    Abstract: Standalone and self-contained cooling systems using compressed liquid and/or gas CO2 containers positioned in an insulated or non-insulated vessel encompassing a container which is either vertically positioned in an upright or an upside-down position. The liquid and/or gas CO2 coolant is then released into a capillary system or flow metering system to allow the CO2 to enter a second body to where the CO2 coolant properties may be leveraged. The second body includes, by way of example, a plate, a cushion, a spot treatment pad for a person's muscle, or a cooler. The temperature is controlled by a metering CO2 releasing system encompassing an electronic control device which sends alerts when pre-defined thresholds are exceeded.

Further, a passage cross-sectional area of the refrigerant inlet is configured to be smaller than a twelve-fold value of a passage cross-sectional size of the refrigerant outlet, such that a swirl speed of the refrigerant in the swirl space is increased so as to enable a decompression boiling of the refrigerant around the swirl center line.

    Abstract: A mixing portion that mixes an injection refrigerant and a suction refrigerant is formed in a range of an internal space of a heating-side body portion of a heating-side ejector from a refrigerant injection port of a heating-side nozzle portion to an inlet of a heating-side diffuser. Further, the mixing portion is formed in a shape that gradually decreases a refrigerant passage area toward a downstream side of a refrigerant flow, and a refrigerant passage area of the inlet of the heating-side diffuser is set smaller than that of the refrigerant injection port. Thus, the flow velocity of the mixed refrigerant is decelerated to a value lower than a two phase sound velocity within the mixing portion, thereby suppressing occurrence of shock wave in the heating-side diffuser and stabilizing the pressure increasing performance in the heating-side diffuser.

  • Patent number: 8353169
    Abstract: A supersonic cooling system operates by pumping liquid. Because the supersonic cooling system pumps liquid, the compression system does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

  • Patent number: 7971449
    Abstract: Heat-activated heat-pump systems and related methods are disclosed that include a power cycle coupled to a vapor-compression refrigeration cycle both utilizing the same working fluid. The power cycle comprises a boiler, an expander receiving superheated vapor and producing work from the superheated vapor, a condenser, and a pump. A regenerator conducts a first stream of working fluid from the pump to the boiler and a second stream of the working fluid from the expander to the condenser while transferring heat from the second stream to the first stream. The refrigeration cycle comprises a compressor that compresses the working fluid from the evaporator and delivers the compressed working fluid to a condenser. The expander and compressor are coupled together such that at least a portion of the work produced by the expander is utilized for running the compressor.

  • Patent number: 7870758
    Abstract: In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a control unit controls an air blowing amount of an evaporator fan so that a flow speed of refrigerant flowing in an evaporator becomes in a predetermined flow speed range. Therefore, it can prevent a large amount of lubrication oil from staying in the evaporator, and thereby the lubrication oil can sufficiently returns to a compressor. For example, the control unit includes a determining means for determining the predetermined flow speed range based on at least one of an atmosphere temperature of a condenser, a temperature of air supplied to the evaporator and a flow amount of refrigerant discharged from the compressor.
