We are pleased to announce you that Build 191011 of COILS is available to download for users under regular tech support. We have modified the Coils DLL calculation engine to introduce ADP (Apparatus Dew Point temperature) and bypass factor formula based on the work of R V Simha and Australian airah (airah.org.au) – see sources for info.
Unilab is proud to announce its partnership with the MUAS – The University of Applied Sciences – Hochschule für angewandte Wissenschaften in München, which now uses our state of the art UNILAB COILS software, since October 2019.
Unilab is proud to announce the update of the Unisuite calculation DLL to include the latest refrigerants in the Refprop library. Our programs PHE, SHELL, TUBE IN TUBE, and COAX are now including our latest calculation DLL, and new refrigerants have been added, like R1234ze, R1234yf, R448A, R449A, R450A, R513A and many more.
A successful refrigeration system depends on good refrigerant line design. Let’s find out more in this technical article!
Microfin tubes are widely used as enhanced surfaces: but are they always convenient?
Let’s close this brief analysis of Heat Pipes with this 3rd technical article on heat transfer limits
In a previous article we introduced and described, from a general point of view, the Heat Pipes. Now, we want to present some general aspects concerning on the operating principles of these devices.
The heat pipe is a device of very high thermal conductance. Let’s find out the story and characteristicst behind this particular type of heat exchanger
The decision to purchase a Shell and Tube Heat Exchanger (Tubular Heat Exchangers) or a Plate Heat Exchanger is usually very complex.
The application of fluids with nanoparticles in refrigerating systems is potential way to improve the energy efficiency and reliability of HVAC&R facilities
Read about the substitution of the condenser with a gas-cooler, where the carbon dioxide is cooled without phase change process.
Carbon dioxide was widely used in refrigeration machines before being substituted by CFCs. Read why it’s coming back in fashion.
