Abstract: A system and method for heating water are provided. The system includes a first subcooler for receiving a first water flow, a second subcooler for receiving a second water flow, a first condenser in fluid communication with the first subcooler and the second subcooler for receiving water from both subcoolers, and a second condenser in fluid communication with the first condenser. The method involves receiving a flow of water, and transferring heat to the water using the system.

Abstract: A controller connectable to a plurality of energy sources, energy demands and energy transfer units is contemplated. The controller is configurable to dynamically route excess energy from different sources to different demands via the energy transfer unit(s).

Abstract: A retrofit energy exchange system including a first set of valves for connecting to a first energy transfer sub-system. The system further includes a second set of valves for connecting to a second energy transfer sub-system. In addition, the system includes an energy exchange unit configured to supply excess energy from to the first energy transfer sub-system to the second energy transfer sub-system.

Abstract: A controller can be connected to a heat transfer system including pressure and temperature sensors, an electrically controlled valve, and a compressor. The controller can be configured to control the heat transfer system according to compressor suction superheat, compressor discharge superheat, compressor suction pressure, compressor discharge pressure, and temperature of water received at a condenser to be heated by waste-heat bearing fluid in an evaporator. The controller can include a touchscreen configured to display a user control interface configured to display views based on a permissions database defining different types of users. The views can include different views having different input fields, output fields, and output graphs. The permissions database can permit input of control loop parameters by one of the different types of users and prevent input of control loop parameters by another of the different types of users.

Abstract: A compressor is connected with an evaporator, a condenser, and an electrically controlled valve for circulating a working fluid in a system for recovering waste heat to provide heated water. A controller can be configured to adjust an operating capacity of the compressor to maintain output of a condenser temperature sensor at a condenser temperature set point, except when output of a compressor discharge pressure sensor indicates that a maximum operating pressure of the compressor has been exceeded. In such case the controller reduces the operating capacity of the compressor. The controller may further be configured to shut down the compressor when the discharge pressure sensor indicates that a shutdown pressure has been exceeded.

Abstract: A condenser with subcooling is provided. The condenser comprises apparatus for collecting liquid refrigerant and increasing a velocity of the liquid refrigerant as the liquid refrigerant interfaces with at least one wall of a first pass liquid medium compartment, thereby removing heat from the liquid refrigerant, subcooling the liquid refrigerant and heating a liquid medium.

Abstract: Disclosed herein is a heat exchange apparatus. The apparatus comprises one or more double walled conduit, each having an outer conduit and an inner conduit located coaxially inside the outer conduit. The conduits define a first fluid passageway for cold water at a first temperature. A drain defines a second fluid passageway for grey water at a second temperature and is located in the drain and downstream of the grey water flowing therethrough. The grey water when flowing in the second fluid passageway effects heat transfer to the cold water flowing in the first fluid passageway across the inner and outer conduits.

Abstract: Disclosed herein is a heat exchange apparatus, which comprises a hollow blade member having a first fluid inlet and a first fluid outlet and a first fluid passageway for a first fluid that extends between the inlet and the outlet. The blade member is sized and shaped to be located in a second fluid passageway for a second fluid. The blade member is configured to enhance thermal energy transfer between the fluids as they flow along their respective passageways.

Abstract: A continuous process for reclaiming rubber, steel and fiber products from tires wherein the tires and tire material flow on conveyors throughout the various steps of the process, including the steps of shredding a flow of whole tires into pieces in a shear-type shredder, and screening the flow of tire pieces by size into a first flow containing pieces at least as large as a specified size, and a second flow containing pieces under a specified size. Reshredding and rescreening the pieces of the first flow is performed until they are smaller than the specified size. Granulating the pieces of the second flow occurs in a first granulator wherein the pieces remain in the granulator until they are reduced below a second specified size. Fiber materials are vacuumed from the flow of granulated material with an air separator after granulation and steel and steel-containing rubber pieces are removed from the flow of material via a magnetic separator after the fiber materials have been removed.
