  • Patent number: 9879899
    Abstract: Surged heat pump systems, devices, and methods are disclosed having refrigerant phase separators that generate at least one surge of vapor phase refrigerant into the inlet of an evaporator during an on cycle of the compressor. This surge of vapor phase refrigerant, having a higher temperature than the liquid phase refrigerant, increases the temperature of the evaporator inlet, thus reducing frost build up in relation to conventional refrigeration systems lacking a surged input of vapor phase refrigerant to the evaporator. The temperature of the vapor phase refrigerant is raised in relation to the liquid phase with heat from the liquid by the phase separation, not by the introduction of energy from another source. The surged heat pump systems may operate in highest heat transfer efficiency mode and/or in one or more higher temperature modes.

  • Patent number: 9873826
    Abstract: This chemical heat pump includes two reaction sections R1 and R2 containing a thermal storage medium; an evaporation-condensation section D containing water or steam; and two fluid channels individually disposed so as to correspond to the reaction sections. A “first state in which R1 is set to a heat-storing state and R2 is set to a heat-release state” and a “second state in which R1 is set to a heat-release state and R2 is set to a heat-storing state” are alternately applied every time after a first period elapses. For each reaction section, in the heat-release state, a fluid is caused to flow from a first side to a second side of the corresponding fluid channel over a first period; and, in the heat-storing state, a fluid is caused to flow from the second side to the first side of the corresponding fluid channel over a second period.

  • Patent number: 9874390
    Abstract: A refrigerator is provided that includes a low energy refrigerator heat source. The refrigerator includes a heat source positioned at a source of latent heat. The heat source harvested heat from the source of latent heat and stores said heat in a fluid within that heat reservoir or heat exchanger. The warmed fluid is then supplied via a fluid pathway to an application requiring a heat output. Thus, the heat reservoir provides heat to the application without use of an energy-consuming device, which reduces the energy consumption of the refrigerator.

  • Patent number: 9863676
    Abstract: When, according to the invention, the air in the so-called Zone 2 areas is ventilated, i.e. sucked out, the ATEX Directive concerning treatment of inflammable coolants may be satisfied in an effective manner. In practice, the suction around the engine (6) of the vehicle and the ventilation of the service equipment (9, 21, 53), respectively, may ensure that the requirements in the ATEX Directive with respect to Zone 2 areas may be satisfied, if possibly inflammable vapors are discharged, since these areas are ventilated to the atmosphere. The use of the method is service-friendly when servicing air conditioning systems and when adding coolant online.
