Abstract

The invention provides an air conditioner cooling water system comprising a cooling tower, a cooling water outlet pipe and a cooling water returning pipe. The cooling water outlet pipe and the cooling water returning pipe communicate with the cooling tower. The air conditioner cooling water system is used for utilizing cooling water in the cooling tower to exchange heat with a condenser and characterized by further comprising an auxiliary heat exchanger and an auxiliary switch; the auxiliary heat exchanger is used for cooling inlet air of the cooling tower; and the auxiliary switch is used for controlling the working state of the auxiliary heat exchanger. The air conditioner cooling water system is provided with the auxiliary heat exchanger, the inlet air of the cooling tower is cooled by utilizing the auxiliary heat exchanger, and accordingly the water outlet temperature of the cooling water of the cooling tower is decreased. When the outdoor wet bulb temperature is low, the water outlet temperature of the cooling water of the cooling tower can be decreased with the outdoor wet bulb temperature synchronously or further decreased below the outdoor wet bulb temperature, the energy efficiency of the air conditioner cooling water system is improved, and energy waste is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment design, in particular to an air-conditioning cooling water system, an air-conditioning system and a control method for the air-conditioning cooling water system. Background technique [0002] Traditional air conditioning cooling water systems generally have the following deficiencies: when the outdoor wet bulb temperature is low, due to factors such as selection and control of the cooling tower, the cooling water outlet temperature cannot be reduced synchronously with the wet bulb temperature, and the traditional high-efficiency variable frequency cooling water system When the cooling water inlet temperature is low, the energy efficiency will be greatly improved, but if the cooling tower outlet water temperature cannot be lowered synchronously with the wet bulb temperature, it will lead to a large energy waste in the frequency conversion cooling water system.
