Abstract

The invention discloses a heat exchanger subassembly intended for indoor unit of the air conditioner. The indoor unit has an air duct, and the heat exchanger subassembly is fitted in the air duct and comprises the first heat exchanger, the secondary heat exchanger and an electronic expansion valve. The secondary heat exchanger is located at the upper hand of at least part of the first heat exchanger. The first electronic expansion valve is connected to the refrigerant flow path of the first heat exchanger and the refrigerant flow path of the secondary heat exchanger in series. The present invention also discloses indoor unit and air conditioner. In the above-mentioned heat exchanger, when the air conditioner is required to implement heating and dehumidifying simultaneously, the refrigerant flow path of the air conditioner is adjusted such that the refrigerant absorbs the heat from the air when the indoor air passes through the second heat exchanger, the water vapor in the air is condensed into the liquid state and is separated from the air so as to achieve the purpose of dehumidifying, the dehumidified air absorbs the heat released by the refrigerant when it passes through the first heat exchanger, and the air temperature rises to fulfill the heating purpose; therefore, the air conditioner can implement heating and dehumidifying simultaneously.

Description

technical field [0001] The invention relates to the technical field of air conditioners, more specifically, to a heat exchanger assembly, an indoor unit and an air conditioner. Background technique [0002] The current air conditioner uses the heat exchanger of the indoor unit to absorb heat and condense the moisture in the air to achieve the effect of dehumidification. However, for cold and humid weather, users often hope that the air conditioner can both heat and dehumidify, and the existing air conditioners cannot meet the requirements. Contents of the invention [0003] The embodiments of the present invention aim to solve at least one of the technical problems in the prior art. Therefore, the embodiments of the present invention need to provide a heat exchanger assembly, an indoor unit and an air conditioner. [0004] The heat exchanger assembly according to the embodiment of the present invention is used for an indoor unit of an air conditioner. Heat exchanger and...
