专利汇可以提供Portable utility system专利检索，专利查询，专利分析的服务。并且A portable utility system particularly useful for drastically cooling seawater and/or forming an ice/brine slurry for application to fish. A tube-in-tube evaporator is provided for cooling the seawater while it is drawn into the evaporator by means of a positive displacement brine pump. Seawater is drawn into a tube-in-tube condenser by a coolant pump to remove heat from the system refrigerant and is continuously discharged after it is passed through the condenser coils. A compressor is provided to raise the pressure and temperature of the gaseous refrigerant. A reversible valve enables the flow of refrigerant through the system to be reversed, producing hot water at the output of the evaporator, when desired. The evaporator is formed of a first tube for conveying refrigerant and a second tube positioned in heat exchange relation within the first tube, the second tube conveying seawater to be refrigerated. The condenser may also be formed of a tube within a tube wherein the refrigerant is conveyed in the inner tube and the cooling seawater is conveyed in the outer tube. An in-line dispenser for bacteriostatic agents, or the like, can be provided. The system can supply electrical as well as hydraulic needs and can be used onshore with air cooling in place of water cooling.，下面是Portable utility system专利的具体信息内容。

权利要求

1. A portable single drive, positive displacement utility system for converting seawater into refrigerated seawater, comprising: single drive means; an evaporator for lowering the temperature of seawater, said evaporator comprising an outer coiled evaporator tube and an inner coiled evaporator tube within and coextensive with said outer evaporator tube and having a discharge end extending therefrom; a refrigerant condenser comprising an outer coiled condenser tube and an inner coiled condenser tube within and coextensive with said outer condenser tube and having a discharge end extending therefrom; refrigerant tUbe means for connecting said outer evaporater and condensure tubes constituting with said outer tubes a refrigerant line; strainer means in said refrigerant line; compressor means connected to said refrigerant line for circulating refrigerant therethrough and driven by said single drive means; means for pumping seawater through said inner evaporator and condenser tubes comprising at least one positive displacement pump, and strainer means therefor, connected to said inner evaporator and condenser tubes and driven by said single drive means, whereby to provide cooled seawater discharge from said inner evaporator tube discharge end and heated seawater discharge from said inner condenser tube discharge end; valve means for reversing the flow of refrigerant through said refrigerant line whereby to produce hot water at the discharge end of said inner evaporator tube.

2. A system in accordance with claim 1 wherein said condenser and evaporator coils are nested.

3. A system in accordance with claim 1 and further comprising means for recirculating said refrigerated seawater at the output of said refrigerator through said pump means to form the output of said inner evaporator tube as an ice/brine slurry.

4. A system in accordance with claim 1 and further comprising means for applying fish treating agents to said pump upstream of said evaporator.
