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.
R32 is one of the more recent refrigerant gases, used mainly in air-conditioning. Up until a few years ago it was considered a major step forward in the battle against global warming, but recent findings about the state of the earth’s atmosphere have led Europe to take steps to protect itself through various new legislation.
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 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.
Across the world there are over 600 million hydrocarbon domestic refrigerators. Let’s find out what hydrocarbons are and why they are so widely used
