  • Patent number: 6883344
    Abstract: The invention relates to a novel structured air-conditioner with both cooling and warming functions, comprising a compressor, an out-door heat exchanger, an in-door heat exchanger and a four-way change-over valve, characterized in that it further comprises a parallel capillary device, a parallel expansion valve device or a combination of parallel capillary and expanding valve connected with the in-door and the out-door heat exchanger respectively. Said parallel capillary device, said parallel expansion valve device or the combination comprises a two-position three-way change-over valve or one-way valve with opposite direction of leading through and two groups of parallel capillary tube, two groups of parallel expanding valve, parallel capillary tube and expanding valve or a combination of two groups of series capillary tube and expansion valve.

  • Publication number: 20020175313
    Abstract: A nonazeotropic working fluid medium for use in a thermodynamic cycle system, comprising a mixture of compounds and characterized in that one or more vaporization loss/replenishment cycles of each less than about 15% of the total weight of the medium and cumulative up to about 50% of the total weight of the medium result in a total decrease in the coefficient of performance of said medium of no more than about 5%, or a loss in electric power generating efficiency of not more than about 3 percent.

  • Patent number: 5049296
    Abstract: A new kind of working medium that can be applied to Gu's thermodynamic cycle system is provided. Such a working medium can enable the curves of the evaporation heat exchange process and the condensation heat exchange process in the thermodynamic cycle system to be non-parallel in the temperature entropy diagram, that is, the isobaric phase transformation curves of such substance are not parallel with each other in the temperature entropy diagram.
