### Water Chiller: What Is It? How Does It Work? Types, Uses

A water chiller, or chilled water system, is a type of refrigeration system which uses water as a secondary refrigerant. They are used for larger, more complex, heating, ventilating, air conditioning, and refrigeration (HVACR) applications. A water chiller is composed of two main loops or circuits: the refrigeration loop and the chilled water loop.

### Calculating the Heat Generated by a Recirculating Chiller

How to Calculate the Heat Generated by a Recirculating Chiller. The way you calculate the heat generated will depend on one important factor: the type of condenser the chiller uses. Air-cooled condensers will release heat into the air rather than transferring it to the facility water as do water-cooled condensers.

### Chiller Capacity Calculation - Water Chilling Systems

To calculate the power we must know the mass flow that the chiller will receive, for this we use table 2: Chiller water flow = 18 m3 / h. With table 4 we have: 18 m3 / h x 16.67 = 300 Liters / minute = 5 Liters / second. Chiller Power = Total Heat X Mass Flow. Mass Flow = Volumetric Flow X Density. Mass Flow = 0.5 l / s X 1 Kg / l = 5Kg / s.

### How to Calculate Chiller Efficiency | Hunker

Step 2. Calculate the chiller capacity in tons of refrigeration. The formula for total heat removed in a chiller installation is h = 500 X q X dt where h = total heat removed in Btu/hr, q is the chilled water flow rate in gpm, and dt is the chilled water' total temperature differential. Substituting, h = 500 X 40 gpm X 24 deg-F = 480,000 Btu ...
