Due to the different approaches in determining the ventilation airflow rate per person for workspaces, where high-temperature air conditioning systems are used for air conditioning, problems with the condensation of water vapour on the cold surfaces of the system can occur. The article analyses the risk of condensation in various European cities using the available climatic data. Systems with cooling ceilings and cooling beams with a ventilation device operating in parallel are taken into account. Different ventilation airflow rates per person were analysed. On the example of a room equipped with high-temperature cooling, an energy simulation calculation is performed, which includes a ventilation and air-conditioning system with the possibility of capacity control. It is clear from the results that the condensation of water vapour can be prevented by technical measures at the cost of reducing the cooling capacity, which can affect the achievement of the thermal comfort of those present. In the end, suitable solutions are discussed, which should already be adopted at the time the device is designed so that the risk of condensation is not a major obstacle in the operation of these energy-efficient systems. An irreplaceable role in the operation of high-temperature cooling systems is played by a measurement and control system with a suitable algorithm to prevent condensation.

由于在使用高温空调系统进行空调的工作空间中确定人均通风量的方法不同，因此会出现水蒸气在系统冷表面凝结的问题。本文使用可获得的气候数据分析了欧洲各个城市的凝结风险。考虑了带有冷却顶板和带有并行运行的通风装置的冷却梁的系统。分析了每人的不同通风量。以配备有高温制冷系统的房间为例，进行了能量模拟计算，其中包括通风和空调系统，并可能进行容量控制。从结果清楚地看出，可以通过技术措施来防止水蒸气的冷凝，但是以降低冷却能力为代价，这会影响所存在的人们的热舒适性。最后，讨论了合适的解决方案，在设计设备时应已采用这些解决方案，以使冷凝风险不是这些节能系统运行的主要障碍。具有合适算法以防止冷凝的测量和控制系统在高温冷却系统的运行中扮演着不可替代的角色。在设计设备时应该已经采用了这种方式，这样冷凝的风险就不会成为这些节能系统运行的主要障碍。具有合适算法以防止冷凝的测量和控制系统在高温冷却系统的运行中扮演着不可替代的角色。在设计设备时应该已经采用了这种方式，这样冷凝的风险就不会成为这些节能系统运行的主要障碍。具有合适算法以防止冷凝的测量和控制系统在高温冷却系统的运行中扮演着不可替代的角色。
