摘要

我国北方较多公共建筑分别采用直膨式空调供冷和市政热水供暖，需要2套室内末端。提出了一种利用市政热水直接供暖的水氟互联空调系统，其室内机为三介质换热器，可以利用市政热水或直膨的方式加热室内空气，实现直膨式空调和集中热网供暖的灵活切换；以北京某办公建筑为例，按夏季空调工况进行机组选型，建立了系统的性能模拟模型，并分析其在供暖季及过渡季的供暖效果。结果表明：该系统在供暖季采用市政热水供暖时所需的用户侧水温低于54 ℃；在过渡季采用直膨式供暖时其机组容量高于过渡季尖峰负荷，且在49%的运行时间内能效超过3.5。提出的水氟互联空调系统采用一套末端保障夏季空调和冬季供暖需求，并在市政热水停暖后可用直膨方式供暖，简化了现有系统形式，提高了供暖舒适性。

Abstract

In northern China

public buildings commonly use direct-expansion air-conditioning systems for cooling and district heating networks for heating

necessitating separate terminals for each function. This study proposes a multi-connected air conditioning system capable of utilizing refrigerants and water for direct heating with hot water from district heating systems. The system integrates three-fluid heat exchangers within indoor units

enabling seamless switching between direct-expansion air-conditioning and district heating systems. Using an office building in Beijing as a case study

the system was evaluated under summer cooling design conditions

and its heating performance during winter and transitional seasons was analyzed. Results reveal that during winter

the system requires user-side water temperatures below 54 ℃

while in transitional seasons

the direct-expansion mode delivers unit capacities exceeding peak heating demands with energy efficiency surpassing 3.5 over 49% of operating hours. This system simplifies existing configurations by providing a single terminal for year-round heating and cooling

enhancing efficiency and thermal comfort.
