Highly effective energy-conserving control system of central air-conditioner

The utility model is an improvement design for the central air-conditioning high-efficient energy-saving control system. The improved system structure includes an on-line regulation management circuit composed of a refrigeration water circulating system, a cooling water circulating system and a signal processors. The regulating signal is transmitted from the signal processor to the frequency converter. The refrigeration water inlet and outlet pipes connected with the central air-conditioning main unit are respectively provided with a refrigeration water inlet temperature sensor, a refrigeration water outlet temperature sensor and a refrigeration water flow meter. The cooling water inlet and outlet pipes connected with the central air-conditioning main unit are respectively provided with a cooling water inlet temperature sensor, a cooling water outlet temperature sensor and outdoor temperature and humidity sensor. The signals collected by the sensors are transmitted to the signal processor through the signal c
