An energy recovery system for an air handling unit includes a support frame, an energy recovery wheel, and a wheel actuator. The support frame supports the energy recovery wheel within the air handling unit. The energy recovery wheel is configured to rotate about a rotation axis during operation. The wheel actuator is configured to drive the energy recovery wheel to rotate about the rotation axis.

An air conditioning rotating body includes a rotor having a cylindrical shape, and a labyrinth seal structure. The rotor is housed in a casing so as to be freely rotatable. The air conditioning rotating body treats air passing through the rotor in an axial direction. The labyrinth seal structure is provided between an outer circumferential portion of the rotor and the casing. The labyrinth seal structure includes a first protrusion protruding in the axial direction from the rotor toward the casing, and a second protrusion protruding in the axial direction from the casing toward the rotor.

An insulation retaining assembly for a high temperature rotary pre-heater having a cold-end rotor and a hot-end rotor includes a plurality of elongate retainer elements. Each of the retainer elements has a root end adapted to be held in fixed relationship to the cold-end rotor and a distal end proximate to the hot-end rotor. Portions of each of the plurality of retainer elements are adapted for circumferential movement.

A rotor for a high temperature rotary pre-heater includes a hub that has an exterior surface thereon. The rotor includes an annular rim positioned around and coaxially with the hub. The annular rim has an interior surface. A plurality of partitions extend between the hub and the annular rim. Each of the partitions is located in a predetermined circumferential position by one or more alignment features. The exterior surface, the interior surface and/or the partitions have one or more of the alignment features thereon.

A rotary heat exchanger through which a first fluid flowan outside air or inlet air flow, for exampleand a second fluid flowan exit air or outgoing air flow, for examplecan flow in a counterflow configuration, has a rotatably mounted rotor (5) that has a first flow sector for the first fluid flow and a second flow sector for the second fluid flow through which the rotor (5) passes during a rotation, a frame in which the rotor (5) is rotatably supported, and a sealing assembly (9) by means of which an inflow side of the first fluid flow and an outflow side of the second fluid flow can be separated from the outflow side of the first fluid flow and from an inflow side of the second fluid flow, respectively. In order to simplify the sealing assembly, with the aim being that a reliable seal between the inflow and outflow sides of the two fluid flows be automatically ensured during operation of the rotary heat exchanger, it is proposed that the sealing assembly (9) have a first seal (12) that bears sealingly against the side of a partition (10) directed upstream into the first fluid flow (2), and a second seal (13) that bears sealingly against the side of the same partition (10) directed upstream into the second fluid flow (3).

An air conditioning apparatus comprises an inlet module, an airflow guiding module, a hygroscopic wheel a dehumidification heating module and an internal recirculation heating module. The airflow guiding module includes an air channel switching unit, an outflowing air channel in air communication with an external environment outside of an air-conditioning environment, and an inflowing air channel in air communication with the air-conditioning environment. The air conditioning apparatus of the present invention meets various requirements for air conditioning. In addition, when the air conditioning apparatus performs a dehumidification process, the hygroscopic wheel and the dehumidification heating module is applied to remove the moisture of the air conditioning flow of the inflowing air channel, and thus the relative humidity of the air-conditioning environment is directly reduced so as to increase the dehumidifying efficiency.
