In scenarios with no or low heat sources, how can we ensure strict requirements for temperature and humidity control accuracy?

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

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

Vertiv^TM Liebert^® LPC Constant Temperature and Humidity Precision Air Conditioner

It provides customers with better options and can create a reliable and suitable operating environment for these special scenarios.

1. Professional adaptation: no heat source and high precision

Vertiv^TM Liebert^® LPC constant temperature and humidity precision air conditioner is a product developed specifically for scenarios with no heat source or low heat load, with cooling, heating, humidification and dehumidification functions. The product adopts a system-level high-reliability design, and the whole machine uses strictly certified high-quality components, based on advanced control systems to ensure stable operation. At the same time, the product has a fault self-diagnosis function and multiple protection measures, which ensures 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: Eliminate steady-state errors

Since the application scenarios have very high requirements for environmental conditions, the temperature and humidity control accuracy of constant temperature and humidity precision air conditioners is the core indicator for measuring the performance quality of air conditioners. The control accuracy is constantly improved. In precision control, the first difficulty is the frequency conversion control technology.

Difficulty 1 Frequency conversion control technology

VertivTM Liebert® LPC constant temperature and humidity precision air conditioner adopts self-developed professional controller with built-in multiple control logics to adapt to complex scene requirements. The main components all adopt variable frequency control technology to achieve full variable frequency design.

The temperature control accuracy is up to ±0.3℃.

Humidity control accuracy is up to ±1.5%.

Difficulty 2: Reducing steady-state error

The control logic used by traditional air-conditioning equipment means that during the actual operation of the air-conditioning, even if the temperature and humidity reach a stable state, there will inevitably be a certain deviation between the actual value and the set value.

The proportional integral differential (PID) control adopted by the Vertiv^TM Liebert^® LPC constant temperature and humidity precision air conditioner allows the system to significantly reduce the steady-state error after the temperature and humidity curves converge and enter a steady state. That is, after stabilization, the deviation between the actual temperature and humidity values ​​and the set values ​​approaches zero, achieving higher control accuracy.

3. Green energy saving: low noise and cleanliness

In production and storage environments such as biopharmaceuticals, papermaking, tobacco, and textiles, dust and particulate matter in the air can greatly affect equipment operation or material quality. To address this problem, Vertiv^TM Liebert^® LPC constant temperature and humidity precision air conditioning products come standard with air filters, and you can also choose the filtration level according to the scene requirements to meet the strict requirements of the environment for cleanliness.

In summary, VertivTM Liebert® LPC constant temperature and humidity precision air conditioner integrates multiple advanced technologies and based on first-class performance quality, can be widely used in pan-industrial scenarios with no or low heat sources, providing them with a high-quality temperature and humidity environment.
