The invention discloses a wall-mounted air conditioner including an indoor unit. The indoor unit includes a front housing and a rear housing forming housing, the housing is provided with main air intake portions, heat exchangers are disposed inside the housing, both orthographic projection of the front housing and the rear housing are circular or approximately circular, the rear housing is located within a limiting area of the front housing, a surface of the front housing is an arc surface in which an upper portion and a lower portion contract backwards and a middle portion protrudes forwards, and a lower portion of the front housing is provided with an air outlet. The wall-mounted air conditioner according to the invention improves a structure of an existing wall-mounted air conditioner and can output air backwards, thereby ensuring fast flow and temperature adjustment of indoor air.

An HVAC system includes a front side access panel, an HVAC unit, a mounting sleeve, and a back side grille. The mounting sleeve and the HVAC unit are configured to fit within the preexisting framing of a building, and in particular to be mounted in a wall, between pre-existing studs, of a room. The HVAC unit includes an evaporator section, a mechanical section, and a condenser section. The HVAC system is optimized to maximize space utilization and support efficient installation and servicing while minimizing product intrusion into living space. The evaporator section includes a heat exchanger, an air mover, and electrical circuitry. The air mover and the heat exchanger can have a variety of different configurations, all designed for implementation within the limited confines between preexisting studs of the wall. The heat exchanger can include a coil assembly having an evaporator coil and a plurality of fins.
