Disclosed are an Internet of Things (IoT)-based smart hybrid dehumidification system capable of reducing energy consumption, that is, the usage of a heater by using the condensation heat of a pre-cooler as a heat source for heating a rotor for releasing moisture in a dehumidification device to the outside, and a control method therefor. The IoT-based smart hybrid dehumidification system includes a sensing unit provided in a dehumidification space, a direct heating unit configured to suction humid air and supply dehumidified dry air to the dehumidification space, a direct digital controller (DDC) configured to control the direct heating unit, and a user terminal configured to remotely control the DDC in real time according to a sensing signal sensed by the sensing unit, and thus it is possible to maximize user convenience.

A method for an automatic direct expansion rooftop heating and cooling equipment sequence control, including the steps of determining capacity of the unit via temperature drop or rise and stabilization over a given time period; automatically adjusting a deadband around a setpoint, with the purpose of reducing or eliminating fixed staged compressor cycling while controlling supply air temperature or dewpoint or other sensor input.

A portable conditioner to cool or heat an internal space separate from an external space includes a control and command unit configured to determine at least the enthalpy difference between the internal space and the external space, and to regulate the quantity of air exchanged with the external space in relation to the enthalpy difference determined with respect to an expected value of enthalpy difference corresponding to a conditioning temperature and to a defined conditioning relative humidity. The present invention also concerns a method to regulate the portable conditioner.

An air conditioning robot according to an embodiment of the present disclosure includes: a main body having a suction hole and a discharge hole; a cooling cycle including a compressor, a condenser, an expansion mechanism, and an evaporator, which are disposed within the main body; a blower fan configured to blow air suctioned through the suction hole so that the air is heat-exchanged with the evaporator and discharged through the discharge hole; a heat storage tank configured to accommodate a heat storage material in which heat of the condenser is stored; a heat dissipation part configured to dissipate the heat of the heat storage material accommodated in the heat storage tank, the heat dissipation part thermally contacting a heat transfer terminal disposed outside the main body; and a driving part configured to allow the main body to move so that the heat dissipation part thermally contacts or is thermally separated from the heat transfer terminal.

An air duct switching component having an air outlet cover defining an air inlet, a first air outlet and a second air outlet, and being arranged such that the air inlet communicates with a fan air outlet; and an air switching plate disposed on the air outlet cover, configured to move between a first position to close the first air outlet and to open the second air outlet and a second position to open the first air outlet and to close the second air outlet, and wherein in the first position, the fan air outlet communicates with a body air outlet via the air inlet and the second air outlet, and wherein the first air outlet is disposed relative to a humidifier such that in the second position, the fan air outlet communicates with the body air outlet via the air inlet, the first air outlet and the humidifier.

An air-conditioning, system includes a cabinet with a partition dividing an internal space of the cabinet into an indoor compartment and an outdoor compartment. An evaporator, a compressor and an internal fan are disposed in the indoor compartment. A condenser and an external fan are disposed in the outdoor compartment. The cabinet is provided with an internal air inlet corresponding to the internal fan, an internal air outlet corresponding to the evaporator, an external air inlet corresponding to the external fan, and an external air outlet corresponding to the condenser. The air-conditioning system is of a cabinet structure as a whole, has a small size and occupies a small space. An air flow of the internal fan is completely separated from an air flow of the external fan, so that internal circulating air and external circulating air are effectively prevented from being mixed, and the refrigerating effect is improved.

HVAC system includes a front side access panel, an HVAC unit, a mounting sleeve, and a back side grille. The mounting sleeve and the HVAC unit are configured to fit within the preexisting framing of a building, and in particular to be mounted in a wall, between pre-existing studs, of a room. The HVAC unit can be installed into the mounting sleeve via quick connect mechanisms including, but not limited to, snap in connections and/or tab and slot features. The mounting sleeve enables rapid installation and also condensate collection. The HVAC unit includes separate modular units, e.g. an evaporator module unit, a mechanical module unit, and a condenser module unit, that are mounted and interconnected to each other. The HVAC system includes vertically oriented HVAC components and component connections that are self-aligned, and can be further configured with a horizontal configuration portion for multi-zone capability.
