An air-conditioning device includes a plurality of duct modules and a power module. The duct modules each have a temperature-adjusting unit, an air flow-guiding unit and an energy transmission module. The temperature-adjusting unit is disposed at the second end of the duct module, and has opposing first and second side surfaces. The air flow-guiding unit is disposed at the duct module. The energy transmission module is disposed between the temperature-adjusting unit and the air flow-guiding unit. The power module provides operational power for the duct modules. The air flow-guiding unit guides air flow to enter from the first end of the duct modules. The energy transmission strength of the air flow is enhanced from the energy transmission module. The air flow passes through the first or second side surface of the temperature-adjusting unit, and exists from the second end of the duct modules.

Indoor air is purified using a purifying solution in an arrangement capable of removing formaldehyde and other pollutants, such as, for example, particulates. The arrangement can prevent re-vaporization of volatile compounds and can generate air that has been humidified or dehumidified. In one approach, incoming air is contacted with the purifying solution in a packed bed.

An air conditioning device includes a duct module and a heat exchange module. The duct module includes a temperature control unit disposed at a second region of the duct module, a first air flow guide unit disposed between a first region and the second region of the duct module, and a first liquid energy conducting element disposed at the first region of the duct module. The heat exchange module has a delivery duct, an accommodating case, a driver unit, a second air flow guide unit, a heat exchanger and a second liquid energy conducting element. The driver unit drives condensed water to pass through the delivery duct. The second air flow guide unit provides an air flow to the heat exchanger for exhausting waste heat. The second liquid energy conducting element performs heat exchange to cool down.

An air-conditioning device is provided, having a plurality of duct modules and a power module. Each of duct modules has a first end, a second end opposite to the first end, a temperature adjusting unit, and a first airflow guiding unit. The temperature adjusting unit has a first side configured for generating a first temperature range and a second side opposite to the first side configured for generating a second temperature range. The first airflow guiding unit is disposed at the first end or the second end of the duct module configured for guiding an airflow to enter through the first end, pass through the first side or the second side, and exit from the second end. The power module provides power required for operations of the temperature adjusting unit and the first airflow guiding unit.

An air conditioning device is provided, including an air duct module having a temperature adjusting unit, an energy conduction component, an airflow guiding unit and a control module. The temperature adjusting unit is disposed in the air duct module and has a first side configured for generating a first temperature range and a second side configured for generating a second temperature range.

The energy conduction component is disposed in the air duct module configured for conducting the energy generated by the first side or the second side of the temperature adjusting unit. The control module is configured for controlling on-off operations or configurations of the temperature adjusting unit and the airflow guiding unit.

A modular heat exchanger includes: two finned heat sinks, each finned heat sink has multiple guiding plates and a mounting recess; a securing assembly for securing the two finned heat sinks; a heat conduction pipe mounted in the mounting recesses; multiple modular blocks linearly arranged, and each modular block has multiple inlet through holes and multiple outlet through holes; multiple water pipes, each water pipe has two ends mounted through the inlet through holes and the outlet through holes respectively; and multiple coolers mounted to an outer sidewall defined on at least one of the modular blocks. It is convenient to assemble, disassemble or expand the modular heat exchanger, so as to improve performance of the modular heat exchanger. When one of the coolers fails, it is able to reach and detach said failed cooler by disassembling some parts of the modular heat exchanger, which is convenient.

A control apparatus includes a sensor and a control circuit. The sensor obtains a thermal pattern formed by a plurality of thermo-elements arranged in an appliance control device, a temperature of heat generated by each of the plurality of thermo-elements being controllable. The control circuit controls an appliance in accordance with the thermal pattern obtained by the sensor.

A coaxial ventilator (20) exchanges atmosphere between parts of a building (22) that are at differing heights. The coaxial ventilator (20) includes an outer conduit (24) that extends from an upper end (42) thereof downward to a lower end (44) thereof. The outer conduit (24) surrounds an inner conduit (62) that extends substantially the entire length of the outer conduit (24). Both the outer and inner conduits (24, 62) are open at their respective upper ends (42, 66) and lower ends (44, 68). Temperatures of atmosphere both surrounding and within the outer conduit (24) and the inner conduit (62) induce an exchange of atmosphere between the coaxial ventilator (20) and surrounding atmosphere.

A transportable PCM (phase change material) module comprises a number of PCM packs; a housing for thermally insulting said number of PCM packs from a module's surrounding medium; spaces separating said packs and forming one or more channels for the flow of a fluid; said housing incorporating a fluid inlet and a fluid outlet; whereby, in use, fluid flows through said channels from said inlet to said outlet. A PCM (phase change material) pack comprises a laminate of a first conducting panel and a second conducting panel enclosing a portion formed primarily of PCM; wherein said portion of PCM incorporates thermal conductors.

A humidifying device includes an air inlet, an internal air passage through which air taken in from the air inlet passes, a first thermometer that measures a temperature of the air taken in from the air inlet, a first hygrometer that measures a humidity of the air taken in from the air inlet, a cooler installed in a path of the internal air passage, and a cooling control unit that controls the cooler. The cooling control unit changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range.
