能源是发展生产力和提高人类生活水平的重要物质基础，能源的消耗水平在一定程度上能够反映社会生产力的发展水平，能源也是当今社会关注的焦点，能源的日益紧张使得节能受到很多国家的重视，高低温试验机耗电量大，每年在10亿度以上，所以如何减少高低温试验机能耗备受人们关注。高低温试验机系统设计往往选用设计zui大负荷甚至预留一部分“裕量”，而实际运行中，工作条件往往不断变化，这就造成在实际系统运行中制冷系统所供冷量与高低温试验机所需不相匹配的现象，本文就重庆某运行中的高低温试验机为例，通过对运行参数的测量来分析系统匹配问题，并分析高低温试验机系统运行中的节能途径。energy is the development of productive forces and raise the level of human life important material base of energy consumption level to a certain extent, can reflect the development level of social productivity, energy is also a focus of attention in today's society, the growing tension of energy makes the energy conservation has been popularized by many countries, power consumption, high and low temperature testing machine every year above 1 billion degrees, so how to reduce the energy consumption of high and low temperature testing machine's widely attention. high and low temperature testing machine system design tend to design even set aside part of margin, maximum load, the actual operation, the working conditions are constantly changing, this can make the actual amount in the operation of the refrigeration system and cooling system with the high and low temperature testing machine does not match the phenomenon, in this paper, the chongqing ? a running high and low temperature test
高低温试验机制冷设备及制冷系统分析：high and low temperature testing machine refrigeration equipment and refrigeration system analysis:
本实验高低温试验机为氨制冷系统，采用氨泵集中式供冷。高低温试验机由高温库及低温库组成，高温库房制冷系统的热负荷由6台单级压缩机负担，低温库制冷系统的热负荷由2台螺杆式压缩机负担，每次运行其中的一部分，剩下的作为备用机。系统有一台立式壳管式冷凝器，蒸发器为肋片管式蒸发器以及一些辅助设备组成。this experiment for ammonia refrigeration system, high and low temperature testing machine adopts centralized cooling ammonia pump. high and low temperature testing machine by high temperature and low temperature of library, the heat load of high temperature warehouse refrigeration system shall be borne by the 6 single stage compressor, the heat load of the refrigeration system of the low temperature shall be borne by the two screw compressor, each part of the operation, the remaining as the standby machine. system has a vertical shell and tube condenser, evaporator for finned tube evaporator and some auxiliary equipment.
