A High-rise Office Building Air-conditioning Dynamic Load Calculation And Design Scheme Optimization Study In Hefei

Just the same as time, the pace of human social and economic development of the moment did not stop, but the cost of this rapid development is the growing energy consumption and building energy plays an important role in the overall energy consumption of the system, and building energy consumption must most of it is consumed in the air conditioning system to improve the living environment, the decisive factor in the size of the energy consumption of air conditioning systems is building air conditioning load size. To select HVAC design scheme is gradually becoming beholder wise see wisdom in the process, for an air-conditioning design projects, air conditioning system solutions are often not unique, but the air conditioning system plan will determine the initial investment and operating costs of the project. Therefore, comprehensive evaluation of the air conditioning system is particularly important.This paper reviews the current situation and the progress of energy saving work abroad, building air conditioning load calculation method development. Then a high-rise office building in Hefei, for example, the use of building thermal environment simulation software DeST of the high-rise office building was simulated hourly, completed a full year of dynamic load calculation, obtained by the office when the air conditioning load variation on equipment selection and system uptime control office building air conditioning systems and other aspects have some significance. At the same time the building has been the preferred paper studied air conditioning system solutions, comprehensive evaluation of the economy, value engineering principles and system satisfaction subjective and objective evaluation of the three to be selected conditioning program, where satisfaction evaluation system is simulated by DeST come, finally get a more reasonable conditioning program suitable for the building. This simulation analysis and evaluation methods to calculate the actual analysis of the combination can provide some reference for comprehensive evaluation of air-conditioning systems and preferred solutions.
