Some embodiments of the present disclosure provide an air conditioning system. The air conditioning system includes: a housing, having an indoor air supply port; a first heat exchanger, disposed in the housing, an air outlet of the first heat exchanger being communicated with the indoor air supply port; a first air supply mechanism, disposed in the housing, an air outlet of the first air supply mechanism being provided correspondingly to an air inlet of the first heat exchanger; and a plurality of replaceable assemblies, wherein each of the plurality of replaceable assemblies can be assembled in the housing, and the housing is selectively cooperated with one or more of the plurality of replaceable assemblies.

An example refrigeration system includes an indoor fluid loop, an outdoor fluid loop, and a heat exchanger assembly. The indoor fluid loop circulates a first working fluid. The outdoor fluid loop circulates a second working fluid that is different from the first working fluid and is separated from the indoor fluid loop by a wall of a structure. The heat exchanger assembly is mounted within the wall of the structure. The heat exchanger assembly includes a heat exchanger and a housing, where the heat exchanger is disposed within an internal space defined by the housing. The housing supports the heat exchanger within the internal space and is mounted to a structure of the wall.

An assembly for use in mounting an object in an opening in a structural member, the structural member having opposing first and second surfaces, the assembly including a housing that is sized and shaped to define an interior to house the object and that can be received within the opening in the structural member, a trim ring sized and shaped to fit within the interior of the housing and to bear against the second surface of the structural member, and a cover having a first panel sized and shaped to cover the trim ring, the cover having a connector that releasably connects the cover to the housing, the cover further including at least one standoff extending therefrom that is sized and shaped to bear against the trim ring to hold the trim ring in place.

An improved air quality monitoring device provides accurate and reliable predictions regarding likelihood for microbial growth on building walls. The present invention comprises a housing adapted to affix the device to a building wall, a first sensor array placed in close proximity to the wall, a second sensor array and a processing means operatively connected to the first sensor array and the second sensor array. The first sensor array provides inputs such as relative humidity at the surface of the wall, the wall temperature and wall pressure. The second sensor array provides inputs such as relative humidity, temperature pressure and quality of ambient air. Using inputs from the first sensor array and the second sensor array, the processing means generates an output representative of the likelihood of microbial growth and the likelihood that the wall moisture is caused by condensation. A system of networked monitoring devices is also described.

A ventilation device for ventilating rooms, has a first air routing device for routing a first flow of air, the routing device having a first room-side outlet, a first flow space in which at least one first fan capable of bidirectional operation is arranged, and a first outside outlet; a second air routing device for routing a second flow of air, which is fluidically completely separate from the first air routing device and has a second room-side outlet, a second flow space in which at least one second fan capable of bidirectional operation is arranged, and a second outside outlet; an integral gas-solid heat exchanger adapted to route the first flow of air and the second flow of air in a respective set of passageways, in a fluidically separated but thermally coupled manner, wherein the solid in the first and the second air routing device additionally forms a respective regenerator.

A supply and/or cooling system contains a supply tube or a supply channel for receiving a liquid and/or a gas, which is coupled to a liquid supply device and/or a gas supply and/or gas suction system and has at least one liquid and/or gas discharge opening in a tube, and a channel base or casing region. A strand-shaped ingredient carrier and/or cooling strand is suspended on the supply tube or the supply channel and/or the supply tube or supply channel coupled to the gas supply and/or a gas suction system is suspended below the at least one ingredient carrier and/or cooling strand. The ingredient carrier contains and/or carries at least one ingredient and the ingredient carrier and/or cooling strand can be supplied with the liquid and/or the gas via the liquid and/or gas discharge opening. The supply tube or the supply channel is vertically moveable.

A thermostat that is configured to be releasably secured to a wall mountable connector, wherein the wall mountable connector includes a jumper switch that permits an installer or other professional to easily form an electrical connection between different wiring terminals of the wall mountable connector in accordance with how particular field wires are connected to the wiring terminals of the wall mountable connector. The thermostat is further configured to automatically determine the position of the jumper switch of the wall mountable connector, and in some cases, change the control of at least some functionality of the thermostat and/or HVAC equipment depending on the position of the jumper switch.

A load unit includes a water circuit chamber configured to accommodate at least a part of a water circuit configured to allow water to flow therethrough, a fan, an air inlet formed at a height positioned different from that of the air inlet and configured to suck indoor air therethrough, an air outlet configured to blow indoors the air sucked through the air inlet, and an air passage formed between the air inlet and the air outlet so as to be isolated from the water circuit chamber. A load-side heat exchanger is provided in the air passage.

An example refrigeration system includes an indoor fluid loop, an outdoor fluid loop, and a heat exchanger assembly. The indoor fluid loop circulates a first working fluid. The outdoor fluid loop circulates a second working fluid that is different from the first working fluid and is separated from the indoor fluid loop by a wall of a structure. The heat exchanger assembly is mounted within the wall of the structure. The heat exchanger assembly includes a heat exchanger and a housing, where the heat exchanger is disposed within an internal space defined by the housing. The housing supports the heat exchanger within the internal space and is mounted to a structure of the wall.

A ventilation apparatus for ventilating a building. The ventilation apparatus comprises a casing comprising: a cavity for housing a removable heat-exchange cartridge; a service door providing access to the cavity; a primary and secondary pathways fluidly connecting the inside of the budding to the outside of the budding, wherein the primary pathway and the secondary pathway cross the cavity along about perpendicular axes; a primary ventilator for forcing an airflow in the budding through the primary pathway; and a controllable secondary ventilator for forcing a controllable airflow through the secondary pathway. The ventilation apparatus, when the casing houses the heat-exchange cartridge, has the primary ventilator forcing an inflow of air through the primary pathway, and (ii) the controllable second ventilator for controllably forcing either an outflow or an inflow of air through the secondary pathway. The ventilation apparatus, without heat-exchange cartridge, has only inflow(s) forced through the pathway(s).
