摘要： A controller for heating, ventilation, or air conditioning (HVAC) equipment operable to affect an environmental condition of a building is configured to obtain predictive models that predict values of an energy control objective and an air quality control objective as a function of control decision variables for the HVAC equipment. The controller executes a multi-objective optimization process using the predictive models to produce multiple sets of optimization results corresponding to different values of the control decision variables, the energy control objective, and the air quality control objective. The controller selects one or more of the sets of optimization results based on the values of the energy control objective and the air quality control objective. The controller operates the HVAC equipment to affect the environmental condition of the building in accordance with the values of the control decision variables corresponding to a selected set of the optimization results.

摘要： The present invention relates to an air purification device. The housing includes a main passage section through which air is introduced from a room through a main inlet port and is discharged to an outside through a main outlet port, and a bypass passage section partitioned from the main passage section, through which air is introduced from the room through a bypass inlet port and is discharged to an outside through a bypass outlet port. The main inlet port damper opens and closes the main inlet port. The main outlet port damper opens and closes the main outlet port. The bypass damper opens and closes the bypass passage section. The controller is configured to control the bypass damper so as to open the bypass passage section when the main passage section is closed due to a malfunction of the main inlet port damper or the main outlet port damper.

摘要： A condensate tray assembly for use below a condensate generating appliance, particularly a refrigeration unit. The assembly comprises a tray (1) with an inlet (3A) and an outlet (3) towards the bottom of the tray. A self-priming pump (5) is connected to the outlet for pumping liquid from the tray. A sensor (12) within the tray determines the rate of change of the depth of liquid. A control system (14) receives an input from the sensor (12) to control the pump (5) to pump liquid from the tray and to turn off the pump based on the rate of reduction of the depth of liquid in the tray. The invention also extends to a method of operating the pump.

摘要： In one aspect, a heat exchanger system is provided that includes a cooling system and a sensor configured to detect a variable of the cooling system. The heat exchanger system includes processor circuitry configured to provide the variable and a plurality of potential operating parameters of the cooling system to a machine learning model representative of the cooling system to estimate at least one of energy consumption, water usage, and chemical usage for the potential operating parameters. The processor circuitry is further configured to determine, based at least in part on the estimated at least one of energy consumption, water usage, and chemical consumption, for the potential operating parameters, an optimal operating parameter of the cooling system to satisfy a target optimization criterion.

摘要： [Object] To provide a management apparatus and an air conditioning management system by which the objectivity of a comfort level evaluation relating to a smell in a room can be enhanced and a comfort level can be evaluated also with respect to an unknown smell.
[Solving Means] A management apparatus according to an embodiment of the present invention includes a detecting unit, an input unit, a storage unit, and a control unit. The detecting unit detects a smell in a room. The input unit is operated by a user who enters the room and acquires a sensory evaluation of each user which relates to the smell in the room when the user enters the room. The storage unit accumulates evaluation data obtained by associating an output of the detecting unit and an output of the input unit with each other and stores a plurality of attributes relating to a comfort level of the smell in the room, the attributes being classified on the basis of the evaluation data. The control unit determines which of the plurality of attributes the output of the detecting unit belongs to.

摘要： A heating, ventilation, and air conditioning (HVAC) system may be zoned into one or more zone. The HVAC system may include HVAC components, sensors, and one or more register vents that may include vent dampers (e.g., electronically controllable vent dampers or manually operated vent dampers). Opening and closing of the vent dampers may facilitate creating zones or sub-zones in the HVAC system configuration. An HVAC control system may receive a request for conditioned air in one or more of the zones, determine a damper setting for at least one of the vent dampers, communicate the determined damper setting to a vent damper or user interface, determine which HVAC components should be active, if any, and/or provide controls signals to activate or keep active the HVAC components that are determined to be active.
