2 LOW LOAD CONTROL SYSTEM FOR 2-STAGE LOW TEMPERATURE HOT WATER ABSORPTION CHILLER

摘要

A low load control system for a cold water two stage absorption chiller is disclosed. According to one aspect of the invention, the evaporator; Absorber; A first regenerator; A second player; Auxiliary absorber; Auxiliary player; And a condenser; but, the auxiliary solution pump installed in the auxiliary solution line and the auxiliary solution pump installed in the auxiliary solution line, the opening degree of the hot water control valve installed at the hot water inlet portion of the hot water line is less than or equal to the preset first degree. If the temperature of the cold water temperature sensor provided at the cold water outlet portion of the cold water line is lowered below the first temperature, the refrigerant pump is stopped. , The pump is stopped, and the rare water pump installed in the rare liquid line, the intermediate liquid pump installed in the intermediate liquid line, and the agricultural liquid pump installed in the agricultural liquid line have a preset time for keeping the temperature of the cold water temperature sensor below the first temperature When the first time or more, the low load control system of the cold water two-stage absorption chiller is stopped.
