A system for assessing an indoor space for favorable conditions for the transmission of a viral particle is disclosed. A set of sensors measure a set of environmental parameters, and a processor is configured to combine the measured set of environmental parameters into a single scale of numerical or descriptive value representing the favorability of viral transmission in the indoor space.

An air conditioning system control device 10 includes: a switching unit 11 that, when a parameter relating to the indoor environment in which the air conditioning system operates does not satisfy a first condition while the air conditioning system is operating in a first operation mode that is an operation mode in which setting values computed on the basis of a prediction model are used as the setting values for the air conditioning system, switches the operation mode of the air conditioning system to a second operation mode that is an operation mode in which the computed setting values are not used as the setting values for the air conditioning system.

An automated method for implementing UV-C light for air purification in hotel rooms is disclosed. By implementing a method for identifying the hotel room rental status and occupancy status, the UV-C light can be automated to a specific cycle time that will not cause issues with guest complaints or potential safety issues.

An air sanitization and purification system controlled by a thermostat in wired or wireless communication with an ultraviolet germicidal irradiation light or bipolar ionization appliance, with operation of the light or appliance controlled according to a pre-defined operation schedule of a heating, ventilation and cooling (HVAC) system or by receipt of sensor data indicating the presence of a person with an enclosed area heated or cooled by the HVAC system.

Disclosed are techniques relating to an improved air quality device that can provide personalized comfort and improved air quality elements to occupants of a common space. The improved air quality device can comprise a plurality of individually adjustable directional outlets. The state of these individually adjustable directional outlets can be updated to individually satisfy comfort levels of various occupants at different locations within the common space, which can be determined based on inputs from a control device (e.g., thermostat), a sensor (e.g., occupancy sensor), and so forth. The improved air quality device can further comprise an ultraviolet light device that can reduce pathogens in the common space. The state of the ultraviolet light device (e.g., on/off, duration of on/off, a position/location, and so on) can be a function of the state of the state of the outlets.

A wireless thermostat may be associated with a user account of an external web service that may facilitate remote access and/or control of the wireless thermostat. A remote device may be used to access a user's account hosted by the external web service. The wireless thermostat may be identified to the external web service and associated with the user's account by one or more unique identifiers previously delivered to the remote device from the wireless thermostat.

The present disclosure provides systems and methods for controlling environmental systems including a processor, a communication subsystem in electronic communication with the processor and adapted to enable electronic communication between the controller, a storage device and an environmental system, and context detection means in electronic communication with the processor, the context detection means adapted to automatically detect a change of context such that when the change of context is detected, comparing at least one setting with a corresponding current setting of the environmental system and if the setting does not match the current setting, adjusting the at least one environmental system to match the at least one setting of the at least one environmental system.

A heating control device includes an estimating unit to estimate a latent heat load of air present in a ventilation target space as a ventilation target and a heating control unit to control, in accordance with the latent heat load estimated by the estimating unit, a temperature of heating outside air by a heat exchanger to heat outside air supplied to the ventilation target space, via control of a condensation temperature of a refrigerant in the heat exchanger. The estimating unit estimates the latent heat load from ΔX, which is a value obtained by subtracting, from a target absolute humidity (X0) set by a temperature/humidity setting device to set a target humidity of an interior as the ventilation target space, an absolute humidity (Xi) of the interior detected by an indoor humidity sensor.

A server and a controlling method of a server are provided. The server includes a communication interface, a memory configured to store priorities of each of a plurality of spaces, and a processor configured to control a plurality of air conditioners arranged in the plurality of spaces, and the processor may, based on a total power usage of the plurality of air conditioners exceeding a first threshold value, control the plurality of air conditioners to operate in a power peak control mode to reduce the total power usage, and based on the total power usage being less than a second threshold value while operating in the power peak control mode, control the plurality of air conditioners to sequentially switch to a general mode according to the priority.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for temperature control. In some implementations, a method includes obtaining first temperature data associated with a first climate control component of a first dwelling of a property; obtaining second temperature data associated with a second climate control component of a second dwelling of the property; determining a leak effect between the first dwelling and the second dwelling using the first temperature data and the second temperature data; determining an instruction to adjust operation of the first climate control component using the leak effect; and providing the instruction to the first climate control component.
