Abstract: Disclosed are a method, device for controlling the output of the air volume and a memory medium. The method includes: determining the temperature difference value according to the current temperature value and the preset temperature value of a cabinet; controlling the opening of an air valve of a variable air volume terminal according to the temperature difference value, so as to adjust the air volume needed by the cabinet. The temperature value needed to be adjusted is determined according to the difference value between the current temperature value and the preset temperature value. The opening of the air valve of the variable air volume terminal is correspondingly adjusted according to the temperature value needed to be adjusted, so as to adjust the air volume needed by the cabinet, and adjust the air volume according to the actual demand.

Abstract: 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.

Abstract: A refrigeration cycle apparatus includes a refrigeration cycle through which refrigerant is circulated, an indoor unit that accommodates at least a load-side heat exchanger of the refrigeration cycle and is placed indoors, and a controller that controls the indoor unit. The indoor unit includes an indoor air-blowing fan, an air inlet through which indoor air is sucked in, and an air outlet through which the air sucked in from the air inlet is blown indoors. The controller activates the indoor air-blowing fan when leakage of refrigerant is detected. An air passage that allows air to pass through the air outlet is established in the air outlet at least when leakage of refrigerant is detected.

Abstract: A system and method to control environmental parameters of predefined zones within a structure. An embodiment of the system uses damper assemblies that are entirely wireless as a result of energy capturing devices which convert air flow within the HVAC system ductwork into electrical current and a wireless control module that remove the need for hard-wiring for power or control. Still further, an embodiment of the system uses wireless components to monitor the environmental parameters of a structure's zones, process and communicate necessary zone adjustments, and actuate system components.

Abstract: An air sampling system configured to detect an air quality metric for a plurality of volumetric regions is disclosed. The system comprises an air sample return unit, an air flow controller, and at least one sensor. The air sample return unit is configured to independently transfer air from the plurality of regions as a plurality of air samples. The air flow controller is configured to receive each of the plurality of air samples and selectively direct a selected sample to a sensor supply line and the remainder of the samples to a sample purge line. The at least one sensor is configured to measure an air quality metric of the selected sample and communicate the air quality metric to a controller. The remainder of the air samples are directed to the air sample return unit throughout operation.

Abstract: An air conditioner which is able to prevent leaked refrigerant gas from disadvantageously stagnating at a part of a room space when leakage of refrigerant gas occurs in an indoor unit is provided.An air conditioner of the present invention includes an indoor unit having an upper outlet port and a lower outlet port and uses flammable refrigerant, the air conditioner including: a shutter provided at the lower outlet port and is configured to switch between a blowout capable state in which wind is blown out and a blowout incapable state in which no wind is blown out; a refrigerant gas sensor provided in the indoor unit, and a controlling unit configured to control the shutter. In a driving state in which the lower outlet port is in the blowout incapable state, when the refrigerant gas sensor detects the refrigerant gas, the controlling unit switches the lower outlet port from the blowout incapable state to the blowout capable state.
