A chemical heat pump includes a reactor part (1) that contains an active substance and an evaporator/condenser part (3) that contains that portion of volatile liquid that exists in a condensed state and can be absorbed by the active substance. A channel (4) interconnects the reactor part and the evaporator/condenser part, In at least the reactor part a matrix (13) is provided for the active substance so that the active substance both in its solid state and its liquid state or its solution phase is held or carried by or bonded to the matrix. The matrix is advantageously an inert material such as aluminium oxide and has pores, which are permeable for the volatile liquid and in which the active substance is located. In particular, a material can be used that has a surface or surfaces, at which the active substance can be bonded in the liquid state thereof. For example, the matrix can be a material comprising separate particles such as a powder or a compressed fibre material.

Chemical heat pump working with a hybrid substance

A chemical heat pump includes a reactor part (1) that contains an active substance and an evaporator/condenser part (3) that contains that portion of volatile liquid that exists in a condensed state and can be absorbed by the active substance. A channel (4) interconnects the reactor part and the evaporator/condenser part. To heat the reactor part, a portion of this wall is arranged as a solar energy collector, which can result in a very compact structure. In at least the reactor part a matrix (13) is provided for the active substance so that the active substance both in its solid state and its liquid state or its solution phase is held or carried by or bonded to the matrix. The matrix is advantageously an inert material such as aluminium oxide and has pores, which are permeable for the volatile liquid and in which the active substance is located. In particular, a material can be used that has a surface or surfaces, at which the active substance can be bonded in its liquid state thereof. For example, the matrix can be a material comprising separate particles such as a powder or a compressed fibre material.

Thermal solar energy collector for producing heat and/or cooling

An installation for storing and/or transporting energy comprises a charging station, a discharging station and a reactor part (1). The reactor part is designed to be part of a chemical heat pump and contains an active substance. It is also arranged to be capable of being connected to the charging station for charging, i.e. transfer of the active substance to a charged state, and to the discharging station for discharging, i.e. transfer of the active substance to a discharged state. In the reactor part a matrix for the active substance can in one embodiment be provided, so that the active substance both in its solid and its liquid state is held or carried or bonded by the matrix. The matrix is advantageously an inert material such as aluminium oxide and has pores, which are permeable for the volatile liquid and in which the active substance is located. In particular, a material can be used that has a surface or surfaces, at which the active substance can be bonded in the liquid state thereof. For example, the matrix can be a material comprising separate particles such as a powder or a compressed fibre material. The installation can also be used for production of the volatile liquid in a purified form.

Storing/transporting energy

PROBLEM TO BE SOLVED: To provide a chemical heat pump which is efficiently operated according to hybrid principle and is provided by combining advantage of a solid system with advantage of hybrid system.SOLUTION: A chemical heat pump includes a reactor part 1 containing an active substance and a vaporizer/condenser part 3 containing a part which exists in such a state that volatile liquid is condensed and can be absorbed by the active substance. (The chemical heat pump operated by a solid substance has extremely low thermal conductivity, therefore, has disadvantage regarding low output or efficiency and, on the other hand, has advantages such as ability of working without movable components, high maintenance capacity and constant reaction pressure. The disadvantage of the solid substance is made up for by the hybrid substance.

Chemical heat pump operated with hybrid substance

The invention provides an air conditioner system utilizing waste heat of exhausted gas of a power plant for refrigeration. Steam in steam exhaust pipelines of a back pressure turbine, a high-pressureoxygen extractor and a boiler intermission-draining flash box is mixed and then enters a lithium bromide refrigerating unit, cold water after refrigeration enters the air conditioner system after being pressurized through a cold water pump, a circulating water pump utilizes original circulating water to cool the lithium bromide refrigerating unit and utilizes an original coiling water tower to cool the circulating water, and after the cold water is lost, a water replenishment pump drives salt removal water in a salt removal water tank into the cold water through a salt removal water pipe. A cold water system and a circulating water system are provided with safety valves correspondingly, when the pressure reaches an action value, the safety valves act, steam condensate water related by thetechnological process returns to a low-level water tank, by using the air conditioner system utilizing the waste heat of the exhausted gas of the power plant for refrigeration, the waste heat of the exhausted gas of a high-pressure deoxidant, the exhausted steam of the back pressure turbine and the exhausted gas of the boiler intermission-draining expansion device is recycled, and the safety production rate is further increased.
