Abstract Stratum ventilation (SV), a new indoor air distribution strategy, has been promoted for applications in different building premises in recent years. Compared to the conventional mixing ventilation (MV), the prominent advantage of SV is that indoor thermal comfort can be satisfied with a relatively high supply air temperature, hence less energy consumption in refrigeration. In solar air-conditioning, the energy performance can also be facilitated by high-temperature cooling. As such, the potential of SV to be involved in solar air-conditioning was evaluated. In this study, the solar air-conditioning systems included solar absorption cooling system (SAbCS), solar adsorption cooling system (SAdCS), solar desiccant cooling system (SDCS), hybrid solar absorption-desiccant cooling system (HSAbDCS) and hybrid solar adsorption-desiccant cooling system (HSAdDCS). Their performances using SV and MV were determined through year-round dynamic simulation. Compared to the counterpart using MV, SAbCS, SAdCS, SDCS, HSAbDCS and HSAdDCS associated with SV could have 35%, 54%, 59%, 29% and 44% saving in the annual primary energy consumption for building in subtropical climate respectively. Benchmarked with the conventional air-conditioning system, they could have primary energy saving up to 30%. Consequently, solar air-conditioning and SV can have synergetic merit in building application in hot and humid city.

室内空气分配策略对太阳能空调系统的影响研究

摘要 分层通风（SV）是一种新的室内空气分配策略，近年来已被推广应用于不同的建筑场所。与传统的混合通风（MV）相比，SV的突出优点是可以在较高的送风温度下满足室内热舒适性，从而减少制冷能耗。在太阳能空调中，高温冷却也可以促进能源性能。因此，评估了 SV 参与太阳能空调的潜力。在本研究中，太阳能空调系统包括太阳能吸收冷却系统（SAbCS）、太阳能吸附冷却系统（SAdCS）、太阳能干燥剂冷却系统（SDCS）、混合太阳能吸收-干燥剂冷却系统 (HSAbDCS) 和混合太阳能吸附-干燥剂冷却系统 (HSAdDCS)。他们使用 SV 和 MV 的表现是通过全年动态模拟确定的。与使用 MV 的对应物相比，SAbCS、SAdCS、SDCS、HSAbDCS 和 HSAdDCS 与 SV 相关可分别节省 35%、54%、59%、29% 和 44% 的亚热带气候建筑年度一次能源消耗。以传统空调系统为基准，它们可节省高达 30% 的一次能源。因此，太阳能空调和SV在湿热城市的建筑应用中具有协同优势。与SV相关的HSAbDCS和HSAdDCS可分别节省35%、54%、59%、29%和44%的亚热带气候建筑年一次能源消耗。以传统空调系统为基准，它们可节省高达 30% 的一次能源。因此，太阳能空调和SV在湿热城市的建筑应用中具有协同优势。与SV相关的HSAbDCS和HSAdDCS可分别节省35%、54%、59%、29%和44%的亚热带气候建筑年一次能源消耗。以传统空调系统为基准，它们的一次能源节省高达 30%。因此，太阳能空调和SV在湿热城市的建筑应用中具有协同优势。
