Abstract
The device comprises at least two reactors (R1, R2) containing the same solid compound, communication circuits between these reactors, the evaporator (E), the condenser (C) and the gas collector (Co) and means are provided for successively starting the solid-gas reactions in the two reactors and for producing the openings and closings of the various communication circuits in a predetermined order to obtain a continuous production of cold.
Claims12
device for producing cold, comprising two reactors (R1, R2) which contain a solid compound capable of reacting with a gas according to an exothermic reaction, these reactors being connected to a condenser (C), a gas collector (Co) and an evaporator (E), the inside of the reactors being in a heat exchange relationship with a heat source (S), n:eans being provided for successively starting the solid-gas reactions in the two reactors and for producing the openings and closings of various communication circuits between the reactors, the condenser, the collector and the condenser, in a predetermined order to obtain a continuous production of cold, which comprises means for starting the defrosting, these means being adapted for producing the following operations:
- closing of the circuit between the two reactors (R1) and (R2), opening of the circuit between the evaporator (E) and the condenser (C) and opening of the circuit between the evaporator (E) and the gas collector (Co).
