Abstract: An air-conditioning apparatus includes when the compressor frequency exceeds a set frequency, perform a normal operation in which the compressor is controlled by causing the control width to be a first control width. The controller is configured to perform, when the compressor frequency is equal to or smaller than the set frequency and a rotation speed of the indoor fan exceeds a set rotation speed, a low performance operation in which the compressor is controlled by causing the control width to be a second control width, and, when the compressor frequency is equal to or smaller than the set frequency and the rotation speed of the indoor fan is equal to or smaller than the set rotation speed, a low-air-flow and low-performance operation in which the compressor is controlled by causing the control width to be a third control width.

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.

Abstract: 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.
