随着经济建设的发展,及人民生活水平的提高,溽暑盛夏,人们很需要有一个舒适的温度和湿度的环境,空调设备的应用就日益增多,因而建筑的总能量消耗,及按人口或面积的能量消耗也随之逐年增长。初步调查空调制冷系统的能量消耗,在民用建筑中占总能量消耗的45%以上,有的达到65%,说明了空调制冷系统能量消耗是相当大的。如何做到既降低能耗,又为人民生活、工作创造一个舒适的环境,是需要认真关注的一项节能工作。空调技术中降温去湿是重要环节,制冷机是空调工程的核心没备,常用的设备有活塞式
With the development of economic construction and the improvement of people’s living standards, people are in great need of a comfortable environment of temperature and humidity. The application of air-conditioning equipment is increasing day by day. As a result, the total energy consumption of buildings and the population or area The energy consumption also increases year by year. A preliminary investigation of the energy consumption of air-conditioning and refrigeration systems accounted for more than 45% of total energy consumption in civil buildings, and some reached 65%, indicating that the energy consumption of air conditioning and refrigeration systems was considerable. How to reduce energy consumption and create a comfortable environment for the people’s life and work is an energy-saving task that requires careful attention. Cooling and dehumidification is an important step in air-conditioning technology. Refrigerators are the core of air-conditioning projects. Commonly used equipment is piston-type.
