Court order
An East London Crown Court faced significant challenges with its outdated and inefficient air conditioning system that consisted of two large old chiller units.
The 200-year-old listed building required a more sustainable and energy efficient solution. Sub-Cool FM specified five Panasonic 170kW ECOi-W R32 air source heat pump units that operate in cascade.
The project delivered a modern, sustainable solution that overcame historic infrastructure constraints, improved energy efficiency by 50% and ensured long-term reliability for this important civic site. The Crown Court’s original air conditioning system was not only inefficient but also difficult to upgrade due to the building’s listed status and the age of its pipework. This increased the risk of corrosion and leaks, while water quality issues further threatened the longevity of any new system.
Installer Sub-Cool FM specified the five 170kW Panasonic ECOi-W R32 units, chosen for their high energy efficiency, modular and compact design and reduced environmental impact. To address the risk of corrosion in the pipes and the substandard water quality, hydraulic separators were installed for the secondary circuit, paired with a plate heat exchanger to protect the new equipment and extend its lifespan.
