Abstract
The utility model discloses an energy-saver of central air conditioner. The utility model is an energy-saver in the central air conditioning system by means of temperature regulation with cold water. The technic propose is that a sensing apparatus connected with a central microprocessor transmits via a feedback apparatus the signals monitored by the sensing apparatus to the central microprocessor, the other end of which is connected with a frequency converting apparatus, to instruct the electric machine to regulate the output power. Therefore, the central air conditioner puts out the needed flow capacity of refrigerant on basis of the actually required load at the terminal of the air conditioning system. As the actual output power of the air conditioning system is identical to the needed flow capacity at the terminal of the refrigerant so as to insure the actually required load at the terminal of the flow capacity of refrigerant and reduce the overall output of electric energy by a large margin, hence a saving rate of electric energy from 20 to 50 percent.
