Patent ID: 7197886

Claim:
A refrigeration heat reclaim system including at least one evaporator for evaporating a refrigerant from a refrigerant liquid into a refrigerant vapor, thereby providing refrigeration during a refrigeration cycle, said system comprising: a first compressor engageable in a heat reclaim cycle, said first compressor being operatively connected to the evaporator for receiving the refrigerant vapor therefrom and, during said heat reclaim cycle, compressing the refrigerant vapor received to a first pressure level, the refrigerant vapor being discharged from said first compressor through a first discharge outlet line connected thereto; a second compressor engageable in the refrigeration cycle, said second compressor being operatively connected to the evaporator for receiving the refrigerant vapor therefrom and for compressing the refrigerant vapor received to a second pressure level, the refrigerant vapor being discharged from said second compressor through a second discharge outlet line connected thereto for subsequent condensing into the refrigerant liquid; and a heat reclaim means having at least one heat reclaim inlet line operatively connected to said first discharge outlet line for absorbing latent heat from the refrigerant vapor discharged therein during said heat reclaim cycle, thereby reclaiming said latent heat, wherein said first pressure level is greater than said second pressure level, the refrigerant vapor at said first pressure level having an increased evaporating temperature for increasing said latent heat reclaimable therefrom by said heat reclaim means.
