摘要： A viscous heater (9) for heating cooling water for cooling a water cooled engine (E) is provided in a cooling water circuit between the engine and a front heater core (15). Even if a viscous switch (73) is turned on by a viscous ECU (200) to heat a passenger compartment using the viscous heater, a viscous clutch (7) is not immediately turned on when the engine is idling. That is, after a delay control time elapses after increasing an idling rotational speed of the engine to a target rotational speed, the viscous heater is turned on. The target rotational speed which is higher than a normal idling rotational speed is set in such a manner that the higher the cooling water temperature is, the lower the target rotational speed becomes. Thus, even if a large load is applied to the engine by operating the viscous heater when the engine is idling, it can improve fuel economy and prevent an engine stall.

摘要： A refrigeration cycle is switched from a refrigeration cycle circuit to a hot gas heater circuit to make the hot gas discharged from a compressor flow into an evaporator and heat the vehicle passenger compartment, at which time, when a suction pressure (Ps) of the compressor becomes a low pressure below a first predetermined pressure, the discharge volume (Vc) of the compressor is made larger to ensure a sufficient auxiliary heating performance. Further, when the hot gas is made to flow into the evaporator to heat the vehicle passenger compartment, if the suction pressure (Ps) of the compressor becomes a higher pressure over a second predetermined pressure, the discharge volume (Vc) of the compressor is made smaller to protect the refrigeration cycle parts and lighten the ON, OFF shock.

摘要： A viscous heater (9) for heating cooling water for cooling a water cooled engine (E) is disposed in a cooling water circuit (W), and a front heater core (15) is disposed in the cooling water circuit at a downstream side of the viscous heater with reference to a flow direction of the cooling water. Only when a heating operation is the maximum heating operation or the maximum heating operation is desired, a viscous clutch (7) is turned on to transmit a driving force of the engine to the viscous heater. When the maximum heating operation is not desired, the viscous clutch is turned off so that the driving force of the engine is not transmitted to the viscous heater. Therefore, a load of the engine is reduced, and the cost for running the vehicle can be lowered.

摘要： A viscous fluid type heat generator which includes a housing assembly defining a heat generating chamber (5) and a heat receiving chamber (13,14) arranged adjacent to the heat generating chamber via a partition wall (2,3) disposed therebetween. A rotor element (11) is mounted to be rotated by a drive shaft (8) for rotation within the heat generating chamber (5). A viscous fluid is held in a gap defined between the inner wall surfaces of the heat generating chamber (5) and the outer faces of the rotor element (11), for heat generation under shearing stress applied by the rotation of the rotor element (11). A heat exchanging fluid circulates through the heat receiving chamber (13,14) to receive heat transferred through the partition wall from the heat generating chamber. A plurality of grooves (23a,23b) are formed on at least one of the inner wall surfaces of the heat generating chamber (13,14) to increase a total heat transfer surface area in the inner wall surfaces, and thus to enhance a heat transfer efficiency through the partition wall. The density of arrangement of the grooves (23a,23b) in the outer peripheral area of the inner wall surface is larger than that in the inner peripheral area of the latter.

摘要： The heating system for the vehicle uses the engine coolant circuit to heat a heat exchanger (15) in the air inlet into the vehicle. To boost the heat output from the engine, an additional heater is fitted comprising a hydraulic unit (7) which heats the coolant through a shear effect generated by a rotor. The viscous effect heater is driven by a belt drive which also drives the hydraulic servo pump (P) and the air conditioning compressor (31). A solenoid operated clutch (6) connects the viscous heater to the belt drive. The viscous heater is activated if the steering is turned slightly when the vehicle is not moving. This enables the heater to supplement to low thermal output of the engine. If the steering turned by a larger amount the control system detects the increased in torque and gives priority to the hydraulic servo circuit by disconnecting the viscous heater and the compressor of the air conditioning system. This relieves torque on the belt drive.

摘要： According to the present invention, when an air-conditioning clutch (27) of a compressor is set on, even if an improvement of a heating capacity by a viscous heater (4) is required, a viscous clutch (7) is turned off not to transmit a rotational driving force of an engine (E) to a rotor (53) of the viscous heater, and further the rotational driving force of the engine is transmitted to the compressor. In this way, a torque applied to the engine E and a V-belt (6) can be reduced, so that a fuel consumption ratio of the engine lowers and a fuel economical performance improves. Further, because an operation of the compressor is intermitted, it is possible to remove a fog of a front windshield, so that a safety of the vehicle travelling can be prevented from being deteriorated.
