Al-Galala Resort District Cooling Plant

This project was undertaken by a consortium comprising ECG Engineering Consultants Group, Misr Engineering Development Company (MEDCOM), and ECM Energy Services.
The district cooling plant consists of a ground floor and a mezzanine, with a total built-up area of about 3,500 m2.
The plant, operated using chilled water, has a total cooling capacity of 16,866 kW (4,800 TR).
It includes the following components:
• double-height chiller yard complete with chillers, pumps, piping, and connections
• administration area that includes oices, meeting room, toilets, storage area, and other services
• electrical rooms with low-voltage and medium-voltage generators
The plant has four centrifugal, water-cooled, parallel counterflow chillers, as well as HFC-134a refrigerants. The chillers utilize the vapor-compression cycle, and each chiller has a capacity of 2 × 5,622 kW (2 × 1,600 TR) at a constant speed, and a capacity of 2 × 2,811 kW (2 × 800 TR) at a variable speed.
