The work of preparing International Stand

15、ards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also ta

16、ke part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees i

17、s to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibili

18、ty that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

19、10 All rights reserved 1Cogeneration systems Technical declarations for planning, evaluation and procurement 1 Scope This International Standard describes the technical declarations for a cogeneration system (CGS) that simultaneously supplies electric power and heating and/or cooling, for planning,

20、evaluation and procurement. It applies to the identification of investigation items for project evaluation, CGS evaluation, and primary information works for CGS procurement. It also specifies necessary check items in CGS planning, provides a procedure to obtain the satisfactory configuration of the

21、 CGS for each project, and includes a detailed process diagram of the key development steps. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edit

22、ion of the referenced document (including any amendments) applies.

The payback-period method is recommended only as a second

32、ary method of measuring investment worth. In particular, it is suggested that the payback-period method be used in addition to a method based on the time value of money. 3.14 reliability share of the time outside of planned maintenance and other planned shut-downs that the CGS can produce electric p

35、therefore, the project risk NOTE The testing process for any item under evaluation establishes whether or not the final conclusion is sensitive to a change in assumption. The variables subjected to sensitivity analysis will usually include capital costs, overall conversion efficiency, completion tim

36、e, fuel costs and the escalation of costs. 3.17 system design design of the CGS 4 Key project information and analysis for evaluation 4.1 General In order to carry out the proper evaluation of the CGS, the following items shall be accurately analysed at each stage of the investigation. The important

37、 investigation items are listed in 4.2 through 4.4, and descriptions on detailed parameters are provided. Items included in this category should basically be provided by the purchaser. 4.2 Site conditions and energy demands 4.2.1 Site conditions The purchaser of a CGS shall identify the installation

38、 site and related conditions necessary for the planning of the CGS. The following environmental conditions and various regulatory requirements which may affect the planning of the CGS shall be considered: weather conditions, average and maximum (predominant wind direction, wind speed, precipitation

39、of rain and snow, etc.); general air quality (industrial emissions, sand, salt, soil, pollen, etc.); BS ISO 26382:2010ISO 26382:2010(E) 4 ISO 2010 All rights reserved ambient conditions (temperature, pressure and humidity) including annual averages, maximum and minimum conditions; water supply tempe

40、rature, its quality and quantity (hot-water supply, cooling water, de-mineralised water, water processing, etc.); land-use classification (business district, rural area, etc.); environmental air and effluent emission regulations (CO, CO2, NOX, SOX, particulate matters, unburned hydrocarbon, visible

41、smoke, cooling tower plume, etc.); regulations for vibration and noise (influence on neighbourhood); input fuel type of fuel, specific energy, chemical composition, temperature (maximum and minimum), pressure (maximum and minimum), other properties; installation site (indoor, outdoor, seismic zone,

42、site history, load-bearing capacity of soil, ground water level, frost line, snow load, sandstorms, transportation conditions, grid voltage, regulations for health and safety, etc.). 4.2.2 Energy demands 4.2.2.1 Investigation items for specifying energy demand Maximum and minimum values, as well as

43、data about variations in energy demand, shall be investigated carefully by the purchaser, including the demands for electric power and heating and/or cooling. The following conditions related to energy demands shall also be clarified: electric power demand and voltage, frequency and power factor to

44、be delivered; restrictions from the electrical grid, maximum power output, frequency variations, etc.; thermal demand, flow rate, pressure, temperature and quality requirements for heating and/or cooling to be delivered and to be returned; electrical and/or thermal load profile over a weekday and a

45、weekend day (24 hours) allowing for process or seasonal demand variation. 4.2.2.2 Investigation of energy demand pattern When a CGS is installed at a given site, it is important to identify the site classification because requirements for electric power and heating and/or cooling differ among variou

46、s types of sites. Typical types of facilities are as follows: office; hotel (resort, city, business, etc.); hospital (general, independent, etc.); store (retail, restaurant, department, supermarket, etc.); public site (government, hall, library, museum, etc.); sport, health or leisure facilities (sw

47、imming pool, gym, aquarium, etc.); computer centre; BS ISO 26382:2010ISO 26382:2010(E) ISO 2010 All rights reserved 5 residence (apartment, detached house, etc.); welfare facility; educational institution (university, elementary or junior/senior high schools, etc.); compound facility (integrated bui

48、lding including different categories); district heating and/or cooling facility (facility which supplies heating and/or cooling to buildings located in a district); industrial factory (food, chemical and pharmaceutical machinery, electrical equipment, iron and metal, textile, pulp and paper, gas/oil

49、 and/or other energy, glass soda and ceramics, etc.). If the facility is a building, it is important to know the total floor space, number of floors, area classification for each usage, and both the total area and the lay-down areas which are available during the construction. 4.3 Related policies and regulations Related government policies and regulations, both local and national, are applicable to the installation of a CGS. A detailed consideration of such policies is
