Description

Technical Field

[0001] The present invention relates to the technical field of constant temperature and humidity air-conditioning units, and in particular to a bidirectional energy-saving constant temperature and humidity air-conditioning unit. Background Art

[0002] Nowadays, the requirements for temperature and humidity in laboratories, the pharmaceutical industry, industrial production and other fields are gradually increasing. Many industries have strict requirements on the temperature and humidity in the air to ensure the accuracy, efficiency and safety of production or experiments. For example, electronic components and products are very sensitive to temperature and humidity during the production process. Excessively high or low humidity may affect the performance of electronic components or cause equipment failure.

[0003] Existing constant temperature and humidity air conditioning units mostly use membrane cloth humidifiers for humidification. The working principle of membrane cloth humidifiers is to use the ultra-fine pores of the membrane cloth to allow water to evaporate through the surface of the membrane cloth, thereby increasing the humidity in the air. The membrane cloth is usually made of polymer materials and has a very fine pore structure. When water flows through the surface of the membrane cloth, the water enters the air in the form of water vapor, thereby achieving the humidification effect. However, this humidification method requires the airflow to completely pass through multiple layers of wet membrane cloth before entering the ventilation duct. Therefore, once the humidifier is turned on, the wind force is greatly reduced. In order to ensure the ventilation volume, the fan power must be increased, thereby increasing the overall energy consumption. Secondly, this method makes it easier for the membrane cloth to adhere to floating dust in the air. After a period of use, many bacteria will also breed on the membrane cloth. Therefore, to address the disadvantage that turning on the humidifier will increase the air supply power, we have proposed a new humidification mechanism. Summary of the Invention

[0017] 2. By setting the swing bars on both sides of the gap between two adjacent membrane cloths, when the airflow passes through, due to the pressure difference, the two swing bars that have absorbed water will continuously hit each other.

With the setting of the positioning rod and the side guard plate, the two water-absorbing membrane cloths 1 and 2 can be kept in a taut state. The size of the air outlet gap, that is, the gap between the two adjacent membrane cloths, can also be adjusted as needed. When the device does not need to humidify, the knob can be turned to pull apart the two two-way sliding parts close together, that is, the two tightened inner positioning steel wires at the air outlet gap, thereby exposing a larger air outlet gap for rapid airflow. The rapidly passing airflow can also more easily take away the dust stuck on the surface of the water-absorbing membrane cloth 1 and the water-absorbing membrane cloth 2, ensuring that the water-absorbing membrane cloth 1 and the water-absorbing membrane cloth 2 remain clean.
