Performance experiment of heat pipe type air conditioning units for computer and data processing rooms

Presents the operating principle and technical features, and performs the experimental research on the heat pipe type air conditioning. The results show that the unit can be run to carry total or partial cooling loads of the machine room with high energy efficiency ratio when indoor and outdoor temperature difference is above 5 ℃, and the energy efficiency ratio of the units can be as high as 3.63 to 10.64 and the temperature efficiency 65.6％ to 44.0％ when the temperature difference is 5 to 24 ℃. The units can save energy remarkably by substituting the vapor compression-type refrigeration machines in winter.
