R744.com: ATMO Europe: Unorthodox AHU with Reversible CO2 Heat Pump Under Development for European Offices

Danish Technology Institute presenting case study on HVAC&R technologies at ATMO Conference, networking event about natural refrigerants

Danish manufacturer Unic Air has partnered with the Danish Technology Institute (DTI) and other stakeholders to develop an air handling unit (AHU) with a reversible CO(R744) heat pump, according to Christian Heerup, Senior Consultant at DTI.

A prototype of the unorthodox system, dubbed HVACO2, is currently being developed by the manufacturer, with a plan to install the unit at a Danish office building by the end of 2023 for real-world testing and demonstration, he explained.

To date, the concept has been lab tested for performance, efficiency and reliability.

Heerup introduced the HVACO2 during his presentation in a heat pump session at the ATMOsphere (ATMO) Europe Summit on natural refrigerants. The conference took place last November in Brussels and was organized by ATMOsphere, publisher of R744.com.
