| 发明名称 | Refrigeration system with free-cooling | ||
| 摘要 | A system for cooling air for use with a liquid cooling fluid loop. The system includes a first refrigerant circuit with an air-cooled condenser, a second refrigerant circuit with a liquid-cooled condenser, and a free-cooling loop. A control device is provided for controlling the operation of the system between a first mode, a second mode, and a third mode. When operating in the first mode, only the free-cooling loop cooperates directly with liquid cooling fluid in the liquid cooling fluid loop to cool the liquid cooling fluid, when operating in the second mode, the second refrigerant circuit is not engaged, and when operating in the third mode, the free-cooling loop interacts with the second refrigerant circuit to reject heat of the second refrigerant circuit through the free-cooling loop. | ||

| 主权项 | 1. A system for cooling air for use with a liquid cooling fluid loop, the system comprising: a first refrigerant circuit with an air-cooled first condenser, all heat generated by the first refrigerant circuit is rejected through the air-cooled first condenser; a free-cooling loop with a free-cooling loop coil located upstream of the air-cooled first condenser of the first refrigerant circuit; a second refrigerant circuit with a liquid-cooled second condenser, all heat generated by the second refrigerant circuit is rejected through the free-cooling loop coil of the free-cooling loop; a control device for controlling the operation of the system between a first mode, a second mode, and a third mode; wherein when operating in the first mode, only the free-cooling loop exchanges heat directly with liquid cooling fluid in the liquid cooling fluid loop to cool the liquid cooling fluid, when operating in the second mode, the first refrigerant circuit is engaged and the second refrigerant circuit is not engaged, and when operating in the third mode, the free-cooling loop interacts with the second refrigerant circuit to reject heat of the second refrigerant circuit through the free-cooling loop. | ||
