UNILAB PCOIL is the Unilab continuous (Steady State) software to design and verify Pillow Plate Banks. PCOIL is divided by applications types in several calculation modalities.
With its wide array of calculation modes, PCOIL allows Energy Recovery calculations, ranging from applications with gas external to the pillow bank, to steam that condenses, to vaporizers using exhaust gas to createsteam. The Falling Film Chiller module, fluid-fluid or DX, uses specific conduction equations allowingto calculate the film thickness as a function of flow rate, size and distribution on the plates, and asa function of this thickness, to calculate the heat transfer coefficient. Air heaters, used for examplein seed heating, and Air Coolers applications, complete the Pcoil module.
Currently, our PILLOW SUITE, like all UNILAB Software, has a wide library of fluids.
All PILLOW SUITE software use the library REFPROP of NIST (National Institute of Standards and Technology). It comprises the thermodynamic and thermophysical properties of more than 300 liquids & gases, and 12 mixtures of liquids, including the newest refrigerants like R1234ze, R1234yf, R449A, a wide variety of Oils and many more.
Our calculation models are supported by almost 35 years of research & expertise.
Ready-made projects are available in each mode, to help the user perform the calculation. The equations of PILLOW SUITE are among the most modern from the point of view of literature publications. Through calculation factors, thesoftware gives the possibility to the user to align the theoretical result with his experimental data.
