A single-package air conditioner unit, as provided herein, may include a cabinet, an outdoor heat exchanger, an indoor heat exchanger, a compressor, and a controller. The cabinet may define an outdoor portion and an indoor portion. The outdoor heat exchanger may be disposed in the outdoor portion. The indoor heat exchanger may be disposed in the indoor portion. The compressor may be in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant therebetween. The controller may be in operative communication with the compressor. The controller may be configured to initiate a conditioning operation. The conditioning operation may include receiving a demand response signal corresponding to electric power access, determining occupancy of an indoor environment, and initiating a responsive conditioning cycle in response to receiving the demand response signal, the responsive conditioning cycle being based on the determined occupancy.

Systems and methods are provided herein for determining motion in a volume using a lighting based sensor. A status of a light is determined with which a motion sensor is associated. Motion measurements are received from the motion sensor. Based on the motion measurements, a motion score is determined. A room status is adjusted based on the motion score.

Inference server and environment controller for inferring one or more commands for controlling an appliance. The environment controller receives at least one environmental characteristic value (for example, at least one of a current temperature, current humidity level, current carbon dioxide level, and current room occupancy) and at least one set point (for example, at least one of a target temperature, target humidity level, and target carbon dioxide level); and forwards them to the inference server. The inference server executes a neural network inference engine using a predictive model (generated by a neural network training engine) for inferring the one or more commands based on the received at least one environmental characteristic value and the received at least one set point; and transmits the one or more commands to the environment controller. The environment controller forwards the one or more commands to the controlled appliance.

Climate control systems and related methods and systems therefore a disclosed. In an embodiment, the climate control system includes a heat exchanger configured to discharge conditioned air to an indoor space. In addition, the climate control system includes a display and a controller coupled to the display. The controller is to generate an operation selection option on the display. The operation selection option includes a plurality of selections for operating of the climate control system based on operational efficiency or occupant comfort within the indoor space. The controller is to adjust a temperature of the heat exchanger relative to a user selection from the plurality of selections.

A variable air flow air conditioning (HVAC) systems and methods are disclosed. In example embodiments, one or more variable speed fans or air-moving devices are in communication with ducts connecting one or more zones of a structure or other space to be air conditioned. Zone temperature sensors and air flow measurement are provided to obtain particular measurements relative to the zone it is serving while communicating with a central control. Optionally, a distributed control system can be provided such that zone sensors communicate with both the central control and its respective zone controller. The control system collects and processes multiple datasets to dynamically and proportionally adjust the volumetric air flows of each of the zones to satisfy any loads or heating/cooling demands while also maintaining a net volumetric air flow across a coil of the indoor heat transfer unit within a preset range. In some example embodiments, enhanced variable air flow air conditioning (HVAC) systems and methods are disclosed.

The systems and methods described herein provide for a novel deep learning approach to estimating and predicting faulty mechanical system conditions before they occur without using any measurements from the system itself. Environmental data, such as temperature, humidity, occupancy, volatile organic compounds (VOC), equivalent carbon dioxide (eCO2) and particulate matter may be used in the estimation and prediction of faults, failures, and other inefficiencies within the HVAC system.

An air conditioning unit is disclosed. The air conditioning unit may include a makeup air system having a makeup air duct with a first end and a second end. The makeup air duct may be separate structure built in a bottom plate of the air conditioning unit and define an air flow passage in fluid communication between the first end and the second end to allow makeup air to flow therethrough.

Disclosed herein is a diffuser air purification unit. The diffuser air purification unit can comprise a diffuser, a filtration chamber, a purification chamber, a blower, a housing, and a control module. The filtration chamber can be configured to receive air through the diffuser from an external setting in which the diffuser air purification unit is installed and to cause a filtration of the air when the air flows through the filtration chamber. The purification chamber can be configured to receive the air from the filtration chamber and to cause a purification of the air when the air flows through the purification chamber. The blower can be configured to intake the air from the external setting through the diffuser, the filtration chamber, and the purification chamber and to expel the air into the external setting. The housing can at least partially enclose the filtration chamber and the purification chamber. The control module can be secured to the housing and be configured to control an operation of the diffuser air purification unit.

The air conditioner includes a thermal image acquirer that acquires a thermal image indicating a temperature distribution inside the air-conditioned space, and a thermal sensation estimator that estimates the thermal sensation of a person in the air-conditioned space based on the thermal image obtained from the thermal image acquirer and a parameter set in the air conditioner, the parameter prescribing at least one of a wind direction, a wind speed, and a wind temperature of wind emitted from the air conditioner.

An air-conditioning system includes a refrigerant system in which an outdoor unit, one or more indoor units, and one or more ventilators are connected by a refrigerant pipe and in which refrigerant circulates, and a control device configured to control the refrigerant system. The control device includes a target temperature adjustment unit configured to adjust a target evaporating temperature based on a detection value detected by a temperature and humidity detection unit provided to at least one of the indoor unit and the ventilator that satisfies a specific criterion, and an air-conditioning control unit configured to control the refrigerant system such that the evaporating temperature of each of the indoor unit and the ventilator is equal to the target evaporating temperature adjusted by the target evaporating temperature.
