Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning units, and in particular to a constant temperature and humidity air conditioning unit. Background Technology

[0002] Energy-efficient constant temperature and humidity air conditioning units are air conditioning systems designed to provide constant temperature and humidity control while prioritizing energy efficiency. These systems are typically used in locations requiring the maintenance of specific environmental conditions, such as laboratories, medical facilities, and production workshops.

[0003] In the prior art, patent document CN208519873U discloses an improved energy-saving constant temperature and humidity air conditioning unit, including a main unit installed on an outdoor wall, at least one air outlet box installed on an indoor wall, and an electrical control box installed on an indoor wall. The air inlets of the main unit and the air outlet box are connected through an air supply duct. The return air inlet of the main unit is equipped with a temperature sensor and a humidity sensor. This return air inlet is connected to the main unit through a return air duct, which contains an electric return air valve. The main unit contains a heat recovery heating coil, an electrode humidifier, a PTC auxiliary heater, a condenser, a compressor, an evaporator, a throttling valve, a motor, and a blower. The blower is connected to the motor. The electric return air valve, temperature sensor, heat recovery heating coil, humidity sensor, electrode humidifier, PTC auxiliary heater, condenser, compressor, and motor are connected to the electrical control box. The air outlet box is equipped with an adjustable-angle jet-type air outlet.

[0004] During use, it was found that the gas recovered through the return air vent is generally filtered inside the main unit by a filter plate. However, the filter plate has a limited lifespan, and replacing it may require shutting down the main unit, which is not very convenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a constant temperature and humidity air conditioning unit.

[0006] This utility model discloses a constant temperature and humidity air conditioning unit, including an inner unit casing, a control panel, an air outlet, and an air inlet. The air outlet is located at the top of the inner unit casing, the control panel is located at the side of the inner unit casing, and the air inlet is located at the front of the inner unit casing. It also includes a filter assembly, which is installed on the inner unit casing. The filter assembly seals the air inlet and filters dust from the incoming air. When the inner unit casing is started via the control panel, outside air enters the inner unit casing after being filtered for dust by the filter assembly, is cooled, and is then discharged through the air outlet. The dust filtration by the filter assembly reduces the frequency of use of the filter plates inside the inner unit casing and improves the service life of the filter plates.

[0007] Preferably, the filter assembly includes a base plate, upright plates, a square frame, a filter body, guide plates, and bolts. The base plate is installed at the front of the inner casing. A set of upright plates is provided on the left and right sides of the top of the base plate. A sliding groove is provided at the end of the two sets of upright plates that are close to each other. Each set of upright plates is threadedly connected to a set of bolts. The filter body is installed inside the square frame. A set of guide plates is provided on the left and right sides of the square frame. Each set of guide plates is provided with a set of round holes. In use, the two sets of guide plates of the square frame slide in a set of sliding grooves, so that the bottom of the square frame contacts the top of the base plate, and the filter body seals the control panel. Then, the bolts are rotated to insert the bolts into the round holes to lock the square frame. The filter body filters dust in the incoming air. When it is necessary to clean the dust from the filter body, the square frame and the filter body can be disassembled and cleaned without stopping the inner casing.

[0008] Preferably, it also includes an air guide assembly. The air guide assembly is provided at the top of the inner casing. The air guide assembly includes an air guide shroud, an L-shaped air guide pipe, vertical plates, a lead screw, a throttle, and a rotary joint. The air guide shroud is installed at the top of the inner casing. Two sets of L-shaped air guide pipes are rotatably connected to the top of the air guide shroud through a set of rotary joints. Two sets of vertical plates are provided at the top of the air guide shroud. Each set of vertical plates is threadedly connected to a set of lead screws. A throttle is provided at the end of each set of lead screws away from the L-shaped air guide pipes. According to the cooling needs, the operator adjusts the direction of the L-shaped air guide pipes with the help of the rotary joints. After the adjustment is completed, the lead screws are rotated by the throttle, so that the lead screws press against the outer wall of the L-shaped air guide pipes, thereby locking the L-shaped air guide pipes. The cold air discharged from the air outlet is transported through the guide of the L-shaped air guide pipes, improving flexibility.

[0009] Preferably, it also includes self-locking casters, with a set of self-locking casters provided at each of the four corners of the bottom of the inner chassis; the inner chassis can be adjusted in position with the cooperation of the four sets of self-locking casters, improving convenience.

[0010] Preferably, it also includes rings and slots. Each set of L-shaped air guide tubes has a set of rings fitted on its outer side wall, and each set of rings has multiple sets of slots at equal intervals on its outer side wall. After the L-shaped air guide tube is adjusted, the operator rotates the screw by turning the handle, so that the screw is inserted into a set of slots to lock the L-shaped air guide tube and improve its firmness.

[0011] Preferably, it also includes a handle, with a handle installed at the top of the frame; the staff can pull the frame out by using the handle, improving convenience.

[0012] Preferably, it also includes a square-shaped sealing gasket, wherein a square-shaped sealing gasket is provided at the front end of the inner casing, and the air inlet is inside the square-shaped sealing gasket; when the filter body seals the air inlet, the rear end of the square frame contacts the square-shaped sealing gasket, and the square-shaped sealing gasket seals the gap between the inner casing and the square frame to prevent dust from entering the interior of the inner casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: when the inner unit is started through the control panel, the outside air enters the inner unit after being filtered for dust by the filter assembly, is cooled, and is then discharged through the air outlet. The filter assembly reduces the frequency of use of the filter plate inside the inner unit and improves the service life of the filter plate. Attached Figure Description
