Al-Galala Resort District Cooling Plant

Project Description

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 offices, 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.
