Abstract: The present application provides a heat exchange device and a dishwasher. The heat exchange device includes an evaporator, a first liquid storage tank, a second liquid storage tank and a power unit. A medium inlet and a medium outlet are defined in the evaporator, the first liquid storage tank is in communication with the medium inlet, and the second liquid storage tank is in communication with the medium outlet and the first liquid storage tank. A liquid inlet and a gas discharge port are defined in the second liquid storage tank. The power unit is arranged between the evaporator and the first liquid storage tank, or between the evaporator and the second liquid storage tank, so as to drive a liquid medium to circularly flow between the first liquid storage tank, the evaporator and the second liquid storage tank.

Abstract: A mobile air conditioner, comprising: a first heat exchanger, having a first interface and a second interface for a refrigerant to enter and exit; a phase-change energy storage heat exchange device, including a second heat exchanger and a phase-change energy storage working medium, wherein the second heat exchanger and the phase-change energy storage working medium may exchange heat therebetween, and the second heat exchanger has a third interface and a fourth interface for the refrigerant to enter and exit; a first refrigerant pipeline, connected to the first interface and the third interface; and a second refrigerant pipeline, connected to the second interface and the fourth interface.

Abstract: An air conditioner includes a first medium circulating system including a first, second, and a fifth heat exchanging units, and a first and second throttling units. The first heat exchanging unit is serially connected between the first and second throttling units, the second throttling unit is serially connected between the first and second heat exchanging units, the first throttling unit is serially connected between the fifth heat exchanging unit and the first heat exchanging unit, and the first heat exchanging unit and the fifth heat exchanging unit are used to exchange heat with an environment. An energy storage apparatus is provided with an energy storage material. The second heat exchanging unit exchanges heat with the energy storage material. The air conditioner realizes diversified cooling ways for the environment, and includes an operation mode for synchronously cooling the room and storing the energy for the energy storage material.
