摘要： A heating apparatus for a vehicle includes a heat exchanger for implementing heat exchange between coolant which has cooled an engine and air directed to a vehicle interior to heat the vehicle interior. A viscous heater has a rotor and a heating chamber containing viscous fluid. The rotor rotates when being subjected to rotational power of the engine. The viscous fluid is subjected to a shear force and is heated when the rotor is subjected to the rotational power. The viscous heater heats the coolant fed to the heat exchanger as the viscous fluid in the heating chamber is heated. A clutch is operative for selectively permitting and inhibiting transmission of the rotational power from the engine to the rotor. A belt transmission device connects the engine and the clutch. A physical quantity detecting device is operative for detecting a physical quantity related to a rotational speed of the rotor. A control device is operative for controlling the clutch to inhibit the transmission of the rotational power from the engine to the rotor when the physical quantity detected by the physical quantity detecting device is equal to or less than a predetermined value.

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： A method for controlling a viscous heater (22) for a vehicle. The vehicle has an engine (11), a radiator (14), a passage (13), the radiator (16) and the viscous heater (22). The radiator (16) heats the passage (13) using heat from the coolant. The viscous heater (22) uses the driving force of the engine (11) to heat the coolant separately from the engine (11) cooling system. The method includes a step of cutting off the transfer of the driving force of the engine (11) to the viscous heater (22) when the engine (11) is being started. The method also includes a step of transferring the driving force of the engine (11) to the viscous heater (22) when the engine (11) is running.

摘要： The refrigerating system includes a compressor (1), a gas cooler (2) used as a heat-dissipation type heat exchanger, an expansion valve (3) used as a throttling means, an evaporator (4) used as a heat-absorption type heat exchanger and an accumulator (5), which are connected in series with each other to form a closed circuit. The closed circuit is adapted so that the higher pressure of the closed circuit becomes the supercritical pressure of a refrigerant circulating the closed circuit. This has a control characteristic property wherein the lower evaporating pressure increases as the higher pressure increases. The lower evaporating pressure and the higher pressure are detected, respectively, and if the detected value of the lower evaporating pressure is lower than a target value for the lower evaporating pressure determined based on the above control characteristic property in correspondence to the detected value of the higher pressure, the discharge capacity of the compressor (1) is reduced so that the lower evaporating pressure coincides with the target value.

摘要： An air conditioning system 100 may include a compressor 101 having a driving chamber110, a cooling circuit 151, a heating circuit 152 and a controller 189. This system may release high pressure refrigerant from the compressor discharge port 120 into the compressor driving chamber 110 by means of the controller 189. The controller 189 may include a selector 181, a first refrigerant releasing means 183 and a second refrigerant releasing means 185. The selector 181 connects the discharge port 120 and the driving chamber 110 by both the first and second refrigerant releasing means 183, 185 when discharge pressure of the refrigerant has reached a predetermined high-pressure state during operation of the heating circuit 152. When the discharge pressure of the refrigerant results an abnormal high pressure state during the operation of the heating circuit 152, the high pressure refrigerant is released from the discharge port 120 into the driving chamber 110 not only by a single refrigerant releasing means 185 but by double refrigerant releasing means 183, 185. Therefore, the high pressure refrigerant can be swiftly released into the driving chamber 110 to increase the pressure in the driving chamber 110 and the necessary time for reducing the compressor discharge pressure can be minimized. Thus, the abnormal high discharge pressure can be quickly alleviated.

摘要： A viscous heater is provided with a front side plate 2 and a rear side plate 3, which are arranged so that a heat generating chamber 5 is formed between their facing back surfaces and which are stored in a housing so that heat emission chambers FW and RW are formed between the side plates and the housing. The housing is formed by a front housing having a tubular part 1c which extends axially for storing the front and side plates radially inwardly of the tubular part 1c and a rear housing 4. Thus, sealing is necessary only at a location where the front and rear housings 1 and 4 are connected with each other. Thus, a very simple structure is sufficient for preventing any leakage of the recirculated fluid.
