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 refrigerating cycle of the air conditioner by using the compressor 500, the condenser, the expansion valve, and the 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 500, the compressor 500 compresses the refrigerant gas in 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 500. 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.

The outdoor unit of the air conditioner refers to a portion of the refrigeration cycle including the compressor 500 and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the 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 air intake heat exchanger 300 and the air exhaust heat exchanger 400 are converted into a condenser or an evaporator, and generally use a four-way valve, and the arrangement of the conventional air conditioner is specifically referred to, which is not described 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.

Referring to fig. 1 and 2, a fresh air conditioner according to the present application includes an outer housing 100, where the outer housing 100 includes an upper cover plate (not shown), a lower cover plate 110, and a peripheral plate 120 located between the upper cover plate and the lower cover plate 110, the upper cover plate is used to connect with a building roof, the fresh air conditioner is integrally hung in the building, the lower cover plate 110 is located below the fresh air conditioner, and an access hole is formed in the lower cover plate 110, so that an operator can conveniently perform maintenance.

In order to avoid interference with the first refrigerant pipe 550, the second refrigerant pipe 560 is connected to the heat exchanger group around the bottom of either end of the compressor 500 after being connected to the compressor 500.

In order to facilitate the disassembly of the inner access plate by an operator, a handheld part bending towards the direction of the heat exchange core 200 is further formed on the inner access plate, and the inner access plate is disassembled by the operator through the handheld part when the inner access plate is disassembled.

The inner access cover 810 is formed with a threading part, which is a threading imaginary part or a threading hole, and a sealing plug is arranged on the threading hole.

Similar to the sealing plug in the wiring hole, the sealing plug on the threading part is also formed with a threading channel penetrating through, the sealing plug is made of rubber material and has certain sealing elasticity, and then the wire harness can pass through the wire harness channel and simultaneously ensure the sealing of the periphery of the wire harness.

When threading portion is the threading imaginary part, the threading imaginary part can be knocked down in the time of overhauing, passes the pencil after the maintenance from this position, and the threading imaginary part after knocking down also forms the through wires hole structure, in actual maintenance in-process, also for its configuration sealing plug, improves the leakproofness of threading portion after the pencil passes.

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

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
