To protect the environment, a new low-GWP refrigerant R1234ze(E) was created to substitute R134a. However, its flow boiling performances have not received sufficient attention so far, which hinders its popularization to some extent.

Comparison of two surface temperature measurement using thermocouples and infrared camera
This paper compares two methods applied to measure surface temperatures at an experimental setup designed to analyse flow boiling heat transfer. The temperature measurements were performed in two parallel rectangular minichannels, both 1.7 mm deep, 16 mm

Refrigerant R32 as lower GWP working fluid in residential air conditioning systems in Europe and the USA [PDF]
Because air conditioning and heat pump systems contribute greatly to greenhouse gas emissions, equipment with both lower global warming potential (GWP) working fluids and a higher level of performance should be used.

Boiling of Subcooled Liquid in a Flat Minichannel with a Graphene Coating [PDF]
Boiling occurs in many energy technologies, including thermal stabilization systems, where heat is removed from the wall due to the latent heat of vaporization of the coolant. Applying coatings to the heat-generating surface is one of the ways to enhance
