Detailed Description
In order to facilitate understanding of the invention, the invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the split air conditioner of the present invention includes an outdoor unit 100 and an indoor unit 200, wherein the outdoor unit 100 and the indoor unit 200 are communicated with each other through a blowing duct 300; the outdoor unit 100 is installed outdoors to change the temperature of fresh outdoor air, and then, the fresh outdoor air is supplied to the indoor unit 200 through the supply duct 300, and the indoor unit 200 is installed indoors to discharge the changed temperature fresh air into a room to adjust the indoor temperature. The outer surface of the air supply duct 300 is wrapped with a duct insulation layer 310, and the heat dissipation is prevented by the duct insulation layer 310, so that the temperature of the air in the air supply duct 300 is not changed.
The present invention sets the evaporator 120 installed in the indoor unit 200 of the conventional air conditioner into the outdoor unit 100, and directly changes the temperature of the sucked fresh air through the evaporator 120. As shown in fig. 1, a temperature varying box 110 is provided in an outdoor unit 100, an evaporator 120 is provided in the temperature varying box 110, an inlet end of the temperature varying box 110 is communicated with an air intake duct 180 of the outdoor unit 100, and an outlet end of the temperature varying box 110 is communicated with an air blowing duct 300. The outdoor unit 100 further includes a condenser 130 and a compressor 140, and the condenser 130 and the compressor 140 are disposed outside the temperature-variable box 110; the condenser 130 is communicated with the evaporator 120 through an expansion valve 150, and the compressor 140 is respectively communicated with the condenser 130 and the evaporator 120 through a four-way valve; the evaporator 120, the condenser 130 and the compressor 140 constitute a circulation temperature varying system inside the outdoor unit 100.
As shown in fig. 1, in order to ensure the circulation effect of the fresh outdoor air in the outdoor unit 100, a first suction fan 160 is disposed inside the inlet end of the temperature changing box 110, and a blowing fan 190 is disposed inside the outlet end of the temperature changing box 110; outdoor fresh air is sucked into the temperature-variable box 110 by the first suction fan 160, and the temperature-variable fresh air is sent into the blowing duct 300 by the blowing fan 190. A one-way dustproof air valve 170 is arranged between the air inlet channel 180 and the first air suction fan 160, and the fresh air sucked by the first air suction fan 160 is filtered through the one-way dustproof air valve 170 so as to filter dust in the fresh air and ensure the indoor air quality, and meanwhile, the one-way dustproof air valve 170 can also prevent the sucked fresh air from flowing reversely. The outer surface of the temperature changing box 110 is wrapped with a heat insulation layer 111, the temperature in the temperature changing box 110 is ensured by arranging the heat insulation layer 111, and the temperature changing effect is prevented from being influenced by heat loss; the outlet end of the temperature changing box 110 is further provided with a drain pipe 112, and accumulated water generated by condensation when the temperature of the fresh air is changed can be discharged from the drain pipe 112.
As shown in fig. 1, an air duct box 210 is arranged in an indoor unit 200 of the present invention, the air duct box 210 penetrates through the indoor unit 200, two ends of the air duct box 210 are respectively communicated with an inlet end and an outlet end of the indoor unit 200, and the inlet end of the indoor unit 200 is communicated with an air supply duct 300; the fresh air having undergone temperature change by the evaporator 120 in the outdoor unit 100 is delivered to the air duct box 210 through the air supply duct 300, and the air having undergone temperature change flows to the outlet end of the indoor unit 200 along the air duct box 210 and is discharged into the room. In order to improve the air circulation effect, the air guide fan 220 and the second air suction fan 230 are arranged in the air duct box 210, as shown in fig. 1, the air guide fan 220 is arranged at one end of the air duct box 210 communicated with the outlet end of the indoor unit 200, and the second air suction fan 230 is arranged at one end of the air duct box 210 communicated with the inlet end of the indoor unit 200; the second suction fan 230 sucks air in the supply duct 300 into the duct box 210, and the guide fan 220 guides the air in the duct box 210 to be discharged into the room. Further, a one-way air valve 240 is provided between the second suction fan 230 and the air supply duct 300, and the flow direction of air is restricted by the one-way air valve 240 to prevent the air having changed temperature from flowing back.
When the split air conditioner of the present invention operates, taking a refrigeration work as an example, after the air conditioner is set to have a refrigeration function through a remote control panel, the compressor 140 in the outdoor unit 100 starts to operate, the compressor 140 compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and then sends the gaseous refrigerant into the condenser 130 for cooling, the refrigerant is cooled in the condenser 130 and then becomes a medium-temperature high-pressure liquid refrigerant, the liquid refrigerant is throttled and depressurized by the expansion valve 150 and then becomes a low-temperature low-pressure gas-liquid mixture, the gas-liquid mixture is sent to the evaporator 120, the evaporator 120 absorbs heat in the gas-liquid mixture and then is vaporized into a gaseous state again, and the gaseous refrigerant is sent back to the compressor 140 again for compression. When the compressor 140 operates, the first suction fan 160 in the outdoor unit 100 operates, external fresh air is sucked into the outdoor unit 100 by the first suction fan 160 and is sent into the temperature-variable box 110 through the air inlet channel 180, after the evaporator 120 absorbs heat of the refrigerant in a gas-liquid mixed state, the fresh air entering the temperature-variable box 110 flows through the evaporator 120 under the combined action of the first suction fan 160 and the air supply fan 190, the heat of the fresh air is taken away to reduce the temperature, water vapor may be condensed to generate accumulated water in the process, and the accumulated water is discharged through the water discharge pipe 112; the cooled fresh air enters the air supply duct 300, enters the air duct box 210 of the indoor unit 200 under the action of the second suction fan 230, and is finally discharged into the room under the action of the air guide fan 220, so as to achieve the refrigeration effect after being mixed with the indoor air.
