Description
Hospitals are energy and carbon intensive, yet large shares of their thermal demand are rejected as waste heat. We evaluate a heat recovery retrofit for a Moroccan university hospital that captures compressor discharge heat from two chilled water plants to produce domestic hot water (DHW) and space heating. Using metered fuel consumption, nameplate data, and in situ measurements (including infrared thermography at compressor outlets and electrical power analysis), and designing plate heat exchangers to deliver 60°C hot water, we estimate recoverable capacities of 400 kW and 117 kW from the two chillers. The recovered heat fully meets annual DHW and space heating loads, displacing 2.1 MWhthermal per year of fuel (equivalent to 164 t of LPG per year), avoiding 563 t CO2 year, and yielding 1.97 million MAD per year in savings. A simple payback of 3 months highlights compressor heat recovery as a rapid, low cost decarbonization pathway for Moroccan hospitals.
