20090134082 | Piston for a linear spool valve - A piston for a linear spool valve, the valve comprising a body having a inner surface. The body is made of a material with a relatively low heat expansion coefficient α | 05-28-2009 |
20100150723 | Rotor for a Compressor - According to the present invention there is provided a rotor ( | 06-17-2010 |
20110163175 | COMPACT HEAT PUMP USING WATER AS REFRIGERANT - According to the present invention there is provided a compact heat pump using water as refrigerant, comprising an evaporator located at a first end section of the heat pump casing, adapted to allow evaporation of water therefrom, One or more compressors located at a second end section of the heat pump casing adapted to induce said evaporation by maintaining vacuum, provided with an intake conduit extending from the evaporator to the compressor leading vapor thereto. A condenser is located in the intermediate section of the casing wherein the intake conduit passes therethrough, adapted for condensing the vapor. The heat pump also comprises vacuum means allowing creating and maintaining vacuum in the casing. There is also provided a snow dome allowing skiing and snow related activities in above zero conditions using the heat pump for creation of snow or ice slurry. | 07-07-2011 |
20130092523 | EVAPORATOR WITH COATED AND CORRUGATED TUBES - An evaporator having more efficient heat transfer tubes, that are either or both coated and vertically corrugated. The coating, though reducing the heat transfer co-efficient, lengthens the time between cleaning treatment to increase the overall efficiency of the evaporator. The corrugation of the tubes controls the film characteristics and enhances evaporation from the film upon condensation of vapor within the tubes. The corrugation profile is selected to enhance waviness and turbulence of the films and thereby increase evaporation and condensation and hence the effectivity of the evaporator. | 04-18-2013 |
