Description

The present invention is related to magnetic heat pump system.

  The magnetic heat pump system (magnetic refrigeration) that uses magnetocaloric effect material as a working element is environmentally friendly because it does not use chlorofluorocarbons or alternative chlorofluorocarbons compared to conventional gas heat pump systems that use refrigeration technology that uses gas compression and expansion. . Moreover, the magnetic heat pump system does not require a compression process or an expansion process using a compressor necessary for a gas heat pump, and has high energy efficiency. The configuration required for the magnetic heat pump system is only a pump that moves the heat transport medium that passes the magnetocaloric effect material and performs heat exchange, and a magnetic field application device that applies a magnetic field change to the magnetocaloric effect material.

  Magneto-caloric effect materials used in magnetic heat pump systems have the property that the temperature changes when a magnetic field is applied. More specifically, the magnetocaloric effect material has a phenomenon (magnetocaloric effect) that becomes warm when a magnetic field is applied and cools when the magnetic field is erased.

The attached example is shown. As shown in FIG. 8B, when the number of permanent magnets 23 is large, the rotation shaft of the reciprocating pump and the rotation shaft of the magnetic heat pump main body may be connected via a speed change mechanism.

  In the first to fourth magnetic heat pump systems 51 to 54, the discharge operation is performed by combining the application and removal of the magnetic field by the permanent magnet 23 with respect to the hydraulic fluid discharged from the material container 25 by the reciprocating pump 13. The temperature of the liquid can be adjusted. Then, by combining the operation of the reciprocating pump 13 and the application and removal of the magnetic field by the permanent magnet 23, the hydraulic fluid having a low temperature is always discharged from the specific material container 25, and the temperature is always discharged from the other specific material container 25. High hydraulic fluid can be discharged. In this case, if the heat exchanger 45 through which the low-temperature hydraulic fluid passes is assembled into a cooler unit, and the heat exchanger 45 through which the high-temperature hydraulic fluid passes is combined into a heater unit, the magnetic heat pump system can be used as a vehicle. It can be applied to the air conditioning apparatus. When the magnetic heat pump system is applied to an air conditioner for a vehicle, a cooler unit is arranged upstream of the cooling passage, and a heater unit is installed in the heating passage located downstream of the air mix damper that adjusts the intake amount of the air conditioning wind.
