摘要： A heating, ventilation, and air conditioning (HVAC) system includes a working fluid reservoir having an enclosure defining a chamber configured to fluidly couple to a working fluid circuit, where the chamber is configured to receive and store working fluid from the working fluid circuit. The HVAC system also includes an actuator configured to adjust a component disposed within the enclosure to adjust a volume of the chamber and a control system configured to instruct the actuator to adjust a position of the component disposed within the enclosure to increase the volume of the chamber, to reduce the volume of the chamber, or both based on an operating mode of the HVAC system.

摘要： An air-conditioning apparatus includes a controller configured to operate in a heating normal operation mode and a heating-defrosting operation mode. In a case of switching from the heating normal operation mode to the heating-defrosting operation mode, the controller makes a selection from an initial control mode 1, in which control is performed such that an initial frequency of the compressor is set to a predetermined maximum frequency and an initial opening degree of the flow control device is set to an opening degree lower than a predetermined maximum opening degree, and an initial control mode 2, in which control is performed such that the initial opening degree of the flow control device is set to the predetermined maximum opening degree and the initial frequency of the compressor is set to a frequency lower than the predetermined maximum frequency, to execute the heating-defrosting operation mode.

摘要： An air conditioner including a distributor capable of adjusting the distribution of fluid flow to branched pipes is provided. The air conditioner includes a distributor configured to distribute a fluid flowing therethrough, and a heat exchanger including refrigerant pipes through which the fluid distributed by the distributor flows, the heat exchanger configured to heat exchange the fluid with air. The distributor includes an outer pipe having a cylindrical shape through which the fluid passes, and branched pipes. Each of the branched pipes includes one end connected to the outer pipe by being inserted into the outer pipe and includes a fluid passing part provided to allow the fluid to flow in or out. At least two branched pipes are configured such that at least one of an insertion length and a diameter of the fluid passing part inserted into the outer pipe are different from each other.
