1, gas conditioning cold storage is a more closed cold storage, when the temperature inside the library rise and fall, the gas pressure also changes, the library inside and outside will form a certain air pressure difference. So air pressure balance safety device is necessary to set. Otherwise, it is easy to make the library body pressure seepage gas and destroy the “gas conditioning” state.
2, gas-conditioned cold storage can also be a variety of forms, there are civil engineering forms, but also the library board assembled type. However, due to the above characteristics of gas-conditioning cold storage, storage time and longer, in the gas-conditioning cold storage body design should pay attention to the selection of appropriate forms and materials.
3, air conditioning cold storage design is recommended to use two-speed chiller. If the use of direct evaporative chiller should pay attention to minimize the difference between the evaporation temperature and the temperature of the library (usually choose 3 ° C below, to reduce the evaporator frost, dehydration, maintaining a high relative humidity in the library), so, relative to the general cold storage evaporator gas conditioning cold storage in the chiller heat transfer area should be appropriately increased. If the fruits and vegetables picked to the warehouse before the timely pre-cooling, freshness is better.
4, gas conditioning cold storage door selection is also key, if the gas conditioning cold storage door gas tightness is not good, easy to “seepage of gas” resulting in the required “gas conditioning” state damage.
5, gas conditioning cold storage of goods for fruit and vegetables, in order to reduce dry consumption, heat transfer temperature difference is small to maintain the high relative humidity required in the library is an effective method.
