With the demand for storage and pre-cooling of fruits, vegetables, grain, flowers and other agricultural and sideline products, medicinal materials, food, and fine chemical raw materials, how to save energy and efficiently meet these demands has become an important direction for the development of the current cold chain. The miniature energy-saving cold storage is a storage facility with simple operation, reliable performance and good effect developed for the main management mode of agricultural production in my country and the economic and technical level of rural households. It plays an active role in promoting the development of the cold chain of agricultural products. effect.

According to the reporter's understanding, because the micro energy-saving refrigerator can be widely used in the storage and pre-cooling of agricultural and sideline products such as fruits, vegetables, grains, flowers and other agricultural and sideline products, as well as medicinal materials, food, and fine chemical raw materials, it is suitable for urban and rural households and collectives in northern and southern my country. In the off-peak season, the advantage of local resources is changed into an important carrier of the economy. The refrigerant filling and debugging installed in the micro energy-saving cold storage have been strictly tested before leaving the factory. At the same time, the installation is convenient and quick. It only needs to connect the indoor unit and the outdoor unit with pipes and connect the power to work. Secondly, the refrigeration unit installed in the micro energy-saving cold storage adopts imported fully enclosed refrigeration compressors, and the main control components can also be made of foreign products, so the operation is safe and reliable, and the trouble-free operation time is long. In addition, the self-control system designed for the miniature energy-saving cold storage adopts microcomputer control, which is accurate in temperature control and simple in operation. Temperature inside the library. In addition, the unit of the micro energy-saving Beijing cold storage adopts hot air or electric heating defrosting method, the defrosting time is short, and the temperature fluctuation in the warehouse is small during the defrosting period. The warehouse built according to the design points of the miniature energy-saving cold storage has fast cooling speed, good thermal insulation performance, and small temperature fluctuation of the air-conditioned warehouse. Generally, within 48 hours after the empty warehouse is turned on, the temperature of the combined cold storage can be reduced from 20 °C to 0 °C; the fruit is pre-cooled in the early stage. In the cooling stage, the daily power consumption of the equipment is generally 40-50 degrees. After the temperature of the medical cold storage is stable, the daily power consumption is only 7-8 degrees. In the northern region, natural cold source ventilation can be used to cool down in winter, and the monthly power consumption is very low. . For promoting the development of cold chain, micro energy-saving cold storage has great potential.
