- the principle of dehumidification in the indirect evaporative cooling unit 4 will be described.
- the outlet temperature of the product air PA is the temperature shown in (1) in Fig. 49 (35 in this example). From (° C), the relative humidity will approach 100% RH at the same time as it is cooled to the specified dew point temperature shown in (2).
- FIG. 50 is a flowchart showing an example of dehumidification control. A specific control example will be described with reference to FIGS. First, it is assumed that the setting switch 75 is operated and a desired setting humidity value is registered in the memory 77 in advance. In addition, it is assumed that the fan motor 3 and the like are driven to perform a cooling operation.
- Step SHI CPU71B reads the humidity of product air PA from humidity sensor 17b.
- Step SH2 The CPU 71B determines the force at which the humidity of the product air PA read from the humidity sensor 17b has reached a predetermined humidity. In this example, it is judged whether the humidity of the product air PA has become more than 100% RH relative humidity.
- Step SH3 When the CPU 71B determines that the humidity of the product air PA has reached the predetermined humidity, it determines whether to execute the dehumidifying mode. Whether to perform dehumidification mode now Is preset by an operation of the setting switch 75 or the like.
- Step SH4 When the CPU 71B determines that the dehumidification mode is not executed, the flow rate of the working air WA of the indirect evaporative cooling unit 4 shown in FIG. .
- the CPU 71B reduces the flow rate of the working air WA by controlling the damper motor 73 to reduce the opening degree of the exhaust flow rate adjustment damper 15.
- the flow rate of the product air PA may be increased.
- the temperature control of the product air PA can be performed not only by controlling the opening of the flow adjustment damper but also by controlling the fan air volume.
- the temperature of the product air PA does not decrease by temporarily stopping the fan motor 3 to stop the ventilation operation.
- Step SH5 When the CPU 71B determines to execute the dehumidifying mode, it reads the set humidity value from the memory 77.
- Step SH6 The CPU 71B reads the temperature of the product air PA from the temperature sensor 17a.
- Step SH7 The CPU 71B detects the current dehumidification amount from the temperature of the product air PA read from the temperature sensor 17a, and compares the current dehumidification amount with the set humidity value read from the memory 77.
- the procedure for detecting the dehumidification amount from the temperature of the product air PA is explained.
- the temperature detected by the temperature sensor 17a is the temperature shown in (3) in Fig. 49
- the absolute humidity shown in (3) The amount of dehumidification can be detected from the difference in absolute humidity shown in (1).
- the absolute humidity at the point (3) is about 15gZkg (DA) and the absolute humidity at the point (1) is about 18gZkg (DA). Therefore, the temperature detected by the temperature sensor 17a is indicated by (3). It can be seen that it is dehumidified by about 3gZkg (DA). This makes it possible to detect the current absolute humidity. wear.
- the humidity of the product air PA can be controlled to a desired humidity by detecting the dehumidification amount from the temperature detected by the temperature sensor 17a.
- Step SH8 If CPU71B determines in step SH7 that the humidity is larger than the set humidity value (absolute humidity) read from the current absolute humidity memory 77, the temperature of the product air PA is lowered to lower the absolute humidity. Therefore, for example, increase the flow rate of the working air WA of the indirect evaporative cooling unit 4 shown in FIG. For example, the CPU 71B increases the flow rate of the working air WA by controlling the damper motor 73 to increase the opening of the exhaust flow rate adjustment damper 15.
- the temperature of the product air PA decreases as described above.
- the outlet temperature of the product air PA decreases along the line with a relative humidity of 100% RH shown in FIG. 49, and the amount of moisture condensed in the product air PA increases, so that it passes through the indirect vaporization element 11.
- Product Air The absolute humidity of the PA decreases.
- the product air PA is supplied as the supply air SA to the room 102 such as the living room 112 shown in FIG. 8 or the like. Therefore, by dehumidifying the supply air SA, the absolute humidity of the supply air SA is set as the set humidity. It can be supplied to the room 102.
- Step SH9 If CPU71B determines in step SH7 that it is smaller than the set humidity value (absolute humidity) read from the current absolute humidity memory 77, it raises the product air PA temperature and raises the absolute humidity. Therefore, for example, the flow rate of the working air WA of the indirect evaporative cooling unit 4 shown in FIG. For example, the CPU 71B reduces the flow rate of the working air WA by controlling the damper motor 73 to reduce the opening of the exhaust flow rate adjustment damper 15.
