摘要:
A device for continuous production of heat and cold comprises a combination of an external heat source (10), at least first and second units (1, 2) each of which operates by using different solid-fluid adsorbent-refrigerant pairs, and each of which includes two reactors (11, 12; 21, 22) containing the same solid adsorbent, a condenser (13, 23) and an evaporator (14). The reactors of the first unit (1) are connected alternately to the external heat source (10) and the heat recovered from the first unit (1) is used to heat alternately the reactors of the second unit (2). Heat may be tapped at the condensers, and cold may be tapped at the evaporators.

A refrigerating and heating apparatus using a solid sorbent includes at least one compartmentalized reactor having solid sorbents able to fix at least one refrigerating fluid and in contact with a heat exchanger, a mechanism for the alternate circulation of a heat transfer fluid between hot and cold sources, by use of the exchanger, in order to create in the sorbent a temperature front passing through the compartments, a condenser and an evaporator. The thermal conductivity and permeability of the sorbent are lower parallel to the displacement of the heat transfer fluid in the exchanger than perpendicular thereto. Gaseous refrigerating fluid circulating means create a pressure front passing through the compartments with the temperature front.
摘要:
The invention relates to an improved thermodynamic apparatus for cooling or heating by adsorption of a refrigerating fluid on a solid adsorbent. The apparatus includes--a hot circuit adapted to heat and circulate a heating fluid;--a cold circuit adapted to cool and circulate a cooling fluid;--a cooling circuit for an enclosure to be air-conditioned;--two tanks containing a solid compound with large capacities but having a low energy of adsorption, said tanks, connected together and to the different. The two tanks comprising: at least one reactor adapted to receive said adsorbent compound, at least one condenser adapted to condense the refrigerating fluid desorbed under the effect of the action of the hot fluid passing through the adsorbent compound laden with refrigerating fluid, at least one evaporator adapted to vaporize the refrigerating fluid adsorbed on the adsorbent compound cooled by the cold circuit, such that:--the hot circuit is adapted to be connected to the reactors of the two tanks;--the cold circuit is adapted to be connected either to the condensers or to the reactors of the two tanks;--finally, the cooling circuit is adapted to be connected to the evaporators of the two tanks.
