Mar 12, 2013 This post is a continuation of Cooling Tower Best Practices: Water Conservation (Pt.1). Maximizing the energy efficiency of a cooling system requires evaluation of the entire cooling system (cooling tower, chiller, heat exchangers, etc.) and can often be significantly improved by maximizing the cleanliness of the heat transfer surfaces in the tower and cooling …

Mar 25, 2022 Chiller plants consume the most power of any component in a lot of buildings. Cooling demand accounts for typically 40-50% of those building’s total energy consumption. So it is important to pay attention to your chiller’s efficiency, as it can be both costly and wasteful. If you have an old or “standard” chiller – or if you have one that is not operating correctly – you …

Nov 03, 2020 One of the energy-efficient heat reclaim options for the hot water loop, or hot liquor tank (HLT), is a desuperheater heat reclaim. This energy-efficient feature of process chillers helps produce free hot water by ‘desuperheating’ the compressor’s discharged gases. An economizer can also optimize the hot water reclaim by cooling the ...

Sep 10, 2019 Chiller Efficiency Comparisons. By comparison, water-cooled chillers are more efficient than air-cooled variants. Air-cooled chiller efficiency is dependent on the temperature of the ambient air being used in its cooling system. The higher the temperature of the circulating cooling air, the less efficiently an air-cooled chiller will perform.

Substituting actual values, 480,000 Btu/hr/24.8 kW/hr = 480,000 Btu/hr/24,800 watts/hr = 19.35. This is very high cooling performance compared to the 2010 SEER standards of 13-14 for domestic air conditioning which reflects the higher efficiency of the chilled water strategy. COP would be the EER (19.35) X 0.293 = 5.67.

Therefore, hybrid chillers are slightly more efficient than air-cooled chillers but still, they are less efficient than water-cooled chillers. Most of the time, hybrid chillers have an efficiency of around 0.75 kW/ton. Due to the nature of evaporative cooling, the performance of hybrid chillers is dependent on the outdoor wet-bulb temperature.

This is true for Rchling Automotive. In cases like this, a water-cooled chiller is an excellent solution for the chilled water system. A water-cooled chiller is the most energy efficient chiller design available. It can utilize the cooling tower system for its condenser cooling, which eliminates the need for multiple fans for forced air cooling.
