The present embodiment provides a fresh air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor 500, a condenser, an expansion valve, and an evaporator. The refrigeration and heating cycle includes a series of processes involving compression, condensation, expansion and evaporation and supplying a refrigerant medium to the conditioned and heat exchanged air.

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

The low-temperature low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas into a high-temperature 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 formed by condensation 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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an 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 function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.

The mode of converting the air inlet heat exchanger and the air outlet heat exchanger into a condenser or an evaporator generally adopts a four-way valve, and the arrangement of a conventional air conditioner is specifically referred to, and details are not repeated herein.

The refrigeration working principle of the air conditioner is as follows: the compressor 500 works to make the inside of the air intake heat exchanger 300 (in the air intake channel, at this time, the evaporator) in an ultra-low pressure state, the liquid refrigerant in the air intake heat exchanger 300 evaporates rapidly to absorb heat, the air blown out by the indoor fan is cooled by the coil pipe of the air intake heat exchanger 300 and then changed into cold air to blow into the indoor, the evaporated refrigerant is condensed into liquid state in the high pressure environment in the air exhaust heat exchanger 400 (in the air exhaust channel, at this time, the condenser) after being pressurized by the compressor 500, the heat is released, and the heat is dissipated into the atmosphere by the air exhaust fan 700, so that the refrigerating effect is achieved.

The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor 500 to become high-temperature and high-pressure gas, and enters the air intake heat exchanger 300 (a condenser in this case), and is condensed, liquefied and released to become liquid, and at the same time, the indoor air is heated, so that the purpose of increasing the indoor temperature is achieved. The liquid refrigerant is decompressed by the throttle device, enters the exhaust heat exchanger 400 (an evaporator at this time), evaporates and gasifies to absorb heat, becomes gas, absorbs heat of the outdoor air (the outdoor air becomes colder) and becomes a gaseous refrigerant, and enters the compressor 500 again to start the next cycle.

The heat exchange core 200 in the fresh air conditioner can be an efficient and energy-saving heat recovery device, and the introduced fresh air is preheated or precooled by recovering the waste heat in the exhaust gas, so that the enthalpy value of the fresh air is reduced or increased before the fresh air is subjected to heat-humidity treatment. The system load is effectively reduced, the energy consumption and the operation cost of the system are saved, and the contradiction between the improvement of the indoor air quality and the energy saving of the system is effectively solved.

As shown in fig. 11 and 12, the fresh air conditioner according to the present application includes an outer case 100, and the outer case 100 includes an upper cover 110, a lower cover 130, and a side plate group 120 located between the upper cover 110 and the lower cover 130.

The side plate set 120 is provided with an outdoor air inlet 101, an outdoor air outlet 102, an indoor air supply outlet 103 and an indoor air return outlet 104; an air supply channel is formed between the outdoor air inlet 101 and the indoor air supply opening 103, and an air exhaust channel is formed between the indoor air return opening 104 and the outdoor air exhaust opening 102.

An air inlet heat exchanger 300 is installed in the air supply channel, and an air exhaust heat exchanger 400 is arranged in the air exhaust channel.

The heat exchange core 200 is located between the outdoor air inlet area 1011 and the indoor air return area 1041, and in the actual working process, signals and electric energy are required to be transmitted between working components in the outdoor air inlet area 1011 and the indoor air return area 1041 through a wire harness.

The traditional wire harness connected between the outdoor air inlet area 1011 and the indoor air return area 1041 mainly directly passes through the heat exchange core 200 and the side plate group 120, and the connection mode easily causes gaps on the periphery of the wire harness, so that air flows between the outdoor air inlet area 1011 and the indoor air return area 1041 circulate mutually from the gaps, and the working effect of the air conditioner is affected.

And the wire harness is directly contacted with the heat exchange core 200, friction is generated between the wire harness and the heat exchange core 200, abrasion is generated between the wire harness and the heat exchange core 200, and the service lives of the wire harness and the heat exchange core 200 are affected.

The outer surface of the second contact surface 913 is flush with the surface of the foaming member 900, so that the outer sides of the second contact surface 913 and the foaming member 900 are in a plane and are in contact connection with the heat exchange core 200, and the generation of connection gaps is reduced.

The wire passing member 910, the side plate set 120 and the foaming member 900 are surrounded to form a wire passing channel, and two ends of the wire passing channel are respectively communicated with the outdoor air inlet area 1011 and the indoor air return area 1041, so that a wire harness between the outdoor air inlet area 1011 and the indoor air return area 1041 passes through.

That is, after the first contact surface 912 of the wire passing member 910 is connected to the inner wall of the side plate set 120, each relief portion 901 of the foam member 900 is corresponding to each wire passing member 910.

The sealing piece can be of a sealing rubber strip and other structures, after the wire harness passes through the threading channel, other areas in the threading channel are plugged through the sealing strip, so that air flow passing between the outdoor air inlet area 1011 and the indoor air return area 1041 is reduced, and the sealing effect is improved.
