DETAILED DESCRIPTION

[0028] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0029] 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 supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0030] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. 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 surrounding environment through the condensation process.

[0031] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid 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 refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0032] The air conditioner includes an evaporation unit and a condensation unit, the condensation unit refers to a part of the refrigeration cycle including a compressor and a condenser, the evaporation unit of the air conditioner includes an evaporator, and the expansion valve can be provided in the evaporation unit or the condensation unit. In the cooling state of the air conditioner, the air conditioner is used as a cooler in the cooling mode. At the same time, the air conditioner also has a heating capability, and when in the heating state of the air conditioner, the air conditioner is used as a cooler in the heating mode.

[0033] The evaporation unit is connected to a condensation unit installed in the space below the evaporation unit through a pipeline. The condensation unit may be provided with a compressor, a condenser, a second fan, an expander and components of a refrigeration cycle, and the evaporation unit may also be provided with an evaporator and a first fan.

[0034] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0036] Reference Figure 1-5 The present invention proposes an outdoor integrated energy cabinet, comprising: a cabinet 1, an equipment cabinet 2 and a fresh air cabinet 3; the equipment cabinet 2 is arranged in the cabinet 1, and the equipment cabinet 2 is provided with equipment 21; the fresh air cabinet 3 is arranged in the cabinet 1, and the fresh air cabinet 3 is provided with a fresh air module, and an isolated fresh air return space 37 and a fresh air supply space 38 are formed in the fresh air module, and a fresh air inlet 33 and a fresh air supply outlet 34 are formed on the fresh air return space 37, and a return air outlet 35 and an exhaust air outlet 36 are formed on the fresh air supply space 38. After the fresh air outside the cabinet enters from the fresh air inlet 33 and is heat-exchanged by the fresh air module, it flows from the fresh air supply outlet 34 to the equipment cabinet 2 and dissipates heat for the equipment 21, and the air after heat dissipation flows into the return air outlet 35, and is finally discharged to the outside of the cabinet 1 through the exhaust air outlet 36.

[0037] The outdoor integrated energy cabinet includes a cabinet 1 and a fresh air cabinet and a fresh air cabinet 3 arranged in the cabinet 1. The fresh air cabinet 3 is arranged in parallel with the fresh air cabinet. Multiple fresh air modules are arranged in the fresh air cabinet 3. Equipment 21 is arranged in the equipment cabinet 2. Multiple fresh air modules blow air into the equipment cabinet 2 to provide heat for the equipment 21.

[0038] The size of the fresh air cabinet matches the size of the fresh air cabinet 3. There are two ways of arranging the fresh air cabinet and the fresh air cabinet 3. In one embodiment, the number of equipment cabinets 2 is an even number, and the fresh air cabinet 3 is arranged in the middle of the equipment cabinet 2, and the fresh air module blows cold air to the equipment cabinets 2 on both sides; in another embodiment, the number of equipment cabinets 2 is an odd number, and the fresh air cabinet 3 is arranged on both sides of the equipment cabinet 2, and the equipment cabinets 2 on both sides blow relative to each other, and blows cold air to the equipment cabinet 2 in the middle.

[0039] By arranging the interior of the cabinet 1 according to the number of equipment cabinets 2, a short heat transmission distance and a small air volume loss can be achieved. In combination with the fan 6 with high static pressure and large air volume, the air flow in the cabinet 1 is evenly organized.

[0040] Since the fresh air module is small in size, multiple fresh air modules can be arranged in the fresh air cabinet 3. The number of fresh air modules can be increased or decreased according to the needs of the heating equipment 21 in the cabinet 1 to ensure modular expansion.

[0041] Partitions are added inside equipment cabinet 2 to form a channel that separates hot and cold.

[0042] An air flow channel surrounding the device 21 is formed between the cabinet 1 and the device 21, and an air flow circulation is formed between the fresh air module and the air flow channel.

[0043] A first partition 22 is provided in the air flow channel, and the first partition 22 divides the air flow channel into a cold air flow channel 24 and a hot air flow channel 23. The fresh air supply port 34 of the fresh air module delivers cold air into the cold air flow channel 24. After the cold air exchanges heat with the equipment 21, it flows from the hot air flow channel 23 to the return air port 35.

The supply air port is connected to the cold air circulation channel 24, and the return air port 35 is connected to the hot air circulation channel 23.

[0049] By setting a fresh air inlet 33 on the panel 31a on the front side of the fresh air module, the fresh air outside the cabinet can be sucked into the cold air circulation channel 24 in the cabinet by the fan 6 and sent to the air inlet of the equipment 21. An exhaust outlet 36 is set on the back panel 31e of the fresh air module, and the airflow in the hot air circulation channel 23 in the cabinet 1 is discharged outside the cabinet under the action of static pressure.

[0050] A fresh air unit is formed in the casing 31 , and a second partition plate 4 is provided to separate the fresh air unit into a fresh air supply space 38 and a fresh air return space 37 .

[0051] A first air valve 7 , a fan 6 and an electronic control device 10 are disposed in the casing 31 . The first air valve 7 is disposed in the fresh air return space 37 for discharging the airflow flowing in from the hot air circulation channel 23 from the exhaust port 36 .

[0052] The fan 6 and the electronic control device 10 are arranged in the fresh air supply space 38 .

[0053] The electric control device 10 is electrically connected to the first air valve 7 and the fan 6 , and is used to control the rotation of the fan 6 and the start-up of the first air valve 7 according to the temperature monitored in real time.

[0054] A filtering dust removal device 9 is arranged in the casing 31 , and the filtering dust removal device 9 includes a dust removal device and a filtering device. The filtering dust removal device 9 is arranged between the first air valve 7 and the fresh air inlet 33 , and is used to purify and filter the fresh air outside the cabinet entering from the fresh air inlet 33 .

[0056] The third partition plate 5 is also provided with a threading hole 53 , through which a connecting wire connected to the electric control device 10 is passed to connect to the first air valve 7 .

[0057] When the fresh air module is running, the first air valve 7 and the second air valve 8 are both in the open state. Under the action of the suction force of the fan 6, the fresh air outside the cabinet enters the casing 31 from the fresh air inlet 33, and after being purified and filtered by the filtering and dust removal device 9 and controlled by the first air valve 7, it flows from the fresh air supply port 34 to the cold air circulation channel 24.
