提出了一种新型的地源热泵-辐射供冷/暖复合空调系统,分析了该系统的原理和特点.该系统被应用于镇江西津渡展览馆中,并利用TRNSYS软件对其热舒适度和能耗进行了模拟分析.结果表明,地源热泵-辐射供冷暖复合空调系统在冬季采暖运行时,地板辐射和顶板辐射方式均具有良好的热舒适度,且无须采用机械通风;在夏季空调运行时,地板辐射和顶板辐射必须配合合理的机械通风,才能具有良好的热舒适度;在同样的热舒适度条件下,顶板辐射供冷/暖的全年能耗比地板辐射低.
A new type of ground source heat pump - radiant cooling / heating compound air conditioning system is proposed and the principle and characteristics of the system are analyzed.The system is applied to Zhenjiang Xijin Ferrying Exhibition Hall, and the thermal comfort and Energy consumption were simulated.The results show that the floor radiant and roof radiating methods have good thermal comfort without using mechanical ventilation when the ground source heat pump-radiant heating and cooling composite air conditioning system is heating in winter, Floor radiation and roof radiation must be combined with reasonable mechanical ventilation in order to have good thermal comfort; under the same thermal comfort conditions, the annual energy consumption of roof cooling / heating is lower than that of floor radiation.
