How to Manually Calculate Chiller Capacity for Your Process

How to Manually Calculate Chiller Capacity for Your Process

Apr 04, 2019 Convert result into tons of chiller capacity. Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example:20 tons/hr. Correct chiller tonnage for leaving water temp (LWT), if LWT is other than 50F:

What is Chiller Approach? - aircondlounge

Chilled water return is the water leaving the AHUs/FCUs and entering the chiller. The normal chiller evaporator approach is below 1C (1.8F) for new chillers. Hence, if the chilled water supply temperature is 6.7C (44F), the evaporating refrigerant temperature is around 6C (42.8F). Usually, chillers have built-in refrigerant ...

Jan 05, 2005 The Air-Conditioning and Refrigeration Institute has established ARI Standard 550/590-98, which is a standard for water chilling packages using the vapour compression cycle. It states that the leaving chilled water temperature should be 44oF at 2.4 gpm/ton and the entering condenser water temperature should be 85oF at 3.0 gpm/ton.

What Are the Benefits of Water-cooled Chillers?

May 17, 2022 Water-cooled chiller systems have cooling towers, so they are more efficient than air-cooled chillers. Water-cooled chillers are more efficient because their condensation depends on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature. ...

May 20, 2022 Figure 8 shows the effect of hot water flow rate on the chiller’s average cooling capacity and COP, while Figure 9 shows the effect of hot water flow rate on the hot water outlet temperature. The optimum hot water mass flow rate is 1.5 kg/s, which gives a maximum average cooling capacity of around 8 kW and a maximum COP of 0.26.
