Refrigeration And Air Conditioning Technology Better Guide

Evaporators are increasingly treated with advanced hydrophilic and antimicrobial coatings. Hydrophilic coatings reduce the surface tension of condensing moisture, allowing water to shed rapidly. This minimizes the thermal resistance of water droplets and reduces frost formation rates, maintaining peak heat transfer efficiency over extended operational hours. 5. Electrification and Thermal Energy Storage

Real-world examples abound. LG's Multi V i commercial HVAC solution, launched in 2025, is equipped with an advanced AI engine that collects real-time data on indoor temperature, humidity, and set temperatures. Using advanced AI algorithms, it specifies a "Clustering" level for each indoor unit, automatically controlling operation mode, airflow, and other settings. After an initial comfort optimization period, it transitions to power-saving mode, preventing unnecessary energy usage.

To truly make refrigeration technology "better," it must be decoupled from the fossil-fuel grid. refrigeration and air conditioning technology better

The EU-funded HYDROCOOL project is developing a new technology using CO₂ hydraulic compression and expansion to boost cooling system performance. Preliminary studies indicate the potential to nearly double the Coefficient of Performance through isothermal compression using liquid piston fluid and energy recovery between expander and compressor. This approach can significantly improve system lifespan and operating cost while displacing environmentally harmful HFCs.

According to José María Zarzuela Fernández, president of AEDICI, air conditioning and refrigeration installations are now "tending towards digitalisation, energy efficiency, sustainability, decarbonisation of buildings and integration with control systems". He specifically highlights real-time monitoring through advanced Building Management System platforms and digital twins, which allow optimization of operation from day one, as well as the use of artificial intelligence to adjust operating parameters based on the actual behavior of the building and outside climate. Using advanced AI algorithms, it specifies a "Clustering"

The intelligence is no longer confined to a central controller. The concept of distributed intelligence means that decision-making happens at every level, from the cloud down to individual devices themselves. This edge-based logic allows systems to make real-time decisions about asset protection and stability, enhancing reliability.

This is by design—proactive rather than reactive. According to José María Zarzuela Fernández
