A Review of the Key Points of the Combined Cooling, Heating and Power System Development for the Medical and Nursing Integrated Buildings

As global aging intensified, the institutions integrated the medical and old-age care came into being. Based on the review and analysis of the background and development trend, this study drew the conclusion that the energy co-supply system for the medical and nursing complex may face the problems of low thermal efficiency, serious residual heat waste, high carbon emission, and poor economy and stability. The design of the low-carbon energy co-supply system in the active and passive combined building complex was proposed based on the integration of solar energy, membrane distillation and Vehicle to Building (V2B) technology. A multi-level optimization model of the system was established and finally the system comprehensive performance was improved including the thermal efficiency, stability and economy. A multi-dimensional optimization model of the energy management mechanism of the new low-carbon co-supply system was proposed to achieve the multi-dimensional consistency evaluation of the system's energy management. This study will be a theoretical and practical innovation of the new co-supply system for medical and nursing buildings, and will realize the high energy efficiency operation, economic scheduling and energy cascade utilization of the combined cooling heating and power (CCHP) system for medical and nursing buildings under the concept of low carbon.
