Thermal insulation and energy saving: The mobile cold storage has a good sealed thermal insulation effect, and the operation is energy-saving and environmentally friendly. with the traditional dry-type evaporative refrigeration system, the efficiency is increased by more than 20%, which can save energy and cost for users. The of the combined cold storage has good thermal insulation performance, fast cooling speed, and long insulation time. Compared with other cold storage materials, it can save 30 - 4% energy. High-efficiency freezing: The full-liquid evaporation is used, which has high efficiency and short freezing time, and can ensure the freshness of frozen products. products can be frozen in a short time after fishing or slaughtering. Intelligent monitoring: It provides an Internet of Things remote monitoring platform, which can monitor and maintain the equipment through the network, which is convenient to grasp the operation of the cold storage in time and make corresponding adjustments.
