A housing for a component (e.g., a heat exchanger) of a heating, ventilation, and/or air conditioning (HVAC) system is disclosed that includes one or more attachment flanges and/or one or more support flanges that are integrated into the housing. The disclosed housing reduces or completely eliminates the use of separate brackets and fasteners when installing components within the housing and/or when coupling the housing to other components of the HVAC system. By dramatically reducing or eliminating these separate components, the disclosed housing designs reduce the likelihood for installation errors, as well as delays due to misplaced brackets and/or fasteners during installation. Accordingly, the disclosed housing designs enable a cost-effective solution for reducing the cost and complexity of installing HVAC system components.

An air-sending device includes a housing including an inlet air passage communicating with an air inlet and an outlet air passage communicating with an air outlet, a first partition plate partitioning an interior of the housing into the inlet air passage and the outlet air passage, a bell mouth disposed around an opening defined in the first partition plate, and an impeller disposed over the first partition plate across the bell mouth and having a rotation axis that extends in a direction that intersects the first partition plate. The impeller suctions air into the inlet air passage from the air inlet, and blows out air from the air outlet through the outlet air passage. The inlet air passage guides air from the air inlet to the opening along the first partition plate, and has an air-passage wall.

An air conditioner includes a casing, and a blower and a refrigerant circuit disposed in the casing. The blower is configured to blow air. The refrigerant circuit has a compressor, a condenser, a decompressor, and an evaporator and is configured to circulate refrigerant in order of the compressor, the condenser, the decompressor, and the evaporator. The condenser has a first heat transfer tube through which the refrigerant flows and which has a first outside diameter. The evaporator has a second heat transfer tube through which the refrigerant flows and which has a second outside diameter. The evaporator is disposed windward of the condenser. The first outside diameter of the first heat transfer tube of the condenser is smaller than the second outside diameter of the second heat transfer tube of the evaporator.

An air-conditioning system having a discharge device (10) for discharging condensed water from the air-conditioning system, wherein the discharge device has a piping system (2) for guiding the condensed water, wherein the discharge device has a regulating element (3) and the regulating element is configured as an open channel rotatable about a longitudinal axis (4) between a first rotational position and a second rotational position. The regulating element (3) is configured and arranged such that the regulating element guides the condensed water inside the piping system (2) in the first rotational position and establishes a continuous connection between a drip-off point for the condensed water and an outer area around the air-conditioning system in the second rotational position.

The present invention relates to an air-conditioning device comprising: a case having an interior divided into a first area and a second area, having an indoor inlet and an indoor outlet formed therein such that the first area and an indoor space communicate with each other, and having an outdoor inlet and an outdoor outlet formed therein such that the second area and an outdoor space communicate with each other; a barrier arranged between the first area and the second area inside the case; an indoor blowing fan arranged in the first area so as to form a flow of air from the indoor inlet to the indoor outlet; an outdoor blowing fan arranged in the second area so as to form a flow of air from the outdoor inlet to the outdoor outlet; a first thermoelectric element comprising a first indoor heat exchanger arranged in the first area so as to exchange heat with air passing through the first area, and a first outdoor heat exchanger arranged in the second area so as to exchange heat with air passing through the second area; a case lower-surface formed on the lower surface of the case so as to have an open upper side such that condensed water generated from the first thermoelectric element is collected; and a second thermoelectric element arranged between the first thermoelectric element and the case lower-surface so as to heat the condensed water. The first area and the second area are connected between the case lower-surface and the second thermoelectric element such that the condensed water is distributed across the first area and the second area. The present invention is advantageous in that indoor cooling/heating can be performed without no separate compressor, outdoor unit, and the like, and condensed water can be effectively evaporated.

An air conditioner includes a housing having a first outlet and a second outlet, a first channel communicating with the first outlet, a second channel communicating with the second outlet, a tank unit configured to hold water for cooling first air and second air, the first air flowing through the first channel, the second air flowing through the second channel, a cooling unit configured to cool the first air by heat of vaporization of water held in the tank unit, a water supply channel for supplying water held in the tank unit to the cooling unit, and a water recovery channel for collecting water remaining in the cooling unit to the tank unit.

An air conditioner including a heat exchanger; a blower fan; a compressor; and a controller. The controller performs: a cooling process in which the compressor is operated to compress a circulating refrigerant, the heat exchanger performs heat exchange between the refrigerant and air, and the blowing fan is operated to blow air to the heat exchanger. The controller performs a drying process including: performing, a blowing process in which the blower fan is operated to blow air to the heat exchanger while the compressor is stopped, and performing a heating process in which the refrigerant is circulated in a direction that is changed from that of the cooling process, the blower fan is operated to blow air to the heat exchanger, and the compressor is operated to compress the refrigerant, thereby heating the surface of the heat exchanger and drying water condensed on the surface of the heat exchanger.

A method for anti-condensation at an air conditioner radiation terminal in the present invention belongs to the field of air conditioning devices. When a dehumidifying heat exchanger in a fresh air ventilator performs refrigeration to dehumidify, heat of condensation generated in the dehumidification in the fresh air ventilator is used for providing a heat source for the indoor radiation terminals, thereby preventing condensation and reducing consumption of electric energy.
