The Energy Consumption Analysis And Simulation Of Air Conditioning System In The Dynaminc Operation State

Air conditioning system is the main part of the building energy consumption, repre-senting about60%of the total building energy consumption,nowadays people pay moreattention to energy saving today,so building energy efficiency is more and more im-portant.Now part of the operation of the air conditioning system has a lot of problems,most of the time,the air conditioning system are in part load operation state, and part of theair conditioning load of the running state is not in the best condition, caused serious waste.this paper simulated the dynamic load of the air conditioning system operation, find thecontrol strategy of dynamic load of air conditioning system in the running state, so thatthe operation of the air conditioning system has been in a state of energy saving.This article mainly from the point of view of the air conditioning system dynamicoperation do the energy saving research. Using the Simulink toolbox of MATLAB soft-ware establish the physical model of each component of air conditioning system,and thenthe components connected constitute the whole air conditioning system model. Estab-lished four research variables and they are chilled water outlet temperature, cooling waterflow, cooling water inlet temperature, cooling water flow; Through the data that operationfrom the air conditioning system model to fit that energy consumption of air conditioningsystem with four variables function relation, and then to draw the constant load energyconsumption minimum with four variable value, and then calculate a few sets of data, andget conclusion that the dynamic load of the air conditioning system optimal operation stateis four variables with the load change input curve.Through the above research can be concluded that the dynamic load of the air condi-tioning system in optimal operation about energy saving30%, water chillers, cooling wa-ter pump, cooling water pump energy saving effect is remarkable. The results of the studyin this paper to practice the optimization of the air conditioning system operation has cer-tain reference value.
