Description

Air purification module and 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

With the increasing attention paid to air purification, more and more air conditioners have the function of sterilization and purification. The nanometer water ion technology is nanometer electrostatic atomized water particle, and includes high voltage discharge of water drop on the tip electrode to split the water drop into water mist and decomposed into nanometer water ion with high activity, which contains great amount of hydroxyl radical with high activity and high oxidizing property to decompose and eliminate bacteria, microbe, formaldehyde, VOC and other components in air.

At present, a carbon fiber water absorption conductive electrode is available in the market, water absorption factors are loaded in the carbon fiber water absorption conductive electrode, water is absorbed from air, and then the carbon fiber water absorption conductive electrode is ionized into nanometer water ions by high voltage and then released into the air to purify the air. However, the carbon fiber electrode is formed by curing carbon fiber bundles by a resin curing agent and carbonizing the carbon fiber bundles at a high temperature, has high structural strength, is rich in a microporous structure inside, and can further load a water absorption factor to absorb water into the air.

At present, the electrical connection method of the carbon fiber is basically divided into two methods, one is that a metal needle is directly inserted into the carbon fiber electrode to supply power to the carbon fiber electrode; the other type is fixed and conductive through a metal screw, one end of the metal screw is inserted into the carbon fiber electrode from the side, and the other end of the metal screw enables the high-voltage wire to be in compression joint with the shell through the shell structure by using a connecting terminal. The above two methods have the following disadvantages:

(1) most of water absorption factors used in the market at present, such as calcium chloride, gel and the like, are corrosive and can corrode metal needles or screws;

(2) even if a corrosion-resistant metal material is used as a metal needle or a metal screw (such as titanium alloy, 317L and the like), on one hand, the cost is high, and on the other hand, because the carbon fiber electrode is switched on by negative high-voltage electricity, the metal can lose electrons under the electrified condition to form metal ions, so that electrochemical corrosion is generated, and the corrosion of the metal needle or the screw is accelerated;

(3) when the metal screw or the metal needle is inserted into the carbon fiber electrode, the carbon fiber is easy to break and crack due to high-temperature carbonization, and the shape of the electrode is damaged.

[ basic operation principle of air conditioner ]

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

The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. 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 ambient 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 achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

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

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger functions 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.

The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein any more.

The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air to be blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.

The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at this time), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, thereby achieving the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at this time), is evaporated, gasified and absorbs heat to form gas, absorbs heat of outdoor air (the outdoor air becomes cooler), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.
