摘要： System recognition is performed on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, an outdoor unit selected from among all outdoor units of a first network performs a recognition process on the outdoor units and indoor units of the first network. In the first network, communication between individual devices including the outdoor units and the indoor units is performed by using a high frequency, and the recognition process performed by the selected outdoor unit uses a recognition signal having a low frequency.

摘要： An electric control box includes a box body including a bottom plate and a box cover covering the bottom plate. The box cover include an outer box cover and an inner box cover. The inner box cover includes a water blocking member at an edge of the inner box cover. The water blocking member protrudes outward from the edge of the inner box cover toward an edge of the outer box cover. The water blocking member is configured to block water on the outer box cover from flowing into the inner box cover.

摘要： Each of a plurality of temperature adjustment apparatuses variably adjusts the amount of heat exchange between an inflow medium, which is a liquid medium supplied to a corresponding indoor heat exchanger, and an outflow medium, which is a liquid medium discharged from the corresponding indoor heat exchanger. Each of the plurality of temperature adjustment apparatuses reduces the heat exchanging capacity of the corresponding indoor heat exchanger by increasing the amount of heat exchange between the inflow medium and the outflow medium when the heat exchanging capacity of the corresponding indoor heat exchanger is larger than the indoor load. When there is no temperature adjustment apparatus in which the amount of heat exchange between the inflow medium and the outflow medium is set to the minimum, the heat source apparatus reduces the heating capacity or the cooling capacity for changing the temperature of the liquid medium.

摘要： A rotor has a shaft, a rotor core, and a position detection magnet. The rotor core is formed of electromagnetic steel sheets and has an annular shape about the shaft. The position detection magnet has an annular shape about the shaft and is attached to one side of the rotor core in an axial direction of the shaft. The position detection magnet has a first end surface facing the rotor core and a second end surface opposite to the first end surface. The position detection magnet has a tapered part at an inner periphery thereof, and the tapered part is inclined so that a distance from the shaft is maximum at the second end surface.

摘要： A ductless HVAC system solution equipped with quick-connecting connectors and a line-set pre-charged with refrigerant and method of installation thereof. The system is simplified such that an amateur may conduct the installation without professional assistance. Pre-charged refrigerant line-sets, which are designed to contain the recommended pressure of requisite refrigerant are employed. A quick-release connection system housed within quick-connect connectors ensures refrigerant does not leak from the pre-charged refrigerant piping during installation, and ensures manual refrigerant charging is not needed. The quick-connect connectors feature a double-sealing system with a unique automatic safety valve which releases the refrigerant only when the indoor and outdoor components are connected and sealed, avoiding any potential leakage.

摘要： A configuration management system for a heating, ventilation, and air conditioning (HVAC) system includes a controller having a memory storing a baseline configuration of the HVAC system. The baseline configuration of the HVAC system indicates that the HVAC system is an air conditioning system or a heat pump system. Additionally, the controller is configured to determine a current configuration of the HVAC system based on detecting whether a reversing valve is present in the HVAC system. The current configuration of the HVAC system includes an air conditioning system configuration or a heat pump system configuration. The controller is also configured to perform a control action in response to determining that the current configuration is different than the baseline configuration.
