Performance of ice storage system utilizing a combined partial and full storage strategy


Abstract
A combined system is a new thermal storage strategy adopted in this study with which the two other known strategies namely, partial and full load, are compared. The results revealed that the combined system requires larger equipment size than that required by partial system to satisfy the same cooling load. Factors F and F that p f may be multiplied by the daily average cooling load to determine the optimum chillers size for a combined system are found. These factors are applicable for any cooling load and are based on a given chiller condensing and evaporating condition as used in this study. These factors are found to vary with the number of on-peak hours. Combined strategy required chiller size was found to decrease with decrease in on-peak period, hence the optimum chiller size for this new strategy was found to occur at zero on-peak hours, and i.e., when the combined system starts to operate as a partial strategy system.

摘要
對(duì)于兩個(gè)已知的部分和整體儲(chǔ)能戰(zhàn)略來說，復(fù)合系統(tǒng)是一種新型的蓄熱方式。結(jié)果表明。在滿足相同的冷負(fù)荷時(shí)，復(fù)合系統(tǒng)比局部系統(tǒng)需要更大尺寸制冷機(jī)。我們采用Fp和Ff這兩個(gè)系數(shù)乘以日平均冷負(fù)荷，來確定冷水機(jī)組最佳尺寸。這些因素適用于任何冷負(fù)荷，并且正在研究在給定冷水機(jī)組冷凝和蒸發(fā)條件下的使用情況。在峰值變化的數(shù)據(jù)中發(fā)現(xiàn)這些因素。發(fā)現(xiàn)聯(lián)合儲(chǔ)能策略要求冷水機(jī)組的型號(hào)隨著電高峰期的降低而減小。因此，當(dāng)聯(lián)合系統(tǒng)作為部分儲(chǔ)能策略開始運(yùn)行，對(duì)于這項(xiàng)新戰(zhàn)略聯(lián)合冷水機(jī)組在用電高峰期的型號(hào)被發(fā)現(xiàn)。
