Apr 26, 2017

1 domestic refrigerator development situation in 1955, China began to build the first cold storage, the total capacity of 40 thousand tons, the beginning of 1968, Beijing to build the first mechanical fruit cold storage, in 1978 to build the first air conditioned, as of the end of 1991, China has built 4 million 135 thousand tons of cold storage. In 1995, the advanced technology of combined gas reservoir was introduced for the first time by Kaifeng Air Separation Group Co., ltd.,

1 domestic refrigerator development situation in 1955, China began to build the first cold storage, the total capacity of 40 thousand tons, the beginning of 1968, Beijing to build the first mechanical fruit cold storage, in 1978 to build the first air conditioned, as of the end of 1991, China has built 4 million 135 thousand tons of cold storage. In 1995 by the open air Group Co. Ltd. first introduced combined gas transfer advanced technology, and the construction of 15 000t gas adjustment cold storage in Shandong Longkou success, creating a successful precedent in the large assembly type gas adjustment cold storage. In 1997 in Shaanxi, Xi'an built a 10000 tons of air conditioning cold storage, air tightness performance reached the international advanced level. In recent years, the construction of cold storage in our country is developing rapidly, which is mainly distributed in the main vegetable producing areas of the fruits and vegetables, as well as the vegetable bases in the suburbs of large and medium-sized cities. According to statistics, the existing refrigerated capacity has reached about 5000000 tons, including foreign investment, joint ventures and private storage accounted for about 500 thousand tons, owned about 4500000 tons of cold storage, belonging to domestic trade, agriculture, trade and industry system, including domestic system of cold storage capacity of about 3000000 tons, accounting for more than 60% of the total amount of the whole country. China's commercial system has a fruit and vegetable storage area of about 2000000 square meters, storage capacity of up to about 1300000 tons, of which a mechanical freezer of about 700000 tons, an ordinary Library of about 600000 tons.

2 the problem of domestic cold storage in our country as a major agricultural production, the development of cold storage is still lagging behind. Mainly in the following aspects:

(1) the utilization rate of equipment is low, which is manifested in the low utilization rate of space, and the low utilization rate of the two anniversary;

(2) part of the cold storage design is not standardized, there are many security risks;

(3) the equipment technology is backward, the management is extensive, the refrigeration way is backward;

(4) cold storage energy saving measures have not caused enough attention;

(5) the energy consumption of cooling equipment is large, and the degree of automation is low;

(6) in our country, the defrosting period and defrosting time are very long;
