WebThe Heat Rejection Subsystem is designed to provide the waste heat rejection for the Active Ther-mal Control System of the International Space Station Alpha. The design … WebThe absorption process is exothermic (i.e., it generates heat), and heat must be rejected from the absorber to the condenser water and cooling tower loop. Because of this additional heat rejection load, absorption chillers require a larger cooling tower compared to a mechanical chiller with the same capacity. The basic absorption cycle shown in
WebThe sensible heat has to be first absorbed by the surroundings and then released into the air. The cooling load factor accounts for this time delay. The heat generated by a motor is a cooling load only if the motor is located inside the air-conditioned space or in the ducted supply air stream and it is not directly exhausted away from the source.
