A dehumidifier includes a machine body including a case. The case includes an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet. The dehumidifier further includes an axial flow fan arranged in the air duct. An air outlet direction of the axial flow fan is configured to face the air outlet. The dehumidifier also includes a compressor arranged inside the case and side by side with the axial flow fan.

A vaneaxial blower system having a stator and a rotor is disclosed. Each of the stator and rotor have a hub and blades, each of the blades have a leading edge and a trailing edge, an angle theta defined by a line extending from the respective leading edges to the respective trailing edges and the respective hub and an angle beta defined as an angle measured between a camber line between a first blade and a second blade and a horizontal tangential line that extends through respective leading edges of the first and second blade.

An air conditioner including a housing; a heat exchanger in the housing; an outlet; a blower to discharge air forward toward the outlet, the air having exchanged heat with the heat exchanger; and a guide panel in front of the blower, and including an inner panel coupled with the outer panel, and a suck-in flow path formed by the inner panel and the outer panel, wherein the guide panel forms the outlet with the housing to release a first portion of the air discharged by the blower outside of the housing, and the suck-in flow path sucks in a second portion of the air discharged by the blower so as to guide the first portion of the air to flow outside of the housing in a direction different than when the second portion of the air is not sucked into the suck-in flow path.

Architectures and techniques are presented that can facilitate improved design and function of certain air handler devices. Architectures directed to an improved air handler device can be designed to improve temperature control demands such as, e.g., concurrently heat and cool air and reducing device dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties.

Disclosed herein is an air conditioner comprising, a housing in which an outlet is formed, a heat exchanger positioned inside the housing, and a fan positioned behind the heat exchanger. The fan configured to blow air to the heat exchanger. And a filter assembly coupled to the housing. The filter assembly configured to filter air entering the fan. The filter assembly covering a rear portion of the fan.

Disclosed herein is an air conditioner including a main outlet and a plurality of fine outlets provided in a main body, wherein at least one discharge guide for guiding air discharged by a blowing fan to one of the main outlet and the fine outlets is disposed in the inside of the main body to cool indoor space in various ways.

Disclosed is an air conditioner. The disclosed air conditioner comprises: a main discharge port formed in a housing so as to discharge air introduced through a first inlet; a first guide discharge port configured to discharge a portion of air introduced through a second inlet such that the portion of the air introduced through the second inlet is mixed with the air discharged from the main discharge port; a second guide discharge port configured to discharge another portion of the air introduced through the second inlet such that the another portion of the air introduced through the second inlet is mixed with the air discharged from the main discharge port; and a distribution device configured to adjust the flow rate of the air discharged through the first guide discharge port and the second guide discharge port.

Architectures and techniques are presented that can facilitate improved design and function of certain heating, ventilation, and air conditioning (HVAC) devices. Architectures directed to an improved evase device can be designed with rounded corners that can facilitate, e.g., mitigation of reverse flow that traditionally grows back from corners of a transition from an axial fan to a rectangular duct. Architectures directed to an improved intake device can be designed to limit intake from certain flow directions and to smoothly change flow direction, which can facilitate, e.g., reduction in noise. Architectures directed to an improved fan intake device can be designed to reduce noise without significantly reducing total pressure. Architectures directed to an improved air handler device can be designed to concurrently heat and cool air and to reduce dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties.
