Problems solved by technology
[0003] On the one hand, the condensed water of the conventional centralized central air-conditioning system is directly discharged, and the condensed water contains a large amount of cold energy, which cannot be recycled and reused.
On the other hand, the fresh air system directly introduces outdoor air, and the temperature of the outdoor air conditioner is high. The fresh air unit of the central air conditioner needs to consume a large part of the cooling capacity to cool down the introduced outdoor air to reach the supply air temperature of the indoor air conditioner, which will cause big waste of energy

Description
technical field [0001] The invention belongs to the technical field of centralized central air-conditioning engineering, and relates to an energy-saving device, in particular to an energy-saving device capable of reducing the heat load of air-conditioning fresh air in summer. Background technique [0002] Centralized central air-conditioning systems are used to heat and cool buildings. The requirements for sealing inside buildings are getting higher and higher to achieve the energy-saving operation of central air-conditioning. After the buildings are sealed, the requirements for fresh air are also getting higher and higher. The energy consumption of fresh air accounts for The proportion of the entire central air conditioner is also increasing, reducing the energy consumption of fresh air has become a hot spot in building energy conservation at home and abroad in recent years. [0003] On the one hand, the condensed water of the conventional centralized central air-conditioni...
