| 20090120619 | METHOD FOR EXCHANGING HEAT IN VAPOR COMPRESSION HEAT TRANSFER SYSTEMS - The present disclosure relates to a method for exchanging heat in a vapor compression heat transfer system. In particular, it relates to use of an intermediate heat exchanger to improve performance of a vapor compression heat transfer system utilizing a working fluid comprising at least one fluoroolefin. In addition, the present disclosure relates to a vapor compression heat transfer system comprising an intermediate heat exchanger in combination with a dual-row evaporator or a dual-row condenser, or both. | 05-14-2009 |
| 20090139575 | Method and system for supplying water to cooling towers - The present invention relates to a method and a system for controlling the circulation of water films on the exchange walls of an exchange surface of a cooling tower. It comprises combining a tank and a dispenser lip to ensure that the film has a specific thickness and that it adheres to the exchange wall right from the moment it starts to flow and repeatedly so, on each exchange wall. The exchange walls between air and water are horizontally sloping at a small angle, thereby ensuring that the water flows by force of gravity and, at the same time, limiting the speed increase on the plate to avoid the droplets from being pulled away by the airflow. The water films are recovered in recovery troughs perpendicular to the flow of the water films on the plates. These troughs are tilted horizontally, and enable the recovery of the water films without being crossed by the air flows. The air is blown in by nozzles which are interposed between the water flow plates in such a way that the airflow is in a counter-current flow or, if necessary, in a cross-current flow, relative to the water films thus enabling the evaporation of the water that cools the water flow on the exchange plates without forming liquid aerosols. | 06-04-2009 |
| 20100012302 | DUAL ROW HEAT EXCHANGER AND AUTOMOBILE BUMPER INCORPORATING THE SAME - A heat exchanger has a cross-current/counter-current structure, so that air which is directed across the heat exchanger is heated in the two successive rows. This design takes advantage of the temperature glide of a refrigerant blend. In this design, the hottest refrigerant blend is in contact with the hottest air, and the coldest refrigerant blend is in contact with the coldest air, leading to a lower difference between the average refrigerant blend temperature and the average air temperature compared to a pure refrigerant in a one-row heat exchanger. | 01-21-2010 |

In accordance with the invention, the method consists in projecting a refrigerant medium into the cooling section ( | 09-02-2010 |
| 20100293995 | Cooling System of a Psychrometric Mixture by Coupling a Condensation Unit and an Evaporation Unit - A cooling system of a first psychrometric mixture having a condensation unit capable of condensing fluid contained in this mixture by direct contact with liquid comprising this fluid, the liquid being in the condensation unit at a temperature below that of the first mixture, and an evaporation unit capable of evaporating liquid in a second psychrometric mixture having fluid, the liquid being in the evaporation unit at a temperature greater than that of the second mixture, the condensation and evaporation units being coupled by a circulation circuit of the liquid, and a regulator for regulating the liquid flow. | 11-25-2010 |
| 20110290447 | METHOD FOR EXCHANGING HEAT IN VAPOR COMPRESSION HEAT TRANSFER SYSTEMS - A multi-step method is disclosed for exchanging heat in a vapor compression heat transfer system having a working fluid circulating therethrough. The method includes the step of circulating a working fluid comprising a fluoroolefin to an inlet of a first tube of an internal heat exchanger, through the internal heat exchanger and to an outlet thereof. Also disclosed are vapor compression heat transfer systems for exchanging heat. The systems include an evaporator, a compressor, a dual-row condenser and an intermediate heat exchanger having a first tube and a second tube. A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes. | 12-01-2011 |
