Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit equipment, and in particular to a sealing door for air conditioning units. Background Technology

[0002] Cleanroom air conditioners achieve functions such as cooling, heating, dehumidification, humidification, and sterilization through various heat and humidity treatment methods and air purification, thereby achieving precise control over the temperature, humidity, and cleanliness of the indoor environment.

[0003] Currently, condensation easily forms on the outside of the access door of air conditioning units. The specific principle is that when the evaporator inside the air conditioning unit is running, the refrigerant absorbs heat and cools the air inside the unit. Through energy transfer, the surface temperature of the outside of the unit is reduced. If the air temperature outside the access door is high, the water vapor in the air will cool and condense into water droplets when it comes into contact with the low temperature surface of the access door, which is the phenomenon of condensation. When the relative humidity of the air outside the air conditioning unit is high, condensation is more likely to occur.

[0004] The presence of condensate can lead to the growth of microorganisms, such as bacteria and mold. These microorganisms can be spread through the air, thus contaminating the cleanroom environment and reducing air cleanliness. Long-term accumulation of condensate may cause rust and corrosion of the external metal parts of the unit, especially on metal surfaces, which may affect the service life and stability of the equipment. If too much condensate accumulates, it may drip onto the outside of the cleanroom air conditioning unit or the surrounding environment, making the ground in the area wet and creating a potential slip risk, especially when operators are performing maintenance or repairs, increasing safety hazards. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an air conditioning unit sealing door that prevents condensation from forming on the outside of the door, improves air cleanliness, extends the service life of the equipment, and reduces safety hazards.

[0007] An air conditioning unit sealing door includes a swing door, which includes an inner door panel, an outer door panel, and four frame edge assemblies connected in sequence to form a frame. Each frame edge assembly includes an inner frame edge, a partition strip, and an outer frame edge. The inner side of the outer frame edge is provided with a first T-shaped groove, and the outer side of the inner frame edge is provided with a second T-shaped groove. The two sides of the partition strip are respectively engaged in the first T-shaped groove and the second T-shaped groove. The inner door panel is connected to the inner side of the inner frame edge, and the outer door panel is connected to the outer side of the outer frame edge.

[0008] Preferably, a square tube is connected to the top of the outer frame, the outer door panel is connected to the outside of the square tube, an inverted L-shaped strip is connected to the bottom of the inner frame, and the inner door panel is connected to the inside of the inverted L-shaped strip.

[0009] Preferably, the system also includes a door frame, which is hinged to the outer door panel. A first frame-shaped adhesive strip and a second frame-shaped adhesive strip are connected to the door frame. The outer side of the first frame-shaped adhesive strip is in contact with the inner side of the square tube strip, and its lower side is in contact with the upper side of the inner frame edge. The outer side of the second frame-shaped adhesive strip is in contact with the inner side of the inner frame edge, and its lower side is in contact with the upper side of the inverted L-shaped strip.

[0010] Preferably, a raised strip is provided on the upper side of the middle part of the partition strip, and the upper side of the raised strip is flush with the upper side of the inner frame edge, and the lower side of the first frame-shaped adhesive strip is in contact with the upper side of the raised strip.

[0011] Preferably, the front of the swing door is rotatably connected to a handle, which is connected to a pivot. The pivot passes through the outer door panel and the inner door panel in sequence and is connected to a limit switch. The limit switch moves and abuts against the inner side of the door frame.

[0012] Preferably, the hinged door has an observation window assembly in the middle.

[0013] Preferably, the observation window assembly includes an inner glass plate, an outer glass plate, and a spacer ring. The inner glass plate is fixed to the middle of the inner door panel, the outer glass plate is fixed to the middle of the outer door panel, and the spacer ring connects the inner glass plate and the outer glass plate.

[0014] Preferably, both the spacer ring and the spacer bar are made of PVC.

[0015] The beneficial effects of this utility model are as follows:

[0016] The air conditioning unit's sealed door uses a partition strip to separate the inner and outer frame edges, forming a thermal break structure. This separates the inner and outer door panels, preventing the low temperature of the inner door panel from being transferred to the outer door panel. This ensures a stable temperature on the surface of the outer door panel, preventing condensation from forming on the outer door panel surface, improving air cleanliness, extending the equipment's service life, and reducing safety hazards.
