Description

用于冷库的控制方法、装置及冷库、存储介质
本申请基于申请号为202310274744.1、申请日为2023年3月20日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及制冷技术领域，例如涉及一种用于冷库的控制方法、装置及冷库、存储介质。
背景技术
目前，冷库用于一些冷藏货物的存储。市面常见冷库形式一般有两种，一种用于中长期储存，另一种用于中转暂时存储。前者通常采用风冷式翅片蒸发器作为制冷系统的组成部分，并安装于冷库内部，其制冷装置采用常通电模式。当制冷系统工作时，利用风机将库内空气流经蒸发器进行热交换，以达到降低库内温度的目的。而后者内置蓄冷水箱，作为制冷系统组成部分的蒸发器装配于蓄冷水箱内部，其首先对蓄冷液体进行冷却以存储冷量，再利用自然对流方式冷却库内空气，从而达到降低库内温度的目的。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
第一种冷库在断电后温度回升较快，因此当其处于电力不稳定地区或存放较贵重货物时难以投入应用，除非配置额外的发电系统，否则存在货物损坏的风险。第二种冷库降温速度较慢，尤其在夏天同时存入大量负载的情况下，可能难以在有限时间内将库内温度降至最佳储存温度。因此，目前亟需一种能够兼顾快速降温和蓄冷保温的冷库方案。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。
