摘要： A system that includes a heating, ventilation, and air conditioning (HVAC) system that includes a sensor system within the HVAC system. The refrigerant sensor system includes a refrigerant sensor that detects the presence of an amount of refrigerant in the HVAC system and a control system that receives the amount of refrigerant detected from the refrigerant sensor. The control system also determines the amount of refrigerant exceeds a threshold value. Additionally, the control system sends one or more output signals to one or more components that are configured to couple to one or more devices that are part of the HVAC system. The one or more components are configured to cause the one or more devices to adjust operations based on the state of the components. The sensor system also includes a housing that encloses the refrigerant sensor and control system.

摘要： Systems/methods for intelligent commissioning of an HVAC system provide a control node and at least a first network node coupled to communicate with the control node, the first network node configured to retrieve via a user interface objects configured at the control node, configure at least a second network node using the retrieved objects, and report the configuration of the second network node at the control node. A user interface of a first network node can access the objects at the control node. The first network node can apply the accessed objects to configure a second network node using a commissioning tool. The commissioning tool can be activated specifically for certain authorized HVAC personas or roles. The first network node can report the configuring at the control node. The commissioning tool can be voice-enabled to allow a single user to configure the HVAC system via voice commands.

摘要： An outdoor unit of an air-conditioning apparatus includes a compressor, a heat exchanger, and a controller. The controller includes a compressor driving circuit configured to drive the compressor, a harmonic suppressing unit configured to suppress harmonics in the compressor driving circuit, and a housing containing the compressor driving circuit and the harmonic suppressing unit. The housing has a first section having ventilation holes that allow communication between the outside and the inside, and a second section constituting a frame outside the first section. The first section contains the harmonic suppressing unit and a fan configured to blow air from inside the first section to the outside through the ventilation holes. The second section contains the compressor driving circuit.

摘要： An HVAC system includes a blower, a variable-speed compressor, an indoor air temperature sensor that measures an indoor air temperature (IAT) of an enclosed space, and a controller. The controller stores an indoor temperature setpoint and a default discharge air temperature setpoint. The controller receives the IAT. The controller determines that the IAT is not within a threshold range of the indoor temperature setpoint. The controller then determines an adaptive discharge air temperature setpoint. The controller determines a compressor speed at which to operate the variable-speed compressor based on the adaptive discharge air temperature setpoint. The controller causes the variable-speed compressor to operate at the determined compressor speed.

摘要： A method for conditioning air in a temperature-insulated test space of a test chamber and a test chamber serving for receiving test material, in which a temperature ranging from −20° C. to +180° C. is generated within the test space. A cooling cycle has an internal heat exchanger, which is connected on a high-pressure side of the cooling cycle downstream of a gas cooler and upstream of an expansion valve, the internal heat exchanger being coupled with a medium-pressure bypass of the cooling cycle, the medium-pressure bypass being connected downstream of the internal heat exchanger or the gas cooler and upstream of the expansion valve on the high-pressure side as well as upstream of a high-pressure compressor and downstream of a low-pressure compressor on a medium-pressure side of the cooling cycle, refrigerant being dosed in the medium-pressure side from the high-pressure side via the internal heat exchanger by a second expansion valve.
