Experimental and theoretical investigations of a telecommunication cabinet cooling mode with zero electrical consumption

This paper presents experimental investigations on a real Orange telecommunication cabinet cooled using a special designed cooling loop in order to increase its maximum operating power limit and reduce its electrical consumption. The proposed cooling loop is an innovative development in the telecommunication cabinets cooling field since it operates without electrical consumption. Different condenser types are tested on the loop, where their effects on the loop performance are investigated. Increasing of the working fluid fill charge enhances the evaporator performance.
