Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner for high temperature and dry areas.

Generally speaking, air conditioners that cool high-temperature outside air are
Heat-pump systems using compression refrigerators and absorption refrigerators, and heat-driven systems using dehumidifiers (the so-called Dunkle system) have been used, but both require cooling power.

An object of the present invention is to provide an air conditioner for high-temperature dry air that does not require such cooling power.

As shown in the drawings, the air conditioner of the present invention has humidifiers 1 and 2 disposed in the air supply side air passage A and the exhaust side air passage B, so that the air before entering the humidifier 1 in the passage A is The retained sensible heat is transferred to the humidifier 2 in passage B.
It has a configuration in which a sensible heat exchanger 3 for transferring heat to the air exiting the air is placed across both passages A and B.
This device allows air conditioning to a comfortable level in areas with low humidity and high temperatures without requiring any other cooling power.

To explain the details of the embodiments in the drawings, the first
In the figure, the inside of one casing 4 is divided into two parts by a partition plate 5.
It is divided into two airflow passages A and B, and in the case of passage A, the sensible heat exchanger 3, humidifier 1, eliminator 8, and blower 9 are arranged from the suction port 6 to the discharge port 7, and the passage B In this case, from the suction port 10 to the discharge port 11, the humidifier 2 and the eliminator 1 are installed.
2. An example of a structure in which a sensible heat exchanger is installed is shown.

The humidifiers installed in both passages A and B use an air washer system, and the lower water tanks 15 and 1
5', water nozzle 16, 16', circulation pump 17,
17' and an automatic water supply device 18, 18' with a water level control valve, both of which humidify and cool the air flow in the passage by spraying water. The sensible heat exchanger 3 is composed of a group of heat pipes, etc., and passes through the partition plate 5 airtight so that one end is in contact with the air in the passage A and the other end is in contact with the air in the passage B. A large number of heat pumps, etc. are installed in the building. As a result, only sensible heat is exchanged between the air in both passages A and B.

The air configured in this way is passed through the suction port 6 of passage A.
is connected to the outside air intake port 19, the discharge port 7 is connected to the air outlet 20 of the room R that requires air conditioning, the suction port 10 of the passage B is connected to the suction port 21 of the room R, and the discharge port 11 is connected to the exhaust port 22 By connecting the air blowers 9 and 13 and the circulation pumps 17 and 17' to the air blowers 9 and 13, suitable air conditioning can be achieved in hot and dry regions.

To give one example, when outside air with an absolute humidity of 0.006 Kg/Kg and a dry bulb temperature of 30 to 40°C is taken into passage A, the absolute humidity of the sensible heat exchanger 3 is 0.006 Kg/Kg and a dry bulb temperature of 25 to 27°C. The air is cooled and humidified by evaporation of water in the humidifier 1, and is blown into the room R after being conditioned to have an absolute humidity of 0.010 to 0.011 Kg/Kg and a dry bulb temperature of 15 to 16°C, for example. On the other hand, from room R, for example, the dry bulb temperature is about 25℃ and the absolute humidity is 0.010.
~0.012Kg/Kg of air enters passage B, is further humidified and cooled in humidifier 2, and has an absolute humidity of 0.013
~0.014Kg/Kg, dry bulb temperature around 19-20℃.
This air plays the role of lowering the outside air of 30 to 40°C to 25 to 27°C in the sensible heat exchanger 3.

The above figures are just an example, and the high temperature dry air is cooled by exchanging sensible heat with the cooled and humidified air in the humidifier 2 on the exhaust side, and then further cooled and humidified in the humidifier 1 and taken out as the desired conditioned air. be able to. That is, in the device of the present invention, a humidifying device 2 is also installed on the exhaust side, and the air that has passed through the humidifying device 2 is cooled by exchanging only the sensible heat of the taken outside air before being humidified and cooled by the humidifying device 1. It is characterized by the fact that
It is very useful because it can cool and humidify low-humidity, high-temperature air, and air conditioning can be performed at low cost and in an energy-saving manner. In the illustrated embodiment, the passage A is placed on the lower level and the passage B is placed on the upper level, but this may be done upside down, or the same effect can of course be obtained by arranging them horizontally next to each other. It is.
