An environmental control unit for providing heated or cooled air to an enclosed environment, such as a building structure or temporary shelter. Air passes through the environmental control unit and the air is heated or cooled by a temperature control system of the environmental control unit. The heated or cooled air is provided to the enclosed environment.

The present disclosure provides a heating-type humidifier, including a water tank and a base. The water tank is arranged within the base, and the water tank includes a gas guide pipe, a gas outlet, and a water filling port; the gas outlet is communicated with the gas guide pipe. The base defines a cold gas tank and a heating tank that are communicated with the gas guide pipe, and the cold gas tank is communicated with the water tank through a water supply switch. The cold gas tank is communicated with the heating tank through a guide pipe, the guide pipe being a heat dissipation pipe.

An air-conditioning apparatus includes: a housing having an intake air passage communicating with an air inlet and a blowout air passage communicating with an air outlet that allows air to be blown out in a single direction; a fan; a front heat exchanger facing the air outlet of the housing and including first and second heat exchangers; and at least one of rear and side heat exchangers that face rear and side surfaces of the housing, respectively. When the front heat exchanger operates as a condenser, the first heat exchanger operates as a condenser, and condensed and liquified refrigerant flows in the second heat exchanger. The second heat exchanger is located downstream of the first heat exchanger and the at least one of the rear and side heat exchangers in the flow direction of a refrigerant.

A fresh air module and an air conditioner are provided. The fresh air module has a housing and a fan assembly. The housing has a fresh air duct inside the housing. The fan assembly has a motor and a wind wheel disposed in the fresh air duct. The motor has a motor body and a motor shaft. The motor shaft drives the wind wheel to rotate, so as to guide airflow to flow through the fresh air duct. The motor cover is arranged on the housing and outside of the fresh air duct. A motor accommodating cavity is defined in the motor cover and accommodates the motor body. A partition member is formed between the motor accommodating cavity and the fresh air duct to separate the motor accommodating cavity from the fresh air duct. The motor shaft penetrates through the partition to connect with the wind wheel.

Disclosed are a fresh air module and an air conditioner. The fresh air module has a housing, a fan assembly and a purification assembly. The housing is provided with a fresh air inlet and a fresh air outlet. A fresh air duct is formed in the housing and communicates the fresh air inlet with the fresh air outlet. The fan assembly is mounted in the fresh air duct. The purification assembly is disposed in the fresh air duct and located at one end of the fan assembly in an axial direction of the fan assembly to correspond to an air inlet end of the fan assembly.

Disclosed is a window air conditioner having a constant temperature dehumidification mode. A first indoor heat exchanger and a second indoor heat exchanger of the air conditioner are stacked in an air inlet direction of an indoor air duct of the air conditioner. In the constant temperature dehumidification mode, one of the indoor heat exchangers is configured to be in a heating mode, and the other one is configured to be in a cooling mode. In this way, both fresh air and indoor air may be dehumidified and heated, a user may feel the fresh air and the temperature of the dehumidified air is comfortable.

A fresh air module and an air conditioner are provided. The fresh air module has a housing, a middle partition plate and a fan assembly. The housing is provided with a fresh air duct, which has an air inlet cavity and an air outlet cavity. The middle partition plate is arranged in the fresh air duct, located between the air inlet cavity and the air outlet cavity, and is provided with a ventilation hole that communicates the air inlet cavity and the air outlet cavity. The fan assembly is installed in the air outlet cavity.

The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.

Disclose are a wall-mounted air conditioning indoor unit and an air conditioner. The wall-mounted air conditioning indoor unit includes: an indoor unit body; a fresh air module including a housing, the housing being provided with a fresh air inlet, a fresh air outlet, and a fresh air duct communicating the fresh air inlet with the fresh air outlet, the fresh air inlet being configured to communicated with the outdoor environment, and the fresh air outlet being communicated with an air inlet of the indoor unit body; a wind wheel installed in the fresh air duct; and a valve installed at the fresh air inlet to open or close the fresh air inlet.

A heat exchange unit includes a housing having an inflow air passage communicating with an air inlet, and an outflow air passage communicating with an air outlet, a first partition plate that partitions an inside of the housing into the inflow air passage and the outflow air passage, a bellmouth disposed around an opening formed in the first partition plate, a centrifugal fan disposed on the first partition plate via the bellmouth, and a heat exchanger disposed on a downstream side of the centrifugal fan in the housing. The air inlet is open at any surface of the housing having the inflow air passage. The air outlet is open at any side surface of the housing having the outflow air passage. The inflow air passage is formed between a fan inlet and a main plate closest to the fan inlet to reach a rear surface. The fan inlet is an air inlet of the centrifugal fan.
