The invention discloses an air conditioner indoor unit and an air conditioner, wherein the air conditioner indoor unit comprises an indoor fan, a first heat exchanger and a second heat exchanger which are located in the air duct of the air conditioner indoor unit, wherein the first end of the first heat exchanger communicates with an outdoor heat exchanger by a first throttle pipe, the second end of the first heat exchanger communicates with a four-way valve of an air conditioner outdoor unit; the first end of the second heat exchanger communicates with a pipeline of the air conditioner outdoor unit to receive high temperature coolant; the first heat exchanger is used for receiving cold temperature coolant in constant temperature dehumidification to evaporate for refrigeration so as to cool and dehumidify air of the first heat exchanger; and the second heat exchanger is used for receiving the high temperature coolant to condense for heating, so that the temperature of low-temperature drying air flowing through the first heat exchanger rises to room temperature by passing through the second heat exchanger. According to the technical scheme of the invention, due to the arrangement of the second heat exchanger and modification on corresponding pipelines, the purpose of constant temperature dehumidification can be achieved, energy consumption is not increased during constant temperature dehumidification, and the air conditioner is energy-saving and environment-friendly.

The invention provides an environment protective type novel technical proposal, which is suitable for integrated selection for laminar deposited and secondary deposited diaspore type and gibbsite-type bauxite ores contained high quantity of silicon, iron and sulfur. Through utilizing the novel technical proposal, during the selecting process of the alumyte, zero consumption of Na2O and Al2O3 can be achieved in desilication and the digestion of bayer process, Na2O*H2O can be used circularly without any limitation, calcium silicate, alumina, gallium compound, iron concentrate powder and calcium titanate are separated from the alumyte with a high quantity of the silicon, iron and sulfur at one time, and the high efficiency overall development and utilization for alumyte resource can be achieved, without waste ore tailings, and the level of resources utilization can be enhanced.
