Example Embodiment

[0039] If an integrated refrigeration device and cooling tower are used, it is usually only thought of using water cooling or air cooling in the cooling tower to directly cool the high temperature refrigerant medium circulating in the condenser of the refrigeration device. However, because the process fluid medium cooled by the cooling tower is a high-temperature refrigerant medium, which is of a different quality from the cooling medium used in the chilled water circulation system, it is impossible for the process fluid medium cooled by the cooling tower to be switched into the chilled water circulation system. When there is a usable temperature difference between the air-conditioning environments, for example, when the outdoor temperature is much lower than the indoor temperature, the natural cooling source cannot be fully utilized to achieve energy saving.

Abstract

The invention provides an energy-saving air conditioner water chilling unit and an energy-saving air conditioning system. The energy-saving air conditioner water chilling unit comprises an integrated refrigerating device, a cooling water circulation system and a cooling device. The cooling device is used for evaporative cooling for a heat exchanger in the cooling water circulation system by means of air cooling or water cooling. The energy-saving air conditioner water chilling unit further comprises a chilled water connector used to establishing a chilled water circulation system. Same circulating cooling media flow in the cooling water circulation system and the chilled water circulation system. A cooling water pipe is provided with at least two energy-saving conversion connectors used for selective switching. Therefore, during utilization of natural atmospheric temperature, the low-temperature cooling medium obtained in the evaporative cooling of the heat exchanger of the cooling water circulation system can be pumped by a chilled water pump and is directly switched to enter the chilled water circulation system, a cross-system homo-medium closed circulation is formed, and a cooling required environment is directly cooled when the refrigerating device stops running. Natural cold sources are fully utilized for switchable operation of cooling, heating and heat recovery, and accordingly evident energy saving effect is realized.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy-saving air-conditioning chiller and an energy-saving air-conditioning system. Background technique [0002] At present, traditional air-conditioning chillers at home and abroad are generally arranged separately from the cooling device and the cooling tower (or cooling device). Water pipes and the necessary powerful pumps consume a lot of energy. When there is an available temperature difference between the natural temperature of the atmosphere and the air-conditioning environment of the building, for example, when the outdoor temperature is 5°C lower than the indoor temperature, there is no technical condition for a water system that is flexible and fully utilizes the natural cooling source to achieve cooling. The limitations of tower split operation technology. Contents of the invention [0003] Features and advantages of the invention are set forth in par...
