Description

Technical Field

[0001] The utility model relates to the field of air conditioning systems, in particular to an adjustable air volume type elevated floor laboratory air conditioning system. Background Art

[0002] In the current air-conditioning system of cleanroom laboratories, it is required that supply air, return air, fresh air and exhaust air are all delivered in a certain proportion to meet the requirements of ventilation frequency and pressure difference. However, the working conditions of laboratories are different. These air volumes can usually be controlled by frequency conversion to meet energy-saving requirements. At present, cleanroom laboratories require the use of elevated floors to achieve uniform air volume. In this system, especially in the mode of fresh air (no return air or a small proportion of return air), the elevated floor is generally opened evenly to form a static pressure cavity under the floor, and then exhausted through the cavity (a small amount of return air, for cost considerations, generally does not pass through pipes, but enters the air-conditioning unit directly through the floor cavity through negative pressure).

[0003] However, most of the current raised floor laboratory air conditioning systems have the following problems:

[0004] The existing elevated floor laboratory air conditioning system, when conducting operating experiments in the laboratory, mostly controls and adjusts the internal temperature through the air conditioning system. However, when performing wind transmission temperature control, the exhaust or return air is uncontrolled or difficult to control, resulting in an increase in the air supply volume and waste of energy. In severe cases, it may also affect the debugging of the laboratory air volume and pressure gradient, making it inconvenient to control and adjust the wind force delivered by the air conditioner. At the same time, when the air conditioner is delivering wind, the gas is mostly directly diffused into the laboratory, and the warm or cold air blown out is easily exhausted quickly from the room, resulting in energy waste and inconvenience for convenient energy reflux utilization.

[0005] Improvements should be made to the above disadvantages, and an adjustable air volume raised floor laboratory air conditioning system is proposed. Utility Model Content

[0046] Specifically, when using this adjustable air volume raised floor laboratory air conditioning system: Figure 1-11When the temperature inside the wall 5 is adjusted, the air-conditioning device body 1 can be controlled. The air-conditioning device body 1 controls the temperature of the absorbed wind through the fresh air duct 2, and then delivers the warm air or cold air to the air distribution box 8 on the air supply port 7 through the air delivery box 4. The wind is evenly delivered through the first air outlet 17 on the air distribution box 8 and the first air outlet 17 on the first wind shield 15 to adjust the temperature inside the wall 5. At the same time, the temperature sensor module 6 in the wall 5 is used for detection and control.
