US Patent 7197886 Heat reclaim refrigeration system and method

A heat reclaim refrigeration system uses a first compressor to elevate the amount of latent heat reclaimable by the system and to reclaim this heat using heat reclaim means, such as heat reclaim coils, for practical applications, such as heating a building. In addition, the system reduces pressure required from a second compressor used for refrigeration, and energy consumed thereby, especially during cold periods of the year when a refrigerant condensing means has lower condensing requirements.
