JAUE2022-106: Energy Efficiency and the MCP Reinforcement in Disaster Base Hospitals

Abstract

As hospitals are energy-intensive facilities, establishing a medical continuity plan (MCP) is important to save energy and prepare for disasters. Introducing a heat recovery heat pump (HP) as a measure for energy conservation has been confirmed to effectively save energy in heat source systems based on estimated heat load values. However, few hospital facilities have incorporated the HP into their process; therefore, the effectiveness of this heat recovery system must be further promoted and verified using actual heat load. In this paper, we report the effects of introducing the heat recovery HP to a hospital facility in Sagamihara City, Kanagawa Prefecture, Japan, by analyzing the actual operational data and simulating the system using the actual heat load. The results showed that the studied hospital achieved a well-balanced heat load of cold and hot water throughout the year by installing the heat recovery HP, with improved annual energy savings (approximately 27.5%) and system efficiency (approximately 1.38 times) compared to the present system without HP. The simulation analysis verified the effectiveness of the heat proposed system
