At the Corfu Museum of Asian Art there was a need to replace VRV Variable Air Conditioning Systems with R-22, due to lack of spare parts.
New systems require larger cross sections because of the refrigerant change. Pipelines replacement would lead to extensive building interventions, making it almost impossible
For the maintenance of the pipelines, a special External Replacement Unit with a network cleaning system has been selected, for which the manufacturer provides an operating guarantee and retains the old cooling pipes.
The replacement of the old system was accomplished by keeping the refrigerant piping, in accordance to the manufacturer’s instructions, by qualified technical personnel.
At the same time, Energy Analyzers and Real Time Energy Monitoring Software were installed to record the energy consumption of the new and an old analog power system.
