technical field

The present invention relates to a humidity control device, in particular to a humidity control device provided with a refrigerant circuit of a vapor compression refrigeration cycle.

Background technique

Conventionally, a humidity control device for adjusting air humidity using an adsorbent is known (for example, JP-A-8-189667).

This humidity control device has an air passage for circulating outdoor air or indoor air. In addition, a part of refrigerant circuit piping for circulating a refrigerant to perform a vapor compression refrigeration cycle is provided inside the air passage. The tubing within this air passage acts as an evaporator or condenser. For the air passage, a mesh container made of a mesh member in which an adsorbent is sealed is provided around the pipe.

The adsorbent in the mesh container is cooled by the refrigerant flowing into the pipeline when the pipeline functions as an evaporator. Through this cooling, moisture in the indoor air or outdoor air is adsorbed through the mesh member. And, the moisture adsorbed by the adsorbent is desorbed by heating the refrigerant flowing into the pipe when the pipe functions as a condenser. In this way, the adsorbent is regenerated.

However, in the above-mentioned conventional humidity control device, the ducts provided with the means for cooling and heating the air, and the net-like container as the moisture adsorbing means are separately formed. Therefore, in the conventional humidity control device, since the mesh container and the duct are separate components, the number of parts increases, and the structure of the entire device becomes complicated and large.

As a result, the number of components can be reduced, the structure can be simplified, and at the same time, the entire device can be downsized.

And, since the adsorbent is attached to the outer surfaces of the heat transfer tubes (15) of the first heat exchanger (3) and the second heat exchanger (5) and the outer surface of the fan (13), it is possible to use refrigerant The sorbent is cooled or heated directly. As a result, since the adsorption and desorption performance of the adsorbent can be maximized, the efficiency of adsorption and desorption can be improved, and at the same time, the size of the entire device can be reduced.

In addition, since the adsorbent is attached to the outer surfaces of the first heat exchanger (3) and the second heat exchanger (5), the dehumidification operation and the humidification operation can be continuously performed. As a result, dehumidification operation and humidification operation can be performed efficiently.

Furthermore, since eight throttle valves (35, . . . , 47, .

Furthermore, since the first inflow path (63), the first outflow path (65), the second inflow path (57) and the second outflow path (59) are symmetrically provided, flow resistance can be reduced. As a result, dehumidification and the like can be efficiently performed.

And, since the above-mentioned openings (31a-31d, 33a-33d) are opened and closed by throttle valves (35, ..., 47, ...) at positions close to the row direction, it is possible to simply configure the The distribution system can be miniaturized.

Furthermore, since the refrigerant circuit (1) of the vapor compression refrigeration cycle is used, adsorption and regeneration of the adsorbent can be performed efficiently.

In addition, since the dehumidification or humidification of the full ventilation system is performed, it is possible to perform indoor dehumidification or humidification while performing indoor ventilation.

In addition, since the dehumidification or humidification of the circulation system is performed, the indoor air can be circulated to perform indoor dehumidification or humidification. As a result, since the outside air is not taken in, it is possible to control the humidity while suppressing fluctuations in the indoor temperature.
