to step S6, and when the process ends, the process shown in FIG. Proceed to S10.

Next, in step S10 shown in FIG. 4, it is determined whether the blowout humidity detected by the blowout humidity sensor 21 is 60% or less, and when it is determined that the blowout humidity is 60% or less, the flow advances to step S11. On the other hand, if it is determined that the blowout humidity exceeds 60%, the flow advances to step S12.

If it is determined in step S11 whether the gradient of take-out humidity is downward, and if it is determined that the gradient of take-out humidity is downward, the flow advances to step S12, and if it is determined that the gradient of take-out humidity is not downward, The flow advances to step S13. That is, if the gradient of take-out humidity is not downward, it indicates that the dew condensation water in the humidification hose 4 has disappeared, thereby determining the end time of the drying operation.

On the other hand, in step S12, it is determined whether or not the count of the timer T2 has ended. If not, the process returns to step S10, and if it is finished, the process proceeds to step S13.

Next, the heater 17 is turned off in step S13, and the humidification fan 15 is stopped in step S14.

Next, the flow advances to step S15 to monitor the taking out humidity, and the flow advances to step S16 to determine whether the monitored takeout humidity is 90% or more. If it is determined in step S16 that the extraction humidity is 90% or more, the flow advances to step S17, and if it is determined that the extraction humidity is less than 90%, the flow returns to step S15. As a result, if the take-out humidity of the humidification hose 4 is higher than 90% even after the humidification fan 15 is stopped, it is determined that a drying operation is necessary, and the flow proceeds to the next drying operation.

Next, the interval timer T3 is started in step S17, the flow advances to step S18, and it is determined whether or not the count of the interval timer T3 is finished. If it is determined in step S18 that the count of the interval timer T3 has ended, the process returns to step S2 shown in FIG. 3, and if it is determined that the count of the interval timer T3 has not ended, step S18. Repeat.
