Abstract
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.
Claims19
A heat pump comprising:
- an outdoor unit which includes and houses:
- a receiver;
- a subcooler provided in a liquid refrigerant path of a refrigerant flow downstream of the receiver;
- an accumulator provided in an intake path of a compressor;
- and
- an oil separator provided in a discharge path of the compressor,
- wherein:
- the subcooler comprises a plate type heat exchanger,
- two members of a group comprising:
- the receiver, the accumulator, the oil separator, and the subcooler are arranged on a straight line inclined to a first side in a width direction of the outdoor unit with respect to a depth direction of the outdoor unit in a planar view,
- a remaining two members of the group comprising:
- the receiver, the accumulator, the oil separator, and the subcooler are arranged on a straight line inclined to a second side in the width direction of the outdoor unit with respect to the depth direction of the outdoor unit in the planar view, and
- the two members on the straight line inclined to the first side are adjacent to the remaining two members in the planar view.
