摘要
提出了一种新型的无水地暖热水两联供空气源热泵系统，其特征是制冷剂直接在地暖埋管中冷凝，同时高温的制冷剂在外绕盘管式热水器中进行热交换制取生活热水，实现室内供暖和生活热水供应。加工出样机并在单独地板采暖、两联供及单独热水器三种模式下进行测试。实验结果表明：无论单独地板采暖模式、两联供模式还是单独热水器模式，房间地板表面温度维持在25 ℃~33 ℃，空气温度维持在18~22 ℃。毛细管地板蓄热作用，停止向房间供热近113~245 min之内房间空气温度依然在18 ℃以上；在优先满足室内采暖要求下，该系统在环境温度为-5 ℃时，经过572.3min热水器水温升至45 ℃；系统制热量和
EER
最低分别达到2.70 kW和3.55。
Abstract
A new type of air source heat pump system combined waterless floor heating and hot water supply was proposed
which is characterized in that the refrigerant is condensed directly in the buried pipe for floor heating
at the same time
the high temperature refrigerant is exchanged in the outer coil water heater to produce domestic hot water. The prototype was processed and tested in three modes: single floor heating
two combined supply and single water heater. The experimental results show that the surface temperature of the floor is maintained between 25 ℃ and 33 ℃
and the air temperature is maintained between 18 ℃ and 22 ℃ whether in the sole floor heating mode
dual supply mode
or single water heater mode. Due to the heat storage effect of the capillary floor
the air temperature in the room remained above 18 ℃ within 113~245 min of stopping heating to the room. When the ambient temperature is -5 ℃
after 572.3 min
the water temperature of the water heater rose to 45 ℃; The minimum system heating capacity and
EER
can reach to 2.70 kW and 3.55
respectively.
