A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

How can you tell when a system is low on refrigerant? Running a system check can determine whether that’s the case. Consider this scenario: A service technician installs gauges and thermistors on an R ...

Japanese technology companies NEC and NTT Communications have teamed up to engineer a system to cool data centers using less energy than any other, using a new low pressure refrigerant. The cooling ...

As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have ...

The processes governing condensation in refrigerants are critical to modern thermal management and energy systems. Condensation heat transfer, which involves the phase change from vapour to liquid, ...

In the spring and early summer, many homeowners will seek the advice of an air conditioning expert for some routine maintenance before the extreme summer heat ramps up. It’s not uncommon to hear a ...
