Patent number: 6904760Abstract: A selectively controllable valve is arranged in a refrigeration circuit which interconnects the evaporator and the condenser and is controlled so that a pressure differential is built up across the valve. The valve is selectively opened to allow “batches” of working fluid to pass therethrough. In some embodiments, the working fluid which is allowed to pass through the valve, is heated in a chamber to increase the amount of pressure on the downstream side of the valve. This produces expanded pressurized working fluid which increases the pressure in the condenser and forces previously condensed and liquefied working fluid through a flow restricting transfer device into an evaporator. Condensation of the just heated gas in the condenser subsequently reduces the pressure on the downstream side of the valve and establishes conditions suitable for the passage of a further amount of gaseous working fluid while itself becoming liquid to be forced through the flow restricting transfer device.Type: GrantFiled: March 14, 2003Date of Patent: June 14, 2005Assignee: Crystal Investments, Inc.Inventor: Otto R.

Patent number: 6101835Abstract: A water cooler is provided having a cabinet with water spigots and a door for accessing a refrigeration unit. The refrigeration unit includes a freezer compartment and may also include an icemaker. The cabinet interior contains a water reservoir which is supplied with water from a water bottle inverted in the top of the cabinet. Alternatively, the reservoir may be provided with an external source of water. In such case, an E-Coli sanitization module and a particulate water filter are provided. Cooling is effected with a compressor unit, condenser unit, an expansion valve and the refrigeration unit--all of which are interconnected with a closed loop coolant line. Predetermined segments of the coolant line are used to create freezing temperatures in the freezer compartment and non-freezing temperatures in a storage area, selected water lines and the reservoir. The condenser unit includes a condenser coil section which may be wrapped with ambient water for producing a supply of hot water.Type: GrantFiled: April 3, 1999Date of Patent: August 15, 2000Assignee: OSO TechnologiesInventors: Otto R.
