Abstract

PURPOSE:To reduce noise and vibration and lighten the air conditioner by providing Peltier effect element on the inner wall surface of a ventilation passage, and also providing a cooler which conducts heat exchange with heat radiating surfaces of Peltier effect elements on the water wall surface of the ventilating passage. CONSTITUTION:When an operating switch 21 is turned ON, respective modules 8a and motors 7 and 11 are operated, air flows on the indoor side as shown by arrows, and a heat absorbing operation and a heat radiating operation are carried out on both surfaces of each module 8a. When air is cooled on the heat absorbing surface side a condensed dew is produced on heat radiation fins 8a, and condensed dew slowly grows. The dew moves onto the side of a casing 6, and is collected in a water saucer 10. Water stored in the water saucer 10 circulates through a flowpath 9 by means of a drain pump 11 to cool the radiation surface of respective modules 8a. As a result, the heat radiation of modules 8a is promoted, and the cooling operation is promoted by this much, thus increasing the space cooling ability. Accordingly, a compressor, a coolant circulation circuit and the like become unnecessary, and therefore a quiet space cooling operation can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner that performs indoor air conditioning using a heat exchanger having a Peltier effect element as a module.

Conventional technology Conventionally, air conditioners mainly consist of a refrigeration cycle using 70 liters of refrigerant, and use the refrigeration vehicle to obtain cold air.
The room was being air-conditioned.

Problems to be Solved by the Invention However, the air conditioner with the above configuration produces noise such as vibrations and noise from the compressor and refrigerant circulation noise.
There are many sources of vibration, and there is a problem in that the structure must be complicated to counteract them.

In addition, this configuration requires connecting the compressor, condenser, pressure reducer, evaporator, etc. with piping to form a closed circulation circuit, which increases the weight and makes it difficult to reduce the weight. .

In view of the above problems, the present invention aims to reduce noise and vibration and reduce weight.

Means for Solving the Problems In order to solve the above problems, the present invention provides a Peltier effect element on the inner wall surface of the ventilation passage so that its heat absorption surface faces the inside of the ventilation passage, and A cooling device is provided on the outer wall surface to exchange heat with the heat radiation surface of the Peltier effect element.

Furthermore, the cooling device is a water supply passage provided on the outer wall surface of the ventilation passage.

By adopting such a configuration, it is possible to eliminate elements such as a compressor and refrigerant circulation, which are major causes of vibration and noise as in the past.

Further, by cooling the heat radiation surface of the Peltier effect element, a further cooling effect can be obtained.

Example Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

First, the configuration of the air conditioner will be explained with reference to FIG.

In Fig. 1, 1 is an air conditioner main body (hereinafter referred to as the main body) that is installed through the wall 2 of a house, and an inlet 3 and an outlet 4 are provided on the front side of the room. A wind circuit 5 that communicates the suction port 3 and the blowout port 4 is formed by a casing 6 . Reference numeral 7 denotes a fan provided in the iJ airflow circuit 5, which faces the air outlet 4. 8 is a heat exchanger located in the wind circuit 5 and attached to the casing 6, which includes a large number of heat exchange elements consisting of a module 8a that collects a large number of Peltier effect elements and a heat radiation fin 8b that increases the heat absorption area. It is configured by arranging. Further, the casing 6Fi is made of a heat conductor and has a tubular flow path 9 arranged in a meandering manner on the back surface.

Reference numeral 10 denotes a water tray provided at the lower part of the heat exchanger 8, which is attached to the Fuji casing 6 and is disposed across the inside of the wind circuit 5 and the outdoor side. Here, the radiation fins 8b are formed in a trapezoidal (or triangular) shape with a downwardly inclined lower end, so that the dew attached to the radiation fins 8b is guided to the casing 6 side and falls from the casing 6 into the water tray 10. is formed. Reference numeral 11 denotes a drain pump provided in the water pan 10, the outlet of which is connected to the flow path 9 of the casing 6, and a water supply circuit is configured such that water from the flow path 9 returns to the water pan 10 again. There is.

Next, a schematic electrical circuit of the air conditioner will be explained with reference to FIG. Components that are the same as those in FIG. 1 will be described using the same numbers.

In the figure, 20 is a DC power source, which is also converted from an AC power source if necessary. Reference numeral 21 denotes an operation switch, which connects the module 8a and the motor 7a of the fan 7.

The operation of the motor 11a of the drain pump 11 is controlled. Here, the modules 8a are connected in parallel with consideration given to their polarities so that the same surface (the surface on the wind circuit 5 side) performs a heat absorption function and the surface on the casing 6 side performs a heat dissipation function.

In the above configuration, when the operation switch 21 is turned on, each module 8a and motors 7a and 11a are respectively operated. As a result, wind flows on the indoor side as shown by the arrows in FIG. 1, and both sides of each module 8a have a absorbing effect and a heat dissipating effect, respectively.

Here, the drain pump 11 may be operated after a certain amount of water has accumulated. In addition, each motor 721
- 11a may be operated by AC power supply.

Then, as time passes and the heat absorption and heat radiation effects of each module 8a progress, dew condensation occurs on the heat radiation fins 8b on the heat absorption surface side when the air is cooled, and gradually grows. The water then moves toward the casing 6 by its own weight and is collected along the casing 6 into the water tray 10. Of course, indoor cooling continues at the same time.

The water collected in the water tray 10 is circulated through the flow path 9 by the drain pump 11 to cool the heat radiation surface of each module 8a. As a result, the heat dissipation of the module 8a is promoted, and the cooling action is also promoted accordingly, further increasing the cooling capacity.

This eliminates the need for compressors, refrigerant circulation circuits, etc., which were major sources of noise and vibration when cooling indoor rooms.
Achieves quiet cooling operation.

Furthermore, when the cooling capacity is increased, drain water having cooling energy is provided to the heat dissipation function of the module 8a, so that exhaust heat can be recovered and the number of juveniles can be improved.

Furthermore, when setting the cooling capacity, it can be adjusted based on the capacity of the module 8a alone or the number of modules used, and there is no need for multiple cooling capacity calculations as in the past.

Next, an embodiment of the pond of the present invention will be described with reference to FIG. Here, the same parts as in the previous embodiment are given the same numbers and the description thereof will be omitted.

In the figure, the difference from the previous embodiment is that the module 8
This is the cooling structure for the heat dissipation surface of a.

That is, in the previous embodiment, the heat dissipation effect of the module 8a was performed by both the air outside the room and the drain water.
Such a configuration has poor rise characteristics until drain water is obtained.

Therefore, in this embodiment, a cooling medium circulation circuit is separately provided.

In FIG. 3, 31 is a heat exchange section provided in contact with the heat radiating surface of the module 8a, 32 is a heat radiating section for cooling a medium (for example, water) sealed in the circulation circuit, and 33 is a heat radiating section inside the circulation circuit. This is a circulation pump for circulating the medium from the heat exchange section 31 to the heat radiation section 32.

With this configuration, from the time the air conditioner starts operating, the module 8a promotes heat exchange between its heat radiation surface and the heat exchange part 31, increases the cooling effect in a short time, and improves the start-up characteristics. It is measured.

In both of the above embodiments, the case of an air conditioner has been described, but it goes without saying that a heating effect can be obtained by reversing the direction of electricity supply to the module 8a.

Effects of the Invention As described above, the present invention allows indoor air conditioning to be performed using the cooling or heat dissipation effect of the Peltier effect element, thereby eliminating the need for a compressor and refrigerant distribution circuit, which are major sources of noise and vibration as in the past. Therefore, a quiet air conditioning effect can be obtained, and there is no need to provide vibration-proofing, sound-proofing materials, etc., and the configuration can be simplified. Furthermore, by eliminating the compressor, the weight can be reduced. Furthermore, by exchanging heat between the heat dissipation surface of the Peltier effect element and the cooling device, the heat absorption effect is promoted and the performance is improved.

Furthermore, by using the cooling device as a water supply passage provided on the outer wall surface of the ventilation passage, the cooling device and the Peltier effect element can be integrated into a unit, and further miniaturization can be achieved.
