本文提出了一种新型转轮除湿与双级热泵耦合的空调系统,首先采用热湿负荷独立处理的思想,利用双级热泵来满足室内冷负荷和转轮再生负荷的要求,而后建立了系统的物理模型并对该系统的性能参数进行了计算和分析,在满足室内热湿负荷和转轮再生负荷的要求下,双级热泵的2台机组均可同时工作在较高效率范围内。从节能、环保和室内空气品质的角度分析,该系统具有很大的发展潜能。
In this paper, a new type of air conditioning system with dual-stage heat pump and dehumidification is proposed. Firstly, the concept of independent processing of heat and moisture load is adopted. The dual-stage heat pump is used to meet the requirements of indoor cooling load and runner regeneration load. Physical model and performance parameters of the system were calculated and analyzed to meet the requirements of indoor heat and moisture load and runner regeneration load, two units of two-stage heat pump can work at the same time in a higher efficiency range. From energy saving, environmental protection and indoor air quality point of view, the system has great potential for development.
