Heat pump cycle device
First Claim
1. A heat pump cycle device comprising:
- a compressor for drawing and compressing refrigerant;
a first high-pressure heat exchanger located to heat a first fluid circulating in a first fluid circuit, using high-pressure refrigerant discharged from the compressor;
a second high-pressure heat exchanger located to heat a second fluid circulating in a second fluid circuit, using the high-pressure refrigerant flowing out of the first high-pressure heat exchanger;
a first heating heat exchanger located to heat a third fluid using the first fluid;
a second heating heat exchanger located to heat the third fluid using the second fluid;
a decompression unit located to decompress the high-pressure refrigerant flowing out of the second high-pressure heat exchanger; and
a low-pressure heat exchanger which is located to evaporate low-pressure refrigerant decompressed by the decompression unit.

Abstract
A heat pump cycle device includes a compressor for drawing and compressing refrigerant, a first high-pressure heat exchanger located for heating a first fluid circulating in a first fluid circuit using high-pressure refrigerant discharged from the compressor, a second high-pressure heat exchanger for heating a second fluid circulating in a second fluid circuit using the high-pressure refrigerant flowing out of the first high-pressure heat exchanger, a first heating heat exchanger located to heat a third fluid using the first fluid, a second heating heat exchanger located to heat the third fluid using the second fluid, a decompression unit located to decompress the high-pressure refrigerant flowing out of the second high-pressure heat exchanger, and a low-pressure heat exchanger for evaporating low-pressure refrigerant decompressed by the decompression unit. Because the first and second high-pressure heat exchangers are located, cycle efficiency can be improved.
