Cooling storage type refrigeration and insulation tank

Abstract

The invention discloses a cooling storage type refrigeration and insulation tank, which comprises an insulation tank body, a refrigerating unit, cooling storage tanks, an electric power storage system and a temperature monitoring feedback system. The insulation tank body comprises a shell, an inner storage cavity and an insulation layer; the refrigerating unit comprises a high-efficient compressor, a condenser, an expansion valve and an evaporation coil; and the temperature monitoring feedback system comprises a temperature sensor and an intelligent change-over switch. The invention further discloses a working process of the cooling storage type refrigeration and insulation tank. The device is externally connected with a refrigeration power supply and a storage battery refrigeration power supply, so that the aims of high-efficient refrigeration and cooling storage of distributing nodes and regulation and cold release during a distribution process are achieved; during the distribution process of the device, storage battery power supply refrigeration and insulation as well as cooling storage and insulation are combined, so that a high-efficient and stable low-temperature cooling storage and insulation function of the device is ensured; and the cooling storage tanks in the device can be flexibly arranged according to the range factors such as the quantity, the distributing distance, and multiple distributing terminals of the distribute goods, so that the individuation and the sensitivity in applying the insulation tank are improved, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a cold storage type refrigeration insulation box. Background technique [0002] Food cold chain is an important guarantee for food quality and safety. As the proportion of frozen and refrigerated food in the lives of urban residents in my country is gradually increasing, the cold chain logistics industry is developing rapidly. At present, the technology development and facilities of my country's core cold chain logistics links are gradually improving, which can basically meet the medium and long-distance transportation of large-capacity frozen foods from production bases to urban cold storage and large cold chain markets. However, from the distribution center to many scattered final retail terminals, the current technological development is relatively weak, that is, the "last mile" cold chain distribution problem. For cold chain distribution that requires strict and seamles...

Problems solved by technology

However, in principle, phase change cold storage mainly relies on solid-liquid phase change latent heat storage, there is a lower limit of phase change temperature, and the cold storage efficiency is not high

The principle of semiconductor refrigeration is generally based on the Peltier principle. The hot end of the semiconductor refrigeration sheet of the incubator is conventionally cooled by air, and the heat dissipation effect of the hot end is poor, resulting in low cooling efficiency and short holding time.

To sum up, there is no cold storage refrigeration incubator with low temperature limit, high cold storage efficiency and long heat preservation time.
