我国地下冷库自60年代后期开始试建,70年代发展迅速,到80年代初估计建成总贮藏能力达13万吨。(一般每座能力均不大于千吨,并附有肉冻结间,很大部份是在四川省。)限于客观条件,当时只是简单地打几个洞,装上制冷设备和冷藏门,就降温投入使用。82年四川省制冷学会与四川省食品公司召开的《山洞冷库座谈会》上,30余座冷库普遍反映:与地面冷库相比较,地下冷库单位吨耗冷量大,冷库漏水严重,冷库壁温高,影响储藏食品的质量。个别冷库岩层裂隙因受温度变化影响,缝隙扩大,裂隙水结冰,冻胀。大部份地下冷库停产待修,甚至报废,给人民财产造成损失,而且几乎断绝地下冷库的发展前途。有关同志认为所以出现前述一系问题,关键在于缺乏一套需在岩层中有裂 The construction of underground cold storage in our country began in the late 1960s and was rapidly developed in the 1970s. By the early 1980s, it is estimated that the total storage capacity will reach 130,000 tons. (Usually each capacity is not more than one thousand tons, with meat frozen, mostly in Sichuan Province.) Limited to the objective conditions, was only a few holes at that time, fitted with refrigeration equipment and freezer doors Put into use cooling. In 2008, more than 30 cold storage warehouses were universally reflected in the “Cave Cold Storage Symposium” held by Sichuan Institute of Refrigeration and Sichuan Food Co., Ltd. In comparison with the surface cold storage, the unit consumption of underground cold storage units was large, the water leakage in cold storage was serious, High, affecting the quality of stored food. Due to the influence of temperature change, the cracks in individual cold storage rock stratum expand, the fissure water ice and frost heave. Most of the underground cold storage was discontinued for repair or even scrapped, causing losses to people’s property and almost severing the development prospect of the underground cold storage. The relevant comrades think that the emergence of a series of problems mentioned above lies in the lack of a need to have a crack in the rock formation
