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 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 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: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. During the period in which the organ is preserved and/or maintained, the organ may be additionally be perfused to obtain data regarding the fluid and/or organ. The data may then be used to ultimately provide information regarding the perfusion efficacy and allow for altering of the perfusion parameters.

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: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The apparatus and methods include the organ cassette with one or more openings configured to allow tubing to pass through the openings and be connected to the organ or tissue within the cassette, and including a pressure control device to allow pressure inside the portable housing to be varied.

Abstract: A cannula connects an organ with a perfusion system that monitors, treats, sustains and/or restores the viability of the organ and/or that transports and/or stores the organ. At least part of a cannula may be made of a soft elastomer to help avoid damage to the organ. In embodiments, the cannula includes a top portion, a bottom portion, a sealing ring and two compression straps. In embodiments, the cannula includes a top portion and a flexible bottom portion that may be attached to the top portion. In embodiments, part of the cannula is inserted directly into an artery and a suture is used to tie the artery in place. Also, the cannula may include an attachment feature that can be used to connect the cannula to an organ platform or chair. Various features of the cannula may allow a visual check for and venting of air bubbles in the cannula.

Abstract: The invention is targeted at the process of separating gas, such as air, from a liquid path. Specifically, the invention provides a means to remove gas from a dynamic liquid path, manage the removed gas and liquid path. The invention provides a means to remove gas from a dynamic liquid path using the buoyant property of gas in a less buoyant liquid, having ingress and egress ports for liquid and gas flow, and separate points of egress for liquid and trapped gas and integral liquid channels.

Abstract: A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.

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: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures.
