Building-type combined cooling heating and power system power device selection method

Abstract

The present invention discloses a building-type combined cooling heating and power system power device selection method. The method comprises the steps of carrying out dynamic simulation of cooling and heating loads on a target building by using a building CAD drawing in Dest software, thus to obtain full-year cooling and heating load requirements; calculating cooling and heating average daily loads, thus to calculate economic cost and primary energy consumption; calculating average days of a cooling season and a heating season individually, and multiplying the cooling and heating average daily loads by the corresponding days, thus to obtain full-year operation energy consumption and cost situations; and calculating system performance evaluation indexes to different schemes, and determining an ultimate installation model selection result according to performance evaluation optimization. The method is simple, rapid, good in accuracy and capable of comprehensively considering factors at multiple respects; the method can serve as a supplement for a selection method of ordering power by heat; and the method is applicable to a building-type combined cooling heating and power system and also applicable to a regional-type combined cooling heating and power system.

Description

technical field [0001] The invention belongs to the technical field of design energy, and in particular relates to a method for selecting a power device of a building-type combined cooling, heating and power supply system. Background technique [0002] In today's increasingly scarce resources, sustainable development has long been a topic of concern to the world. Energy issues are not only the pillar of a country's national economic development, but also an important part of sustainable development. Therefore, it is an important task to effectively improve energy utilization and reduce pollutant emissions during utilization. The traditional power supply is monopolized by the power grid. Power supply, gas supply, and heating are planned separately and have their own networks. This will make it difficult to supply the energy demand of industries and buildings in a timely manner. Especially in summer or winter, the use of air conditioners is very large. Civilian air conditione...

Problems solved by technology

Generally speaking, the method of thermal power selection has a higher energy utilization rate, so that the installed capacity can be initially selected, but it is not necessarily the first choice after the calculation of various indicators. At the same time, for the same total capacity, there are many There are different capacity combinations, and there are differences between different combinations
