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.

摘要： A ductless HVAC system solution is described. The system is configured for easy installation by an amateur, and therefore does not require a license, expensive tools, or much time to install. The system is equipped with pre-charged refrigerant piping, which are designed to contain the recommended pressure of requisite refrigerant. A quick-release valve system ensures refrigerant does not leak from the pre-charged refrigerant piping during installation by an amateur. The system may be controlled manually or remotely via WiFi.

摘要： A power conversion apparatus includes a rectifier to rectify a voltage of an input alternating current (AC) power source and a voltage drop device to output a dropped voltage using the voltage from the rectifier, and the voltage drop device includes a transformer and a communication voltage output device provided at a secondary side of the transformer to output a first direct current (DC) voltage for operation of a communication device. The communication voltage output device includes a first resistor provided at the secondary side of the transformer to reduce an output change rate of the first DC voltage and first and second zener diodes connected between the first resistor and ground to limit an upper limit of the first DC voltage. Accordingly, it is possible to stably supply a voltage to a communication unit while reducing standby power.
