| 20090158757 | System and method for controlling the cooling of variable heat loads in heat generating devices - The present invention offers an improvement over prior art cooling systems by accounting for rapid changes in thermal load.

After condensing in the condenser, the working fluid divided into two streams. One stream returns to the reservoir and the other one flows into the cooling evaporator of refrigeration cycle to produce chilled water about 12° C. When the liquid refrigerant is completely evaporated in the evaporator, the self-operated pressure regulator valve opens and the working fluid flows into the evaporator from the reservoir. A certain quality of the working fluid is closed in the evaporator, preparing for a new work cycle as above-mentioned. The system of the present invention can use organic fluid as the working fluid to utilize the low-temperature heat sources range from 60 to 200° C., using groundwater, river (sea) water or air as cold source and using gravity to transport liquid working fluid. | 01-28-2016 |
| 20160102894 | Method and Control Device for Optimizing Cooling of a High Voltage Accumulator by Means of an Air-Conditioning System - A control device, and a method for operating the control device, optimizes cooling of a high-voltage accumulator using an air-conditioning system in a vehicle. A coolant flow which is insufficient is detected by an evaporator for the high-voltage accumulator and, as a result, heat losses inside a condenser of the air-conditioning system are reduced for increasing the flow of the coolant. | 04-14-2016 |
