تحسين أداء أنظمة التكييف المركزي باستخدام معيار جديد

الملخص EN

An important factor by estimating of the necessary capacities for the different components of the central air-conditioning plants is the design outside temperature.

Because of its extremity, this temperature enlarge the capacities, although it keeps on only for a short time during the operation period, and so an important ratios of the capacities have to produce only a few percent of the annual necessary energy.

The paper aims to reduce the capacities and operating costs of such like plants, by investigating a considerable ratio of the system capacity, which cover only about 5% of the seasonal necessary energy for heating and cooling, and to investigate proper solutions to cover the shortage of the necessary energy for a short time.

The proposed solution make it passible to reduce the general costs about 75% for cooling system and 50% for heating system.
