Baseline Information:
Under the global pressures of energy and climate change, achieving "carbon peak" and "carbon neutrality" has become a shared goal. The messages from the 2021 two sessions indicate that the next five years will see a significant focus on energy efficiency and carbon emission reduction. Central air conditioning systems, which account for 50%-60% of energy consumption in public buildings, have emerged as a key factor in achieving these goals. The HVAC sector, being a significant energy consumer, needs to adapt by using advanced R&D, installation, and control technologies to achieve efficient and eco-friendly solutions.

To actualize the goals of "carbon peak" and "carbon neutrality," Zhejiang Province has issued documents such as the "Implementation Opinions on Supporting Carbon Peak and Carbon Neutrality" and the "Implementation Opinions on Completely Implementing the New Development Concept and Promoting Carbon Peak and Carbon Neutrality." These documents emphasize the orderly transition to a green and low-carbon economy. In response, various areas in Zhejiang Province have embarked on innovative pilot projects to explore low-carbon and zero-carbon initiatives in diverse fields. This project aligns with Zhejiang Province's commitment to dual carbon construction and sustainability.

Main Problems:

1. Current State of Application: The fluctuating conditions of temperature and humidity throughout the year pose a challenge for efficient operation of constant temperature and humidity HVAC systems. Traditional systems often waste energy due to inefficient compensation mechanisms.
2. Industry Trends and Development: The demand for constant temperature and humidity HVAC systems is particularly significant in industries such as fiber optics, biopharmaceuticals, and semiconductors. However, challenges persist in achieving optimal energy efficiency and low carbon emissions.

Activities:
This project focuses on implementing a range of cutting-edge technologies such as variable air volume control, thermal-humidity separation, low dew point evaporation, condensation heat recovery, and simulation-based maintenance. It provides clients with a comprehensive service platform for real-time monitoring, analysis, interaction, visualization, and energy consumption monitoring. Through the integration of smart technologies, the project aims to establish an industrial energy-efficient HVAC system that operates efficiently and adapts to changing conditions.
