A Preliminary Design,Economic and Energy Analysis,and Environmental Impact Assessment for a Seawater Cooling Project Naval Security Group Facilities at Winter Harbor,Maine.

摘要

Preliminary design and analysis were performed for a proposed seawater air conditioning system for an existing U.S. Navy building at Corea, Maine. Two major options were examined. The first, to use seawater for the entire cooling load (100 tons); the second, to use additional cooling and dehumidification (enhancement) if necessary, when the seawater temperature is too high. A number of alternate enhancement methods were examined, and preliminary designs developed, including one for a solar/desiccant drying system. The existing air conditioning system was also considered for use for enhancement, if desired. The initial costs would be lower than for a new enhancement system; however, life cycle costs for this option would be higher due to greater energy use. The life cycle costs for the seawater system are lower than for a conventional system. If the seawater system can be used without enhancement, it can save 87% of the electrical energy used for air conditioning. With enhancement it can save 68% of the electrical energy. No significant long-term adverse environmental impacts are foreseen. Minor temporary disturbance of the site will occur during construction. (Author)
