Experimental study on heating efficiency of wall surface using vertical wall-attached air jet

Aiming at the wall surface condensation in the basement, carries out an experimental research on the heating efficiency of the wall surface using vertical wall-attached air jet to prevent the condensation on the wall. The test results show that the better effect of wall heating is achieved when the air supply angle is 0° and the optimal value of horizontal distance between the wall and the air diffuser is 5.0 cm.
