The Technical Economic And Applied Analysis Of Central Air Conditioning System For A Convention Center Building In Hengshui

With the development of the social economy, urban construction, and the rising of people’s living standards, the quality of life is getting attention. Air conditioning is widely used as indoor air quality improve device. Air conditioning energy consumption accounts for a large proportion of energy consumption in buildings. As environmental issues and energy crisis have become increasingly prominent, energy conservation has become an international hot topic, energy conservation of air conditioning system become areas that concern scholars.This thesis, taking a convention and exhibition center building in HengShui city as an object, analysis VRF air conditioning system and water source heat pump air conditioning system. In the first part of this thesis, the writer will introduce the project profile, calculates the dynamic load of air conditioning according to the specific parameter of the object. And in order to get the design day hourly load and all-year hourly load, hourly load simulation analysis of this building were carried out. Then, on the basis of the dynamic load, the writer will design VRF air conditioning system solution and water source heat pump air conditioning system solution. And compare one solution to the other.The technical economical comparison has been made to both solutions, and a detailed analysis has been made to calculate the cost of the two kinds of solutions of initial investment, the operating cost, energy consumption and environmental impact and so on.Economic analysis results show that the annual total cost of the water source heat pump air conditioning system is 295.9 thousand, saving 31.9% than VRF air conditioning system. The life cycle cost of water source heat pump air conditioning system is 3394 thousand, saving 19.4% than VRF air conditioning system.Energy consumption analysis results show that the annual energy consumption of the water source heat pump air conditioning system is 248273.9kW,saving 24.87% than VRF air conditioning system.Environmental impact assessment results of two air condition systems show that the annual pollutant emissions of the water source heat pump air conditioning system is less than VRF air conditioning system. It’s annual emissions of carbon dioxide is 24.9% less than VRF air conditioning system. Emission reduction effect is obvious.Therefore, considering application characteristics and technical economy analysis results, we can see that the water source heat pump air condition has more advantages than the other in this project. Besides, the applied analysis of water source heat pump air conditioning system and VRF air conditioning system in this Thesis can provide some useful reference for the analysis and project selection of air conditioning system in similar regions.
