Description of the Related Art In recent years, in offices of intelligent buildings, a large number of automation devices (hereinafter referred to as OA devices) such as personal computers and workstations have been installed, and indoor sensible heat has increased due to heat generated from heating elements such as OA devices. Have been doing. For this reason, cooling air conditioning tends to be performed throughout the year, and the proportion of the power consumption of the air conditioning to the total power consumption is increasing. In particular, at the peak of the power consumption in summer, the power supply capacity from the power company is in a limit state, which is a serious problem. In recent years, not only air conditioning in general offices, supermarkets, department stores, etc., but also air conditioning in manufacturing factories and the need for a more comfortable air conditioning environment than ever Is a factor in increasing power consumption. For this reason, energy-saving type air conditioning systems are becoming more and more important. In particular, since there is a tendency to perform cooling and air conditioning throughout the year by heating elements such as OA equipment which are increasing in the future,
A major issue is how to use the heat of the return air heated by equipment for energy saving.

空調機８に戻る循環を行う。In a conventional air conditioning system, as shown in FIG. 5, a part of return air 1 and outside air 2 flow through dampers 5, 6, 7 provided in return air duct 3 and outside air introduction duct 4, respectively. It is controlled and taken in by the air conditioner 8. And
In the process of being supplied to the supply duct 10 by the blower 9,
2. Temperature and humidity are adjusted by the heater 13 and the humidifier 14. The temperature and humidity are adjusted, for example, at a temperature of 23 ° in summer.
C, the humidity is 50%, and in winter, the temperature is adjusted to 26 ° C. and the humidity is about 50%. The conditioned air 15 whose temperature and humidity have been adjusted is blown into the office room 16 from outlets 18 formed on the ceiling 17 of the office room 16 via the supply duct 10.
The conditioned air 15 blown into the office room 16 is the OA equipment 1
9. It absorbs heat from the heating element such as the copying machine 20 and warms up,
The air is sucked in from a return air opening 21 formed in the lower part of the side wall of the office room 16, a part of the return air 1 is exhausted out of the system by an exhaust fan 22, and the remaining return air 1 is mixed with the outside air 2 and again. The circulation returning to the air conditioner 8 is performed.

Cold heat obtained when the liquid is evaporated into the return air by the heat exchange means is used as all or a part of a cold heat source for air-conditioning an air-conditioning zone. That is, the conditioned air conditioned by the air conditioner is supplied to the air conditioning zone via the air supply path. The conditioned air supplied to the air conditioning zone
The heat is absorbed by the heat from a heating element such as an OA device, and the air is heated and sucked into the return air passage. Then, a part of the return air sucked into the return air path returns to the air conditioner, and the rest is supplied to the heat exchange means via an exhaust path.

Therefore, the return air sent to the heat exchange means is discharged out of the system through the exhaust path while evaporating the liquid into the return air by the heat exchange means. At this time, since the amount of heat corresponding to the latent heat of vaporization of the liquid is removed by the evaporation of the liquid, the heat exchanger retains cold heat corresponding to the amount of heat. Thereby, this cold heat can be used as all or a part of the cold heat source for air-conditioning the air-conditioning zone.

However, considering that return air containing the liquid is discharged out of the system, water is used. It is desirable to do. Further, cold water may be produced using the cold heat obtained by the heat exchange means, and the cold water may be used as all or a part of a cold heat source of the air conditioner. Also,
A radiation cooling panel may be provided in the air-conditioning zone, cold water may be produced by the cold heat obtained by the heat exchange means, and the cold water may be supplied to the radiation cooling panel.

The circulating water is circulated by a pipe 76 between the heat exchanger 74 and the heat transfer coil 72 provided in the air conditioner 42. That is, the heat transfer coil 72 is in a wet state with the water 68 jetted from the jet nozzle 44D, and when the return air 46 is discharged out of the system through the evaporative latent heat type heat exchanger 44, the heat transfer coil 72 The surface water 68 evaporates into the return air 46. At this time, the amount of heat corresponding to the latent heat of vaporization of the water 68 is deprived on the surface of the heat transfer coil 72, so that the circulating water flowing through the heat transfer coil 72 is cooled. Accordingly, the cooled circulating water is transferred to the latent heat evaporator 44 and the heat exchanger 74 of the air conditioner 42.
Circulating between the air conditioner 42 and the cooler 4
Since it is possible to reduce the load on the refrigerator 51 serving as the cold heat generating means of 2B, the same effect as in the first embodiment can be obtained.

However, the present invention is not limited to this, and the air may be blown out from the floor or the like. . In addition, the evaporative latent heat exchanger 44
Although the water 68 sprayed from the spray nozzle 44D of the water supply pipe 44E is circulated by the pump 44F, tap water may be supplied directly from the water supply to the water supply pipe 44E. It is particularly effective when the temperature of tap water in winter is low. In this case, since power for driving the pump 44F is not required, power consumption can be further reduced. In addition, the evaporative latent heat exchanger 44
The surface of the plate 44C or the surface of the heat transfer coil 72 is wetted with the water 68 sprayed from the jet nozzle 44D, but is evaporated by using a material such as a film or a ceramic so as to gradually exude water to the outside. You may. In the third embodiment, the radiation panel 84 is provided on the ceiling surface.
There is no particular limitation on the installation location as long as it is inside.

ができる。As described above, according to the air conditioning system of the present invention, the heat exchange means utilizing the latent heat of vaporization of the liquid is provided in the exhaust path for discharging return air out of the system. Thus, the cold heat obtained when the liquid is evaporated into the return air is used as all or a part of the cold heat source for air-conditioning the air-conditioning zone. Thereby, cold heat is obtained by using the return air that has been conventionally discarded, and this cold heat can be used as all or a part of a cold heat source for air-conditioning the air-conditioning zone. Therefore, the load on the cold heat source of the air conditioner can be reduced, so that energy saving air conditioning can be performed. In particular, since the heat exchange means using the latent heat of vaporization of the liquid is used, it is possible to obtain cold heat using as little electric power as possible. Thus, it is possible to provide a power-saving type air-conditioning system in which the power consumption of the cold heat generating means provided in the air conditioner is reduced.
