Abstract

PURPOSE:To make it possible to carry out air-conditioning up to a comfortable region without obtaining other cooling power in a zone having a low humidity and a high temperature by disposing humidifiers in a supply side air passage and an exhaust side air passage respectively, and disposing a sensible heat exchanger across both passages. CONSTITUTION:The humidifiers 1 and 2 comprise lower water tanks 15 and 15', water spraying nozzles 16 and 16', circulating pumps 17 and 17', and automatic water suppliers 18 and 18' with water level adjusting valves, and humidify and cool the room by spraying water with respect to the air current within the passage. A sensible heat exchanger 3 is constituted by a heat pipe group and the like, and passes hermetically through a partition plate 5 and a number of heat pipes and the like are installed so that one end of the group is brought into contact with air in the passage A and another end thereof with air in the passage B. By this arrangement, only sensible heats in air in both passages A and B are heat-exchanged. A suction port 6 of the passage A is connected to an external air intake port 19, an exhaust port 7 to a blow- off port 20 of the room R requiring air conditioning, a suction port 10 of the passage B to a suction port 21 of the room R, and an exhaust port 11 to an exhaust port 22. High temperature dry air is subjected to sensible heat exchange with air cooled and humidified on the exhaust side in the humidifier 2, and is cooled. Thereafter, high temperature dry air is further cooled and humidified in the humidifier 1 and enters the room R as a desired conditioned air.

Description

[Detailed description of the invention] The present invention relates to an air conditioner for high temperature and dry areas.

In general, air conditioners that completely cool high-temperature outside air include heat pump systems that use compression refrigerators and absorption refrigerators, and heat-driven systems that use full dehumidifiers (the so-called Dunkle system). Cooling power was required.

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

In the air conditioner of the present invention, as shown in the drawings, humidifiers 1.2 are arranged 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 It has a configuration in which a sensible heat exchanger 6 for transferring heat to the air exiting the humidifying device 2 of all the sensible heat passages B is arranged across the inner passage A and the BVC. This device allows air conditioning in areas with low humidity and high temperatures without requiring any other cooling power and with a comfortable reduction in size.

To explain the details of the embodiment shown in the drawings, in Fig. 1, one casing 4 is divided into two airflow passages A and B IC by a partition plate 5vc, and the airflow passage Avc is divided from the suction port 6 toward the discharge lower. , a sensible heat exchanger 6, a humidifier 1, an eliminator 8, and a blower 9 are arranged, and the passage BVC, if any, extends from the suction port 10 to the discharge port 11, the humidification device 2,
An example of a structure in which an eliminator 12 and a sensible heat exchanger are arranged is shown.

The air waso system is used for the humidifier installed in both passages A and B, which includes a lower water tank 15.15', a watering nozzle 16.16', a circulation pump 17.17', and an automatic water supply system with a water level control valve. 18 and 18'Q), all of which humidify and cool the air R in the passage by spraying water with it. 1, the sensible heat exchanger 3 is composed of a group of heat pipes, etc., which pass through the partition plate 5 airtight so that one end is in contact with the air in passage A and the other end is in contact with the air in passage B. It is fully equipped with many heat vibrators. As a result, only sensible heat is exchanged between the air in both passages A and B.

The air thus configured is connected to the air inlet 6 to the passage B to the outside air intake 19, the discharge lower of the casing to the air outlet 20VC of the room R that requires air conditioning, and the air inlet 10 of the passage B Connect the exhaust port 22vc to the suction port 21, and the exhaust port 22vc.
When the blower 9.13 and circulation pump 17.17' are fully operated, suitable air conditioning can be achieved in the high temperature and dry region (V).

To give an example, absolute humidity IJj 0.006 kg/I
<9. When outside air with a dry bulb temperature of 30 to 40 C is taken into passage A, the absolute humidity in sensible heat exchanger B is 0.006 k
g79, the air becomes air with a dry bulb temperature of 25 to 27 C, and is cooled and humidified by water evaporation in the humidifier 1 at Vl, for example, absolute humidity 0.010 to o, ollkg, A+<g, dry bulb temperature 15 ~ i6p air is conditioned and blown into room R. On the other hand, air with a dry bulb temperature of 25C8 degrees and an absolute humidity of 0010 to 0.012 kglkg enters the passage Etc from room R, and is further humidified and cooled in the humidifier 2.
The absolute humidity is 0016 to 0.014 kglkg, and the dry bulb temperature is about 19 to 20C. This air fulfills the role of lowering the outside air of 60 to 40 C by 25 to 27 Cvc in the sensible heat exchanger 3.

The above numerical values 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 cooled and humidified in the humidifying bag @1 to produce the desired conditioned air. It can be extracted as

In other words, 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 several people's outside air before being humidified and cooled by the humidifying device 1. It is characterized by the fact that it is capable of cooling and humidifying low-humidity, high-temperature air without using cooling power like a Dunkle thermal drive device that uses a refrigerator or dehumidifier.
This is particularly advantageous because air conditioning can be performed at low cost and in an energy-saving manner. Although the illustrated embodiment shows an example in which the passage A is placed on the lower level and the passage B is placed on the upper level, this may be done upside down, or the same effect can be obtained by arranging the cases side by side in the horizontal direction. Of course.
