The absorption heat pump includes a generator, a first condenser, a first evaporator and an absorber connected in series. A first refrigerant is cooled by the first condenser and releases a first heat capacity, evaporated in the first evaporator and receives a second heat capacity, and mixed with a sorbent in the absorber and releases a third heat capacity. The compression chiller includes a compressor, a condensing module and a second evaporator connected in series. A second refrigerant is cooled by the condensing module and releases the second heat capacity, and evaporated in the second evaporator and receives a fourth heat capacity, wherein the condensing module is connected to the first evaporator, so that the second heat capacity released by the second refrigerant is transmitted to the first refrigerant in the first evaporator. | 01-15-2015 |
20150354867 | HVAC ROOF CURB RETROFIT - A ventilation adapter unit or roof curb retrofit is provided for reducing energy costs in operating a building ventilation system. The unit is disposed between a traditional HVAC unit and a surface of the building, and has a plurality of internal passageways including a return air passageway, a discharge air passageway, and a supplemental discharge air passageway. Air entering the discharge air passageway from the HVAC unit is selectively routed into the supplemental discharge air passageway, where it is cooled by a cooling panel according to the position of a damper in the discharge air passageway. The cooling panel receives chilled fluid from a chiller, such as an ice storage system that operates a refrigeration unit during off-peak hours. Regardless of whether the air is routed through or around the damper, the air is then discharged from the retrofit unit and into the building. | 12-10-2015 |
