A method for regulating and controlling energy-saving operation of a chiller machine

A method for regulating and controlling energy-saving operation of a chiller machine, comprising the following steps: establishing the relationship between the amount of low-pressure steam and the temperature of ice water, establishing a relationship model between the water temperature at the outlet of the chiller machine and the amount of steam; analyzing the energy calibration of the chiller machine, and calculating the coefficient of performance of the chiller machine; Estimate the amount of low-pressure steam and calculate the amount of low-pressure steam required; calculate the compensation amount of medium-pressure steam, when the amount of low-pressure steam required is insufficient, reduce the amount of low-pressure steam required to achieve the required amount of low-pressure steam; and compensate according to the medium-pressure steam In order to maintain the high energy efficiency of the chiller unit and avoid the oversupply situation, the adjustment logic is designed and adjusted according to the
