An adiabatic cooling system including a controller is operable to determine a time period between a first cycle in a recovery mode and a second cycle in the recovery mode. If the time period is less than a first preset time period, then there is a first time lapse before the controller enters the fluid supply mode, and if the time period is greater than a second preset time period, then there is a second time lapse before the controller enters the fluid supply mode, and the first time lapse is greater than the second time lapse.

A manifold assembly includes a body and a damper assembly. The body defines a first opening, a second opening, outlet third opening, and a fluid plenum. The fluid plenum fluidly couples the first opening, the second opening, and the third opening. The damper assembly includes a first damper, a second damper, and a connecting member. The first damper is disposed within the fluid plenum proximate to the first opening. The second damper is disposed within the fluid plenum proximate to the second opening. The connecting member is coupled to both the first damper and the second damper and is configured to move the first damper and the second damper to selectively open one of the first opening or the second opening while closing the one not opened.

A ventilation system includes: a housing including a first inlet drawing outdoor into the housing, a second inlet drawing room air into the housing, a first outlet discharging outdoor air into an indoor space, and a second outlet discharging room air to an outdoor space; a total heat exchanger exchanging heat between the outdoor air and the room air; a first heat exchanger between the first inlet and the total heat exchanger; a second heat exchanger between the first inlet and the first heat exchanger; a compressor supplying a refrigerant to the first heat exchanger and the second heat exchanger; a four-way valve switching a flow direction of the refrigerant; a first expansion device at an inlet of the first heat exchanger expanding the refrigerant; a second expansion device between the first heat exchanger and the second heat exchanger and expanding the refrigerant; and at least one processor.

Implementations described and claimed herein provide systems and methods for evaporative cooling control. In one implementation, a humidity setpoint is received for a designated space, and at least one atmospheric condition of ambient air is received. The at least one atmospheric condition is measured using one or more ambient air sensors. A performance prediction of an evaporative cooler is generated by calculating a set of one or more predicted psychrometric properties of supply air leaving the evaporative cooler based on the at least one atmospheric condition. The humidity setpoint is compared to the set of one or more predicted psychrometric properties of the performance prediction in a setpoint comparison. A flow of fluid is controlled over evaporative media using one or more pumps of the evaporative cooler. The flow of the fluid is controlled based on the setpoint comparison such that the humidity setpoint is prevented from being exceeded.

Liquid micronization apparatus according to the present disclosure includes: water storage that stores water to be micronized; water supplier that supplies water to water storage; drainage that drains water stored in water storage; remaining water amount acquirer that acquires a remaining water amount of water storage; transition determiner that determines a transition from a value greater than or equal to a remaining water amount threshold to a value less than the remaining water amount threshold; and water supply/drain controller that discharges all water in water storage by water drainage and supplies water to water storage by water supplier in a state where water storage does not have water when transition determiner determines the transition during micronization.

An environment control system is an environment control system that controls an environment of a target space. The environment control system includes: an obtainer that obtains biological information of a person present in the target space and environmental information of the target space; an estimator that estimates, based on the biological information and the environmental information obtained by the obtainer, a position of the person in the target space and a condition level indicating a level of comfort felt by the person in regard to the environment; a generator that generates, based on the position and the condition level of the person estimated by the estimator, a control signal that controls an operation of a device provided in the target space; and an outputter that outputs the control signal generated by the generator to the device.

An air purifier and methods to sterilize an internal surface of an air purifier. The air purifier includes a removable particulate or gas filter, an air flow generator, a controller for said air flow generator, a first air flow setting with an air filtration air flow speed, and a second air flow setting which correlates with sterilization of an internal surface of the air purifier and/or removable particulate or gas filter. The air flow speed measured at the removable filter at the second air flow setting is from 0.1 to 1.2 cms.sup.1.

An air supply system moderates excess energy consumption occurring in fans. A second unit includes a second fan that supplies first air to a target space. A duct sends the first air sent from a first unit by a first fan to the second unit. A remote sensor acting as a first detector detects information about second air in the target space. A main controller acting as a first controller communicates with the second unit and the remote sensor. The second unit includes a second detector that detects the air flow volume sent by the second fan, and a sub-controller acting as a second controller that controls the rotation speed of the second fan. The main controller determines a target air flow volume of the second unit on the basis of the information about the second air acquired from the remote sensor, and transmits an instruction indicating the target air flow volume to the sub-controller. The sub-controller controls the rotation speed of the second fan such that the air flow volume detected by the second detector approaches the target air flow volume.

A smart artificial intelligence based mobile robot having an air purification, humidification, dehumidification, and ultraviolet cleaning-based system to remove pathogens is disclosed. The robot also acts as an emergency alert system for break-ins and human fall detection using AI algorithm. The mobile robot operates and navigates intelligently using real time data collected from the environment through various sensors and input devices. An object detection module may use inputs from the camera to recognize people, pets, and others by pre-trained machine learning data set. The mobile purification, humidity management and sanitizing robot includes a ball bearing for balance and a motor controller, which drives two motors and wheels. The central controller of the smart mobile robot system has memory and processor to handle navigation, communication, notifications, and air handling system through real time data collection.

An HVAC system includes a first air quality sensor and a second air quality sensor. The system contains a controller which calculates a differential between the first air quality sensor and the second air quality sensor. The differential is compared to a threshold. If the threshold is satisfied, a fan is engaged which may, reducing the air quality differential as sensed by the first and second air quality sensor.
