摘要:
对空气源热泵双末端进行实际应用,测试风机盘管和地面辐射两种空调末端冬季供暖时的送风温度、地面温度、室内空气温度、主机供回水温度及不同地面装饰材料房间的供回水温度和地面温度,进而得出两种空调末端的提温速度及室内垂直温度分布. 研究结果表明:前者送风温度的升温速度是后者提温速度的11.2倍,且在两种空调末端供热下,前者室内1 m处空气温度的升温速度是地暖末端的3.73倍,因此前者使室内能更快达到室内舒适的温度; 地暖辐射虽然使室内升温速度慢,但房间的垂直温度分布的均匀性要优于风机盘管. 主机室外机化霜对风机盘管末端的送风温度影响较大,而辐射地面末端由于地面混凝土层等材料具有蓄热性,对辐射地板表面温度和房间温度影响较小. 地暖末端供暖时,大理石地面的升温速度是木地板的1.67倍,因此大理石地面能更快达到舒适温度的需求.
Abstract:
The paper conducts an air source heat pump double terminal practical application,tests the supply air temperature,ground temperature,indoor air temperature,main engine supply and return water temperature and supply and return of rooms with different floor decoration materials during winter heating at the fan coil and ground radiation air conditioner terminals water temperature and ground temperature,and then gets the temperature increase speed and indoor vertical temperature distribution of the two air conditioners. The results of the study show that:the former’s supply air temperature rises at a rate of 11.2 times that of the latter’s questioning rate,and under the two types of air-conditioning terminal heating,the former’s indoor air temperature at 1m rises at 3.73 times that of the floor heating terminal. It can reach a comfortable indoor temperature faster. Although the floor heating radiation slows the indoor heating speed,the uniformity of the vertical temperature distribution in the room is better than that of the fan coil.The defrosting of the main engine outdoor unit has a greater impact on the air supply temperature at the end of the fan coil. The end of the radiant floor,because the concrete layer of the ground has heat storage properties,has little effect on the surface temperature of the radiant floor and the temperature of the room. When the floor heating end is heated,the heating rate of the marble floor is 1.67 times that of the wooden floor,so the marble floor can reach a comfortable temperature faster.
