AI Technical Summary

Technical Problem

Current air conditioning products generally only use a single refrigeration technology and fail to effectively combine refrigerant refrigeration and adsorption refrigeration technologies to improve performance.

Method used

A dual-cooling air conditioner was designed, which combines a refrigerant heat exchange system and two adsorption refrigeration systems. The alternating operation of refrigerant and adsorption medium is achieved by switching the pipeline on and off, optimizing the refrigerant flow path of the indoor and outdoor heat exchangers, and realizing the combination of refrigerant and adsorption refrigeration.

Benefits of technology

It improves the cooling effect of the air conditioner, reduces the power consumption of the refrigerant heat exchange system, simplifies the air conditioner structure, and enhances the overall cooling performance.

Abstract

This application relates to the field of air conditioning and refrigeration technology, and discloses a dual-cooling air conditioner. The dual-cooling air conditioner includes: a refrigerant heat exchange system and two adsorption refrigeration systems; wherein, the refrigerant heat exchange system includes two indoor heat exchangers and two outdoor heat exchangers, each indoor heat exchanger is provided with an indoor parallel pipeline, and each outdoor heat exchanger is provided with an outdoor parallel pipeline; each adsorption refrigeration system includes an evaporator section disposed at an indoor heat exchanger and an adsorption section disposed at an outdoor heat exchanger, with an adsorption medium transport path constructed between the evaporator section and the adsorption section. The air conditioner provided in this disclosure can utilize the heat dissipated by the two outdoor heat exchangers to drive the adsorption refrigeration system to perform desorption and cold storage, and can utilize the stored cold energy to continue cooling the indoor side.
