Design and Operation Analysis of Multi-connected Split Air Conditioning System in an Office Building
In order to master the operation of multi-connectid split air conditioning system in office buildings,this paper takes an office building in Zhengzhou as the research object,introduces the design of multi-connectid split air conditioning system.Based on the intelligent operation platform,survey and testing data,the indoor temperature and relative humidity of typical rooms are analyzed,and the overall energy consumption,monthly energy consumption and typical daily energy consumption of the multi split air conditioning system are analyzed.The results show that part of the air conditioning system of the office building is not turned off after work.The typical room temperature in heating season is higher than the de-sign temperature.The annual energy consumption intensity of multi split air conditioning system is 35.64 kW·h/m2.The energy intensity has obvious seasonality,in heating season the outdoor tempera-ture and the energy intensity change greatly,in cooling season the outdoor temperature and the energy intensity change little.This study provides references for the popularization of multi-connectid split air conditioning system.
