Description

The semiconductor residential central air conditioning
Technical field
The utility model relates to a kind of residential central air conditioning, particularly a kind of compressor-free, the semiconductor residential central air conditioning of employing thermoelectric cooling technology.
Background technology
Residential central air conditioning, be known as by people is outstanding person in the domestic air conditioning always, and it is not there to be indoor on-hook, and ventilation volume is big, do not take the useful space, temperature equalization can be freezed, and can heat again, promptly be life product, be ornament again, attractive in appearance, plurality of advantages such as be suitable for and be subjected to people's welcome deeply.But the residential central air conditioning that international, domestic at present institute produces, uses, also exist many weak points technically, it mainly shows as: 1, owing to adopting compressor cooling, heating, the cooling agent that is adopted has been the fluorine medium, seriously polluted the indoor and outdoor environment, and even the environment of human survival has formed a kind of new public hazards.2, the indoor and outdoor noise is very big, has produced new pollution sources again.3, sale price is too high, and expense is too big, and client affords but with not rising, and power consumption is surprising.
Thermoelectric cooling also claims semiconductor refrigerating (Semi-Conductor Cooling Device), thermoelectric refrigerator, electronic cooling etc.The French scientist Peltier had been found metal thermoelectric back wash effect in 1834.Promptly a pair of thermocouple of being made up of two kinds of different metals when electric current passes through thermocouple, because of the direction difference of direct current feeding, will produce the neither endothermic nor exothermic phenomenon at the thermocouple junction place, and this sharp physical phenomenon is called Peltier effect.Semiconductor cooler is the characteristics according to the pyroelectric effect technology, adopt the particular semiconductor material thermoelectric pile to freeze, electric energy directly can be converted to heat energy, the efficient height, it is a kind of new green environment protection high-tech product, pollution-free, noiseless, cold, the heat conversion is quick, work is world-famous for rapidly, the refrigeration of being favored always by people, one of best-of-breed technology that heats in recent years, because the continuous development of science and technology, along with the thermoelectric cooling technic of the continuous development of domestic and international electronics industry and semi-conductor industry is used more and more wider, use power is increasing, remove at original several high-tech, outside use in the national defence field, in household appliance technical field, also progressively begin to use and popularize, as cooling-water machine, refrigerating box, refrigerator (wine cabinet), refrigerator cabinet and small-power air-conditioning etc.Because the thermoelectric cooling technology is better than traditional mechanochemistry refrigeration aspect a lot, be subjected to very much people's favor since the appearance always.
But adopt the thermoelectric cooling technology to be applied to the air-conditioning aspect at present, can only produce some small-powers, the air-conditioner of direct-cooling type, as publication number is CN2537940 Chinese patent disclosed " electric refrigerating and heating economic benefits and social benefits air-conditioner ", comprise the working air current passage, the cooling and warming device, the radiating airflow passage, the cooling and warming device is that the semiconductor refrigerating that is positioned at the connection power supply of radiator heats device, through radiator, the working air current passage carries out heat exchange, and control semiconductor refrigerating by the flow direction of electric current in the control semiconductor, heat the conversion of face, air is freezed or heats.Be CN2463728 Chinese patent disclosed " cabinet type single indoor set semiconductor air conditioner device " also as publication number, include housing and electrical control gear, housing is cabinet type housing, and inner chamber has cold chamber and hot chamber, there is air inlet/outlet to be communicated with indoor and outdoors respectively, and is respectively equipped with blower fan; Settle the semiconductor refrigerating plate between cold chamber and hot chamber, the cold junction of semiconductor refrigerating plate is connected with fin heat transfer in being distributed in cold chamber, and the hot junction is connected with fin heat transfer in being distributed in hot chamber.From the air-conditioning of above-mentioned two kinds of structures as can be seen, adopting the direct-cooling type structure is exactly to utilize blower fan to force to heat device by semiconductor refrigerating needs refrigeration or the room air that heats to carry out heat exchange.Such frame mode is feasible to low power air-conditioning, but also exists the bigger shortcoming of fan noise, and is just less qualified to do it to residential central air conditioning.
Summary of the invention
