摘要:
According to the present invention, a hot water type heating apparatus includes a heat exchanger and a flow quantity control valve which controls a quantity of hot water to the heat exchanger. The flow quantity control valve includes a valve housing provided with a first inlet pipe to which the hot water flows, a first outlet pipe which returns hot water to an engine, a second outlet pipe which directs the hot water to the heat exchanger, a second inlet pipe to which the hot water from the heat exchanger flows and a bypass circuit which selectively connects the hot water from the first inlet pipe directly with the first outlet pipe, and a valve body for adjusting an opening area between the first inlet pipe and the second outlet pipe. The first inlet pipe and the first outlet pipe extend from a passenger compartment of a vehicle to an engine room thereof, thereby simplifying the work for connecting these pipes.
摘要:
To control fluctuation of blown air temperature of a heat exchanger to a small value without adding a movable mechanism such as a variable restricting valve, a heat exchanger for heating air by exchanging heat between hot water supplied from a water-cooling type engine and air, a flow control valve for controlling a hot water flow amount to the heat exchanger and a bypass circuit for allowing hot water to flow while bypassing the heat exchanger are provided. A pressure-responsive valve is provided on the bypass circuit and an opening degree of the bypass circuit corresponding to a pressure rise of the hot water is increased. The flow of returning hot water from the heat exchanger is blocked by the flow of the bypass side hot water at a merging portion where the bypass side hot water discharged from the pressure-responsive valve merges with the returning hot water discharged from the heat exchanger.

A flow-quantity control valve controlling hot-water flow to a heat exchanger and a bypass circuit allowing hot water to bypass the heat exchanger are provided along with a pressure-actuated valve in the bypass circuit which is responsive to a pressure increase of hot water from an engine. Inlet-side opening portions, outlet-side opening portions, and a bypass-side opening portion are provided in a control passage of a valve body of the flow-quantity control valve. Main flow of dynamic pressure of hot water sprayed from portions on a small opening-degree side act upon a valve body side of the pressure-actuated valve. Due to this, dynamic pressure of the hot water in a small opening-degree region of the flow-quantity control valve can be effectively used to increase a valve-lift quantity of the pressure-actuated valve, thereby reducing a fluctuation range of blown-air temperature of the heat exchanger. Also, the flow may be bent so that hot-water flow having a high dynamic-pressure component from the hot-water inlet pipe is not applied directly to the valve body of the differential-pressure valve; thus, lift of the differential-pressure valve can be prevented from becoming excessive, and a drop in heat-exchanger blown-air temperature at a predetermined opening-degree position of a flow-quantity control valve can effectively be suppressed.

An air conditioning apparatus for a vehicle includes a heat exchanger for heating air to be blown into a passenger compartment of the vehicle using hot water as a heating source, a plurality of electric heating members formed integrally with the heat exchanger, and a control unit for controlling electric power supplying to the electric heating members and an amount of air blown from a blower. The control unit controls the amount of air blown from the blower based on a heat-radiating amount from the electric heating members and a target temperature of air blown into the passenger compartment. Thus, even when number of the electric heating members to be turned on is changed, the temperature of air blown into the passenger compartment can be set to the target temperature by controlling the amount of air blown from the blower. As a result, the passenger compartment can be effectively quickly heated using the electric heating members.

A vehicle air-conditioning system includes electric heating devices to accelerate a rise in temperature of air for heating a passenger compartment by accelerating a rise in temperature of warm water used to heat the air and by directly heating the air. Electric heating devices are built into a heat exchanger for heating so that the devices can release heat into surrounding air through radiating fins. When the system is in a heating operation region and the temperature of warm water available to flow through the heat exchanger is below a set temperature T.sub.2, the electric heating devices are turned on. A blower for blowing heating air into a passenger compartment through the heat exchanger is stopped, and a warm water valve is opened to allow the warm water to flow through the heat exchanger, whereupon heat from the electric heating devices is released through the radiating fins into the warm water inside the heat exchanger. When the temperature of the warm water rises above the set temperature T.sub.2, the blower is started, and heat from the electric heating devices is released through the radiating fins into the air blown by the blower.

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.

A battery unit includes a module assembly, a housing that houses the module assembly, and a blower. The module assembly includes a stack of battery modules, and defines a first surface and a second surface opposite to the first surface. The blower is disposed at an end of the module assembly. A rotation shaft of the blower is located between a first plane that includes the first surface and a second plane that includes the second surface. The blower is configured to supply air toward the first surface of the module assembly in a direction perpendicular to a stacking direction of the battery modules. The air is supplied over a range that is substantially equal to a dimension of the module assembly in the stacking direction.
