Abstract

PURPOSE:To prevent moisture-rich cool air from circulating in a room by a structure wherein a carrying pipe of heat transfer medium such as brine or the line is connected in a loop so that the cryogenic heat produced at a heat source side heat exchanger by the evaporation of water is discharged at an availing side heat exchanger in the air conditioner directly utilizing the heat of vaporization of water. CONSTITUTION:The heat source side heat exchanger 1 and the availing side heat exchanger 2 are respectively arranged at the upper and lower parts of the air conditioner. Groups of a large number of parallel plate fins 5 and 6 are respectively arranged between end plates 3 and 4. Pipes 7 and 8, which are connected to each other so as to make a loop and within which brine is forcibly circulated, are arranged in zigzags in such a manner that the pipes 7 and 8 respectively pierce the end plates 3 and 4 and the groups of fins 5 and 6 at right angles. In addition, a water sprinkling pan 12 is seated through a water-moistened cloth 13 onto the upper part of the group of plate fins 5 and a water collecting pan 14 is connected through a pump 18 to a water tank 15 by means of a return pipe 19 in order to send back the water dropped down from the water sprinkling pan 12 into the water collecting pan 14. Owing to the structure as described above, the surfaces of the fins of the heat source side heat exchanger is wetted at all times with the water circulated as just mentioned above, which is forcibly evaporated by means of a fan 10 in order to cool the plate fins 5. On the other hand, because the cool air cooled at the heat exchanger 2 is forcibly ventilated by means of a fan 11, the agreeable conditioning in the room can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that performs air conditioning (cooling) using the heat of evaporation of water rather than frozen water.

This type of device that utilizes the heat of evaporation of water is, for example, called a simple cooling device, which circulates water through a wet cloth and evaporates the water by forcing air through the wet cloth. There are known devices that forcefully circulate the heat of evaporation indoors. However, this cooling device has the disadvantage that it circulates a large amount of air containing humidity into the room, causing discomfort to the user, and making it almost impossible to use it during periods of high humidity.

In view of the above, the present invention has been made to provide an air conditioner that can perform cooling without adding humidity, and one embodiment thereof will be described below with reference to the accompanying drawings.

FIG. 1 shows a developed perspective view of the inside of the air conditioner, in which 1 is a heat source side heat exchanger, and 2 is a user side heat exchanger, which are arranged in a side-by-side relationship. Both the heat source side heat exchanger 1 and the user side heat exchanger 2 have left and right end plates 3, 4, and this end plate 3,
It consists of a large number of plate-like fins 6.6 arranged in parallel between the fins 6.6, an end blend 3°4, and a pipe 7.8 extending orthogonally through the plate-like fins 6.6 and arranged in a meandering manner. . The inlet and outlet of these pipes 7.80 are communicated with each other and connected in a loop, and brine is sealed in the pipes 7.8, so that these pipes 7.8 constitute a heat medium transport pipe. Reference numeral 9 denotes a circulation pump interposed within the loop-shaped pipe 7.8, which forcibly circulates the brine.

10.11 is the heat source side heat exchanger 1. A heat source side fan and a user side fan are arranged to face the user side heat exchanger 2, respectively, and force air convection. Reference numeral 12 denotes a water sprinkler placed on the upper side of the heat source side heat exchanger 1 via a damp cloth 13 that contacts the ends of the plate-shaped fins 5, and is fixed by an end plate 3. 14 is a water collector arranged at the lower end of the heat source side heat exchanger 1. On the other hand, 16 is a water storage tank into which tap water is introduced through a water supply pipe 16 connected to a water supply or the like, and is controlled by a float pulp 17 so that a constant amount of water is always stored. The water collector 14 and the water storage tank 16 are connected by a return pipe 19 having a pump 18, which acts preferentially to appropriately return the water in the water collector 14 to the water storage tank 16. Supply is performed only when the water level in the water tank 15 decreases. The water in the water tank 15 is configured to be constantly supplied to the water sprinkler 12 through a water pipe 20 that opens to the water sprinkler 12, and the water in the water sprinkler 12 is distributed uniformly to each plate-shaped fin 5 by a wet cloth 13. It is structured so that it flows.

On the other hand, as shown in FIG. The discharge port 24 is installed to communicate with the conditioned air intake port 27 of the air-conditioned room 26 . Therefore, outdoor air is forcibly circulated through the heat source side heat exchanger 1, and outdoor air is taken into the usage side heat exchanger 2, subjected to heat exchange, and then discharged to the air-conditioned room 26.

That is, water is constantly circulated on the fin surface of the heat source side heat exchanger 1, and the fan 10 performs forced ventilation to forcefully evaporate the water, and the heat of evaporation causes the plate-shaped fins in a heat exchange relationship with the pipe 7 to 5 is cooled. Therefore, the brine circulating in the pipe 7 is also cooled and circulated to the utilization side heat exchanger 2. On the other hand, in the heat exchanger 2 on the user side, outdoor air is also forced into the heat exchanger 2 by forced ventilation by the fan 11.
The air is cooled down and introduced into the air-conditioned room 26.

The brine in the pipe 8 of the user-side heat exchanger 2 performs a circulating operation so that heat is removed and the brine returns to the pipe 7.

Therefore, comfortable cooling operation can be performed continuously without introducing cold air containing humidity into the air-conditioned room 26.

In the above embodiment, the brine was forcibly circulated through the pipe 7°8 by the circulation pump 9 as the heat medium transport pipe, but it is also possible to use a so-called heat pipe in which the refrigerant is sealed in a sealed pipe as the heat medium transport pipe. It's okay. In this case, there is an advantage that the circulation pump 9 can be omitted and a power source is not required, but the heat source side heat exchanger 1 must be placed at the top and the user side heat exchanger 2 must be placed at the bottom. It is not possible to arbitrarily set the vertical relationship or horizontal relationship compared to what is possible.

As is clear from the above description, according to the present invention, the evaporation of water is transferred to the heat exchanger on the user side using a heat medium transport pipe.
Since the air conditioner is designed to cool the room, it is possible to achieve comfortable air conditioning without having to circulate cold air containing humidity as in the conventional case.
