Abstract: The present invention relates to a system in which a process of condensing steam or vapor is used for cooling or heating an ambient environment. An increase in the effectiveness of the condensing process is achieved by adjusting the input of steam or vapor into the condenser.

Abstract: The present invention provides improvement of the heat exchange process for freezing plates by achieving approximately uniform temperature on the entire surface of the device and equal heat exchange at the top and the bottom of the plate. These goals are realized when the channels with refrigerant flow are placed at an angle to the bottom side of the plate. In this case heat exchange at the top surface of the device is not limited by the size of the channels' lateral sides and even the collection of refrigerant vapor on the top of the channel takes place.

Abstract: The present invention relates to a self-governing device for a pulse feeding method of a refrigerant in refrigeration systems. Due to the difference in the refrigerant's pressure and the temperature of the refrigerant vapor in the suction line the piston is moving as a shuttle to provide a self-dosing, pulse feeding supply of the refrigerant. The self-governing device with the pulse feeding method enables the system to regulate a gas defrost process of the evaporator and increases the efficiency of the heat exchange process.

Abstract: The present invention increases the efficiency of a heat distribution system, and more specifically steam heating systems designed to maintain a constant temperature in a relatively large space by distributing the steam through pipes assembled with timers to control automatically activated valves installed on the pipes.

Abstract: The present invention provides treatment of wastewater containing oil, organic and inorganic industrial compounds, urea, and e.t.c. The resulting products will be purified water, dry fertilizer, pure carbomide, uncontaminated gas and liquid fuel, and other products that can be separated from the concentrate after ultrafiltration. In order to accomplish those and other objectives the present invention improves the system for cleaning wastewater by subjecting the wastewater to a magnetic field and heating it before the initial settling process. In addition, before ultrafiltration, the liquid is treated in an electroflotation device. The wastewater cleaning system can also be comprised of a urea separator for separating urea from other products.

Abstract: The present invention increases the efficiency of a refrigerant system by the addition of a special device that provides a constant amount of steam-generated refrigerant pressure in the condenser and is installed as a bypass to the refrigerant feed device.

Abstract: The present invention provides a solution for increasing the effectiveness of cooling and freezing processes in a heat exchange device. One of the important requirements of a heat exchange device is to keep a uniform temperature on the surface during the process. The achievement of approximately uniform temperature on the surface of the heat exchange device and on both its bottom and upper is possible with the use of a special cross-sectional form of the channels for refrigerant flow.

Abstract: The present invention relates to the art of refrigeration and more particularly to a method of regulating the cooling process by controlling the oil pressure in a compressor. The system prevents the accumulation of the liquid refrigerant in the crankcase of the compressor and allows a compressor to continue to work without interruption.

Abstract: A refrigeration unit having a jet pump with an automatically adjustable cross-section for the control of refrigerant flow that provides a more economical refrigeration process. The circulation of thermotransfering materials, such as a refrigerant, through the jet pump's evaporator facilitates a more efficient cooling effect.

Abstract: The present invention consists of a refrigeration unit with an adjusting valve that functions to control the flow of refrigerant and which is installed between the condenser and the evaporator. The adjusting valve is modulated by a controller that adjusts the refrigerant flow from the condenser to the evaporator, depending upon the outflow refrigerant vapor pressure coming from the compressor, condenser, or evaporator. Thus, substantial energy losses are avoided.
