Abstract
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.

A heat pump having an outdoor unit with a compressor, an outdoor heat exchanger, and a plurality of electrical devices including a plurality of on-off valves and a plurality of expansion valves housed in a package, the heat pump comprising:
- a terminal block box housing a terminal block for supplying an electric power to at least one of the electrical devices, wherein
- the terminal block box is located between a portion of side plates of the package and some of the plurality of electrical devices located on the side of the portion of the side plates, and
- the terminal block box is supported and made rotatable in a horizontal direction by a hinge, and when the terminal block box is located at an open position, the on-off valves of the electrical devices are exposed to the outside, and the terminal block box is located at a position higher than the plurality of expansion valves of the electrical devices.
An outdoor unit of a heat pump, the outdoor unit comprising:
- a package comprising a plurality of side plates configured to define a chamber, wherein a compressor and a heat exchanger are included in the chamber;
- a plurality of electrical devices included in the chamber, the plurality of electrical devices configured to be positioned between a first side plate of the plurality of side plates and a second side plate of the plurality of side plates, the plurality of electrical devices comprising:
- a plurality of on-off valves;
- and
- a plurality of expansion valves;
- a terminal block via which electric power is supplied to at least one of the electrical devices;
- and
- a terminal block box defining a housing in which the terminal block is located, the terminal block box is located at a position higher than the plurality of expansion valves and is configured to be rotatable in a horizontal direction between a closed position and an open position;
- wherein, when the terminal block is in the closed position, the terminal block box is configured to be positioned intermediate the first side plate and at least one of the plurality of on-off valves such that the terminal block box fills an opening and the at least one of the plurality of on-off valves is inaccessible via the opening;
- and
- wherein, when the terminal block is in the open position, the at least one of the plurality of on-off valves is accessible via the opening.
