Abstract

A refrigeration cycle apparatus has a compressor disposed via a bottom member of a housing, a second elastic member, a base, and a first elastic member. A first electric component that drives a motor for the compressor and a second electric component that performs another control are fixed to the base and disposed. The base has an upper surface that contacts the first elastic member and a lower surface that contacts the second elastic member. The first electric component and the second electric component are fixed to the upper surface directly or indirectly via a substrate and/or an electric-component casing. Top portions of the first electric component and the second electric component are lower than a top portion of the compressor.

First claim

a second elastic member disposed on the bottom member;
a base disposed on the bottom member via the second elastic member;
a refrigeration-cycle constituent component fixed to the base and the refrigeration-cycle constituent component being one of an accumulator an economizer heat exchanger, a water heat exchanger, a check valve and a four way switching valve or a combination thereof;
a first elastic member disposed on the base;
a compressor disposed in the machine chamber of the housing on the base via the first elastic member and configured to compress a refrigerant;
a first electric component fixed to the base and configured to drive a motor for the compressor; and
a second electric component fixed to the base and configured to perform control that differs from control performed by the first electric component, wherein
the base has an upper surface that contacts the first elastic member and a lower surface that contacts the second elastic member,
the first electric component and the second electric component are fixed to the upper surface directly or indirectly via a substrate and/or an electric-component casing, and
top portions of the first electric component and the second electric component are lower than a top portion of the compressor.

2. The refrigeration cycle apparatus according to claim 1 , further comprising:
an expansion valve,
