Problems solved by technology

[0002] The chiller can be used as the host of the central air-conditioning system. At present, the chiller usually controls the frequency conversion of the water pump that drives the cooling water to achieve energy-saving control. However, after the frequency conversion of the water pump, the compressor of the chiller may run in a non-energy-saving range.

Abstract

The invention discloses a control system, a control method and a water chilling unit using the control system and the control method. The inlet water temperature and the outlet water temperature of a heat exchanger of the water chilling unit and heat exchanger parameters for calculating a heat transfer average temperature difference are detected, the frequency of a water pump and the load of a compressor are cooperatively controlled on the basis of the parameters, and therefore the water chilling unit can be kept in the overall energy saving operation state in any working condition.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a control system, a control method and a water chiller applying the same. Background technique [0002] The chiller can be used as the host of the central air-conditioning system. At present, the chiller usually controls the frequency conversion of the water pump driving the cooling water to achieve energy-saving control. However, after the frequency conversion of the water pump, the compressor of the chiller may run in a non-energy-saving range. Contents of the invention [0003] In view of this, the present invention provides a control system, a control method and a water chiller using the same, so that under any working conditions, the water pump and the compressor are coordinated and controlled, and the whole unit is in an overall energy-saving operation state. [0004] In the first aspect, a control system of a chiller is provided, including: [0005] The water inlet tempera...
