THE USE OF COGENERATION SYSTEMS IN A HOSPITIALITY PROJECT

摘要

Combined heat and power (CHP) systems are finding applications in commercial facilities through energy efficiency, reliability, and return on investment. CHP equipment can be a key element in a micro-grid for a facility or group of buildings in close proximity. The characteristics of a micro-grid system include energy generating equipment directly serving consuming equipment through on-site electrical distribution system. The robust nature of the on-site generating equipment typically determines if supplement energy from a grid source is required. Other examples of energy generating equipment found in micro-grids include generators, fuel cells, batteries, and renewables. The increasing use of micro-grids in the built environment can be attributed to the advancement of cogenerating technologies like CHP. CHP equipment is available in many sizes and design variations, but the premise amongst these features is the same. A fuel source is consumed by the CHP equipment and produces electricity and thermal energy. The most common fuel source used by CHP systems is natural gas. The most common product of a CHP system is electricity and hot water. The paper will summarize the application of a CHP in a hospitality project. The discussion will focus on the strategy for designing the system and applying different types of cogeneration equipment. There will be a comparison of the performance of the CHP system compared to the performance of the traditional equipment. There will also be a study to show the benefit of producing electricity on-site avoiding the losses associated the with transmission of the power.
