Abstract: An air-cooling type chiller is provided. The chiller may include a plurality of fans, and an intermediate device provided between adjacent fans of the plurality of fans. When one of the fans is disabled, air is not drawn in through the disabled fan due to the intermediate device, but instead may pass through a condenser, thereby minimizing degradation in condensing efficiency. The intermediate device may be formed as an auxiliary condenser so that any air drawn in through a disabled fan passes through the auxiliary condenser, also minimizing impact on condensing efficiency.

Abstract: Provided is a cogeneration system. The system includes a chassis, a controller cooling unit, and a driver cooling unit. The chassis is provided with a generator, a driving source, a waste heat recovering unit, and a controller. The generator generates power. The driving source drives the generator and generates heat. The waste heat recovering unit recovers a waste heat of the driving source. The controller controls operations of the generator, the driving source, and the waste heat recovering unit. The controller cooling unit introduces air at one side inside the chassis, circulates the introduced air, and cools at least any one of the generator and the controller. The driver cooling unit introduces air at the other side inside the chassis, circulates the introduced air, and cools at least any one of the driving source and the waste heat recovering unit.
