How to calculate water consumption in a chiller - Quora- water chiller calculation ,Answer (1 of 3): You question needs clarity. Basically water is used in two points of a chiller. Namely chiller side and condenser side, if its a water cooled chiller.

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.
That calculation is for the water side only, not accounting for the type of equipment doing the cooling work, or its efficiency. Normally, you see the specs of the chiller, then you see whether or not it is able to cool the water as needed by the system.
This guide covers the overall chilled water system, the calculator and the chilled water pump schedule. The overall chilled water system will help you to visualize how the chilled water pump fits within the overall system and will also help you to determine the hydraulically remote run for pressure drop calculations.
I- Evaporative chiller: Evaporative chillers are classified according to: Condenser cooling: 1- Water cooled evaporative chiller. 2- Air cooled evaporative chiller. Condenser location: 1- Package chiller. 2- Remote condenser chiller. Compressor type: 1- Positive Displacement (Reciprocating). 2- Centrifugal (Rotary Screw and Scroll). II ...
Water treatment is very important for Chilled water air conditioning system. It reduce corrosion through the water pipe network. The amount of water treatment chemicals and the capacity of dosing station depend on the volume of Chilled water volume through all the pipe network. With this excel sheet you be able to calculate this volume in gpm.
Example - Water Chiller Cooling. Water flows with 1 gal/min and 10oF temperature difference. The ton of cooling load can be calculated as: h = 500 (1 US gal/min) (10 oF) = 5000 Btu/h. = (5000 Btu/h) / (12000 Btu/ton) = 0.42 ton. Converting between heat and energy units.
1. Touching the inhaler and exhaust pipe to sense the heat and cold of the copper pipe. 2. Observe the bubbles in the retinoscope. 3. Measuring high and low-pressure pressure. 4.Measuring the current of the compressor. 5.Calculate the superheat. 6.Calculate the subcooling degree.
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.
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.
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 ...
Help. Move a slider to your specified cooling requirement (Qc) and click the SEARCH button. As you move the slider to the right, multiple product categories may offer suitable standard solutions. You will see multiple sliders moving simultaneously at this time. The optimum thermal management solutions will display below the sliders.
Using the window sensible cooling load formula: q = A (GLF) q = (2.25 x 104) + (3.6 x 158) q = 802.80 W. Therefore, the sensible cooling load of the windows in my bedroom is 802.80 W. Now, let' proceed to calculate the sensible cooling load for doors. 2. Doors Sensible Cooling Load Calculation.
Water Cooled chiller is required to run at 44 Deg. F evaporator Leaving water temperature with a flow rate of 2.4 GPM/ Ton. The condenser entering water temperature will vary depending on the part load capacity utilizing a 3 GPM/Ton flow rate, and 85 Deg. F at 100 % Load. For More Posts Related To HVAC .

You can generally calculate it using this formula: Calculate Temperature Differential (?T°F) ?T°F = Incoming Water Temperature (°F) - Required Chill Water Temperature Calculate BTU/hr. BTU/hr. = Gallons per hr x 8.33 x ?T°F Calculate tons of cooling capacity Tons = BTU/hr. ÷ 12,000 Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2
Example: process chiller flowing about 50 GPM with a 10 degree split between return and supply water... 500 x 50 x 10 = 250,000 BTUH. 250,000/12,000 = 20 tons. Assume machine is drawing 12 kilowatts to achieve this output: 12 kilowatts/20 tons = .6 kilowatts per ton.
