The invention discloses a cabinet-type indoor unit and an air conditioner. The cabinet-type indoor unit comprises a shell, a cross-flow wind wheel and a single-row heat exchanger. A wind inlet is formed in the rear side wall of the shell, and a wind outlet is formed in the front side wall of the shell. The wind outlet extends in the up-down direction, and a wind passage communicating the wind inlet with the wind outlet is formed in the shell, and the cross-flow wind wheel is mounted in the wind passage and arranged in an up-down extending mode. The single-row heat exchanger is arranged in thewind passage and located between the cross-flow wind wheel and the wind inlet. The single-row heat exchanger comprises a fin set and a coil set arranged on the fin set. The coil set comprises a plurality of primary coils and a plurality of secondary coils, wherein the primary coils and the secondary coils are sequentially arranged from bottom to top. Each primary coil is connected with at least one of the secondary coils in series to form a plurality of flow-dividing pipelines on the fin set. According to the cabinet-type indoor unit, under the heating mode, refrigerants flow from the lower ends of the flow-dividing pipelines to the upper ends of the flow-dividing pipelines.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cabinet-type indoor unit and an air conditioner. Background technique [0002] The heat exchangers usually used in conventional cabinet-type indoor units are double-row heat exchangers. The double-row heat exchangers include front row heat exchangers and rear row heat exchangers. The exhaust heat exchanger performs heat exchange, and after the heat exchange, an outlet air flow is formed to be blown indoors. Please refer to the attached Figure 1-A , when the conventional cabinet-type indoor 100' is in the heating state, the refrigerant first flows from the bottom to the top of the rear heat exchanger, and then flows out from the top to the bottom through the front heat exchanger, which is very easy to flow in the double-row heat exchanger Refrigerant liquid accumulation occurs at the lower end of the Due to the low temperature of the refrigerant liquid accumulation, ...
