Abstract

The invention discloses a heat exchanger, an air-conditioning indoor unit and an air conditioner. The heat exchanger comprises a first port, a second port and at least two heat exchanging areas arranged in parallel between the first port and the second port, and a first valve is arranged between at least one heat exchanging area and the first port and / or the second port; and the heat exchanger further comprises a distributing pipe and a second valve arranged on the distributing pipe, and the distributing pipe communicates with the two heat exchanging areas. According to the heat exchanger, theheat exchange energy efficiency of refrigerating and heating can be improved synchronously, and thus the ability energy efficiency of the air-conditioning indoor unit and the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchanger, an air conditioner indoor unit and an air conditioner using the heat exchanger. Background technique [0002] The energy saving of air conditioners has attracted more and more attention. In order to improve the energy efficiency and efficiency of air conditioners, the method of increasing the heat exchange area of ​​heat exchangers is generally adopted, which increases the overall cost of air conditioners. At present, when the heat exchanger used in an air conditioner meets the energy efficiency requirements of cooling or heating, it usually sacrifices the energy efficiency of the heat exchanger in another operating mode. The energy efficiency of the heat exchanger is low, and it is difficult to simultaneously Taking into account the heat exchange efficiency of cooling / heating. [0003] The above is only used to assist the understanding of the technica...
