Inspecting building insulation, HVAC systems and refrigeration units with thermal imaging

Oct. 2, 2016 “Building inspectors have been using FLIR thermal imaging cameras for energy audits for decades, but the investment cost prevented many building and installation companies from buying one. In recent years increasingly affordable models have entered the market. One of the building professionals that leaped at the opportunity is Björn Blomgren of the […]

Refrigerants & Basic principles for selection of refrigerants

A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again. Many working fluids have been used for such purposes. Fluorocarbons, especially chlorofluorocarbons, became commonplace in the 20th century, but they are being phased out because of their ozone depletion effects. Other common refrigerants used in various applications […]
