TH41994A - Method for stopping the operation of the adsorption cooler - Google Patents

Abstract

DC60 (28/01/43) After the stop command is sent, the P2 pump for transferring solution from sorbent 2 to regenerator 3 will continue to operate. Solution transfer leads to separation of the solution from the refrigerant during the inactivity of the regenerator. The retained solution in the regenerator 3 retains the same high sorbent concentration as before the end of the operation. While the refrigerant is stored in evaporator 1 which allows the chiller to be restarted as directed.

Claims (8)

1. A method for stopping the operation of an adsorption cooler consisting of Evaporator for storing refrigerant To produce refrigerant vapors, sorbents that store the solution containing the adsorbent and adsorb the refrigerant vapor produced in the evaporator. To generate the sorption heat, the regenerator to receive the adsorbed solution and refrigerant vapor from the sorbent and heat to extract the refrigerant vapor to the concentration of the sorbent in the solution. Recovery, and a condenser for condensing the refrigerant vapor that is extracted in the regenerator, and the condensed vapor is sent to the evaporator, the assembly method includes the steps of: transferring almost the entire volume of solution from Sorbent to the regener to Responding to the stop command and then, stop the operation of the absorption chiller. 2. The method of stopping the operation of the adsorption cooler according to claim 1, where the pump is installed in the pipeline where the solution is transferred from the sorbent along the tube to the regenerator and combined. Up to the stage of: Keeping the pump running until the sorbent solution has decreased. The specified level has been reached between the full level and the empty level when the stop command was sent. 3. The method of stopping the operation of the adsorption chiller according to claim 2, including the steps of: arranging a timer, and having the pump run for a specified period of time. By such timer 4. The method of stopping the operation of the adsorption cooler according to claim 1, which includes the transfer of the refrigerant in the condensate to the evaporator. Before the adsorption cooler will Stop working completely 5. Method for stopping the operation of the adsorption cooler according to claim 4, where, in transferring the refrigerant from the condenser to the evaporator, the refrigerant is almost All were transferred 6. Method for stopping the operation of the adsorption chiller according to claim 4, which includes the procedure of: Arrangement of a pressure reducing valve in the pipeline where the substance is transferred. Cooling from the condenser to the evaporator, and when the stop command is sent, the valve is opened. Reduce the pressure wider than normal operation until the refrigerant level in the condenser drops to The level set between the full position and the empty position. 7. The method of stopping the operation of the adsorption chiller according to claim 6, that includes the procedure of: providing a second timer, and keeping the pressure reducing valve more open. Normal operation is the interval set with the second timer. 8. Method for stopping the operation of the adsorption chiller according to claim 1, where the refrigerant is Trifluoroethanol And a mixture of refrigerant and sorbent was used. As a counterpart to the cyclical working medium of adsorption cooling.
