The invention discloses an adsorption type refrigeration system comprising a refrigeration box, a first water tank, a second water tank and a third water tank. The refrigeration box comprises a box body used for containing a refrigerant, an adsorption bed, a condenser and an evaporator. The adsorption bed is arranged on one side in the box body. The condenser and the evaporator are arranged on the other side in the box body. The condenser is arranged on the upper portion of the box body. The first water tank is used for providing hot water for the adsorption bed. The second water tank is used for providing cold water for the adsorption bed and the condenser. The third water tank communicates with the evaporator and is used for providing a low temperature for the outside world. The evaporation and condensation processes of the refrigerant are both conducted in the box body, the transfer work of the refrigerant between the three parts, namely, the adsorption bed, the condenser and the evaporator without pipeline connection, and therefore good gas tightness is achieved; and meanwhile the structure of the system is simplified, and the machining and manufacturing cost is reduced.
