【摘要】 本文回顾自建国以来我国电力工业和热泵工业的发展历程。我国发电装机容量从1949年的185万千瓦增长到2014年的13.7亿千瓦,发电效率和输电技术达到国际先进水平,我国已经基本实现了电气化。中国真正的热泵工业始于上世纪八十年代,从简单的房间空调器,发展到现在品种齐全的热泵产品,包括热泵式房间空调器、热泵式多联机、单元式空调机、热泵热水机、水源热泵等。热泵的平均制热系数从上世纪八九十年代年的2.5,达到当前3.5以上。通过计算可知,我国热泵供热的一次能源利用率是燃煤锅炉的2倍,热泵技术具有节能、省钱和环保的三重效果.更多还原

【Abstract】 The development of electric power industry and heat pump industry in China are revi ewed in this paper. In our country the installed capacity is increased from 1850 MW in 1949 to 1370000 MW in 2014, the generation and transmission efficiency are increa sed to the advanced level in the world, which means the country is electrified mainly. The heat pump industry is developed since the 1980’s from simple room air conditio ner to the heat pump range production, including heat pump room air conditioner, mul ti-connected air condition(heat pump)unit, unitary air conditioner, heat pump water he ater, water source heat pump and so on. The average COP of heat pump products inc reased since 2.5 in 1980-1990 to above 3.5 nowadays. According the calculation, the primary energy utilization rate is two times of coal boiler. The heat pump technology has the three advantages in save energy, save money and environment protection.更多还原
