Description

TECHNICAL FIELD [0001] The present invention relates to a thermoelectric power generator for an air conditioner,

The present invention relates to a thermoelectric generator for an air conditioner that generates electric energy by using waste heat generated from an air conditioner.

In general, refrigeration technology is a refrigerant which is refrigerated by evaporation heat caused by repetition of compression and expansion, and a vapor compression refrigerator is mainly used. Recently, absorption refrigerator has been widely used in order to keep pace with energy saving trend. In addition to the general refrigeration technology, refrigeration technology using a special method has been developed and applied in domestic and foreign countries with the recent development of high-tech industry, and its range is gradually expanding.

Recently, the importance of the refrigeration and air conditioning industry as a necessity of modern living and advanced industrial technology environment which has been expanded to various industrial environments through high performance, miniaturization, energy saving, low noise and environmentally friendly technology development is increasing Demand for indoor environment that requires highly clean conditions such as the rapid development of building facilities due to the emergence of intelligent buildings due to office automation, bio-technology related facilities due to the production process of advanced electronic semiconductor industry and genetic engineering development In the field of automobiles, it is urgently required to provide high performance, high efficiency and low noise freezing air conditioning.

A refrigeration cycle refers to a cycle in which a refrigerating operation takes place during the process of returning to the initial state. In the refrigerating machine, the refrigerant passes through the expansion valve and enters the evaporator after being reduced in pressure. In the evaporator, the liquid refrigerant evaporates due to latent heat of evaporation. Then, the evaporated refrigerant vapor receives the work from the outside, that is, the compressor, and compresses the refrigerant vapor to make high temperature and high pressure. Pressurized high pressure steam is sent to the condenser where it emits and condenses condensation heat. The condensate again forms a cycle into the expansion valve. The refrigerant continuously circulates in the refrigerating apparatus continuously or in a gas state.

The refrigeration cycle consists of compression, condensation, expansion, and evaporation. There are four main components of the refrigeration cycle: ① compressor, ② condenser, ③ expansion valve, and ④ evaporator. It can be said that it is equipped with an electronic controller to connect with piping (copper pipe) and to fill the inside with refrigerant and to smoothly control the flow thereof.

However, in the conventional refrigeration cycle as described above, waste heat is generated when the refrigerant undergoes a phase change from a high-temperature and high-pressure liquid state to a low-temperature and low-pressure gas state. However, since the waste heat is dissipated without being reused, There is a problem that can not be done.

To solve these problems, a power generation apparatus using a refrigeration cycle of a refrigerator has been disclosed in Korean Patent No. 10-0756879. The power generating device using the refrigeration cycle of the refrigerator includes a first energizing member whose one end is in contact with the evaporator of the refrigerator and the other end is in contact with the outlet of the compressor of the refrigerator, A second energizing member constituting a closed circuit, and a storage battery connected to a connection point of the first energizing member and the second energizing member and storing a heat current generated in the closed circuit.

However, since the length of the first energizing member and the second energizing member are considerably long, there is a problem that the power generation efficiency is considerably lowered in the power generating apparatus using the refrigeration cycle of the refrigerator.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a cooling apparatus for a refrigerator, in which a first thermoelectric generator is formed between a condenser and air (or a cooling portion) inside an outdoor unit, and a second thermoelectric generator is provided between the evaporator and indoor air An object of the present invention is to provide a thermoelectric generator for an air conditioner in which not only the structure of the apparatus becomes very simple but also the manufacturing cost is low and the thermoelectric performance is improved.

According to an aspect of the present invention, there is provided a thermoelectric generator for an air conditioner, comprising: a compressor for compressing a refrigerant; a condenser for condensing the compressed refrigerant; an expansion valve for expanding the condensed refrigerant; A first thermoelectric generator having the condenser as a high temperature section and the air inside the outdoor unit provided with the condenser as a low temperature section; And a second thermoelectric generator having the evaporator as a low temperature portion and the room air exchanging heat with the evaporator as a high temperature portion.

The air conditioner further includes a compressor for compressing the refrigerant, a condenser for condensing the compressed refrigerant, an expansion valve for expanding the condensed refrigerant, and an evaporator for evaporating the expanded refrigerant, wherein one surface is in contact with the condenser A first thermoelectric generator contacting the cooling part whose other surface is a low temperature part; And a second thermoelectric generating element which is in contact with the evaporator whose other surface is a low temperature portion and which is in contact with a heat source portion whose one surface is a high temperature portion and the fluid of the cooling portion circulates to the cooling portion again via a heat radiating portion by a pump, The fluid in the heat source unit is circulated to the heat source unit again by the pump through the heat absorbing unit and the heat absorbing unit can be heated by the blowing fan installed inside the indoor unit.

A heat insulating ring may be formed on the rim of the first thermoelectric generator or the second thermoelectric generator.

The present invention has the effect of significantly reducing the power consumption of the air conditioner because the configuration of the apparatus is very simple and the manufacturing cost is considerably reduced and the current generated in the first and second thermoelectric devices can be used.

Further, by forming the heat insulating ring at the rims of the first and second thermoelectric power generators, the temperature difference between both surfaces of the thermoelectric power generator can be uniformly increased to improve the thermoelectric performance.

On the other hand, when the air conditioner enters the steady state, the noise level generated according to the cycle of the refrigeration cycle will vary according to the cycle, so that the noise input unit is formed in the outdoor unit and / or the indoor unit, By detecting the magnitude and phase according to the frequency and generating a sound having opposite phases of magnitude corresponding to the noise, the noise can be significantly reduced by the canceling action of the two notes. At this time, a microphone may be used as the noise input unit, and a sound having a phase opposite in magnitude corresponding to the noise may be output through the speaker.
