2022-4-7 · Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller''s compressor. This equivalent ton is …

2016-6-14 · If it matters, the chiller is running at a very low load right now with a 46.5F CHWS, 48.6F entering chiller water, 83.6F entering CW, 87.4F leaving CW. Your electrical load calculation seems valid. The discrepancy in electrical power in vs cooling out is the coefficient of performance (although it seems a little high).

2022-4-2 · Less than three decades ago, full load kW/ton was still a widely used metric of chiller efficiency. It was only in the late 1980s that stakeholders in the industry realized that this indiion was incomplete because full load conditions are rare in real life situations.That was the beginning of better and fairer comparison metric.

2018-11-7 · How to Calculate Chiller Tonnage – Formula. The final step to convert your answer into tons of chiller capacity is to divide your result, Q (BTUs per hour), by 12,000 (the nuer of BTUs in one ton of cooling capacity). This will give you, in tons per hour, the chiller capacity that is needed to handle the process heat load.

The chiller is the main energy-consuming equipment of the central air conditioning system, and its performance largely determines the energy efficiency of the air conditioning system [].At the same time, a proper control and maintenance of the chiller is of crucial importance [12, 13].Therefore, choosing efficient chillers is an effective way to reduce the energy efficiency of the metro air
