The guide rail 603 is connected with the sealing matching member 601, and the roller 602 is arranged in rolling manner on the guide rail 603. The guide rail 603 extends along the movement direction of the door body 20 and is arranged in inclined manner in the height direction. The roller 602 can roll along the guide rail 603 between a first position and a second position. When the door body is closed, the roller 602 moves to the first position along the guide rail 603, and the sealing member 60 is in sealing contact with the sealing matching member 601. When the door body is opened, the roller 602 moves to the second position along the guide rail 603, and the sealing member 60 is separated from the sealing matching member 601.

[0050] In the embodiment of the present disclosure, the sealing member 60 and the roller 602 are arranged at the sliding end portion of the door body 20, and the sealing matching member 601 and the inclined guide rail 603 connected therewith are arranged at the cabinet opening. The sliding movement of the roller 602 along the guide rail 603 can accurately control the contact and separation of the sealing member 60 and the sealing matching member 601. When the roller 602 moves to the first position, the sealing member 60 closely contacts with the sealing matching member 601, thereby forming a reliable sealing effect, effectively preventing cold air leakage and improving the heat preservation performance of the refrigeration equipment. When the roller 602 moves to the second position, the sealing member 60 is separated from the sealing matching member 601, and the door body 20 can be smoothly opened, thereby improving the convenience of operation. The inclined guide rail 603 not only provides a clear movement path for the roller 602, but also adjusts the distance between the sealing member 60 and the sealing matching member 601, so as to realize the sealing of the sliding end portion of the sliding door body 20. In this way, the sealing problem of the sliding end portion of the sliding door body 20 is improved, thereby improving the sealing effect, effectively preventing cold air leakage, reducing energy consumption, improving the overall performance and energy efficiency ratio of the refrigeration equipment, and avoiding or reducing condensation.

[0051] Optionally, the sliding end portion is located at the top of the door body 20 and / or the bottom of the door body 20. That is, the sliding end portion at the top and the bottom of the door body 20 can be in sliding connection with the cabinet opening.

[0052] Optionally, the sealing fitting 601 is an elastic member, the guide rail 603 is inclined away from the door body 20 in the closing direction of the door, and the sealing fitting 601 is elastically deformed when the roller 602 moves from the second position to the first position, and the sealing fitting 601 moves toward the sealing member 60 under the drive of the guide rail 603; when the roller 602 moves from the first position to the second position, the sealing fitting 601 restores to the original state, and the guide rail 603 moves away from the sealing member 60 under the drive of the sealing fitting 601.

[0100] In the embodiments of the present disclosure, the door 20 is arranged at the cabinet opening in a sliding manner, so that the space occupied by the opening and closing of the door 20 can be reduced, and the convenience and flexibility of the placement space of the refrigeration equipment can be improved. The air outlet duct 50 is in communication with the compressor cabin 40, so that the high-temperature airflow in the compressor cabin 40 can flow to the air outlet duct 50, and the high-temperature airflow in the air outlet duct 50 can be blown from the air outlet hole 504 to the door 20, so as to improve the temperature of the door 20 and the components around the door 20, and prevent or reduce the condensation of the door 20. The air outlet duct 50 can extend along the height direction of the cabinet opening, so as to improve the air outlet range in the height direction of the door 20, or the air outlet duct 50 can extend in the circumferential direction of the cabinet opening, so as to improve the air outlet range in the circumferential direction and prevent the condensation of the door 20. In addition, a plurality of fans are arranged in the air outlet duct 50, so that the plurality of fans can blow air from multiple positions, improve the uniformity and diversity of the air outlet, and then the number of working fans can be adjusted according to the condensation condition of the door 20, so as to improve the anti-condensation effect.

[0101] Optionally, the refrigeration equipment can be a medical refrigeration box, a household refrigeration refrigerator, or a wine cabinet, etc. The refrigeration equipment with a sliding door is an optional embodiment of the present application.

[0102] Optionally, the air outlet duct 50 is arranged outside the door 20 in the circumferential direction, so that the air outlet duct 50 will not affect the opening and closing of the door 20, and can blow air to the door 20 with the maximum area, and can also take into account the connection between the door 20 and the cabinet opening, blow air from multiple directions, improve the temperature of the door 20 and the components around the door 20, and reduce the condensation of the door 20 itself and the connection between the door 20 and the cabinet opening.

[0103] Optionally, the refrigeration equipment further comprises a controller and a first detection device, the controller is electrically connected with the plurality of fans and is configured to control the working of the plurality of fans, and the first detection device is configured to detect the humidity outside the door; wherein the first detection device is electrically connected with the controller, and the controller is configured to control the working of the plurality of fans according to the humidity outside the door.

[0104] In the embodiments of the present disclosure, the first detection device is a humidity sensor or a temperature and humidity sensor, so that the humidity outside the door body can be detected. In this way, the controller can obtain the humidity outside the door body in real time, and then control the operation of the plurality of fans according to the humidity information. The refrigeration equipment can intelligently adjust the working state of the fan according to the humidity data of the door body outside detected by the first detection device in real time. When the humidity is too high, the controller starts the fan to blow air to the door body 20, which not only can form a uniform airflow barrier to prevent water vapor from approaching the door body 20, but also can increase the temperature of the door body 20 to prevent the surface temperature of the door body 20 from being too low to cause condensation. When the humidity is low, the controller can reduce the power of the fan or suspend the operation to save energy.

[0105] Here, the first detection device can be one or more, and the first detection device is arranged outside the cabinet body 10 or the door body.

[0108] Optionally, the refrigeration equipment further comprises a condensing fan 403. In the case that the plurality of fans are turned on, and the humidity outside the door body is greater than or equal to a second preset humidity, the refrigeration equipment obtains the exhaust pressure of the compressor 401. When the exhaust pressure is less than or equal to a preset pressure, the controller controls the condensing fan 403 to reduce the rotating speed to increase the temperature of the condenser 402, wherein the second preset humidity is greater than the first preset humidity.

At this time, the rotating speed of the condensing fan 403 can be reduced, the heat exchange efficiency of the condenser 402 is reduced, and the temperature of the condenser 402 is increased. In this way, the heat exchange amount of the condenser 402 to the compressor cabin 40 is increased, and the temperature of the airflow in the compressor cabin 40 is increased. Therefore, the temperature of the airflow flowing out of the air outlet hole 504 of the air outlet duct 50 is relatively high, which can increase the temperature of the door body 20, so that the temperature of the door body 20 is higher than the dew point temperature of water, preventing the water vapor from condensing into water droplets, and improving the anti-condensation effect.
