Coils Calculator. The main function of Coils selection module software is to calculate the performance of tubes and fins heat exchangers. It uses a fast, tested and effective calculation engine to provide the performance for monophase coils, direct expansion coils, refrigerant condensers coils and steam coils. Basic functions for coils selection.

Inductance. Note that when doing calculations for a coil with very thin wire as with the crystal radio and the Tesla coil shown above (e.g. 24 gauge/AWG) then the size of the wire will probably be negligible compared to the area of the core and you can usually ignore the wire.

To solve the performance of refrigeration systems, you will need to calculate the performance of the direct expansion and air cooled condenser coils. All of the coil types are designed to exchange heat between some fluid and air. The direct expansion coil is a refrigerant coil that is used to cool air.

Excel Template - Page 1: Calculation of Heat Transfer Area. After values are entered for those parameters the Excel formulas in the spreadsheet will calculate the heat transfer rate, the log mean temperature difference, the required heat transfer area, and the …

Aug 01, 2013· Design of condenser. DESIGN CALCULATIONS FOR CONDENSER • Inlet temperature of the process stream 'T1' = 45 o C • Outlet temperature of the process stream 'T2' = 45 o C • Inlet temperature of the water 't1' = 25 0 C • Outlet temperature of the water 't2' = 40 o C • Mass flow rate of the process stream 'm' = 8060 Kg/hr • Enthalpy of Vapors.

Aug 28, 2011· Coil Size calculation Can anyone suggest me how to calculate size of condenser size of ductable unit of 8.5 tr capacity at 54.4 deg condensing temp & 7.2 deg evap temp

Nov 23, 2013· Re: evaporative condenser coil design calculation You would normally use circulating water in an evaporative condenser, with a shell and tube or plate heat exchanger on the chiller. Brian - Newton Abbot, Devon, UK

Here's a Calculator to Help You. If you want water to enter the evaporator at 60 degrees Fahrenheit and leave at 46 degrees Fahrenheit: 60 - 46 = 14. Multiply the answer by your proposed volumetric flow rate, measured in gallons per minute. If the evaporator must move 400 gallons per minute: 14 x 400 = 5,600.

In general, condensers and evaporators for refrigeration applications are designed considering the coil flooded with two-phase refrigerant, and also a wall temperature close to the refrigerant temperature (Barbosa and Hermes, 2012), so that the temperature profiles …

Feb 14, 2013· Today we are going to show how to perform a condenser rating with Unilab Coils(.unilab.eu/prodotto/unilab-coils/). For more info about UNILAB pleas.
