摘要
提出以空气源热泵冷热水机组为冷热源设备,采用辐射地板和风机盘管分别为系统的供暖和供冷末端,并与以地暖循环水和辐射地板为低温热源的水源热泵热水器结合,构建家用空调、供暖与生活热水联供系统,阐述其工作原理,并建立其性能模型,分析系统中空气源热泵冷热水机组及水源热泵热水器的全年运行性能。结果表明:该系统中的冷热水机组的全年运行能耗与常规系统的冷热水机组相当;其水源热泵热水器相对于采用空气源热泵、燃气和电热水器制取生活热水而言,年节能率分别为18. 0%、55. 0%和80. 0%;虽然水源热泵热水器从房间辐射地板中取热,但可以规避地板结露风险。
A co-supply system for preparing domestic air-conditioning,heating and hot water is proposed up,in which air source heat pump water chiller-heater unit is applied for radiant floor heating and fan coils cooling and water source heat pump water heater that uses radiant floor and circulating water as low-temperature heat source are used for preparing hot water. The working principle of the system is pointed out and a performance model is established for the analysis of annual performance of air source heat pump water chiller-heater unit and water source heat pump water heater. The results indicate that energy consumption of air source heat pump water chiller-heater unit in the co-supply system is almost equal to normal system,the energy saving ratio of water source heat pump water heater is 18. 0%,55. 0% and 80. 0%respectively when compared with air source heat pump water heater,gas water heater and electricity water heater. What’s more,the risk of condensation on the floor can be avoided when the water source heat pump water heater absorbs heat from floor.
