Use of the Building Loads Analysis and System Thermodynamics Program to Perform Total Energy System Analysis.

摘要

This report describes a systematic procedure for applying the Building Loads Analysis and System Thermodynamics (BLAST) computer program to perform energy and life-cycle cost analyses of conventional, total energy, and selective energy systems as they might be applied to meet the energy demands of buildings or groups of buildings. The iterative application of this computer tool to permit the selection of nearly optimal candidate systems is described, and use of the program to estimate the performance of specific components during final plant design is outlined. The BLAST program and methods for its effective use are designed to support the engineering efforts required to implement guidance issued by the Office of the Chief of Engineers (Engineering Instructions for Preparation of Feasibility Studies for Total Energy, Selective Energy, and Heat Pump Systems, 1 July 1975). In addition to the prediction of space energy demand and the simulation of various air distribution systems, the BLAST program can simulate the performance of central energy supply systems consisting of any or all of the following components: diesel engine generators, gas turbine generators, steam turbine generators, centrifugal or reciprocator chillers, absorption chillers, double-bundle chillers (heat pumps), boilers, solar collectors, hot thermal energy storage, cold thermal energy storage, and utility company power.
