摘要： Systems and methods are provided for monitoring and controlling one or more environmental conditions of a building. The method comprises obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building. The method further comprises combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day. The method finally comprises operating HVAC equipment to drive the combined feedback toward a setpoint for the building.

摘要： The present disclosure provides a method for determining the size of the fresh air inlet performed by a computing device, and an indoor unit of an air conditioner. The computing device acquires an outputting air volume and a fresh air coefficient of the indoor unit of the air conditioner; calculates a cross-sectional area of the fresh air inlet, according to the outputting air volume and the fresh air coefficient of the indoor unit of the air conditioner; and calculates a diameter of the fresh air inlet, according to the cross-sectional area of the fresh air inlet. The indoor unit of the air conditioner having the fresh air inlet can improve the comfort in the indoor environment and user's experience satisfaction without adversely affecting the heat exchange efficiency.

摘要： A heating, ventilation, and/or air conditioning (HVAC) system has a refrigerant circuit that includes a compressor, a condenser system with a first set of tubes and a second set of tubes fluidly separate from the first set of tubes within the condenser system, and a valve positioned downstream of the compressor and upstream of the second set of tubes relative to a direction of refrigerant flow through the refrigerant circuit, in which the refrigerant circuit is configured to direct refrigerant through the first set of tubes and through the second set of tubes. The HVAC system further has a switch configured to detect an operating parameter and to instruct the valve to close based on the operating parameter such that refrigerant flow is blocked through the second set of tubes and refrigerant flow is enabled through the first set of tubes.

摘要： An air-conditioning apparatus includes a heat pipe, which performs heat exchange. The air-conditioning apparatus provides supply air in a set state (temperature, humidity) through a change in the flow passage of ventilation air and outside air by the selective opening/shutting of dampers, cooling the outside air by spraying mist, and cooling and humidifying the supply air. The cooling temperature and humidity of the supply air is controlled at a ratio of the ventilation air passing through a cooling coil and the ventilation air passing through a bypass passage. Using a bypass passage, ventilation air can directly move to an air supply block without the intervention of the cooling coil within a heat exchange block through which a ventilation air passes.

摘要： An air handling system includes a movable evaporative media section. The movable evaporative media section is movable between a closed position and an open position. When the movable evaporative media section is in an open position, the movable evaporative media section exposes an opening to the air flow and is positioned to allow at least a portion of the air flow in the volume to flow around the movable evaporative media section and through the opening.

摘要： A system and method for sampling air at multiple locations in a controlled environment. The system and method includes automatic adjustment of mass flow rates and duration of vacuum connections (either via time elapsed or indirectly by volume) based on rates set by an operator. Additionally, the system and method enables users to monitor and control aspects of the system via network-connected devices. Additionally, the system enable a vacuum pump to be disconnected from power in response to a physical emergency button, a software-based emergency stop button available on network connected devices, and an automatic power disconnection in response to an abnormal mass flow reading that could potentially impact the vacuum pump.
