Problems solved by technology

In addition, in order to prevent air leakage between the adsorption part and the desorption part of the desiccant, a sealing structure is required to airtightly separate the boundary part between the adsorption part and the desorption part, and there are problems of increasing the size of the device and increasing the cost.
In addition, since the air path structure is used to return the air passing through the dehumidification rotor to the dehumidification rotor, it becomes an air path structure with many bends, which increases the pressure loss when conveying air, increases the power of the blower, and increases the power consumption of the device. subject

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...

Abstract

The first heat exchanger (4), the desiccant block (7) and the second heat exchanger (6) are arranged in series. Moreover, in the dehumidification operation, the following modes are alternately and repeatedly implemented: the first operation mode, the first heat exchanger (4) works as a condenser or radiator, and the second heat exchanger (6) works as an evaporator; the second heat exchanger (6) works as an evaporator; In the second operation mode, the first heat exchanger (4) works as an evaporator, and the second heat exchanger (6) works as a condenser or radiator.

Description

technical field [0001] The invention relates to a dehumidification device. Background technique [0002] Conventionally, there is an example of Patent Document 1 as a dehumidifier that dehumidifies the space to be dehumidified using adsorption and desorption by a desiccant material that absorbs and desorbs moisture. Patent Document 1 is a technique for dehumidifying by combining cooling and heating by the heat exchanger of the refrigeration cycle and adsorption and desorption by the dehumidification rotor, and has the air in the dehumidification target space sequentially passing through the radiator and the dehumidification rotor of the refrigeration cycle. The air path of the desorption part of the desorption part, the evaporator of the refrigeration cycle, and the adsorption part of the dehumidification rotor. [0003] Heat the air taken into the dehumidification target space in the air duct by the radiator, humidify the heated air by the desorption part of the desiccant ...
