摘要： A device for pumping an absorbent solution from the low pressure side of an absorption heat exchange system to the high pressure side of that system without relying on pressure from the low pressure side. The device preferably includes a diaphragm pump disposed in an absorbent fluid pathway to pull absorbent solution from the low pressure side and to push absorbent solution into the high pressure side. The diaphragm of the diaphragm pump is powered by a piston-driven hydraulic pump which pushes and pulls oil into and out of the diaphragm pump. The hydraulic pump preferably has sufficient power to pull absorbent solution from the low pressure side of the heat exchange system without relying on any pressure from the low side. Check valves are used to permit the one-way flow of absorbent solution from the low pressure side to the high pressure side of the system.

摘要： A cooling or heating device in an absorption heat pump of GAX type, including a generator, a GAX heat exchanger, an absorber, a condenser, an evaporator, a pump connected to the absorber and generator, and a first circuit for refrigerant solution circulating through the device and connecting together at least the generator, GAX heat exchanger, absorber, condenser, evaporator, and pump. A valve device modifies the first circuit to vary the manner in which the absorber, condenser, and evaporator are connected together. At least first and second heat exchanger units enable at least one phase of the circulating solution to be changed and to enable thermal energy to be exchanged against an external fluid, the first and second heat exchanger units each including at least two mutually separate sub-heat exchangers configured to function either as an evaporator or as an absorber and condenser, depending on an operating mode of the device.

摘要： An absorption heat pump including a generator or desorber which generates vapour from a first fluid fed to a first condenser, an evaporator provided downstream of the condenser, an outlet of the evaporator connected by a third line to an inlet of a mixer of a low pressure absorber connected to a suction side of a pump feeding solution to the generator. The generator having a poor solution outlet connected by a sixth line provided with at least one lamination valve to a poor solution inlet feeding the absorber. The second line is brought into heat exchange contact with the low pressure absorber and opens into a liquid/vapour separator feeding the evaporator via a third line, the vapour outlet of the separator opening into an intermediate pressure absorber unit.
