Calculation of Chilled Water Requirements There are a number of units used to describechillercapacity. The most important ones are shown inTable 13.4. Table 13.4.Units Used to Describe Chiller Capacity UnitAbbreviationConversion Kilogram-caloriekcal1kcal=4.19 kJ (kilo-Joule) ...
A simple method and prediction model for calculating the cooling load of impinging jet ventilation system in office buildings 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 Ka...
The central plant's total cooling load under variable air volume systems was 1400 kW. Compared with the static load calculation method, the dynamic method reduced 33% of the chiller design capacity. When two chillers were used, different chiller combinations' annual cooling energy consumption ranged...
unit; PID calculation can be achieved according to the signal and the given values, enabling the control of 32 modulus start or shutdown at the most so as to realize the rational matching of output and load, save electric power and always maintain the optimal running stuatus of the unit....
For the absorption cooling system, because water and the LiBr solution are not ideal fluids, the following expression is used for the molar chemical exergy calculation [48]: (111)ex¯ch=(1/M¯sol)[∑i=1nyiex¯chk+R¯T0∑i=1nyiln(ai)] Applying this equation to the LiBr-water...
at electricity tariff rate of around RM 0.30 / kwhr = 135 x 0.4 x 30 x 12 SAVING PER YEAR =RM19,440.00 NOTE: the above may vary according to different country electricity tariff code Reduce energy consumption of at least 30% (Detail description and energy saving calculation with attached ...
The unit performs logical calculation based on the return water temperature of the chilled water to control the unit's operating status and start and stop. Each unit adopts four-level energy regulation to achieve efficient and energy-saving operation of the unit. Reasonable unit structure and g...
The cooling capacity of the absorption chiller was 6 kW. The results showed that the studied absorption chiller could deliver 65% of the total cooling load of the building with an average thermal COP of about 0.61. Marc et al. [12] presented the dynamic modeling of a LiBr–H2O single-...

If you are observing the remote temperature and flow meter sensors in your EMCS, that calculation will be based on the EMCS sensors and you are comparing that to the chiller. The chiller is reading a completely different pair of sensors than your EMCS mounted sensors. Upvote 0 Downvote Not...
