Activity is a kind of refrigerator factory production, on-site assembly cold storage, because of easy installation, flexible combination, so its use is more and more extensive. But due to the lack of data of activity cold storage technology combined with a few activities refrigerator producer in order to reduce the production cost, increase profits, causing part of the activities on the market at present the low level of cold storage refrigeration technology design, library can not meet the requirements, cold storage ran cold. So the economic loss and waste of water and electricity is quite serious, it should be a cause of refrigerator production operators and users' attention.
Jinan cold storage installation
Refrigeration unit configuration is not reasonable reasonable configuration of the unit, directly affect the daily operation cost of refrigerator. Units and matching a better range of cold, but due to low domestic models and specifications of the unit, individual event producers have no refrigerator according to the refrigerator design calculation load configuration, but choose large capacity units or do the Numbers of the unit is used to solve the problem of cold storage cooling rapidly, thus wasting a large amount of electric energy and increases the maintenance costs of the unit.
Configuration of the unit is based on computational load to determine the cold storage. But as a result of activities into the refrigerator no rules to follow, delivery of the unit load is difficult to determine, so this paper assume that some of the conditions of use: ambient temperature 35 ℃, the temperature inside - 5 ~ 15 ℃, the maximum daily were about database is 5% ~ 5%, 2 ~ 3 months storage of meat, fish storage period 1 ~ 2 months. According to the experience of the cold storage of cold consumption and practical use, activity of cold storage unit according to the configuration in table 1.
Jinan to install the refrigerator units should not be used in parallel, unless set crankcase oil level balance tube. Between each unit should be set for the liquid, steam back across the bridge valve, normally run or stand-by respectively, can be prepared using when necessary.
