Abstract

The present invention provides an air conditioner having a heating and humidifying function by adding a minimum number of members to a system for dehumidification and cooling without adding a significant number of functional members.
A hot water coil is disposed upstream or downstream of a dehumidification rotor on the processing side of the unit. Since the outside air is dry during the winter and dry seasons, it is generally not necessary for the air conditioner to dehumidify during the winter and dry seasons. Therefore, it is not necessary to operate the dehumidification rotor in the winter and dry seasons. The air to be treated simply passes through the dehumidification rotor and is not dehumidified even if it passes. The air after passing through the dehumidification rotor passes through a hot water coil disposed downstream of the dehumidification rotor. In the winter and dry seasons, hot water of about 50 ° C. to 90 ° C. flows through the hot water coil, so that air passing through the hot water coil is heated by the hot water coil.

An embodiment of an integrated unit of an air conditioner according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of an integrated unit. FIG. 2 is a schematic explanatory diagram of the integrated unit of the present invention as a cooling device during cooling in summer , and FIG. 3 is a schematic explanatory diagram of the integrated unit of the present invention as a winter heating device .

  As shown in FIG. 1, the integrated unit of the present invention includes a processing side passage for introducing outside air and a regeneration side. A dehumidifying rotor 1 is disposed across the passage. Filter F that draws outside air into the processing-side passage 1 intake port 2, fan motor 3, dehumidifying rotor 1, heat exchanger hot water coil 4, indoor An indirect evaporative cooler 5 having an exhaust part 6 for exhausting cool air is disposed in the exhaust part 6. An exhaust port 7 provided with a damper V1 for opening and closing the exhaust to the room and an open and close damper for exhausting to this side An exhaust port 8 provided with a par V2 is arranged, and these dampers V1 and V2 are linked. It has become.

  On the other hand, on the regeneration passage side, a filter for introducing outside air for regenerating the dehumidifying agent in the dehumidifying rotor 1 A vent 9 provided with F2, a hot water coil 10 for heat exchange for heating this air, and a dehumidifying rotor 1 are passed through. A fan motor 11 for exhausting excess regeneration air is disposed. 12 is indirect vaporization cooling This is the air supply port of the vessel 5. Reference numeral 13 denotes an exhaust port for regeneration air.

  The air heated by the hot water coil is then fed into an indirect vaporizer cooler. This indirect vaporizer cooler is primarily intended to cool the air. As described in Japanese Patent No. 3559255, this indirect vaporizer is divided into a layer that causes a vaporization phenomenon and a layer that cools the air. If dehumidification and cooling are required, the vaporization phenomenon Since the air that passes through the layer that has caused the vaporization is the air after causing the vaporization phenomenon, this air is discarded as exhaust. When heating and humidification are required, the air to be exhausted is used as supply air without being exhausted. Originally, the air to be exhausted is air after the vaporization phenomenon has occurred, and is therefore highly humid air. Therefore, this air is used for air supply for the purpose of humidification.

In the processing side passage of the unit, placing the hot water coil 4 under flow of the dehumidifying rotor 1. Since the outside air is dry during the winter and dry seasons, it is generally not necessary for the air conditioner to dehumidify during the winter and dry seasons. Therefore, it is not necessary to operate the dehumidification rotor 1 in the winter and dry seasons. The air to be treated simply passes through the dehumidifying rotor 1 and is not dehumidified even if it passes. The air that has passed through the dehumidifying rotor 1 passes through a hot water coil 4 disposed downstream of the dehumidifying rotor 1 . Winter, the dry season, because the hot water coil 4 is 50 ° C. to 90 ° C.-position hot water flows, the air passing through the hot water coil 4 is heated by the hot water coil 4.

An integral unit of the present invention places the temperature water coil 4 downstream of the dehumidifying rotor 1. In the winter and dry seasons, the hot water produced by a separate heat source flows to the hot water coil 4 without flowing to the hot water coil 10 . The air is heated (heated) through the hot water coil 4 .

The heated air is fed into the indirect vaporizer cooler 5 of FIG.
This indirect vaporizer cooler is primarily intended to cool the air. As described in Japanese Patent No. 3559255, this indirect vaporizer is divided into a layer that causes a vaporization phenomenon and a layer that cools the air. If dehumidification and cooling are required, the vaporization phenomenon Since the air that passes through the layer that has caused the vaporization is the air after causing the vaporization phenomenon, this air is discarded as exhaust. When heating and humidification are required, the air to be exhausted is used as supply air without being exhausted. Originally, the air to be exhausted is air after the vaporization phenomenon has occurred, and is therefore highly humid air. Therefore, this air is used for air supply for the purpose of humidification.

Of the air introduced into the indirect vaporizer 5 during the dehumidification and cooling, the high-humidity air after causing a vaporization phenomenon of 30 to 50% is exhausted from the discharge port 7 outside the apparatus. When heating or humidification is required, this exhausted air is used, so this air is not exhausted into the atmosphere . A damper V1 is installed at the exhaust port 7 in FIG. 1 , and the damper V1 is closed. At the same time, another damper V2 is installed on the side surface of the exhaust port 8 , and this damper V2 is opened. When the damper V2 is opened, the air to be exhausted flows from the damper V2 toward the air supply to the room. Here, is mixed with air coming out from the air supply layer between contact type evaporative cooler 5, mixed air is supply to the indoor from the discharge port.

As a specific method to be used, the damper V2 installed at the exhaust port 7 of the exhaust unit 6 of the indirect vaporizer cooler 5 is closed. On the other hand, another damper V2 is provided on the way to the exhaust port. The damper V1 of the exhaust port 7 that needs to be dehumidified and cooled is opened, and the other damper V2 is closed. On the other hand, when heating and humidification are required, the damper V1 of the exhaust port 7 is closed and the other damper V2 is opened, and the high temperature and high humidity passing through another layer of the indirect vaporizer 5 mixed with air, is used as supply air from the unit.

At the time of dehumidification and cooling, when the amount of air sent to the indirect vaporizer cooler 5 is set to 100, 30 to 50% is discarded as exhaust, so the air supply amount is 50 to 70% of the inlet air. However, when heating and humidification, if the amount of inlet air is 100, this total amount becomes the air supply amount.
