Description

Energy-saving central air-conditioning

technical field

The utility model relates to the technical field of air conditioners, in particular to an energy-saving central air conditioner.

Background technique

The conventional water-cooled central air-conditioning system uses cooling water to cool the heat generated after the refrigerant is compressed into the condenser. In order to dissipate the heat of the condenser, the air-conditioning system is usually equipped with a circulating water pump and a cooling tower. The circulating water in the condenser passes through the circulating water pump and The cooling tower is connected. During operation, the circulating water pump can discharge the heat generated by the refrigeration compressor to the atmosphere through the cooling tower to reduce the temperature of the refrigerant in the condenser and ensure the normal cooling of the air conditioning unit.

In the context of global water resource stress, especially as my country is listed as one of the 13 countries with poor per capita water resources in the world, saving water and recycling water is of great significance to our country. Since the heat of the condenser of the conventional water-cooled central air-conditioning system is pressed to the cooling tower by the circulating water pump and discharged to the atmosphere, the cooling water consumption of the air-conditioning unit is extremely large, and the condensed water in the evaporator of the refrigeration unit is not collected and used properly, resulting in water loss. The waste of resources and energy causes a large economic burden on enterprises and merchants.

At present, the existing central air conditioners that can recycle the condensed water simply flow back through the conduit, without a pre-cooling device when returning, the utilization rate is low, and it is not intelligent enough.
