A boat includes: a propulsion device (20) configured to generate propulsion force for a vessel body from driving force from an engine; a detection unit (5) configured to detect a current position, a bow direction, and a movement speed of the vessel body; a steering device such as a steering wheel (3) configured to change a cruising direction of the vessel body; a steering sensor (52) configured to detect an operation amount of the steering device; and a control device (30) that is connected to the propulsion device, the detection unit, and the steering sensor, and is configured to acquire an operating status of the propulsion device and a detection result obtained by the detection unit and the steering sensor, and to control the propulsion device based on the detection result. The control device executes a turning operation with the propulsion device, when the operation amount of the steering device detected by the steering sensor exceeds a threshold and when the movement speed of the vessel body detected by the detection unit is not higher than a predetermined value.
The heat pump includes a terminal block box housing a terminal block for supplying an electric power to at least one electrical device. The terminal block box is supported and made rotatable in a horizontal direction by a hinge. The terminal block box is located between a portion of side plates of a package and electromagnetic valves located on the side of the portion of the side plates. As a result, maintain of electrical devices can easily be performed.
An outdoor unit of the heat pump includes a compressor, an oil separator provided in a discharge path of the compressor, an outdoor-unit connecting pipe connecting an intake path of the compressor and an outdoor unit of an another heat pump for supplying a refrigerant to the outdoor unit of the another heat pump, an oil supply pipe extending from a predetermined position of the oil separator and connecting to the outdoor-unit connecting pipe, an on-off valve provided on the oil supply pipe, an expansion valve provided in a portion of the outdoor-unit connecting pipe between a connecting part connected to the intake path and a connecting part connected to the oil supply pipe, and a refrigerant filling port provided in a portion of the outdoor-unit connecting pipe between the connecting part and the expansion valve.
A gas-side stop valve on the gas refrigerant side and a liquid-side stop valve on the liquid refrigerant side are provided in a package of an outdoor unit. A gas-side filter on the gas refrigerant side is mounted on the indoor unit side relative to the gas-side stop valve and inside the package of the outdoor unit. A liquid-side filter 9 on the liquid refrigerant side is mounted on the indoor unit side relative to the liquid-side stop valve and inside the package of the outdoor unit. As a result, it is not necessary to ensure a place for mounting the gas-side filter and the liquid-side filter at the time of installation on site and the workability can be improved.
A subcooler is made up of a plate type heat exchanger. The accumulator is located between a compressor and the subcooler in a width direction of an outdoor unit in a planar view. The subcooler overlaps with the accumulator in the width direction in the planar view. As a result, a compact heat pump can be provided when the subcooler is a plate type heat exchanger.
