Energy-saving air conditioning fresh air device for recycling condensed water of air conditioner

Abstract

The invention provides an energy-saving air conditioning fresh air device for recycling condensed water of an air conditioner. The device comprises a fresh air coil box, a condensed water box, a circulating water pump, a plurality of valves and a plurality of sections of connecting pipelines. The device is further provided with a condensed water box water temperature and water level control system, and the condensed water box water temperature and water level control system is used for controlling the water box temperature and the water level, ensuring that the water temperature of the water box is lower than a set value and the water level is higher than a set value, and meeting requirements for condensed water circulation and fresh air treatment. The problem about effective recycling ofthe condensed water of the air conditioner is solved, and the device can be used in both winter and summer; and the energy consumption for treating fresh air can be expected to be reduced by 20-40% for an air conditioner system where fresh air is directly introduced, and good economic benefits and social benefits can be achieved. Adverse effects of direct introduction of the fresh air on normal operation of the air conditioner system can be reduced, and the comfort level of the air conditioner is improved.

Description

technical field [0001] The invention relates to heat recovery air-conditioning technology, in particular to an air-conditioning condensed water recovery and energy-saving air-conditioning fresh air device. Background technique [0002] For places that do not require high air-conditioning comfort but need to introduce fresh air, the fresh air method is usually used to send the fresh air into the room after being processed by an ordinary air conditioner. This fresh air method is simple and the fresh air volume is guaranteed, but the comfort of the air conditioner is average. Because the air conditioner unit is of ordinary type, it is designed under the indoor return air condition instead of the fresh air condition, so its processing enthalpy difference is small, and the fresh air processing capacity is limited. If the fresh air ratio is too high (greater than 15%), it will cause indoor The air supply temperature cannot meet the design requirements, and it is not conducive to t...

AI Technical Summary

Problems solved by technology

During the cooling process of the air-conditioning system in summer, the surface cooler of the air-conditioning unit will produce a large amount of condensed water, and these condensed waters tend to be lower in temperature and have less impurities. Therefore, this part of condensed water has relatively high utilization value, but for a long time This part of the condensed water is directly discharged into the sewage pipe and is wasted in vain.
