摘要
近20年来，制冷和空调技术得到了飞速的发展和广泛应用。从人们的日常生活到国民经济的各部门，从传统产业到高新技术产业，从国防科技到航空航天，到处都离不开制冷技术及其设备。
本文简单介绍单级蒸汽压缩式制冷循环性能测试实验台的设计中的几个问题：新型绿色制冷剂的使用，热力循环的计算，蒸发器和冷凝器的设计计算，制冷循环附件的选型，各种热工测量仪器的选型及安装使用要求，以及制冷技术的发展和展望。
本实验台选用最有前途的绿色制冷剂R134a，广东美芝制冷设备有限公司的全封闭压缩机，及各种性能优良的控制设备和热工测量仪器
制冷循环性能测试实验台的作用，顾名思义是用实验的方法去测试各种实际因素对循环的影响，以便更好的分析研究实际循环的各种不完善因素和应作出的改进。用本实验台能研究高压液体过冷、是否有回热、压缩机吸气过热（有用及无用过热）等因素对循环的影响

ABSTRACT
This article simply introduced the in design several questions: New green refrigerant use，the calculation of the thermodynamic energy circulation, evaporator and condenser computation，air-conditioner appendix choice, as well as heat pump room air-conditioner development and forecast.
The air conditioning is as the name suggests carries on the adjustment to the air parameter, in order to cause the environment to suit our request. With development of our country national economy and the improvement of the people's lives level，people's living conditions condition request also in gradually enhancement. Therefore the air conditioning holds the very important position in the daily life. Also causes the air conditioning technology in the unceasing enhancement, achieves the people to the environment request. The heat pump room air-conditioner both can make cold and heat, can satisfy the requests of the winter and summer, so it gets a fast development. The air-conditioner is facing the miniaturization, the energy conservation, the intellectualization, is artistic, the health direction develops.
In recent years, along with the housing condition change, some users stemming from saved spatial the consideration, started to purchase ＂one-drivers-two＂air-conditioners, the promotion pulls as soon as tows two air-conditioners the development and the improvement.
KEY WORDS The heat pump , One-drivers-two air-conditioner, New green refrigerant,
Energy conservation, Environmental protection
