Alfa Laval produces high-quality air heat exchangers for the refrigeration market. These products are used for cooling, freezing and air conditioning applications.
This easy-to-use Cold Room Calculator, based on common refrigeration practise, quickly calculates the required cooling capacity for cold rooms in cooling and freezing conditions.
Enter your installation data in the four tabs: temperature data, cold room dimensions, isolation, heat loss and stored products. Then select the Calculate tab to instantly see the calculation for your installation. You can send the data and calculations in an e-mail to yourself or clients.
Wether you have existing radiators and want to check that they are the correct size or if you are adding a new radiator to a room; this is the application for you.
The simple yet intuitive interface allows you the choice of measurements in feet or meters.
This calculator has the added benefit of showing you the BTU required and also the kW required.
Features that can be adjusted for the BTU calculation include:
Foam-filled or uninsulated cavity walls
2 or 3 outside walls
Units of measurement
Device Requirements :
Android 2.2 or higher
Adobe AIR 2.5 (free download)

Shows the benefits of purchasing higher efficiency equipment.
Prepares a load calculation report to obtain a permit.
The EMS load calculation app has been developed using sound engineering principles as prescribed by ACCA's Manual J and ASHRAE's "Handbook of Fundamentals".
The only HVAC load calculation app designed exclusively for the change-out market. Contractors, salespeople and service technicians can perform a load in minutes to determine the correct equipment size and show the customer the financial benefits of moving up to higher efficiency equipment.
Once a load calculation is performed it may be stored on your android device and given to your customer or permitting department via e-mail or printed.
No other load calculator app offers as many features at such a great price:
• Performs whole house heat gain and heat loss calculation (Block Load) for any location on earth
• Blower door results may be entered
• Window manufacturer's specs may be used
• Any R-value may be entered for walls, floors or ceilings
• Multiple duct configurations, locations, insulation values, and leakage rates may be selected
• Estimates and compares operating cost of one system to another (using natural gas, oil, LP gas, heat pump or electric resistance heat)
• Gives return on investment
• Shows payback
• Play "what if" when adding insulation, changing efficiencies or energy sources
• Prints or emails a PDF report to submit with your permit application or include in your proposal

Get rid of the advertisements by buying the General Engineering (Paid) version.
This free version has STOPPED adding calculation modules. It will only fix any possible bugs.
New modules are ONLY added to the paid version.
Any positive constructive critique is welcome. And if you want more modules to be added, we'll be very glad to do so.
But please concentrate on important hard-to-follow formulas when calculating manually. This application is meant to ease calculations without getting lost between the variables of the engineering equation or formula.
Please write the review in either English or Arabic. The computer translation is weak.
Please read the description till the bottom. It's important.
In this application, You can send the calculation results via:
- Email (at least get Gmail client for Android installed)
- Skype (if installed)
- SMS (The usual classic mobile messaging).
The application covers the following topics:
A table of units.
A table of physical constants.
Forward and backward conversion between units (more than 50 conversions).
From applied maths for engineers:
1- Geometry area and volume.
2- Finding the location of centroids of important shapes.
3- Finding the roots of 2nd,3rd,4th, and 5th degree equations with complex roots too.
From electrical and electronic engineering:
1- A module for Ohm's Law . It helps you find either Power,Resistance, Intensity, or Voltage.
2- Resultant sum of either of Resistances, Capacitors, or Inductances whether they are in series or in parallel. you can have up to 10 elements (which is more than enough)
3- A module to find the change in the value of the motor resistance of the wire windings after getting some heat through runtime
4- Voltage Drop
5- Resistance value using colour codes
6- Wheatstone Bridge
7- Butterworth Tee LC Filters (High pass and Low pass)
8- Chebychev Tee LC Filters (High pass and Low pass)
9- Butterworth equal component Filters (High pass and Low pass)
10- Pi attenuator
12- Helix Antenna Design
13- Battery life
14- BJT Transistor Bias Voltage Calculation
15- Non-inverting op-Amp resistor
16- Zener diode
17- Radar Range
From Mechanical Engineering:
1- Resultant sum of two forces acting at the same point
2- Using the altitude and the latitude given by the GPS in the phone, find the exact value of the gravitational acceleration of the earth.
3- Rectangular Beam Deflection (hollow and solid)
4- Round Beam Deflection (hollow and solid)
5- Internal screw thread shear area
6- External screw thread shear area
7- Cam-with-follower Profile determination. here you can see both the coordinates of the profile of the cam on a step of 1 degree only, and get the profile plotted so you can see how it would look like.
The following are Functional ONLY in the Paid version
*- Light Lux meter
*- Shear and Shear Force
*- Cartesian Fluid Flow Analysis.
*- Beams : Moment of inertia+Section Modulus+Radius of Gyration.
*- Beams : Stress & Deflection studies.
*- Interpolation on Saturated Steam Tables
*- Heat transfer through walls.
*- Heat loss from pipes wrapped with insulators.
The application uses GPS. It's used only in taking the coordinates for the sake of calculations. If you are in doubt that we might steal your coordinates, you can use the manual input option. You have been warned. Thanks.-*
