AN AIR CONDITIONING EQUIPMENT FOR ENVIRONMENTAL-FRIENDLY ENERGY SAVING

PURPOSE: An energy saving type air conditioning system is provided to control air volume according to constant pressure by installing a constant pressure sensor in the front or rear part of a fan installed on and connected with a BLDC motor, and to reduce loss of energy by controlling a minimum amount of outside air. CONSTITUTION: An energy saving type air conditioning system includes a CO2 detection sensor(146). A CO2 detection sensor is installed on one side of an air exhaust chamber(138) and is electrically connected with a control panel for control, thereby sensing CO2 from stored air in the air exhaust chamber according to a control signal of the control panel for control. A second and a Nth BLDC motor(142-2)-(142-N) control air volume of a fan by controlling voltage according to change of pressure. A constant pressure sensor is electrically connected with a control panel for control capable of controlling air volume by sensing a revolution speed of a fan according to a control signal of the control panel for control is further installed.
