A new thermal system utilizing removable heat pump modules to decrease servicing time and complexity, increase the range of refrigerants safely usable, increase the efficiency of many thermal systems, and serve new industrial thermal needs. Safe use of potentially toxic and flammable refrigerants is enabled by enclosing the heat pump modules within a hermetic enclosure with multiple overpressure safeties employed. The tool necessary for servicing these thermal systems without any refrigerant leakage is included.

A low-profile air purifier comprises a housing that includes a pair of plates opposing one another, an intake opening and an output opening; a toroidal fan rotatably mounted in the housing between the plates, an axis of the toroidal fan being essentially perpendicular to the plates; a motor disposed in a central opening of the toroidal fan for rotating the toroidal fan; and a filter mounted to the housing for filtering air flowing through the housing. The present patent application also discloses a modular wall section that comprises an internal frame; an air purifier mounted within the internal frame; and a panel mounted in the internal frame for movement between an open position for accessing the air purifier and a closed position concealing the air purifier. The air purifier of the modular wall section may have similar configuration as the above discussed low-profile air purifier.

A modular element for a façade of a building may include: an air conditioning unit; and a channeling system. The channeling system may be configured to receive fluid from an external source. The channeling system may include at least one first channel entering the air conditioning unit. The external fluid source may include a pump configured to circulate the fluid inside the channeling system. The channeling system further may include one or more inlets configured to connect to the pump so as to receive the fluid from the external source and input the fluid into the at least one first channel of the channeling system. The channeling system further may include at least one second channel configured to connect to an internal diffusion element of the building. The at least one second channel may be configured to transport the fluid from the external source to the internal diffusion element.

A portable air cooler is fashioned as a storage chest for ice cubes, dry ice, or other pre-chilled articles such as reusable freezable blocks. Sidewalls of the chest include air intakes, and a baffle forces intake air to pass by or through the chilled articles to that the air is cooled by heat exchange. Fans in the chest lid exhaust the cooled air, which may be used to cool waste heat from a heat-producing device lain atop the chest. The lid also includes stand-offs to allow airflow under the device being cooled, and guardrails help maintain the device in position over the fans providing cooling air and prevent the device from being casually knocked off the top of the lid of the chest.

A multi-use system for influencing organic matter in an environmentally controlled room is provided with a modular dehumidification system. The modular dehumidification system includes a head unit, with separate cooling and heating subcircuits, and multiple modular dehumidifier units. Each modular dehumidifier unit has a cooling coil operable to cool and/or dehumidify the air and a heating coil operable to heat the air, for example, to raise room temperature and/or offset heat loss arising during dehumidification. The cooling coils are connected to the head unit in parallel to one another and the heating coils are connected to the head unit in parallel to one another. The number of modular dehumidifier units installed in the system is selected to provide the system with the desired maximum capacity. The control system may be configured to activate the appropriate number of cooling and heating coils, and to control the operation of each active coil.

An air treatment system is disclosed that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions. In more detail, the modules can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. The fan module can include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.

The invention is directed to a modular gas flow system comprising at least a first and a second hollow cuboid shaped gas flow element. The four edges of at least one open face of the first gas flow element is connected in a gas tight manner to four edges of an open face of the second hollow cuboid shaped gas flow element. A valve or a partition is present at the connecting open faces. The gas flow system may be a header of a plate heat exchanger.

A tubular-shaped and modular air handling unit (AHU) for heating, ventilating, and air conditioning (HVAC) systems is disclosed. In some embodiments, a modular AHU is disclosed that may include a coil module, a fan module, and an electrical module; each of which may be tubular shaped for easily coupling one to another and easily coupling to tubular-shaped (or round or circular) ductwork. Further, in the tubular-shaped and modular AHU, each module may be independent and stand alone, thereby allowing for relatively easy upgrading, replacement, and/or servicing.

The invention relates to an air conditioning module, a modular air conditioning system, a transport vehicle and a method. The air conditioning module the air conditioning module (51) comprises an evaporator (65), a condenser (66) and a compressor (67) which are mounted to, onto or in the frame (60). The frame (60) further defines or bounds a first volume V1 that is arranged in air communication with the evaporator (65) and a second volume V2 that is arranged in air communication with the condenser (66). The second volume V2 is separated from the first volume VI, at least in the lateral direction T. The frame (60) is provided with one or more walls (71), (72), (73), (74) to at least partially define or bound the first volume V1 and the second volume V2. The first volumes V1 are aligned in the stacking direction S to form the continuous first air channel C1.
