空气源户式机组地板采暖系统应用研究

为了研究空气源热泵冷热水机组作为地板采暖的热源的运行特性，以一围护结构保温良好的房间为研究对象，分别测试了热泵机组采用低水温进行供暖运行时的能效、在高低温的运行环境下供暖房间内温度的变化。结果表明，在保温性能良好的建筑，采用热泵机组以35℃的低供水温配合高效地暖盘管进行地板供暖，既能保证室内的舒适性，又具有良好的节能效果。得出用于地板采暖的空气源热泵机组，其控制开停机的温差需要比传统的空气源热泵机组大，在低温环境下，机组性能衰减的特性对室内达到相同供暖效果所需的时间影响不大，为设备、工程设计提供参考。

Application Study on Floor Heating System with Air Source Residential Air-conditioning

To study operating characteristics of the floor heating system with air source residential air -condition-ing, experimental research on behavior of the system applied in Heat insulations good room , Testing the energy effi-ciency when the heat pump unit uses a low water temperature for the heating operation and temperature changes of indoor when the heat pump unit operation in the environment of the high and low temperature .The results show that floor heating with low water temperature of 35 degrees supplied by heat pump units in buildings with good insulation properties , it is not only ensure the comfort of the room , but also has a good energy saving effect.It is also show that the range of temperature used control switch is different between in Traditional air source heat pump units and the floor heating system with air source residential air -conditioning , and the attenuation characteristics of the unit performance in low temperature environment has little effect on the time reguired for achieve the same heating effect of indoor , which providing a reference for equipment and engineering design.
