Description

Technical Field

[0001] The utility model belongs to the technical field of precise air supply constant temperature and humidity, and particularly relates to a precise air supply constant temperature and humidity control device. Background Art

[0002] Precision Air Conditioning (PAC) is an air conditioning system specifically designed to maintain ambient temperature and humidity within very strict limits. This type of system is commonly used in data centers, laboratories, hospitals, industrial production, and other locations with stringent temperature and humidity control requirements. Its primary function is to ensure that equipment or experimental processes operate under optimal environmental conditions by precisely controlling air temperature, humidity, and air flow.

[0003] According to a public disclosure, a precision air supply constant temperature and humidity control device (publication number: CN220438804U) includes a main air conditioning unit, a secondary air conditioning unit, and a controller. The main air conditioning unit is connected to several groups of GIS control cabinets via pipes. The pipes above each GIS control cabinet are equipped with electric dampers to control air volume. Each GIS control cabinet is equipped with a temperature and humidity sensor to detect its temperature and humidity. This precision air supply constant temperature and humidity control device uses two direct expansion air conditioning units as cooling sources to deliver cold air to the control cabinet year-round. The two air conditioning units are one in use and one in backup, with automatic switching in the event of a failure. Each GIS control cabinet is equipped with a temperature and humidity sensor, and an electric damper is installed at the cabinet air inlet. The real-time monitored cabinet temperature and humidity values ​​are compared with the values ​​set on the control panel.

[0004] When the main air-conditioning unit, auxiliary air-conditioning unit and controller in the above application cannot cooperate with each other to achieve constant temperature control of air supply, we propose a precise constant temperature and humidity control device for air supply. Utility Model Content

[0008] Furthermore, the air supply constant temperature control device includes a motor, the motor is fixedly connected to the inner side surface of the control box, the output shaft of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the circumferential surface of the threaded rod is threadedly connected to a second threaded sleeve, the side of the control box is provided with an air supply port, the side of the control box is provided with a constant temperature port, the side of the air supply port is rotatably connected to an air supply rotating shaft, one end of the air supply rotating shaft is fixedly connected to an air supply rotating blade, the side of the threaded sleeve is fixedly connected to an L-shaped air supply pull rod, the side of the constant temperature port is rotatably connected to the constant temperature rotating shaft, one end of the constant temperature rotating shaft is fixedly connected to the constant temperature rotating blade, the side of the second threaded sleeve is fixedly connected to an L-shaped constant temperature pull rod, and the inner side surface of the control box is fixedly connected to a limit rod. The main function of the air supply constant temperature control device is to accurately control the position of each component in the air supply and constant temperature system by driving the rotation of the threaded rod by the motor, thereby adjusting the air flow and temperature to ensure the constant temperature and ventilation requirements of the environment. The function of the limit rod is to ensure that the adjustment of these components does not exceed the design range and maintain the stability and safety of the system.

[0009] Furthermore, one end of the L-shaped air supply lever is fixedly connected to the side of the air supply rotor blade, and one end of the L-shaped thermostatic lever is fixedly connected to the side of the thermostatic rotor blade. One end of the L-shaped air supply lever is fixedly connected to the side of the air supply rotor blade. The air supply rotor blade adjusts the opening of the air supply port by rotating, thereby controlling the air flow rate and direction of air supply.

[0010] Furthermore, the side surface of the threaded sleeve is slidably connected to the side surface of the limiting rod, and the side surface of the second threaded sleeve is slidably connected to the side surface of the limiting rod. The function of the limiting rod is to make the threaded sleeve and the second threaded sleeve perform reciprocating horizontal motion together with the slidably connected threaded sleeve and the second threaded sleeve.

[0011] Furthermore, an air supply rotating rod is rotatably connected between the air supply rotating blades, and a thermostatic rotating rod is rotatably connected between the thermostatic rotating blades. The air supply rotating rod and the thermostatic rotating rod enable the multiple air supply blades and the thermostatic blades to rotate synchronously, ensuring stable flow and temperature regulation of the system and avoiding uneven or inconsistent regulation effects.

[0012] Furthermore, a water scraper and collection device is provided on the side of the L-shaped air supply rod. The water scraper and collection device includes an extension rod fixedly connected to the side of the L-shaped air supply rod, a scraper fixedly connected to the side of the extension rod, a water collection trough fixedly connected to the side of the air supply device, and a water collection box slidably connected to the bottom of the trough. The water scraper and collection device is primarily used to collect and discharge moisture from air circulation equipment.

[0013] Furthermore, the side of the air supply device lies on the displacement path of the scraper, and the length of the scraper is consistent with the height of the air supply device. This design ensures that the scraper can scrape away any accumulated water droplets or film on the side of the air supply device without missing any area. The entire side of the device is fully scraped away, preventing moisture accumulation and ensuring normal operation of the device.

[0014] Furthermore, the scraper is constructed of rubber, and the water collection trough is inclined. The rubber material is flexible and can effectively adapt to the curves or irregular shapes of the sides of the air supply equipment, ensuring close contact between the scraper and the equipment surface. This allows the scraper to completely remove moisture from the surface, preventing leaks or incomplete scraping.

[0017] 2. The utility model starts the motor through the cooperation of the motor, the threaded rod, and the extension rod. The motor's output shaft rotates, driving the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to perform reciprocating horizontal motion under the restraining action of the limit rod. The reciprocating horizontal motion of the threaded sleeve drives the L-shaped air supply rod to perform reciprocating horizontal motion. The reciprocating horizontal motion of the L-shaped air supply rod drives the extension rod to perform reciprocating horizontal motion. The reciprocating horizontal motion of the extension rod drives the scraper to perform reciprocating horizontal motion.
