Cool Pack Refrigeration Software Download
Can you design your own refrigeration system? Take the guess work out of your designs.Thisprogram will find the balance point between compressor, evaporator andcondenser.
In addition, it will show you the process on the refrigerantln(P)-h diagram and do a step-by-step simulation of the coil performance.If you are a manufacturer or contractor who builds systems, then you willfind this program essential. It is easy to specify the system componentsand the design conditions. Press the solve button and you have the exactduty. No guessing or assumptions needed.The solution is clearly based on the design conditions so by using the RefSimprogram, you can calculate the actual solution at design and part-loadconditions.To do this manually, you will need to plot the condensing unit curve fordifferent ambient temperatures. Next, superimpose the evaporatorperformance curve. The intersection between the two is the balance point.This process is quite a mission and explains why its not often donecommercially. If you want to see the step by step process in detail, seeStoecker & Jones 'Refrigeration and Air Conditioning'.We have adopted the numerical approach which is clearly better suited tomodern computer techniques.

There are three main components (Compressor, Evaporator and Condenser). All you need to do is solve thesimultaneous equations for the two unknowns, evaporating temperature andcondensing temperature.Oneof the features of this program is that it shares information with otherprograms. There are two coils in an air cooled system. These coilscan be found in our library.Select a CompressorThe compressor can be selected from a compressor selection expert.In this form you can enter the evaporating and condensing temperatures andbrowse through the database. As you do this, the duty of the compressor iscalculated at specified conditions. How's that for a time saver?

Iremember manually hunting through my various catalogs for a suitable compressor.The problem with the paper catalog is that you have to manually interpolate tofind the duty.This compressor selector takes proper account of the superheat and thesub-cooling of the selected compressor since the reference conditions are storedin the compressor database.If you would like me to add a specific compressor to the database, send me anemail or post a message to the ofthis web site.Once you have a system balance, all that remains is to selectand the TX Valve or the. The program has a buildin refrigerant line size calculator.
Just click on the refrigerant line onthe schematic and the line size dialog will appear.RefSimis actually more than it appears to be on the surface. I am using aprogramming technique called polymorphism, where the program can take ondifferent roles depending on the components. This fits in very well withthe refrigeration cycle that is created with abstract heat exchangerdefinitions. By delaying the definition of the heat exchangers untilruntime, it is possible for the program to take on different roles. Theone shown above is a conventional air-cooled package air-conditioner.
Nowconsider changing the evaporator to a shell & tube heat-exchanger and we have anair-cooled chiller.Since the cycle solve methods are independant of the heat-exchangers, thisallows the development of any type of cycle, simply by applying a specificheat-exchanger model.In a similar way, we define a water-cooled chiller and an evap-condensercooled chiller.The heat pump can be found commercially from any number of manufacturers.Actually the cycle is identical to the refrigeration cycle, the definition issimply which heat exchanger is the required energy control. So, if the need isfor heating, you would want the air cooled condenser coil indoors.
CoolPack was developed by the, Section of at the Technical University of Denmark (DTU). The development of CoolPack has until version 1.33 been financed by the Danish Energy Agency as part of the SysSim project. IPU hosts the CoolPack download pages.The following simulation purposes are covered:.
Cycle analysis (process design). System sizing. System simulation. Component calculations. Analysis of operating conditions. Transient simulation (cooling of an object/room).
Refrigerant calculations (property plots, thermodynamic & transport properties, comparison of refrigerants). Life cycle cost (LCC)As indicated by the name, CoolPack is a collection of simulation programs related to refrigeration. It consists of “Refrigeration Utilities”, “EESCoolTools”, and a transient element called “Dynamic”.The first version of Refrigeration Utilities was released in 1995 and the program has since then been updated continuously with new refrigerants, more property plots etc.EESCoolTools has been formally introduced as part of CoolPack (March 1999). The name EESCoolTools is a combination of the three words EES, Cool and Tools:. “EES” refers to the name of the program used to develop the simulation models (Engineering Equation Solver – EES). “Cool” refers to that the programs are related to the area of refrigeration. “Tools” refers to that the programs are thought to be tools enabling you to make faster and more detailed system design and energy analysis.EES is developed by S.
Klein and F.L. Alvarado, and is sold by F-Chart Software in Wisconsin, USA. You can get more information about EES and on the Internet.The dynamic elements are modeled and solved using a DAE-type simulation program called DALI. DALI was developed at the Refrigeration Laboratory (now part of Section of Thermal Energy at the Technical University of Denmark) in 1985. Originally, it was programmed in Pascal but the present release is updated to Delphi. So far we have included one transient element: simulation of the cooling of an object with the possibility of applying an on/off control of the compressor.
