Abstract

A refrigeration cycle apparatus has a compressor disposed via a bottom member of a housing, second elastic members, a base, and first elastic members. The compressor is disposed close to an arrangement centroid of the second elastic members.

First claim

The invention claimed is:

1. A refrigeration cycle apparatus comprising:
a housing including a bottom member;
a second plurality of elastic members disposed on the bottom member;
a base disposed on the bottom member via the second plurality of elastic members;
a first plurality of elastic members disposed on the base;
a compressor disposed on the base via the first plurality of elastic members and configured to compress a refrigerant; and
at least one of a group consisting of an economizer heat exchanger disposed on the base and a water heat exchanger disposed on the base,
wherein, when a distance between a projected position P of a centroid of the compressor on the base and a projected position on the base of a centroid of one of the first plurality of elastic members which is closest to the position P is represented by r1,
the compressor and the second plurality of elastic members are disposed such that, when a circle centered at the position P with a radius of 1.5 times r1 is drawn on the base, a projected position Q of an arrangement centroid of the second plurality of elastic members on the base is present inside the circle, excluding the case that the second plurality of elastic members are disposed to be symmetrical about the centroid of the compressor.

2. The refrigeration cycle apparatus according to claim 1 ,
wherein the compressor and the second plurality of elastic members are disposed such that, when a circle centered at the position P with a radius of r1 is drawn on the base, the projected position Q of the arrangement centroid of the second plurality of elastic members on the base is present inside the circle.

3. A refrigeration cycle apparatus comprising:
a housing including a bottom member;
a second plurality of elastic members disposed on the bottom member;
a base disposed on the bottom member via the second elastic members;
a first plurality of elastic members disposed on the base;
a compressor disposed on the base via the first plurality of elastic members and configured to compress a refrigerant; and
at least one of a group consisting of an economizer heat exchanger disposed on the base and a water heat exchanger disposed on the base,
wherein the first plurality of elastic members has an arrangement centroid different from an arrangement centroid of the second plurality of elastic members, and
wherein, when a distance between a projected position S of an arrangement centroid of the first plurality of elastic members on the base and a projected position on the base of a centroid of one of the first plurality of elastic members which is closest to the position S is represented by r2,
the first plurality of elastic members and the plurality of second elastic members are disposed such that, when a circle centered at the position S with a radius of 1.5 times r2 is drawn on the base, a projected position Q of an arrangement centroid of the second plurality of elastic members on the base is present inside the circle, excluding the case that the second plurality of elastic members are disposed to be symmetrical about the centroid of the compressor.

4. The refrigeration cycle apparatus according to claim 3 ,
wherein the first plurality of elastic members and the second plurality of elastic members are disposed such that, when a circle centered at the position S with a radius of r2 is drawn on the base, the projected position Q of the arrangement centroid of the second plurality of elastic members on the base is present inside the circle.

5. A refrigeration cycle apparatus comprising:
a housing including a bottom member;
a second plurality of elastic members disposed on the bottom member;
a base disposed on the bottom member via the second plurality of elastic member;
a first plurality of elastic members disposed on the base;
a compressor disposed on the base via the first plurality of elastic members and configured to compress a refrigerant; and
at least one of a group consisting of an economizer heat exchanger disposed on the base and a water heat exchanger disposed on the base,
wherein, when a distance between a projected position Q of an arrangement centroid of the second plurality of elastic members on the base and a projected position on the base of a centroid of one of the second plurality of elastic members which is farthest from the position Q is represented by r3,
the compressor and the second plurality of elastic members are disposed such that, when a circle centered at the position Q with a radius of 0.2 times r3 is drawn on the base, a projected position P of a centroid of the compressor on the base is present inside the circle, excluding the case that the second plurality of elastic members are disposed to be symmetrical about the centroid of the compressor.

6. A refrigeration cycle apparatus comprising:
a housing including a bottom member;
a second plurality of elastic members disposed on the bottom member;
a base disposed on the bottom member via the second plurality of elastic members;
a first elastic plurality of members disposed on the base;
a compressor disposed on the base via the first plurality of elastic members and configured to compress a refrigerant; and
at least one of a group consisting of an economizer heat exchanger disposed on the base and a water heat exchanger disposed on the base,
wherein, when a distance between a projected position Q of an arrangement centroid of the second plurality of elastic members on the base and a projected position on the base of a centroid of one of the second plurality of elastic members which is farthest from the position Q is represented by r3,
the first plurality of elastic members and the plurality of second elastic members are disposed such that, when a circle centered at the position Q with a radius of 0.2 times r3 is drawn on the base, a projected position S of an arrangement centroid of the first plurality of elastic members on the base is present inside the circle, excluding the case that the second plurality of elastic members are disposed to be symmetrical about the centroid of the compressor.
