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.

Dynamic oil fume purification device, which includes a box body, an exhaust and a gas collection device, the box body has an air inlet and an air outlet, and a centrifugal purification disc is installed in the air duct of the box body, and the purification disc is installed on the motor shaft in the box body. The body is provided with an oil receiving mechanism, and the feature is that: the purification disc includes a mesh disk and a disk shaft sleeve, and the mesh disk and the disk shaft sleeve are fixedly connected or integrated, and the mesh disk is a circular plate-shaped object, and the plate-shaped object There are through grooves along the radial direction of the network disk, and spokes are formed between the two through grooves, and a plurality of spokes are distributed sequentially on the circumferential surface of the plate. The utility model has the advantages of simple structure, high oil filtration rate, long service life and high manufacturing efficiency, and is an environment-friendly and high-efficiency oil fume purification device which can be used in the catering industry and in the family kitchen.

The invention relates to a movement trend hybrid positioning method, comprising the following steps: a mobile device calculates base station related information and WIFI hotspot information through data acquisition and operation; the mobile device transmits base station data to a server, the server performs signal difference calculation to obtain longitude and latitude of the mobile device; when the mobile device contains a GSM module, the server performs differential position calculation for differential signal values of multiple base station signals; when the mobile device is in a moving state, the server performs movement trend analysis on the data transmitted by the base station to obtain longitude and latitude of the mobile device; when the mobile device has no communication signal and no GPS signal, the server adopts WIFI signal differential positioning; and when the mobile device simultaneously has a GPS communication module and a WIFI communication module, the server automatically adopts an energy consumption algorithm. The method provided by the invention effectively solves a problem of precision of positioning in different geographical environment and different hardware environment, effectively promotes battery endurance of the device and greatly reduces cost of hardware products.
