Air conditioner system and control method thereof

Abstract

The invention provides an air conditioner system and a control method thereof. The air conditioner system comprises a compressor, an outdoor heat exchanger, a first indoor heat exchanger and a secondindoor heat exchanger. The air conditioner system further comprises a first branch and a second branch. One end of the first branch communicates with a first pipeline, and the other end of the first branch communicates with a second pipeline. One end of the second branch communicates with the first pipeline, and the other end of the second branch communicates with the second pipeline and is located at the position between the second indoor heat exchanger and the compressor. The first indoor heat exchanger and the second indoor heat exchanger are arranged side by side, and air airflow can sequentially flow through the first indoor heat exchanger and the second indoor heat exchanger so that heat exchange can be finished. According to the air conditioner system and the control method thereof,through the joint action of an evaporator and a reheater, the temperature of indoor air can be effectively increased under the situation that indoor air is effectively evaporated, cooled and dehumidified, the air outlet temperature of an air conditioner is not too low when dehumidification is conducted, and the situation of reduction of the indoor comfort degree is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] Existing as attached figure 1 In the conventional refrigerating and air-conditioning system shown in the figure, in order to meet the dehumidification requirement during cooling in summer, it is usually necessary to lower the temperature of the evaporator to a relatively large extent lower than the dew point temperature of the return air. [0003] From the perspective of indoor environment comfort, when the conventional air-conditioning system is used for heating in summer, especially during the rainy season in the south or when dehumidification is required, the temperature of the air outlet and the indoor temperature will be too low, causing the human body to feel uncomfortable. [0004] From the perspective of energy efficiency of the air conditioning system, under the condition of ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the air-conditioning system in the prior art is operated in the dehumidification mode in a transitional season in a hot and humid area, and the air-conditioning outlet temperature is too low to cause a decrease in comfort, thereby providing an air-conditioning system and its control method
