Disclosed are a variable capacity compressor operation mode determination method and device, a variable capacity compressor and an air conditioner. The variable capacity compressor operation mode determination method includes: detecting a current value of a compressor at present as A1 before switching an operation mode of the compressor; detecting the current value of the compressor at present as A2 after switching the operation mode of the compressor and reaching a preset time; comparing A1 and A2, determining that the switching of the operation mode of the compressor is successful when a ratio relationship between A1 and A2 satisfies a preset condition, and determining that switching of the operation mode of the compressor is failed when the ratio relationship between A1 and A2 dissatisfies a preset condition.

The present disclosure relates to an air-conditioning outdoor device and an air conditioner unit. The air-conditioning outdoor device comprises: an outdoor unit housing; a primary air return port and an air outlet port provided on a front panel on a side of the outdoor unit housing away from an installation wall; and a supplementary air return port provided on a side panel of the outdoor unit housing adjacent to the front panel; wherein the primary air return port and the supplementary air return port both communicate with an air return chamber inside the outdoor unit housing. The air-conditioning outdoor device of the present disclosure can effectively increase the air flow volume through the air port of the air-conditioning outdoor device.

Air-conditioning outdoor device and air conditioner unit

Provided are a method and device for controlling electric heating of an air conditioner compressor. The method may include: first request information is transmitted to a corresponding database server at an interval of a second preset duration, as to acquire weather forecast data of an area where an air conditioner is located within an upcoming third preset duration; the weather forecast data returned by the database server is received and stored in a built-in database of the air conditioner; it is monitored to learn that a shutdown duration of the air conditioner compressor exceeds a first preset duration, as to acquire the weather forecast data stored in the built-in database of the air conditioner; and a control strategy is generated according to the weather forecast data, to control the air conditioner compressor to start and stop electric heating.

The present disclosure relates to an embedded type air conditioner outdoor unit and an air conditioner. The embedded type air conditioner outdoor unit comprises: a housing comprising an air inlet and an air outlet which are provided on the same side surface of the housing; a heat exchanger provided within the housing, for heat exchange with air introduced by the air inlet; and a cross-flow fan provided within the housing, for flowing the air introduced by the air inlet through the heat exchanger. By applying the technical solution of the present application, the air introduced by the air inlet after heat exchange by the heat exchanger is expelled via an exhaust port by using the cross-flow fan, thereby improving the problem of much noise of the embedded type air conditioner outdoor unit.

The present disclosure relates to an embedded type air conditioner outdoor unit and an air conditioner, wherein the embedded type air conditioner outdoor unit is configured to be embedded within a wall of a building, and the embedded type air conditioner outdoor unit comprises a heat exchanger, which includes a first inlet for introducing a refrigerant and a second inlet for introducing a heat exchange medium to perform heat exchange with the refrigerant. By applying the technical solution of the present application, in which the heat exchange medium is used to perform heat exchange with the refrigerant, the embedded type air conditioner outdoor unit of the present embodiment may be used without a fan system, so that the embedded type air conditioner outdoor unit has reduced vibration and noise.

An air-conditioner outdoor device and an air-conditioner unit are provided. The air-conditioner outdoor device includes a casing and a heat exchanger, wherein the heat exchanger is disposed within the casing, a front plate of the casing is provided with an air outlet and two air inlets, the air outlet is located between the two air inlets, the heat exchanger is positioned closer to the front plate relative to a rear plate of the casing and faces the air outlet, and air flow entering the casing from the air inlets flows out of the casing from the air outlet after flowing through the heat exchanger. The air-conditioner unit comprises the air-conditioner outdoor device. The air-conditioner outdoor device of the present application improves the air intake and outlet manners to facilitate the installation of the air-conditioner outdoor device in a mounting hole through a wall and indoors.
