Household air conditioning gas freon r-22Refrigerant gas r22 is a colorless,non-toxicnon-flammable and transparent liquid under the pressure created by itself. It has excellent thermal and chemaical stabilities and no corrosivity to metals.Its main applications include refrigerant(-...
Condensation heat transfer and pressure drop of R22 and R410a were investigated experimentally in a single round stainless steel tube with the inner diameter of 0.941mm. The effects of mass flux and vapor quality were analyzed and the results indicated that local condensation coefficients increase ...
