摘要:
Disclosed are a dehumidification apparatus, and an air conditioning apparatus and system having the same. The dehumidification apparatus includes: a desiccant rotor having a desiccant for adsorbing moisture; and a regeneration unit disposed at one side of the desiccant rotor, for desorbing the moisture adsorbed to the desiccant. The regeneration unit includes at least one of a hollow hot water line containing hot water exchanging heat with the air flowing toward the desiccant rotor. The dehumidification apparatus efficiently reproduces the desiccant for dehumidification and air conditioning.
摘要:
A dehumidification rotor traps water in air to dehumidify the air. The water trapped by the dehumidification rotor is collected in a water tank. The water to be collected in the water tank is purified by a water purification unit. A humidification rotor imparts the purified water to air to humidify the air.

A method and apparatus for conditioning ambient air for use in an enclosure is disclosed which cools the ambient supply air stream in sensible energy recovery device or cools and dehumidifies the ambient supply air stream in an enthalpy energy recovery device. The thus cooled air is then cooled by a cooling coil of a refrigerant cooling system to reduce its temperature and humidity. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel or through a different type of desiccant dehumidification device under conditions which reduce its moisture content and increases its temperature. The supply air is then delivered from the desiccant wheel to the enclosure. The desiccant wheel is regenerated by heating a separate regeneration air stream, provided by the exhaust air from the space and using the condensing coil of the refrigerant system to increase the regeneration air stream temperature. The thus heated regeneration air stream is then passed through another segment of the rotating desiccant wheel to regenerate the wheel and is exhausted to the atmosphere.

摘要:
The object of the invention is an air supply unit (1) for recovering heat energy from an air stream (e.g., exhaust air) and transferring the heat energy to another air stream (e.g., supply air). The air supply unit (1) comprises a casing (25), in the casing (25) an exhaust air channel (4) for leading exhaust air (2) through the casing (25) of the air supply unit (1), in the casing (25) a supply air channel (7) for leading supply air (7) through the casing (25) of the air supply unit (1), and in the casing (25) a heat exchanger (10) for transferring heat energy between the exhaust air (2) flowing in the exhaust air channel (4) that leads through the casing (25) and the supply air (3) flowing in the supply air channel (7). In the casing (25), the air supply unit (1) comprises a heat pump (11) having a first heat interchanger (12) having a first interior for refrigerant, and a second heat interchanger (13) having a second interior for refrigerant. The first heat interchanger (12) is adapted into the supply air channel (4) between the first inlet (5) and the heat exchanger and the second heat interchanger (13) is adapted into the supply air channel (7).
摘要:
A humidity controller apparatus (20) contains an adsorption rotor (24) and a heater (25). A first passage (21) along which a first air stream flows and a second passage (22) along which a second air stream flows are formed in the humidity controller apparatus (20). The amount of heat exchange between the first and second air streams and the amount of moisture exchange between the first and second air streams vary by adjustment to the rotating speed of the adsorption rotor (24), and the humidity controller apparatus (20) is switched between a dehumidification operation and a humidification/heating operation. During the dehumidification operation, the rotating speed of the adsorption rotor (24) is set low. The first air stream is dehumidified by the adsorption rotor (24) and then supplied to the inside of a room. The second air stream is used for regeneration of the adsorption rotor (24) and then discharged to the outside of the room. During the humidification/heating operation, the rotating speed of the adsorption rotor (24) is set high. The first air stream receives heat and moisture from the adsorption rotor (24) and then is supplied to the inside of the room. The second air stream is heat/moisture-adsorbed by the adsorption rotor (24) and then discharged to the outside of the room.
摘要:
An HVAC system includes a desiccant wheel, wherein the wheel's speed varies with airflow, the wheel is energized for at least a set period at startup, and/or a heat recovery system (e.g., an air-to-air heat exchanger) upstream of the wheel enhances the system's ability to dehumidify air.
摘要:
A humidity control system during humidification operation sequentially repeats a first mode in which a second adsorption heat exchanger (82) serves as an evaporator and the remaining adsorption heat exchangers serve as evaporators, a second mode in which a third adsorption heat exchanger (83) serves as an evaporator and the remaining adsorption heat exchangers serve as evaporators and a third mode in which a first adsorption heat exchanger (81) serves as an evaporator and the remaining adsorption heat exchangers serve as evaporators. For example, during the first mode, the first adsorption heat exchanger (81) serving as an evaporator adsorbs moisture in a first air. Furthermore, in the second adsorption heat exchanger (82) serving as a condenser, the adsorbent is regenerated to humidify a second air. Furthermore, in the third adsorption heat exchanger (83) serving as an evaporator, the second air given moisture and heat in the second adsorption heat exchanger (82) is cooled. The humidity control system supplies the second air humidified by the second adsorption heat exchanger (82) and cooled by the third adsorption heat exchanger (83) to a room.
