[ I claim:] [1.]1. A refrigeration system with heat reclaim and with floating condensing pressure, said system comprising at least one first compressor for compressing low pressure refrigerant gas from at least one first evaporator to elevate said gas pressure to an operating high pressure level, a first outdoor air cool condenser connected to said first compressor for cooling said high pressure refrigerant gas to produce a cooled operating liquid refrigerant for feeding said first evaporator through a first expansion valve, a first heat exchanger one side of which is series connected between said first compressor and said first condenser and the other side of which forms a second evaporator of a heat pump system which further includes at least one second compressor for compressing low pressure refrigerant gas from said second evaporator, at least one heat reclaim condenser connected to the high pressure side of said second compressor and to said second evaporator through a second expansion valve.
