A system and method for obtaining environmental data—namely air quality information—from various devices contained within a structure is disclosed herein. The various devices contain sensors that can obtain environmental data, which is then analyzed by the system to determine if any level of a component within the data is outside of a predefined threshold range. If the system determines that the level of the component is outside of the predefined threshold range for that given component, the system will carry out certain steps in order to bring the level within the predetermined threshold range. These steps include selecting the appropriate appliance and the proper operating conditions to most efficiently bring the level back within the predetermined threshold range. Once the system has determined that the level is back within the predetermined threshold range, the system will instruct the selected appliance to turn OFF.

An air conditioning control device includes a control unit for controlling an air conditioning apparatus installed in a destination, based on user information relating to a user that moves to the destination.

A system includes first and second acquisition units that acquire first and second biological information of a target, and an estimation unit. The first acquisition unit includes at least one first sensor. The second acquisition unit includes at least one second sensor different from the at least one first sensor. The estimation unit estimates a thermal comfort of the target based on the first and second biological information. The estimation unit further estimates a first thermal comfort of the target based on the first biological information, and the thermal comfort of the target based on the first and second biological information. When the second acquisition unit does not acquire the second biological information, the estimation unit sets, as the thermal comfort of the target, the first thermal comfort that is corrected using previous thermal comfort of the target estimated by the estimation unit based on at least the second biological information previously acquired by the second acquisition unit.

A temperature load management device is for use in exposing a user to a second environment for removing a first temperature load accumulated in a first environment. The temperature load management device includes the control unit as a main component. The control unit controls the second environment or makes a notification of a time to end the exposing of the user to the second environment, based on physiological information on the user.

The fan, motor and battery are placed in a housing. The housing comprises inlet and outlet ports. The pipe assembly comprises at least one pipe connected to the outer port of the housing. At least one pipe comprises a plurality of openings for transferring the air to user's body.

Perception of the relationship between a comfort level and environmental data is facilitated, and appropriate management of air-conditioning equipment is enabled. A comfort level display apparatus has a preference storage unit to store a preference of a user regarding an air-conditioned environment, an attribute storage unit to store an attribute of the user, an environmental data value acquisition unit to acquire an environmental data value representing a condition in an air-conditioned space, a comfort level value generation unit to generate a comfort level value indicating comfort of the user in the air-conditioned space, based on the preference of the user stored the preference storage unit, the attribute of the user stored in the attribute storage unit, and the environmental data value of the air-conditioned space acquired by the environmental data value acquisition unit, a display data generation unit to generate display data by synthesizing the comfort level value of the user generated by the comfort level value generation unit and the environmental data value of the air-conditioned space acquired by the environmental data value acquisition unit, and a display unit to display the display data.

The present invention relates to a method for determining a set of optimized control parameters (Θ.sub.k) of a closed-loop controller (3) or an open-loop controller for an HVACR (heating, ventilation, air conditioning and refrigeration) system (2). In a first method step, an outside temperature (T.sub.A), an actual room temperature (T.sub.R) of a room (9), a supply temperature (T.sub.VL), a predefined target room temperature (T.sub.R,W), and a predefined target supply temperature (T.sub.VL,W) are detected. From the detected measured values (T.sub.A, T.sub.R, T.sub.R,W, T.sub.VL, T.sub.VL,W) and a time (t.sub.k) of detection data packet (D.sub.k) is generated, which is transmitted via an internet connection to a server (8) where the data packet (D.sub.k) is stored in a storage medium (6, 7) connected to the server (8). In the next method step, a set of optimized control parameters (Θ.sub.k) is calculated on the basis of the measured values (T.sub.A, T.sub.R, T.sub.R,W, T.sub.VL, T.sub.VL,W) of the transmitted and stored data packet (D.sub.k) and on the basis of measured values (T.sub.A, T.sub.R, T.sub.R,W, T.sub.VL, T.sub.VL,W) of a plurality of further data packets (D.sub.0 . . . k) generated at an earlier time (t.sub.. . . k) of a specified period (Δt) and/or at least one of a plurality of previously determined sets of optimized control parameters (Θ.sub.k-1) by executing a calculation algorithm on the server (8). In the following method step, the calculated set of optimized control parameters (Θ.sub.k) is stored in the storage medium (6, 7) connected to the server (8) and is transmitted via the internet connection to the closed-loop controller (3) or the open-loop controller of the HVACR system (2) or to a user (B) of the HVACR system (2).

The present application relates to an environment control system. The environment control system is capable of detecting variations of natural environment and artificial environment, and control the use of electronic devices automatically or semi-automatically. Based on collected information stored in a built-in storage module, the environment control system may calculate and learn the user's habit of use with respect to the electronic devices using network connection.

In an air-conditioning apparatus, in the case where a compressor is in operation, a fan is in operation, a wind guide plate is in a first state and a second heat exchanger operates as a condenser, when a detected temperature of target space for air-conditioning is higher than a set temperature for the target space and a detected temperature of a second heat exchanger is lower than or equal to a first reference temperature, a controller performs a first control to keep the compressor and the fan in operation and switch the state of the wind guide plate from the first state to a second state.

A system includes a processing circuit configured to provide an energy use setpoint based on energy data including an energy characteristic and subject to a constraint based on a variable condition of a building. The processing circuit is configured to estimate a value for the energy use setpoint that will result in the variable condition of the building satisfying the constraint and provide a control signal for equipment based on a difference between the energy use setpoint and a measured energy use.
