<p><P>PROBLEM TO BE SOLVED: To effectively perform heating of a cabin when heating by using waste heat from a heat source and heat of a heating medium passing through a capacitor of a heat pump. <P>SOLUTION: When heating a vehicle cabin 5, the vehicle cabin 5 is also heated by using the heat of the heating medium passing through the capacitor 8 of a heat pump 6 in addition to heating the vehicle cabin 5 by using the waste heat from a power unit 1. At this time, air (outdoor air) is sent toward an evaporator 10 through activating an air blower 12 in order to effectively heat the vehicle cabin 5 by using the heat of the heat medium passing through the capacitor 8 of the heat pump 6, but the air may cool down the power unit 1. Considering this fact, the operation of the air blower 12 is controlled based on an overall heating performance QH which corresponds to a total value of a heating performance Qhc for the vehicle cabin 5 by using the waste heat from the power unit 1 and a heating performance Qhp for the vehicle cabin 5 by using the heat of the heating medium passing through the capacitor 8 of the heat pump 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
