Everything shaping
the world of cooling.
Technology, companies and events worldwide
Everest Refrigeration and Embraco have introduced the Plus Inverter+, the first water purifier in Brazil to use inverter compressor technology. Built around a sealed unit with Embraco's FMS variable-speed compressor and R600a refrigerant, the product cuts energy consumption by 70% compared to Everest's conventional Plus line.
A new round of HVACR price increases takes effect in November 2026, with disclosed increases ranging from 3% to 15% across at least eleven manufacturers. Most adjustments are effective November 1–2, while two additional increases are scheduled for mid- and late-month.
As inverter-driven and cold-climate heat pumps hold capacity into single-digit outdoor temperatures, manufacturers say the gas-furnace switchover point in dual-fuel systems must be set per application rather than by a universal rule. Daikin, Midea, Lennox, and Rheem outline how replacement cycles, evolving controls, and local utility economics are reshaping how contractors design and sell these systems.
Cooling towers reject excess heat through evaporative water cooling — a principle used in industry for over 100 years. The review covers construction and operating cycle, four main types by air delivery method, key parameters (approximately 1% evaporation per 7 °C of cooling), and Legionella protection measures, including mandatory drain eliminator replacement per UNE 100030/2017.
France's Ministry of Foreign Affairs links cyberattacks on refrigeration systems to the Iranian Revolutionary Guards. A TÜV Nord expert recommends assessing the need for refrigeration system protection based on potential consequences for technological processes.
Chinese thermal management manufacturer Tongfei has signed a long-term partnership agreement with Canadian CES Corporation in the field of data center liquid cooling. The partnership provides access to North American projects through Intelliflex's modular infrastructure, though specific products, order volumes, and delivery schedules have not yet been disclosed.
SHARC Energy has received a $5 million purchase order from the City of Surrey for a district energy plant that recovers heat from Metro Vancouver's regional sewer system. Built around the SHARC 800 system, the facility is designed for an initial 6 MW thermal capacity with phased expansion to approximately 27 MW.
South Sudan ratified the Kigali Amendment on 23 October 2026, becoming the 176th country to do so. As a Group 1, Article 5 party, it must freeze HFC production and cut HFC consumption by 80% by 2045, while also reducing HCFC use by 65% against its 2009–2010 baseline.
A complete heat exchanger specification must address physical arrangement, mechanical integrity, pressure compliance, maintainability, and instrumentation—not just thermal duty. Overlooking these interface details can turn a correctly selected unit into an expensive installation or operational problem.
Eugene le Roux (FSAIRAC) and Eamonn Ryan argue that a heat exchanger specification should be built around functional parameters—fluid properties, temperatures, thermal duty, and pressure conditions—rather than physical characteristics alone. Published in RACA Journal, this Part 1 of a two-part series covers the functional side; Part 2 will address the physical interface, mechanical integrity, safety, maintenance, and instrumentation.
Psychrometric analysis links relative humidity to condensation, corrosion, and drying, but engineers must account for temperature, airflow, surface properties, and contaminants before drawing conclusions. A single RH reading is never sufficient on its own.
The effect of relative humidity on cooling equipment varies fundamentally between evaporative and conventional air-cooled systems. For evaporative coolers, dry air maximizes performance, while conventional condensers are rated primarily on dry-bulb temperature and airflow. Engineers should apply manufacturer-specified rating conditions and correction methods rather than assume a universal humidity effect.
