Abstract

The invention discloses a control method for an air conditioner water system and a control device for the air conditioner water system. The control method comprises the steps that the set differential pressure of the air conditioner water system is obtained as the first differential pressure; the actual differential pressure of the air conditioner water system is obtained as the second differential pressure according to the preset time interval; if the second differential pressure is different from the first differential pressure, the set differential pressure is adjusted to the second differential pressure; and a water pump in the air conditioner water system is controlled according to the second differential pressure. By means of the technical scheme, the control method and the control device are used for solving the technical problem of the high energy consumption existing in the air conditioner water system in the prior art.

Description

technical field [0001] The invention relates to the field of air-conditioning energy-saving control, in particular to a control method and a control device for an air-conditioning water system. Background technique [0002] At present, in large-scale commercial and civil high-rise buildings, the energy consumption of the central air-conditioning system accounts for about 60% or even higher of the energy of the entire building. Therefore, higher requirements are put forward for the high-efficiency operation and energy-saving design standards of the air-conditioning system. [0003] The energy consumption of the central air-conditioning system mainly comes from the operation of the transmission and distribution system. Therefore, the energy saving of the transmission and distribution system is getting more and more attention. The system transformed by the frequency conversion of the water pump can save a lot of electric energy, but the situation that often occurs after the tra...
