摘要
从湖体水温、热泵机组能效、冷排水对水环境的影响及热泵系统节能性四个方面分析了湖水源热泵在冬季供暖的适应性。研究表明，湖水源热泵供暖技术具有良好的节能效益，实测热泵机组能效达到4.34～4.81，相对传统的风冷热泵、电锅炉、燃气锅炉系统而言，水源热泵系统的节能率分别达到5%、68%和29.8%。
The adaptability of lake water source heat pump in winter for heating is analyzed from aspects of lake water temperature, energy efficiency of heat pump units, environmental impact of cooling water drainage and energy saving of heat pump systems. The research shows that lake water source heat pump has good energy-saving effect when used for heating, with measured energy efficiency of heat pump units reaching 4.34 ~ 4.81. The relative energy-saving rate of water source heat pump system reaches 5%, 68% and 29.8% compared with air source heat pump, electric boiler and gas boiler respectively.
