A housing assembly includes a panel having a plurality of sub-panels including a first sub-panel and at least one second sub-panel, the first sub-panel being fitted with an electric control box of an air-conditioner outdoor for shielding the electric control box. According to the housing assembly provided in the present disclosure, when an electric control box is to be maintained, only the first sub-panel is removed to expose the electric control box, without removing two panels to expose the electric control box, thereby reducing the difficulty of electric control maintenance and improving the convenience of electric control maintenance.

An outdoor unit includes at least one heat exchanger, a first motor including a first fan, a second motor including a second fan, an inverter that applies voltage to the first motor and the second for respectively, a connection switching unit that switches the voltage applied to the second motor between on and off, and a control unit that controls the inverter and the connection switching unit. The inverter is disposed closer to the first motor than to the second motor.

Disclosed is an air conditioner including a first frame including a through hole, a second frame rotatably coupleable to the first frame, the second frame including a burring portion at least a portion of which is insertable into the through-hole in a first direction, where while the burring portion is inserted into the through-hole of the first frame, the burring portion protrudes in the first direction, and a burring hole formed by the burring portion, and a fastening member insertable into the burring hole in a second direction opposite to the first direction and configured to function as a rotary shaft of the second frame, where while the fastening member is inserted into the burring hole, the fastening member protrudes in the second direction.

A heating, ventilation, and/or air conditioning (HVAC) unit includes a housing having a base wall, a first electrical component coupled to the base wall, a panel movably coupled to the housing and configured to transition between a closed configuration that defines an air gap between the panel and the base wall and that blocks access to the first electrical component and an open configuration that enables access to the first electrical component, and a second electrical component coupled to the panel. The second electrical component is disposed on a side of the panel opposite the air gap in the closed configuration of the panel.

A near field communication device for a heat, ventilation, and air conditioning (HVAC) system including: a near field radio antenna configured to detect and transmit near field communication wireless signals, wherein the near field radio antenna is configured to be attached to a housing of an outdoor unit of the HVAC system; a near field transceiver configured to communicate with a mobile device through the near field radio antenna; and a controller configured to be in electronic communication with an outdoor controller of the outdoor unit.

A mobile air conditioner includes a housing, an electric control box mounted at the housing, and a wire control assembly mounted at the housing. The wire control assembly includes an adapter mounted at the housing and connected to the electric control box, and a wire controller connected to the adapter.

An outdoor unit includes a housing including a side panel, a terminal block accommodated in the housing, and a power supply wire connected to the terminal block. The side panel includes an outer shell surface forming a part of an outer surface of the housing, a first recessed surface recessed from the outer shell surface in an inward direction of the housing, and a second recessed surface formed in the first recessed surface and recessed from the first recessed surface in the inward direction of the housing. The power supply wire is arranged on the second recessed surface.

The power supply wire is arranged on the second recessed surface.

The electric control box includes a box body, a mounting plate, a heat sink, an electronic component and a heat dissipation fan. The box body is provided with a mounting cavity. The mounting board is arranged in the mounting cavity to form a first chamber and a second chamber located on two sides of the mounting board. A first air vent and a second air vent are arranged on the mounting board and are spaced apart. The first air vent and the second air vent are connected to the first chamber and the second chamber. The heat sink is at least partially arranged in the first chamber. The electronic component is arranged in the second chamber and in thermally conductive connection with the heat sink. The heat dissipation fan is used for blowing air and from the first chamber into the second chamber via the first air vent.
