This calculator helps you determine the scaling potential of the water by using the Langelier Saturation Index. Give the values of your water analysis. All the fields with are required. If you do not have a water analysis you can use the values in table 2. Click on a button at the bottom of table 2. For an explanation of the formula click. Heat Load BTU/Hr = GPM X 500 X Range of cooling, or rearranged to determine the design flow rate. GPM = Heat Load BTU/Hr = 6,250,000 Btu/Hr = 835 gpm 500 X Range of cooling 500 x 15 R Now you can make your cooling tower selection based on 835 gpm, cooling from 98F to 83F a design 76F Twb.

In cooling towers with well-engineered mist eliminators, a common design drift rate is 0.0005 of the circulating water flow rate. So, for our example drift would amount to approximately 1 gpm. 10:15 11:00 Cooling Tower Energy Efficiency 11:00 12:00 Cooling Tower Water Savings 12:00 12:30 Chiller Efficiency 12:30 1:30 Lunch 1:30 2:15 Kitchen Ventilation 2:15 3:00 Garage carbon monoxide CO demand contro l ventilation 3:00 3:15 Break 3:15 4:00 Variable air volume VAV labs and fume exhaust.
PDF 7. COOLING TOWER - Bureau of Energy Efficiency.
Cooling Technology is a broad industry association, our mission is to advocate and promote, for the benefit of the public, the use of all environmentally responsible cooling technologies such as wet cooling towers, air-cooled condensers, dry coolers, indirect cooling, and hybrid systems. A chemical plant operates a mechanical draft cooling tower circulating 3,650 million gallons for the year of water to cool down process stream. Source test indicated 0.2 Nickel present in the PM emissions from the cooling tower. Facilities are required to report their VOC, PM, and TAC emissions from the cooling tower using the new AER web program. Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space.
PDF BUSINESS EFFICIENCY PROGRAM Cooling towers FACT SHEET.
A Cooling tower is an essential piece of equipment in many production facilities used to bring down the temperature of the water used in many different proce. A cooling tower is a counter-flow or cross-flow heat exchanger that removes heat from water and transfers it to air. Cooling towers come in many configurations. An induced-draft cooling tower, which is common in HVAC and industrial applications, is shown in Figure 1. As warm water from the process falls through the tower, some of it evaporates. Measures that are available for cooling towers. The weaknesses of the current model are demonstrated and prediction capabilities of the new model analyzed and validated. Further the economic feasibility of having additional cooling tower capacity to allow for economizer cooling, in light of reduced tower capacity at lower temperatures [3] is.

T i = water inlet temperature #176;c or #176;F T o = water outlet temperature #176;c or #176;F T wb = air web bulb temperature #176;c or #176;F Some orders of magnitude The difference of temperature in between the inlet and outlet temperature is usually around 5-8c.
Cooling Tower Water Loss Calculator - C.
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of dry cooling towers, rely solely on air to cool the working fluid to near the. Use this handy calculator to approximate cooling tower water use and cycles of concendtration. Remember, TRS can help with water saving designs and treatment systems. Please update the following information as it applies to your tower needs. TOWER DESIGNER amp; SELECTOR is an advanced design and selection software for open and closed circuit cooling towers, used in HVAC amp; R systems and industrial processes. MODULS.

The standard formula is, DT = Temperature difference range between the warm and cooled circulating water F f average is often considered to be 0.65 to 0.85, but will rise in summer and.
Cooling Load Calculation - Cold Room - The Engineering Mindset.
Nov 22, 2014 The quot;Cooling Tower Softwarequot; program is based on these two flow patterns managed by the cooling tower. This calculating program has three functions and it can be used for: i designing a new project, ii upgrading the performance of an existing counter flow tower, and. iii verifying the efficiency and working conditions of a tower.
Wet-cooling tower performance evaluation software.
Number represents and why those cooling tower, the product is cold particular values are significant? water leaving the tower and ambient wet bulb is the driving force that creates the cold water. If a cooling tower produces 85F cold water when the ambient wet bulb is 78F, then the cooling tower approach is 7F.
