The present disclosure relates to an outdoor unit for an air conditioner. The present invention relates to an outdoor unit of a gas heat pump system. An outdoor unit of a gas heat pump system according to an embodiment of the present invention comprises: a storage tank which is disposed at a suction side of a compressor and stores a refrigerant to be supplied to the compressor; and a heat exchanger for performing heat exchange of a refrigerant flowing through a refrigerant pipe or cooling water flowing through a cooling water pipe, wherein the heat exchanger is supported by the storage tank. Therefore, the outdoor unit does not require a separate frame structure for installing the heat exchanger.

A heat pump system includes a first heat pump and a second heat pump. The first heat pump includes a first outdoor unit. The first outdoor unit includes a compressor, an outdoor-unit connecting pipe, and a refrigerant filling port. The outdoor-unit connecting pipe connects an intake path of the compressor and a second outdoor unit of the second heat pump for supplying a refrigerant to the second outdoor unit of the second heat pump. The refrigerant filling port is provided in a portion of the outdoor-unit connecting pipe.

A molded equipment pad having a top deck, side walls, underlying reinforcing radial ribs, and underlying reinforcing arc-shaped ribs. The arc-shaped ribs may include a series of concentric arc-shaped ribs that are centered on the center of the equipment pad and that extend toward the side walls of the pad and a number of distributed circular hubs. Alternatively, the arc-shaped ribs may include a series of concentric arc-shaped ribs that are centered on the center of the equipment pad that end short of the side walls, a series of opposing arc-shaped ribs that are centered on the corners of the equipment pad, and a number of distributed circular hubs.

An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a compressor system configured to direct a working fluid along a working fluid circuit of the heat pump. The compressor system includes a first compressor configured to direct the working fluid along a first portion of the working fluid circuit having a first expansion device to operate the heat pump in a cooling mode and includes a second compressor configured to direct the working fluid along a second portion of the working fluid circuit having a second expansion device to operate the heat pump in a heating mode. The heat pump also includes a controller communicatively coupled to the first compressor and the second compressor, where the controller is configured to operate the first compressor and suspend operation of the second compressor in the cooling mode and to operate the second compressor and suspend operation of the first compressor in the heating mode.
