The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Outdoor cabinet is used for holding the basic station, and when new trend was energy-conserving to be applied to outdoor cabinet, need broken hole transformation to outdoor cabinet to install new trend equipment, nevertheless difficult operation when broken hole, the construction transformation is comparatively inconvenient. The embodiment of the utility model provides an outdoor cabinet integration fresh air conditioner 100, as integration fresh air conditioner, can realize the two guarantees of fresh air cooling and mechanical refrigeration, need not to carry out the later stage to outdoor cabinet and reforms transform.

The structure of the above-mentioned outdoor cabinet integrated fresh air conditioner 100 is exemplified below, for example, in some embodiments of the present application, as shown in fig. 1, the outdoor cabinet integrated fresh air conditioner 100 may include a casing 1, a condenser 2, an evaporator 3, and an electric air valve 4. The casing 1 has a first accommodating cavity 11 and a second accommodating cavity 12, and the first accommodating cavity 11 is provided with a first air inlet 111 and a first air outlet 112 communicated with the outdoor. The second accommodating cavity 12 is opened with a second air outlet 122 and a second air inlet 121 which are communicated with the inside of the outdoor cabinet. The condenser 2 is disposed in the first accommodating cavity 11 and located at the first air outlet 112. The evaporator 3 is disposed in the second accommodating cavity 12 and located at the second air outlet 122. Thus, the evaporator 3 can cool the inside of the outdoor cabinet.

In addition, the electric air valve 4 is disposed between the first accommodating chamber 11 and the second accommodating chamber 12 as shown in fig. 1, and the electric air valve 4 is used for communicating the first air inlet 111 with the second air outlet 122 and communicating the second air inlet 121 with the first air outlet 112 in the open state. Alternatively, as shown in fig. 2, the electric damper 4 is configured to communicate the second inlet 121 with the second outlet 122 and communicate the first inlet 111 with the first outlet 112 in the closed state.

Under the condition, fresh air cooling and mechanical refrigeration can be automatically switched according to outdoor temperature, when the outdoor temperature is higher than a certain threshold value, for example, 35 ℃, the mechanical refrigeration is started, at the moment, as shown in fig. 2, the electric air valve 4 is closed (namely, the electric air valve 4 is in an open state parallel to the Y axis), as shown in the direction indicated by the arrow on the right side of fig. 2, the fresh air flows to the outdoor. The fresh outdoor air can enter the first accommodating cavity 11 through the first air inlet 111, the filter and the condenser 2, and is output to the outdoor through the first air outlet 112. In this way, the hot air in the outdoor cabinet can be transmitted to the outside to reduce the temperature. As indicated by the direction of the arrow on the left side of fig. 2, is the indoor return air flow direction. Indoor return air enters the second accommodating cavity 12 from the second air inlet 121, passes through the evaporator 3 and is discharged into the room from the second air outlet 122, so that the room is cooled.

When the outdoor temperature is lower than a certain threshold value, for example, 25 ℃, fresh air refrigeration is started, and at this time, as shown in fig. 3, the electric air valve 4 is opened (that is, the extension line of the electric air valve 4 and X form a cross opening state). As shown by the direction of the arrow below fig. 3, the fresh air flows outdoors. Outdoor fresh air enters the first accommodating cavity 11 from the first air inlet 111, enters the second accommodating cavity 12 through the electric air valve 4, passes through the evaporator 3 and is discharged into the room from the second air outlet 122, and therefore the temperature of the room is reduced. As indicated by the direction of the arrow above fig. 3, is the indoor return air flow direction. The indoor return air enters the second accommodating cavity 12 from the second air inlet 121 shown in fig. 3, passes through the electric air valve 4, enters the first accommodating cavity 11, passes through the condenser 2, and is discharged to the outside from the first air outlet 112. When outdoor new trend is not enough to cool down indoor, also can start fresh air cooling and mechanical cooling simultaneously, cool down indoor simultaneously.

In this way, the condenser 2 is cooled by allowing more gas entering the first receiving chamber 11 to contact the condenser 2. As shown in fig. 4, the condenser 2 in the embodiment of the present invention may be obliquely disposed in the first accommodating chamber 11, and one end of the condenser 2 close to the first air inlet 111 abuts against an inner wall of the first accommodating chamber 11 on the side where the first air outlet 112 is disposed. In this way, the fresh outdoor air entering the first accommodating cavity 11 can contact the condenser 2 more (the air passes through the inclined heat dissipation surface of the condenser 2 first). If the condenser 2 is vertically arranged, although the temperature of the condenser 2 can be reduced, since the gas flows from bottom to top and then is discharged to the outside from the first air outlet 112 to the right, in this case, the gas passes through the bottom of the condenser 2 and then passes through other parts of the condenser 2, and the temperature reduction efficiency is lower than that of the former.

In order to provide kinetic energy for the air in the fresh air refrigeration and the mechanical refrigeration, as shown in fig. 5, the outdoor cabinet integrated fresh air conditioner 100 may further include a first fan 5 and a second fan 6. The first fan 5 is disposed in the first accommodating cavity 11 and near the first air inlet 111. The second fan 6 is disposed in the second accommodating chamber 12 and located at the second air inlet 121.

Based on this, the first fan 5 in the first accommodating cavity 11 provides kinetic energy for the fresh outdoor air entering the first accommodating cavity 11 from the first air inlet 111, and during mechanical refrigeration, as shown by an arrow on the right side of fig. 5, the first fan 5 can discharge the fresh outdoor air into the first accommodating cavity 11, so as to be discharged to the outside from the first air outlet 112. As shown by the left arrow in fig. 5, the second fan 6 in the second accommodating chamber 12 can discharge the indoor return air into the second accommodating chamber 12 through the second air inlet 121 and then into the room through the second air outlet 122. When the fresh air is cooled, as shown by the arrow at the lower part in fig. 6, the outdoor fresh air enters the first accommodating cavity 11 through the first air inlet 111, enters the second accommodating cavity 12, and is discharged into the room through the second air outlet 122, so that the temperature of the room is reduced. As shown by the upper arrow in fig. 6, the second blower 6 discharges the indoor return air from the second air inlet 121 into the second accommodating chamber 12, then into the first accommodating chamber 11, and then out of the room through the first air outlet 112. Thereby discharging the indoor hot air to the outdoor to reduce the temperature. Based on this, the first fan 5 and the second fan 6 can provide kinetic energy for the fresh air cooling and the mechanical cooling gas.

In order to realize continuous cooling of the evaporator 3 in the above embodiment, as shown in fig. 7, the outdoor cabinet integrated fresh air conditioner 100 may further include a refrigeration compressor 7, an electronic expansion valve 8 and a refrigeration pipe 9. The refrigeration compressor 7 is disposed in the first accommodation chamber 11 shown in fig. 8. Wherein fig. 8 is a schematic view of a direction a in fig. 5, and a refrigerant pipe 9 is used to communicate the refrigerant compressor 7, the condenser 2, and the evaporator 3. The electronic expansion valve 8 is disposed on the refrigerating pipe 9 between the evaporator 3 and the condenser 2, and is communicated with the refrigerating pipe 9 and the evaporator 3.

In this case, as shown in fig. 7, the refrigeration compressor 7 is configured to compress the low-pressure and low-temperature refrigerant vapor from the generator 3 into high-pressure and high-temperature vapor, and then the refrigerant vapor enters the condenser 2 to release heat to form high-pressure and high-temperature vapor. The electronic expansion valve 8 is used for throttling the high-pressure high-temperature steam to form low-pressure low-temperature steam, and the low-pressure low-temperature steam passes through the evaporator 3 to exchange heat with the gas to form low-pressure low-temperature refrigerant steam, so that circulating refrigeration is realized. Thus, the refrigerant fluid can circulate and refrigerate in the refrigerating pipe 9, so that the evaporator 3 can continuously cool the indoor space.

As can be seen from the above, the heat of the condenser 2 in the first receiving chamber 11 is taken away by the gas entering the first receiving chamber 11, and the refrigerant liquid in the refrigerant pipe 9 can be cooled. Since the refrigerant pipe 9 communicates the condenser 2 and the evaporator 3, the cooled coolant can flow into the evaporator 3 through the refrigerant pipe 9. Thus, when the evaporator 3 cools the indoor space, the refrigerant fluid is heated by the indoor air, thereby absorbing heat of the indoor air and achieving the purpose of reducing the indoor air temperature. So that the evaporator 3 can cool the air entering the second accommodating chamber 12 from the second air inlet 121 and then input the cooled air into the room through the second air outlet 122.

Under this condition, no matter be fresh air cooling or mechanical refrigeration, outdoor new trend all need enter into first holding chamber 11 through first air intake 111 earlier, so, because have dust particulate matter in the outdoor new trend, can form certain laying dust on the equipment surface when outdoor new trend passes through the equipment in the cabinet to influence the heat dissipation of equipment, influence the normal operating of equipment even.

Based on this, as shown in fig. 9, the outdoor cabinet integrated fresh air conditioner 100 may further include a filter 10 disposed in the cabinet 1 and close to the first air inlet 111. Wherein, the filter 10 can adopt a G4 grade primary filter, and the head-on wind speed is less than or equal to 2.5m/s. Therefore, when outdoor fresh air enters the first accommodating cavity 11, the fresh air enters the second accommodating cavity 12 after passing through the filter 10, and under the condition, the cleanliness of the air entering the second accommodating cavity 12 after the outdoor fresh air is filtered by the filter 10 is improved. The failure rate of equipment in the air conditioning system and the outdoor cabinet is reduced.

In addition, the filter 10 mentioned above is blocked after long-term use, so that fresh outdoor air cannot smoothly enter from the first air inlet 111 and then passes through the filter 10, and therefore, the filter 10 needs to be periodically maintained and cleaned. However, if the outdoor cabinet is installed in a remote area, the filter 10 cannot be cleaned without being attended by a person.

Based on this, as shown in fig. 10, the outdoor cabinet integrated fresh air conditioner 100 may further include a dust removing assembly 101 disposed in the first accommodating chamber 11, where the dust removing assembly 101 is located between the filter 10 and the first air inlet 111 and is used for removing dust from the filter 10. In this way, when the dust accumulated on the filter 10 reaches a certain amount, the dust removing assembly 101 can be controlled to clean the dust accumulated on the filter 10. In this case, the dust removing assembly 101 can automatically clean the filter 10, reducing the cost of personnel maintaining the filter 10.

The above mentioned dust removing assembly 101 structure is exemplified below, for example, in some embodiments of the present application, as shown in fig. 11, the dust removing assembly 101 may include a guide rail 1011, a dust suction chamber 1012 and a dust removing fan 1013. The guide rail 1011 is disposed in the first accommodating chamber 11 and between the filter 10 and the first air inlet 111. The guide rails 1011 extend in a direction parallel to the web surface of the filter 10. The dust suction chamber 1012 is disposed in the first receiving chamber 11 between the filter 10 and the guide rail 1011. As shown in figure 12, the side of the cleaning chamber 1012 adjacent the rail 1011 is slidably connected to the rail 1011. A dust suction port a is opened at one side of the dust suction cavity 1012 close to the filter 10. The dust removing fan 1013 has a dust removing air inlet b and a dust removing air outlet c, wherein the dust removing air inlet b is communicated with the dust collecting cavity 1012, and the dust removing air outlet c is communicated with the outside. Thus, the outdoor space communicates with the dust suction port a. The dust at the dust suction port a can be discharged to the outside.

In this case, when certain dust particles are accumulated on the surface of the filter 10, the dust collection cavity 1012 can be controlled to slide along the guide rail 1011, the dust removal fan 1013 is started, negative pressure is formed in the dust collection cavity 1012, and the dust collection port a of the dust collection cavity 1012 generates certain suction force to adsorb dust on the filter 10, and after the dust enters the dust collection cavity 1012, the dust is guided out to the dust collection air outlet c from the dust collection air inlet b of the dust removal fan 1013 along with the flow guiding direction of the dust removal fan 1013 so as to be discharged outdoors. Thereby achieving dust removal of the filter 10.

In order to provide kinetic energy for the above-mentioned dust suction chamber 1012 to slide along the guide rail 1011, the dust removing assembly 101 of the embodiment of the present application may further include a motor 102, a first wire 103 and a second wire 104 as shown in fig. 13. As shown in fig. 13, the motor 102 includes a motor shaft 1021, and the motor 102 is mounted on the dust-collecting chamber 1012. One end of the first wire rope 103 is wound around the motor shaft 1021, and the other end is connected with the inner wall of one side of the first accommodating cavity 11. One end of the second wire rope 104 is wound around the motor shaft 1021, and the other end is connected to the inner wall of the first accommodating cavity 11 on the opposite side. Thus, the motor shaft 1021 of the motor 102 can be pulled when wound around the wire rope, thereby moving the dust suction chamber 1012 fixed to the motor 102.

In this case, when the dust removing assembly 101 removes dust, the motor 102 is started to rotate, and since the first wire rope 103 and the second wire rope 104 are wound around the motor shaft 1021, the first wire rope 103 can be wound when the motor 102 rotates forward, and the second wire rope 104 is released at the same time, so that the first wire rope 103 can drive the dust collecting cavity 1012 fixed with the motor 102 to slide towards the first wire rope 103. When the motor 102 rotates reversely, the second wire rope 104 can be wound, and the first wire rope 103 is released, so that the second wire rope 104 can drive the dust collection cavity 1012 fixed with the motor 102 to slide towards the second wire rope 104.

In addition, in order to facilitate the maintenance of the dust removing assembly 101, as shown in fig. 14, the outdoor cabinet integrated fresh air conditioner 100 may further include a cover plate 105 and a drawing portion 106, wherein the bottom of the first accommodating cavity 11 is further provided with an installation cavity 13, the installation cavity 13 is provided with an installation opening 131, and the cover plate 105 is disposed at the installation opening 131 and hinged to one side of the installation opening 131. The drawing part 106 is provided with a bearing cavity 1061, the dust removing assembly 101 mentioned above is installed in the bearing cavity 1061, and the drawing part 106 is slidably connected to the installation cavity 13, for example, in some embodiments of the present application, a pulley 108 may be disposed at the bottom of the drawing part 106, and a sliding rail 107 may be installed at the bottom of the installation cavity 13, so that the drawing part 106 may slide in the installation cavity 13.

In this case, when the dust removing assembly 101 needs to be serviced, since the cover plate 105 and the mounting opening 131 are hinged, the cover plate 105 can be turned over (the cover plate 105 is turned up as shown in fig. 14), and the pull-out portion 106 is exposed. Since the drawing part 106 is slidably connected to the mounting cavity 13, the drawing part 106 can be slidably drawn out of the mounting cavity 13, and finally the dust removing assembly 101 in the bearing cavity 1061 of the drawing part 106 is repaired. The installation process of the pull-out part 106 after maintenance is reversed, and will not be described herein.

As the outdoor cabinet is arranged outdoors, the outdoor cabinet integrated fresh air conditioner 100 also needs to be arranged outdoors, especially under severe conditions, and in order to ensure more stable operation of the air conditioner, as shown in fig. 15, the outdoor cabinet integrated fresh air conditioner 100 may further include a flange 109, the flange 109 is arranged on the outer surface of the casing 1, and the flange 109 is used for installing the outdoor cabinet integrated fresh air conditioner 100. In this way, the flange 109 can be fixed to the ground surface or other structure to be fixed, thereby stabilizing the whole air conditioner.

In order to enable the dust removal assembly 101 to remove dust more intelligently, and therefore the manual maintenance cost is reduced. The outdoor cabinet integrated fresh air conditioner 100 further includes a differential pressure sensor 110 and a controller 1001 as shown in fig. 16. Wherein, the controller 1001 may be a PLC controller (i.e., a programmable logic controller), and the differential pressure sensor 110 is disposed between the first intake vent 111 and the filter 10 in the first receiving chamber 11 shown in fig. 11. The differential pressure sensor 110 is used for acquiring an air pressure value of the filter 10 near the first air inlet 111. The controller 1001 is electrically connected with the differential pressure sensor 110 and the dust removal assembly 101, and the differential pressure sensor 110 is configured to receive an air pressure value and compare the air pressure value with a first preset threshold and a second preset threshold. And if the air pressure value is greater than or equal to a first preset threshold value, controlling the dust removal assembly 101 to operate. And if the air pressure value is smaller than a second preset threshold value, controlling the dust removal assembly 101 to be closed. Wherein the first preset threshold may be greater than the second preset threshold.

In this way, the controller 1001 may determine whether to perform dust removal on the filter 10 according to the measurement value of the differential pressure sensor 110, and the controller 1001 may compare the pressure signal collected by the differential pressure sensor 110 with the first preset threshold and the second preset threshold, so as to control whether to activate the dust removal assembly 101.
