活动冷库现场拼装工艺要求严格

活动冷库是一种工厂化生产、现场拼装的冷库,因为安装方便,组合灵活,所以其使用范围越来越广泛。但由于活动冷库方面的技术资料缺乏,加之少数活动冷库生产者为了降低生产成本,增加利润,导致目前市场上的部分活动冷库制冷工艺设计水平较低,库温达不到要求,冷库跑冷严重。因此造成的经济损失和水电浪费相当严重,这一点应该引起活动冷库生产经营者及用户的注意。

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.

制冷机组配置不合理机组的合理配制,直接影响到冷库的日常运行成本。机组与冷库的匹配有一较佳范围,但由于国产机组的型号及规格少,个别活动冷库生产者没有根据冷库设计计算负荷来配置,而是选用大制冷量机组或采用增配机组的台数来解决冷库快速降温的问题,这样就浪费了大量的电能并增加了机组的维护费用。

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.

机组的配置是根据冷库的计算负荷来确定的。但由于活动冷库进出货没有规律可循,机组的负荷难以确定,所以本文假定了一些使用条件:环境温度35℃,库内温度-5~-15℃,每天的最大进货量约为库容量的5%~8%,肉类贮存期限2~3个月,鱼类贮存期限1~2个月。根据冷库耗冷量及实际使用经验,活动冷库的机组可按表1配置。

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.

济南冷库安装各台机组不宜并联使用,除非设置曲轴箱油位平衡管。各机组之间应设置供液、回汽过桥阀,一般情况下分别运行或备用,需要时可调配使用。

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.
