Patent number: 6338254Abstract: An efficient method and system for dehumidifying an environment and refrigerating a second environment with a closed loop refrigeration system consisting of compressing refrigerant with a refrigeration compressor (10) to a high temperature and pressure, condensing the high pressure refrigerant to a liquid at a high temperature, circulating high pressure refrigerant through a heat exchanger (60) which is used to transfer energy from the liquid to an environment which is being air conditioned at a higher efficiency which contains the refrigerated environment (200). The liquid is then evaporated to a gas at a low pressure in a refrigeration evaporator coil (220).Type: GrantFiled: December 1, 2000Date of Patent: January 15, 2002Assignee: Altech Controls CorporationInventor: Richard H.

Patent number: 6134796Abstract: A simple easy-to-use aircraft navigational plotter is disclosed. The device is used in conjunction with the signals and readouts received from a pair of VOR (Very high frequency Omni-directional Range) stations. A pair of plotter arms is rotatably connected to a central hub (1) and each is removably attached to a center point (11), which is part of a disc (2), that is affixed to a navigation chart over the VOR stations to be used for navigation. The attachment means of the plotter arms (4) to the center point discs (2) provides for a fit where the plotter arms each may both slide and rotate about the respective center point to which each arm is attached.Type: GrantFiled: March 19, 1998Date of Patent: October 24, 2000Assignee: Altech Controls CorporationInventor: Jeffrey W. Johnson

Patent number: 6105379Abstract: The present invention discloses an automatic self-adjusting thermally powered expansion valve for controlling the flow of refrigerant to an evaporator of a refrigeration system. The valve includes a differential fluid amplifier transducer which produces a constant flow of refrigerant independent of the liquid line pressure and includes a generally cylindrical interior with an inlet chamber having an inlet port and an outlet chamber having an outlet port and an orifice between the chambers providing a passage for the flow of refrigerant through the valve. The flow of refrigerant through the valve is regulated by a valve element, which moves longitudinally within the chambers with respect to the orifice. The longitudinal position of the valve element is controlled by force generators and sensors. The position of the valve element depends on the fluid pressure and the size of the pressure disks, and the spring constant of the compression spring.Type: GrantFiled: March 14, 1997Date of Patent: August 22, 2000Assignee: Altech Controls CorporationInventors: Richard H.

Patent number: 5692387Abstract: A refrigeration system includes in a closed loop connection a compressor for compressing a refrigerant, a desuperheater for cooling the hot compressor discharge gas via the injection of liquid refrigerant, and a condenser for condensing the compressed, desuperheated refrigerant into a liquid refrigerant. The liquid refrigerant is injected into the compressed refrigerant by utilizing a liquid column for supplying pressure to the liquid refrigerant for injecting liquid refrigerant into the compressed refrigerant without using a mechanical pump. Another method of injecting the liquid refrigerant into the compressed refrigerant is to use a venturi pump at the injection point to supply the liquid refrigerant for injection into the compressed refrigerant. The desuperheater causes the temperature of the hot refrigerant vapor leaving the compressor to be reduced from a superheated condition to temperature closer to its condensing temperature prior to its entry to the condenser.Type: GrantFiled: April 28, 1995Date of Patent: December 2, 1997Assignee: Altech Controls CorporationInventors: Richard H.
