Description

An air purification module and an air conditioner

technical field

The invention relates to the technical field of air conditioners, in particular to an air purification module and an air conditioner.

Background technique

As air purification is paid more and more attention by people, more and more air conditioners have the function of sterilization and purification. Nano-water ion technology refers to nano-scale electrostatic atomized water particles. This technology is to discharge the water droplets on the tip electrode at high voltage to gradually split them into water mist and decompose them into highly active nano-scale water ions, which contain a large number of Highly active hydroxyl radicals, hydroxyl radicals have extremely high oxidative properties, and can decompose and remove bacteria, microorganisms, formaldehyde, VOC and other components in the air.

At present, there is a carbon fiber water-absorbing conductive electrode on the market, which is loaded with a water-absorbing factor to absorb water from the air, and then use high-voltage electricity to ionize it into nano-sized water ions and release it into the air to purify the air. However, this kind of carbon fiber electrode is made of carbon fiber bundles cured by a resin curing agent and produced under high-temperature carbonization conditions. It has high structural strength and is rich in microporous structures inside, which can then load water absorption factors to absorb water from the air.

At present, there are basically two electrical connection methods for this carbon fiber. One is to directly insert a metal needle into the carbon fiber electrode to supply power to it; the other is to fix and conduct electricity through a metal screw. One end of the metal screw is inserted into the carbon fiber electrode from the side. The other end crimps the high-voltage wire to the shell through the shell structure using a terminal. There are following deficiencies in the above two methods:

① Most of the water-absorbing factors currently used in the market, such as calcium chloride and gel, are mostly corrosive and will corrode metal pins or screws;

②Even if corrosion-resistant metal materials are used as metal pins or metal screws (such as titanium alloy, 317L, etc.), on the one hand, the cost is high, and on the other hand, because the carbon fiber electrode is connected to negative high-voltage electricity, under the energized condition The metal will lose electrons to form metal ions, and then electrochemical corrosion will occur, which will accelerate the corrosion of metal pins or screws;

③When the metal screw or metal needle is inserted into the carbon fiber electrode, the carbon fiber is easily broken and cracked due to high temperature carbonization, which will damage the shape of the electrode.

[Basic operating principle of air conditioner]

The air conditioner in the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle consists of a series of processes involving compression, condensation, expansion and evaporation to cool or heat an indoor space.

The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can realize the cooling effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner regulates the temperature of the interior space.

The outdoor unit of the air conditioner refers to a part of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner performs a heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner performs a cooling mode.

Among them, the conversion of the indoor heat exchanger and the outdoor heat exchanger into a condenser or an evaporator generally adopts a four-way valve. For details, refer to the settings of a conventional air conditioner, and will not be repeated here.

The refrigeration working principle of the air conditioner is: the compressor works so that the indoor heat exchanger (in the indoor unit, the evaporator at this time) is in an ultra-low pressure state, the liquid refrigerant in the indoor heat exchanger quickly evaporates and absorbs heat, and the indoor fan blows out After being cooled by the indoor heat exchanger coil, the air becomes cold air and is blown indoors. After the vaporized refrigerant is pressurized by the compressor, the high pressure in the outdoor heat exchanger (in the outdoor unit, it is the condenser at this time) It condenses into a liquid state in the environment, releases heat, and dissipates the heat into the atmosphere through the outdoor fan, so that the cycle achieves the cooling effect.

The heating working principle of the air conditioner is: the gaseous refrigerant is pressurized by the compressor to become a high-temperature and high-pressure gas, enters the indoor heat exchanger (in this case, the condenser), condenses and liquefies, releases heat, and becomes a liquid, and at the same time heats the indoor air, thereby To achieve the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (the evaporator at this time), evaporates and gasifies, absorbs heat, and becomes a gas. At the same time, it absorbs the heat of the outdoor air (the outdoor air becomes colder), and becomes a gaseous refrigerant. Enter the compressor again to start the next cycle.
