Calculation of Chilled Water Requirements There are a number of units used to describe chiller capacity. The most important ones are shown in Table 13.4. Table 13.4. Units Used to Describe Chiller Capacity UnitAbbreviationConversion Kilogram-calorie kcal 1 kcal = 4.19 kJ (kilo-Joule) British therm...
The other is the indirect measurement, which calculates building cooling load based on chiller models using the instantaneous chiller electrical power input, etc. The combination strategy is tested using the field data collected from the central plant of the air-conditioning system in a high-rise ...
the minimum entering cooling water temperature is obtained by dynamic load calculation, and finally, calculates the all-year energy consumption and energy consumption under different building load demand based on different chiller unit configurations, accordingly obtaining the optimal chiller unit ...
A simple method for calculating the cooling load is proposed for IJV system.The simple calculation method is applied using the cooling load ratio (α).Thre... J Hu,Y Kang,Y Lu,... - 《Building & Environment》 被引量: 0发表: 2024年 Quantifying Uncertainty with Conformal Prediction for Hea...
Energy saving is one of the most important issues in high-tech manufacturing industries, such as semiconductor and electronics, because large chilled water systems are used to satisfy big cooling load requirements. In this paper, a new optimal integrity scheme based on a two-stage strategy, includ...
Total cooling load based chiller sequence in multiple-chiller plants is essentially the best approach to stage a chiller on or off in order to satisfy thermal comfort requirement and achieve energy efficiency simultaneously. In practice, however, this approach cannot be reliably implemented. The reason...
