The air-conditioner with control meets the demands of people in terms of living in a comfortable space, and it also has great advantage of energy saving and lower electricity consumption. Air-conditioner achieves energy saving purpose by the use of compressor and orifice set which carry out energy adjustment on refrigerant system. This thesis designs a 0ptimization design of standing type air conditioner. It is suitable for a room which it is big space Firstly, the thesis explains the principle and the advantages of Air-conditioner, so that we can understand the properties of the Air-conditioner. After that, through the scheme introduction, difference forms of each part of refrigerant system are chosen which is prepare for the design of the project. Then, an appropriate compressor is designed through the thermodynamic calculation. On this basis, evaporator are calculated and designed which adapts to the compressor. The throttle mechanism is chosen from market products directly. At last, the overall system is designed to be reasonable and compact. Key-words: Structure ; Air-conditioner ; Split ; Evaporator 目 录 摘 要 I ABSTRACT II 1 绪 论 1 1.1 研究的目的和意义 1 1.2 产品设计的基本思路和基本手段
