[ 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 cool 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 heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state 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 an expansion valve may be provided in 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 serves 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 again.

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, at the moment, the evaporator) 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 through 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, at the moment, the condenser) to release heat, the heat is dissipated into the atmosphere through the outdoor fan, and the refrigeration effect is achieved through 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 the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.

The emitter electrode 300 uses a carbon fiber rod sintered at a high temperature as a base material, and is filled with a high-efficiency water absorption factor, such as calcium chloride, water absorption gel and other materials.

The specific manufacturing process comprises the following steps: firstly, selecting a bundle of carbon fibers, wherein the number of the carbon fibers can be selected according to the diameter of a required electrode, and the number of the carbon fibers after being stranded is the number of the carbon fibers after being stranded, and the purpose of yarn shaking is to uniformly disperse the stranded fibers and prevent the fibers from being entangled; then mixing the carbon fiber bundle with an epoxy resin curing agent, putting the carbon fiber bundle into a shaping hot box after mixing, bonding the surfaces of the carbon fibers together under the action of heat, wherein the shaped bar stock has a regular geometric shape; putting the shaped bar into a high-temperature furnace, carbonizing under the protection of inert gas, soaking the carbonized bar in dilute hydrochloric acid for 2 hours, then putting the bar into distilled water, ultrasonically cleaning for 10min, taking out the bar, and putting the bar into a blast drying oven for drying; after drying, performing surface treatment by using low-temperature plasma, and generating hydrophilic groups such as hydroxyl radicals on the surface of the carbon fiber rod after the treatment is finished; and processing the modified carbon fiber bar according to the size.

After the processing is finished, putting the processed carbon fiber electrode into distilled water for ultrasonic cleaning for 10min, removing scraps and surface oil stains generated in the processing process, then putting the carbon fiber electrode into a blast drying box for drying for later use, then putting anhydrous calcium chloride solid particles and distilled water into a beaker to prepare a saturated calcium chloride solution, putting the processed carbon fiber electrode into the saturated calcium chloride solution, then putting the saturated calcium chloride solution into an ultrasonic cleaning machine for ultrasonic infiltration for 10min, so that the saturated calcium chloride solution can be fully infiltrated into the carbon fiber electrode, taking out the carbon fiber electrode rod fully infiltrated with the saturated calcium chloride solution, putting the carbon fiber electrode rod into a high-temperature drying box, drying moisture in the saturated calcium chloride solution, and enabling the calcium chloride particles to be adsorbed inside the carbon fiber electrode; and (5) vacuum packaging the dried electrode for later use.

The skeleton of the emitter electrode 300 is carbon fiber, and the carbon fiber is cured and molded by a grease binder. The calcium chloride particles dried at high temperature are left in the carbon fiber water absorption electrode. In the practical use process, the carbon fiber particles absorb water from the air to be excited by high-voltage ionization, and the water absorption electrode has excellent water absorption performance.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
