Description

Technical Field

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

[0002] Nowadays, the requirements for temperature and humidity in fields such as laboratories, the pharmaceutical industry, and industrial production are gradually increasing. Many industries have strict requirements for 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. Excessive or too low humidity may affect the performance of electronic components or cause equipment failures.

[0003] Most of the existing constant temperature and humidity air conditioning units use membrane humidifiers for humidification. The working principle of the membrane humidifier is to utilize the ultra-fine pores of the membrane cloth to make water 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, thus achieving the humidification effect. However, this humidification method requires the air flow to completely pass through the multi-layer wet membrane cloth before entering the ventilation duct. Therefore, once the humidifier is turned on, the wind power 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 the membrane cloth more likely to adhere to the floating dust in the air. After using it for a period of time, a lot of bacteria will also grow on the membrane cloth. Therefore, in view of the drawback that the air supply power increases when the humidifier is turned on, we propose a new type of humidification mechanism. Summary of the Invention

Between the tops of the two side guard plates, there is fixed the same upward-opening rectangular box-shaped temporary water accumulation frame. A rectangular hole matching the shape of the temporary water accumulation frame is opened at the top of the unit housing, and the temporary water accumulation frame, the bottom water storage tank and the two side guard plates block the longitudinal section of the unit housing to ensure that the air flow can only flow through between the two side guard plates. And at the bottom of the temporary water accumulation frame, there are membrane cloth perforations integrally connected in a "zigzag" structure. Two symmetrically arranged vertically drooping water absorption membrane cloths one are inserted into the two hole positions near the middle of the membrane cloth perforations, and two water absorption membrane cloths two are inserted into the membrane cloth perforations near both sides and are vertically drooping.

[0010] Preferably, the tops of the water-absorbent membrane cloth one and the water-absorbent membrane cloth two are both provided with equally spaced positioning convex cloths, and a top cover is fixed to the top of the temporary water accumulation frame.

Blocks are fixed at both ends of the grooved clamping rails, and return springs are fixed between the blocks and the surface of the sealing baffle, which can tightly press the filter cloth clamping frame fixed with the air filter cloth on the surface of the sealing baffle during use.

[0014] The beneficial effects of the present invention are as follows: 1. By arranging the first water absorption film cloth and the second water absorption film cloth in a flared shape below the temporary water accumulation frame, not only can the air flow quickly pass through the flared opening and carry away the water vapor on the surfaces of the first water absorption film cloth or the second water absorption film cloth on both sides during ventilation, but also the air flow can quickly and easily pass through the gap between the two adjacent film cloths, avoiding the traditional need for pressurization and acceleration to penetrate through multiple layers of film cloths, greatly reducing the wind resistance, and this method also avoids the possibility of forcibly intercepting floating dust in the air, making the film cloth cleaner.

[0015] 2. By arranging the swing bars on both sides of the gap between the two adjacent film cloths, when the air flow passes through, due to the air pressure difference, the two water-absorbed swing bars will continuously strike each other, and with the passage of the air flow, more water vapor adsorbed on their surfaces can be taken away faster.

[0016] 3. Through the provided air volume adjustment mechanism, all the inner positioning steel wires can be tightened. In combination with the settings of the positioning rod and the side guard plates, the two water absorption fabric sheets I and the two water absorption fabric sheets II can be kept in a taut state, and the size of the air outlet gap, i.e., the gap between the two adjacent fabric sheets, can also be adjusted as needed. When the device does not need to humidify, the knob can be rotated to separate the two bidirectional sliding members that are close to each other, i.e., the two tightened inner positioning steel wires at the air outlet gap, thereby exposing a larger air outlet gap for the air to pass through quickly. The quickly passing air can more easily carry away the floating dust adhering to the surfaces of the water absorption fabric sheet I and the water absorption fabric sheet II, ensuring that the water absorption fabric sheet I and the water absorption fabric sheet II remain clean.

The space between the partition frame one 6 and the partition frame two 18 is a humidifying space. A centrifugal fan 5 is arranged on the side of the partition frame one 6 away from the evaporator module 9. It is characterized in that a bottom water storage tank 12 with an upward-opening rectangular box-like structure is embedded between the partition frame two 18 and the partition frame one 6 at the bottom of the unit outer cover 1. At the top of the bottom water storage tank 12, side guard plates 26 with the same height are fixed at the opposite two side edges, and the side guard plates 26 are closely attached to the front and rear inner walls of the unit outer cover 1. A same upward-opening rectangular box-like structure temporary water accumulation frame 2 is fixed between the tops of the two side guard plates 26.

The temporary water accumulation frame 2, the bottom water storage tank 12, and the two side guard plates 26 block the longitudinal section of the unit outer cover 1, ensuring that the air flow can only pass through between the two side guard plates 26. And a film cloth perforation 202 with an overall "zigzag" structure is opened at the bottom of the temporary water accumulation frame 2. Two symmetrically vertical and downwardly hanging water absorption film cloths one 16 are inserted into the two hole positions near the middle of the film cloth perforation 202, and two water absorption film cloths two 23 are inserted into the film cloth perforation 202 near the two sides.

The deepest part of the fan-shaped water accumulation tank 13 is located at the bottom end of the water extraction pipe 404. By setting the fan-shaped water accumulation tank 13, the phenomenon of air extraction by the external water pump 401 can be prevented, and it is possible to ensure that when the water level inspection is abnormal, the external water pump 401 can persist for a longer time to ensure that the two swing bars 29 are always in a soaked state.

[0028] Refer to Figure 1 , Figures 3-4 , air outlet holes 103 and air return openings 11 are respectively reserved near both ends of the upper surface of the unit housing 1, and an air outlet pipe 501 adapted to the size of the air outlet hole 103 is fixed at the air outlet of the centrifugal fan 5; an electric heater 21 is arranged at the air inlet of the centrifugal fan 5, and an observation round hole 104 is opened on the front surface of the unit housing 1 near the electric heater 21.

[0030] Working principle: When this device is in use, the air outlet pipe 501 and the air return port 11 are connected to the room to be adjusted through a sealed pipeline. When it is necessary to adjust the temperature and humidity of a room with high temperature and high humidity, the external unit compressor controls the evaporator module 9 to cool down. At the same time, through the set air volume adjustment mechanism 7, when the device does not need to humidify, the knob 702 can be rotated to separate the two bidirectional sliding members 704 that are closely adjacent to each other, that is, the two tensioned internal positioning wires 24 at the air outlet gap, thereby exposing a larger air outlet gap for the air flow to pass through quickly. Then, the electric heater 21 at the inlet of the centrifugal fan 5 is turned on to dehumidify the air. In winter, the temperature in the room is low and the humidity is low. At this time, the external unit compressor is controlled to start, and the air passing through the evaporator module 9 is heated. At this time, the humidifying mechanism 4 is started, that is, the external water pump 401 is started, and the air outlet gap of the water absorption membrane cloth one 16 and the water absorption membrane cloth two 23 is sprayed and humidified, and the air outlet gap is adjusted to be reduced. At this time, through the water absorption membrane cloth one 16 and the water absorption membrane cloth two 23 arranged in a flared shape below the temporary water accumulation frame 2, the air flow can quickly pass through the flared opening and carry away the water vapor on the surfaces of the two water absorption membrane cloth one 16 or the water absorption membrane cloth two 23 on both sides. Moreover, the air flow can quickly and easily pass through the gap between the two adjacent membranes. And when the air flow passes through the gap between the two swing bars 29, due to the air pressure difference, the two water-absorbed swing bars 29 will continuously hit each other, and with the passing of the air flow, more water vapor adsorbed on their surfaces can be carried away faster.

[0031] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
