一、引言冷藏库是个投资大,能源消耗比较大的生产经营企业。如何提高经济效益,降低生产成本是目前企业整顿中的首要问题,而降低能源消耗又是成本降低中举足轻重的问题,冷库的能源消耗主要表现在耗电上。象滨州冷藏厂不过是日冻结量30t,年冻结量不到3000t,冷藏量1000t的小库,全年耗电量均在60万KWh以上,而冷库占90％,冻结吨成本较高(83年为206kwh/t)。可见,冷库节能首先在节电方面潜力是很大的。本文专来讨论电机匹配这个带有普遍性的突出问题,以期在理论上增加对改革电机匹
I. Introduction Refrigerator is a large investment, energy consumption is relatively large production and management enterprises. How to improve the economic efficiency and reduce the production cost is the most important issue in the rectification of the enterprises at present, and reducing the energy consumption is the decisive issue in the cost reduction. The energy consumption of the cold storage mainly manifests in the power consumption. Binzhou refrigerators, for example, are but small reservoirs with a daily freeze of 30 tons, annual frozen volume of less than 3000 tons and cold storage of 1,000 tons. The annual electricity consumption is above 600,000 KWh, while cold storage accounts for 90% of the total. Year is 206kwh / t). Can be seen, cold storage energy saving potential first of all is great. This article is dedicated to discuss the motor matching with this prominent problem in general, with a view to increasing the theoretical motor
