Description
Technical Field
The invention relates to an air conditioning device, in particular to a portable air conditioner based on a semiconductor refrigerating sheet.
Background
Including central air conditioning system and domestic air conditioner among the current air conditioning equipment, generally adopt compressor and freon or other refrigerants to refrigerate, its structure is complicated, power consumption is big, can only fix a point the installation, and installation and dismantlement are very inconvenient, and freon's use destroys greatly to environmental pollution, is unfavorable for the environmental protection. Both central air conditioning systems and domestic air conditioners cool or heat entire rooms or entire buildings with high energy consumption, while local cooling/heating systems (LCHS) can reduce the energy demand for cooling/heating, and they only regulate the ambient temperature around the user's body, not the ambient temperature of the whole building, so they are favored and advocated by many people in regions that are not particularly cold or hot, on the premise that the comfort of the user feeling the temperature is not lost.
In addition, in hot summer, heat stroke can result; in cold winter, low-temperature symptoms can be caused, people who need to be in the outdoor environment for a long time have absolute requirements on regulating body temperature comfort level, the adoption of the existing air conditioner inevitably causes great waste, the existing air conditioner needs to be installed in a fixed place, has high power consumption, overlarge volume and overlarge weight and is not suitable for being used in the outdoor environment, and as for the adoption of a fan for cooling, only air is blown to flow, the cooling effect is very limited, and when the temperature is very high, the cooling effect of the fan is very little; when the temperature is low, it is not useful. The portable water cooling fans and portable atomizing fans that have appeared in the current day buildings claim to reduce the temperature to 6 to 8 degrees. The principle of the water cooling fan is that a water pumping motor or a water absorbing material is utilized, and water is distributed on a filter material through the internal structure design to form a water curtain. When air is sucked into the water cooling fan, the air is subjected to heat exchange through the water curtain, so that the temperature of the air is reduced, the humidity of the air is increased, and the processed air is blown out by the fan. When the treated air is blown to the surface of the skin, partial heat on the surface of the skin can be taken away by high-humidity cool wind, and people feel that the temperature is reduced. The principle of the portable spray fan is similar, but the spray evaporation cooling technology is used instead, heat exchange is carried out on small water points of air through evaporation, heat is absorbed, and the treated air is blown out. However, through practical tests, the product can blow cool air which is about 2 to 5 degrees lower than the room temperature under the environment that the temperature is lower than 28 ℃ and the relative humidity is lower than 60 percent. In high temperature and high humidity environment, the product has no utility. There is a great need for a portable air conditioning device for outdoor environments or some indoor spaces where no air conditioner is installed.
At present, a semiconductor refrigerating wafer capable of heating and refrigerating appears, and the principle is that when an N-type semiconductor material and a P-type semiconductor material are connected into a galvanic couple pair, energy transfer can be generated by electrifying direct current, the current can absorb heat from a joint flowing from the N-type to the P-type to become a cold end, and if the heat is released from the joint flowing from the P-type to the N-type, the current becomes a hot end. If the current direction is reversed, the cold and hot ends are switched. The size of the absorbed heat and the released heat is determined by the current, and the characteristic of the thermoelectric refrigerating device and the high-efficiency heat exchange system can be applied to portable air-conditioning equipment. Patent CN103423814A discloses a portable air conditioning device, which includes a semiconductor cooling sheet, two leads of the semiconductor cooling sheet are respectively connected with the positive pole and the negative pole of a power supply; the two sides of the semiconductor refrigerating sheet are respectively provided with a heat absorbing sheet and a heat radiating sheet, the upper surface of the semiconductor refrigerating sheet is provided with a mask, and the mask is provided with a tying belt. Heat-conducting silicone grease is filled between the semiconductor refrigerating sheet and the heat absorbing sheet and between the semiconductor refrigerating sheet and the heat radiating sheet, and the face mask is provided with ventilation holes. Patent CN203810612U discloses a small semiconductor air conditioner, which comprises an electric cabinet, an air inlet, a fan, a semiconductor chip, and heat exchangers and air outlets located on two sides of the semiconductor chip from bottom to top in sequence. The air conditioner is a desktop cabinet type small semiconductor air conditioner, and utilizes a semiconductor chip to refrigerate and provide cold air, and adopts a heat storage agent to suck away the hot air. Patent CN2198546Y discloses a cooling and heating device using peltier elements, which is a heat shield equipped with peltier elements, the cooling and heating surfaces of which are respectively disposed on two sides of the heat shield, the heating surface is equipped with a radiator, the cooling surface is equipped with an energy storage diffuser and is externally equipped with a shielding case, one end of the shielding case is an air inlet, the other end is equipped with a ventilator and an air outlet, and the peltier elements are connected with a reversing switch and are connected with a direct current power supply. However, in the technical solutions of the above three patents, because of the defects of cold-end ventilation and heat exchanger design or poor heat dissipation system design, the semiconductor refrigeration sheets with the same power are used, and the air can only be cooled to about 3-4 ℃ at low efficiency, if the semiconductor refrigeration sheets with higher power are replaced, the power consumption is greatly increased, and the semiconductor refrigeration sheets are inconvenient to carry and use outdoors, so that the actual use requirements cannot be met, and no product with similar purposes appears in the market.
Therefore, it is the initiative of the present invention to provide a portable air conditioner based on semiconductor cooling sheet, which has reasonable structure design, can be used easily at any time and place, can be carried about, has light weight, low noise, simple manufacture and low cost, and can effectively regulate the air temperature.
