摘要:
There is provided a humidification device capable of performing humidification in as short a time as possible when an indoor humidity is low. A humidification device (10) includes operation control means (90) for selecting either a humidification priority mode or a normal operation mode based on a predetermined condition to operate the humidification device (10), and fans (34, 35) that can adjust airflow rates, and generates airflow passing through a condenser and an evaporator, wherein operation in the humidification priority mode is operation in which the airflow rates of the fans (34, 35) are decreased, as compared with operation in the normal operation mode, by which desorption of moisture from an adsorbent of the condenser and collection of moisture by an adsorbent of the evaporator are promoted, as compared with operation in the normal operation mode, so that humidification is given priority over ventilation.

A humidity control and ventilation device (10) includes: a determiner (103) determining that another ventilation device (80, 90) has turned on, if at least one of an increasing variation in the rotation speed of the air supply fan (26) and an increasing variation in the rotation speed of the exhaust fan (25) exceeds a corresponding one of predetermined values while the air supply fan (26) and the exhaust fan (25) are under the constant airflow rate control; and an air-flow-rate controller (101) decreasing one of the rotation speed of the air supply fan (26) or the rotation speed of the exhaust fan (25) if the determiner (103) determines that the ventilation device (80, 90) is on, such that a total air supply rate and a total air exhaust rate in the ventilation target space (S) are balanced with each other.

Provided is a refrigerant channel switching unit including a unit case (33) having a case body (34) and an electrical component box (35) attached to the case body (34), and a channel switching valve (EV1, EV2, EV3) housed in the unit case (33). The electrical component box (35) is attachable to the case body (34) at a first position, where the electrical component box (35) blocks one of faces of the case body (34) entirely, and a second position, where a maintenance opening (39) is formed in a part of the one face of the unit case (33). The electrical component box (35) may be retained temporarily at the second position so as to facilitate the maintenance of the channel switching valve (EV1, EV2, EV3).
摘要:
An intermediate unit (130) is disposed between an outdoor unit (110) and a plurality of indoor units (120) and is configured and arranged to switch flow of refrigerant. The intermediate unit (130) includes a plurality of first units (71) and a plurality of liquid communicating units (73). The first units (71) are connected to a high-low pressure gas communicating pipe (13) and a suction gas communicating pipe (12), both of which extend from the outdoor unit (110). Every adjacent two of the first units (71) extends approximately in parallel to each other at a predetermined first distance (dl). Each of the liquid communicating units (73) is connected at one end to a liquid communicating pipe (11) extending from the outdoor unit (110), and is connected at the other end to a liquid pipe (LP) extending to each of the indoor units (120). Every adjacent two of the liquid communicating units (73) extends approximately in parallel to each other at the predetermined first distance (dl). The first units (71) and the liquid communicating units (73) are alternately disposed.

A BS unit (70) is disposed between an outdoor unit (110) and an indoor unit (120), and includes a first part (R1), a second part (R2), a third part (R3), a liquid communicating unit (73), a first electric valve (Ev1) and a second electric valve (Ev2). The first part (R1) is connected to a suction gas communicating pipe (12). The second part (R2) is connected to a high-low pressure gas communicating pipe (13). The third part (R3) is connected to the first part (R1), the second part (R2) and a gas pipe (GP) extending to the indoor unit (120). The liquid communicating unit (73) is connected at one end to a liquid communicating pipe (11), and is also connected at the other end to a liquid pipe (LP). The first electric valve (Ev1) is mounted to the first part (R1). The second electric valve (Ev2) is mounted to the second part (R2). A minute channel (rp) is formed in the second electric valve (Ev2). The minute channel is configured and arranged to enable refrigerant to flow through the minute channel even when an opening degree of the second electric valve is set to be the lowest degree.
