为了满足快速发展的公共建筑等大型低温热水用户的用热需求,迫切需要研究和发展适用的卫生热水制备技术,用于取代传统的化石燃料锅炉和电锅炉,并改善高位能的使用。作为一种高位能使用的典范,空气源热泵热水机组由于其节能和环保特性,产业化势在必行。本文在分析传统空气源热泵热水器研究概况的基础上,针对其不足,提出了一种大型蓄能式空气源热泵热水机组新流程。该流程不仅具有常规空气源热泵热水机组的优点,而且还能起到电力的削峰填谷作用,利用夜间低谷电,进一步降低运行费用,同时拥有更合理的除霜方式、提供免费供冷等突出的优越性。这势必带动热泵热水机组的产业化发展。
In order to meet the heat demand of users of large-scale low-temperature hot water such as public buildings and the rapid development, there is an urgent need to research and develop suitable sanitary hot water preparation technology to replace the traditional fossil fuel boilers and electric boilers and to improve the use of high energy. As a high-level model that can be used, air-source heat pump hot water unit is imperative due to its energy saving and environmental protection features. Based on the analysis of the research status of traditional air source heat pump water heaters, this paper presents a new process of large-scale energy storage air-source heat pump hot water units. The process not only has the advantages of conventional air-source heat pump hot water unit, but also can play a peak load of electric power valley filling, the use of night trough electricity to further reduce operating costs, while having a more reasonable way to defrost, to provide free cooling Prominent superiority. This is bound to lead the industrialization of heat pump hot water unit development.
