The Analysis Of Designation Of The Central Air Conditioning System For A Commercial Center And Energy Saving Measures

In China,the vast majority of commercial centers are equipped with central air conditioning,whose overall energy consumption accounts for as much as 50% of the total energy consumption of shopping malls.Obviously,in order to really reduce the energy consumption of commercial centers and reduce their operating burden,it is necessary to tap the energy-saving potential of central air conditioning.Business centers are very common and common in China.If the energy consumption of central air conditioning can be controlled within a certain range,it will obviously help to alleviate the energy shortage in China.How to overcome this problem is also being explored by academic circles.This paper mainly outlines the measures and research related to energy saving of air conditioning in commercial centers abroad,and chooses an air conditioning project in an entity commercial center as an example to study how to regulate and control the energy consumption of air conditioning system.At the same time,based on the air-conditioning project,the author designs the central air-conditioning system as a whole,and puts forward energy-saving improvement measures.This paper reviews the status quo of central air conditioning in commercial centers and the research progress of energy saving by investigating domestic and foreign literatures.Using case analysis method,the central air conditioning system of a commercial center is taken as the research object and calculated,mainly using two calculation methods of air conditioning wet load and cold load.Through load calculation,considering the real situation of the commercial center,the air conditioning system design scheme is compiled,and then the economy of the scheme is analyzed.The energy consumption of air-conditioning system and its composition are discussed,and energy-saving suggestions are put forward based on this.The research conclusion shows that the energy consumption of air conditioning system installed in shopping malls can be optimized and improved from many aspects,such as: accurately calculating load with advanced algorithm,selecting cold sourceform according to building conditions,selecting equipment with superior efficiency according to demand in the process of equipment selection,and adopting energy saving in the process of system operation.Management measures,build and improve the system and strengthen management,do a good job of system maintenance,improve the efficiency of system operation and extend the service life of the system.
