Abstract
A capability control apparatus for a cooling system having a direct expansion type evaporator comprises a control valve mounted in a heating system for a generator for controlling an amount of heat to be given to the generator. Temperature sensors are mounted at inlet and outlet sides, respectively, of a cooling system for an absorber, and an arithmetic unit is connected to the temperature sensors and the control valve. The arithmetic unit calculates the amount of heat to be given to the generator based on signals transmitted from the temperature sensors to the unit and issues and transmits to the control valve a control signal for controlling the latter.
