An embodiment provides an air conditioner, including: an outer housing that contains therein one or more of a condenser, a compressor, coils, a fan, an enclosure air intake, and an enclosure air return; one or more rainwater drains configured to transmit rainwater that enters the housing through the outer housing to ambient; and one or more condenser drains configured to transmit condensation from within the outer housing to an exterior location via one or more conduits.

A floor system for detecting refrigerant includes one or more tiles. Each tile includes a tile body having a cavity formed therein and a grille element positioned within the cavity of the tile body. The grille element is configured to receive air from at least one of above or below the tile body. Each tile further includes a control assembly associated with the grille element. The control assembly includes a refrigerant sensing device to detect refrigerant in the received air. The control assembly is configured to output a signal indicating a detection of refrigerant.

A method of improving the efficiency of the heat exchange system using variable superheat and sub cooling values for a wide range of ambient conditions is provided. The heat exchange system comprises an efficiency enhancing apparatus positioned between the condenser and evaporator. Data analytics software module and artificial intelligence techniques are used to obtain optimum system parameters for achieving maximum efficiency.

The present invention relates to a smart home controller refrigerator and a control method therefor, the smart home controller refrigerator, according to one embodiment of the present invention, comprising: a control unit comprising a control protocol communication unit for receiving control information for controlling a home appliance in a home, an operation protocol communication unit for generating an operation signal calculated from the control information, and a signal transmission unit for transmitting the operation signal to the home appliance; at least one storage space; and at least one door for controlling the opening/closing of the at least one storage space.

A system comprising a compressor, a first valve coupled to the compressor and coupled to a first coil, a first expansion valve coupled to the first coil, a second coil, and a second expansion valve. The second expansion valve coupled to a third coil, a second valve coupled to the compressor and the third coil. A controller operable to operate the first valve, the first expansion valve, the second expansion valve, and the second valve. The second coil is coupled to the compressor and the refrigerant flows from the second coil to the compressor.

An actively heated or cooled food container can have a lid movable between an open and a closed position and an insulated body to which the lid can be attached. The insulated body can have a sidewall that defines a perimeter of the container body and a base, the sidewall and base defining one or more chambers that can be sealed by the lid. The food container can have a temperature control system that can include one or more heating or cooling elements in thermal communication with one or both of the sidewall and the base and operable to heat or cool one or both of the sidewall and the base to thereby heat or cool the one or more chambers in the food container.

In one example, a heating and cooling garment system includes a garment, and a plurality of heating and cooling zones positioned within a portion of the garment. Each heating and cooling zone is configured to independently heat or cool based on heating and/or cooling instructions received from a mobile application executed on a wireless device.

A chiller system for supplying chilled water to a building is provided. Embodiments of the presented disclosure relate to chiller systems using a plurality of ergonomic control boxes. In some embodiments, the ergonomic control boxes are in wireless data communication with each other and/or with one or more sensors located outside of the control boxes. Embodiments of the present disclosure allow an operator to access the control panels without the use of a ladder or stairs. Embodiments of the present disclosure relate to a chiller system that does not require an operator to reach overhead in order to adjust the operations of the chiller system.

A system comprising a compressor, a first valve coupled to the compressor and to a first coil, a first expansion valve coupled to the first coil, and a second expansion valve. The second expansion valve coupled to a second coil. A second valve is coupled to the second coil and the compressor. A third valve is coupled to the compressor and a third coil. In response to receiving a heating demand that is below a threshold heating demand, a controller induces an artificial heating demand.

The disclosure features various embodiments and aspects of a chest for quenching beverages. The chest can include a tank for holding a chilled mixture of ice and water, an ice maker adapted for making ice having an output for ejecting ice into a conduit in fluid communication with the tank, and a plurality of quench trays disposed above the tank for holding containers of beverages located in first and second positions. The trays can be filled with cold water by way of a conduit in fluid communication with the tank. The quench trays can include a compartment defined by a bottom and a plurality of walls, and defining therein a plurality of rows for aligning and containing a plurality of beverage containers. The drawers can further include at least one drain orifice configured to guide water out of the quench tray.
