How to ensure strict requirements for temperature and humidity control accuracy in scenarios with no or low heat sources?

Laboratories, museums, and testing rooms are equipped with a large number of professional equipment, which have extraordinary strict requirements for temperature and humidity accuracy, and require facilities specialized in high-precision scenarios and precision control to provide guarantees.

 

 

With the development of Industry 4.0, industrial scenarios such as laboratories, testing rooms, and equipment rooms continue to emerge. To ensure that these scenarios remain online, critical infrastructure has become an indispensable and important application.

 

Laboratories, museums, and testing rooms are equipped with a large number of professional equipment, which have extraordinary strict requirements for temperature and humidity accuracy, and require facilities specialized in high-precision scenarios and precision control to provide guarantees.

 

 

Taking laboratories as an example, common ones include laboratories in various industries such as high-end manufacturing, automotive manufacturing, optics, nanomaterials, communication, and semiconductors. The reliability of these laboratory test results depends not only on whether the experimental process is in compliance with regulations, but also on whether the laboratory environment is well controlled.

 

If the humidity is too high, it is easy to cause corrosion of circuit components, form local short circuits, and cause atomization and accelerated aging of optical components. If the temperature is too high, it will cause the lubricating oil of the instrument to accelerate aging, leading to severe wear and tear; At the same time, it may also cause an increase in the resistance value in the circuit, causing high voltage in the equipment and shortening the service life of the instrument. So, how to establish a constant temperature and humidity environment for these laboratories?

 

In response to the special needs of laboratories in various industries such as high-end manufacturing, automotive manufacturing, optics, nanomaterials, communication, and semiconductors, Vertiv Technology (NYSE: VRT) has launched——

 

Vertiv Liebert LPC

Constant Temperature and Humidity Precision Air Conditioning

 

1. Professional adaptation: No heat source, high precision

 

Vertiv Liebert LPC constant temperature and humidity precision air conditioner is a product developed specifically for scenarios without heat sources or low heat loads, with cooling, heating, humidification, and dehumidification functions. The product adopts a system level high reliability design, and the entire machine adopts high-quality components that have been strictly certified. Based on advanced control systems, stable operation is guaranteed. At the same time, the product has fault self diagnosis function and multiple protection measures, ensuring that the equipment has an industrial grade design service life on the basis of achieving uninterrupted operation throughout the year.

 

2. Full frequency conversion control: eliminating steady-state errors

 

Due to the high requirements for environmental conditions in application scenarios, the temperature and humidity control accuracy of precision air conditioners with constant temperature and humidity is the core indicator for measuring the performance and quality of air conditioners. Striving for precision in control, the first challenge in precision control is frequency conversion control technology.

 

Difficulty 1: Variable frequency control technology

 

The Vertiv Liebert LPC constant temperature and humidity precision air conditioner adopts a self-developed professional controller with multiple built-in control logics, which is suitable for complex scene requirements. The main components all adopt frequency conversion control technology, achieving full frequency conversion design, which helps to achieve temperature control accuracy of up to ± 0.3 ℃ and humidity control accuracy of up to ± 1.5%.

 

Difficulty 2: Reducing steady-state error

 

The control logic used in traditional air conditioning equipment inevitably leads to a certain deviation between the actual value and the set value during the actual operation of the air conditioning system, even if the temperature and humidity reach a stable state.

 

And Vertiv Liebert The PC constant temperature and humidity precision air conditioner adopts proportional integral derivative (PID) control, which enables the system to converge in the temperature and humidity curve and significantly reduce steady-state errors after entering steady state. That is, the deviation between the actual temperature and humidity values and the set values approaches zero after stabilization, achieving higher control accuracy.

 

3. Green and energy-saving: low noise and cleanliness

 

In production and storage environments such as biopharmaceuticals, papermaking, tobacco, textiles, etc., dust and particulate matter in the air can greatly affect equipment operation or material quality. In response to this issue, Vertiv Liebert LPC constant temperature and humidity precision air conditioning products come standard with air filters, and filtration levels can be selected according to scene requirements to meet the strict environmental requirements for cleanliness.

 

 

In summary, VertivTM Liebert ® LPC constant temperature and humidity precision air conditioning integrates multiple advanced technologies, based on first-class performance quality, and can be widely used in pan industrial scenarios without or with low heat sources, providing high-quality temperature and humidity environments.
