The double working medium combined cycle heat pump device is characterized in that a newly-added double-energy compressor (E) is added to replace a low-temperature compressor (A), a newly-added spray pipe (F) is added to replace a low-temperature throttle valve (B) in any one of the double working medium combined cycle heat pump devices of claims 1 to 8, and the double working medium combined cycle heat pump device is formed.
