双工况空气源热泵变工况调节特性试验研究
Experimental research of the regulation characteristics in air-source heat pump with duplex mode under variable conditions
摘要
Abstract
In order to effectively deal with the current energy shortage situation, which is increasingly getting worse as energy consumption of buildings continues to rise, while at the same time ensure improved levels of comfort, an air source heat pump chiller with duplex mode DC speed controller was designed based on the high efficiency and speed changing characteristics of the DC compressor. One unit has two water outlets connecting the floor radiated air-conditioning system and domestic hot water system, respectively. The variable condition experiment shows that the units control outlet water temperature by regulating compressor frequency, avoiding large energy consumption and impact to the power grid due to repeated starting and stopping of the units. In addition, the duplex mode DC controlled heat pump chiller may control the outlet water temperature steadily, rapidly and accurately by changing the operating mode, thus controlling the difference between the actual outlet water temperature and the set value within 0.5 ℃ basically.关键词
