Embodiment approach 1
[0018] figure 1 It is a figure which shows the structure of the dehumidification apparatus concerning Embodiment 1 of this invention. exist figure 1 In each figure described later, members attached with the same reference numerals are the same or corresponding members, and this is common throughout the entire specification. In addition, the forms of the constituent elements described in the entire specification are merely illustrative, and are not limited to these descriptions.
[0019] The dehumidifier 1 has a compressor 2, a four-way valve 3 that is a flow switching device, a first heat exchanger 4, an expansion valve 5 that is a decompression device, and a second heat exchanger 6 in a housing 10. The refrigerant circuit A is formed by being connected in a ring shape. The housing 10 is divided into an air path chamber 20 and a machine room 30 . The compressor 2 and the four-way valve 3 are arranged in the machine room 30 , and other devices are arranged in the air path ch...

[0050] (Modification 1: Components of the dehumidifier 1)
[0051] exist figure 1 In the figure, the configuration of switching the refrigerant circuit A using the four-way valve 3 is shown, but as long as the flow path of the refrigerant circuit A can be switched, it is not particularly limited to the four-way valve, and other valves may be used. For example, a structure may be adopted in which four electromagnetic valves as two-way valves are used, and each of the discharge side and the suction side of the compressor 2 is connected to the first heat exchanger 4, or the compressor 2 is connected to the first heat exchanger 4. Each portion connected to the first heat exchanger 4 on the discharge side and the suction side has a structure in which a solenoid valve is arranged. In addition, it is only necessary to realize the refrigerant circuit A and the refrigeration cycle similar to those of the present embodiment by opening and closing the solenoid valves. In addition, othe...

[0052] (Modification 2: Operation time of each operation mode)
[0053] The respective operation times of the first operation mode and the second operation mode may be predetermined times, but each operation time of each operation mode has a reasonable value according to the air condition or the operation state of the dehumidifier 1 . Therefore, the operation time of each operation mode may be determined based on the air condition or the operation state of the dehumidifier 1 so that the operation can be performed at this reasonable value.
[0054] In the first operation mode, since moisture is released from the desiccant block 7, the time required for releasing a moderate amount of water from the desiccant block 7 until the amount of moisture remaining in the desiccant block 7 becomes an appropriate amount becomes a reasonable value. . In the state where more than the appropriate amount of moisture remains in the desiccant block 7, the first operation mode is terminated and s...
