摘要： PURPOSE:To uniformize the rear cabin heating and contrive effective use of the space in such a way that in a room heater for van type vehicle, etc., a heat exchanger, a duct, a fan, etc. are arranged as a room heating unit inside a header panel, and blow-off ports are installed on the side facing the passenger seat. CONSTITUTION:A room heating unit 1 is arranged in a header panel 2 on the side of the driver seat 3, and a blow-off grille equipped with the plural number of hot air blow-off ports 18a are fitted facing the passenger seat. In such a constitution, air imbibed through suction grille by means of a fan 13 is turned out to be hot air through heat exchange with a heat exchanger 14 in a casing 11, and blown off through an air duct 17 from blow-off ports 18a at the blow-off grille 18 into the rear cabin. In such a constitution, room heating in the rear cabin can be uniformized, noise can be prevented, and effective use of the space in the rear cabin can be contrived.

CONSTITUTION:In case of application to a bus vehicle, a cooling unit 2 is set to a rear part ceiling of a car room 1a in a vehicle main unit 1, and an evaporator 3, cooling peripheral air by evaporation of a coolant, is built in the cooling unit 2, then four blowers 4a-4c, blowing air cooled in the evaporator 3 to ceiling blow-off ducts 7, 8 in both sides of the vehicle, are equipped. Here a motor circuit of the blowers 4a, 4b and motor circuit of the blowers 4c, 4d of the four blowers 4a-4d are parallelly connected respectively, while fixed resistors 13, 14 are connected respectively to each parallel circuit. Then a blower speed can be selectively changed by series-parallel circuit switching of said two parallel circuits and combination of the fixed resistors 13, 14.

摘要： PURPOSE:To prevent a secondary failure in a car's room air conditioner by discriminating whether the ratio of an engine rpm. and a revolution number of a cooling compressor has a certain relation or not and by indicating the engagement and disengagement control of a solenoid clutch disposed between the engine and the compressor. CONSTITUTION:By turning a switch 8 on, a discrimination circuit 3 maintains its output at L level in a certain interval so that a relay circuit 4 has one terminal of a clutch 5 grounded for electrification thereof. On the other hand, a lamp 7 is continuously lit via a lamp actuation circuit 6. After the lapse of said interval the discrimination circuit 3 estimates the ratio between both speeds of an engine and a compressor on the basis of respective output signals from an engine rpm. detection means 1A and a compressor revolution speed detection means 2A and if the ratio is estimated to be 0.8 or more, the discrimination circuit 3 maintains the L level, energizing the clutch 5 and lighting the lamp 7. If the speed ratio is reduced to below 0.8 because of a trouble of the compressor during driving, the discrimination circuit 3 is turned to H level, whereby the clutch 5 is deenergized to interrupt the compressor and the lamp 7 is made to flicker. A secondary failure may be thus prevented.

摘要： PURPOSE:To enable successive control of cooling temperature by interrupting operation of a heating heat-exchanger in an operation mode which presents cooling with a cooling heat-exchanger operated at a low efficiency and by placing the actuation and interruption of the cooling heat-exchanger under the intermittent control according to the adjusted position of a damper. CONSTITUTION:When a selection switch 20 is operated into the second operation mode E-A/C, a relay coil 23 will not be powered and a hot water valve 11 is therefore closed so that a heater 5 will not fulfill the heating function. Since a relay coil 24 is then powered, a contact point 24a is closed so that a potentiometer 28 is connected to a thermistor 25 in the series relation. A resistance between an input point Q of a voltage comparison circuit 26 and the earth corresponds to the temperature which is virtually lower than the actual temperature at the lower side of an evaporator 3, hence fluctuated according to the position of a temperature control damper 4. A control circuit 22 may control the synchronism of the intermittent operation of a refrigerant cycle 19 so that the temperature at the lower side of the evaporator 3 may be higher than the reference temperature.

摘要： PURPOSE:To improve the cooling and warming performance for a driver on a rear-seat by blowing-out the wind supplied from an air conditioner for a rear- seat towards the rear-seat from a resistor, passing through the inside of a crossbar, and supplying the cold or warm wind above the rear-seat. CONSTITUTION:A crossbar 1 is extended in the direction of car width at the rear part of a front-seat back B, and an air conditioner 2 for a rear-seat connected to the crossbar 1 is arranged downward in the vertical direction of a car, and a resistor 4 on which a blowing port is opened towards ther rear-seat RS side is arranged onto the crossbar 1. The ventilation wind supplied from the air conditioner 2 is blown above the rear-seat from a resistor 4, passing through the inside of the crossbar 1. In the vicinity of a floor F, a rear heater duct 5 to which a plurality of wind blowing ports 5a for supplying warm wind to the feet of the driver on the rear-seat is installed, and warn wind is blown-out, passing through the front-seat back B and a rear-seat cushion SC. Therefore, cooling and warming performance for the driver on the rear-seat can be improved.

摘要： PURPOSE:To enable to supply a sufficient amount of lubricating oil to a swash plate and other parts of a compressor even at the time of low-load, high-speed operation of the compressor, by employing such an arrangement that the rate of coolant passed through a swash plate chamber is increased with decreasing of the stroke of a piston that is caused by the movement of a control member toward the piston. CONSTITUTION:According as a control member 66 is moved toward a swash plate 18 at the time of low-load operation of a compressor when the pressure of coolant in suction chambers 44F, 44R is lowered, communication between a groove 100, an annular groove 102 and a groove 104 is established, so that coolant in a swash plate chamber 58 is introduced into the suction chamber 44R via the grooves 100, 102 and 104. Therefore, the rate of coolant passed through the swash plate chamber 58 is increased. That is, since the rate of coolant passed through the swash plate chamber 58 is increased with decreasing of the load, it is enabled to supply a sufficient amount of lubricating oil to the swash plate 18 and other parts of the compressor even at the time of low-load, high- speed operation when lubrication tends to be insufficient.

摘要： PURPOSE:To reduce the noise and consumed electric power of a fan, by controlling the energization of a motor for cooling a radiator and another motor for cooling the condenser of a cooler, depending on the temperature of engine cooling water and the running state of an air conditioner. CONSTITUTION:When the temperature of cooling water and the pressure of a coolant for an engine are below prescribed levels, a water temperature switch 13 and a temperature switch 14 are closed. If the main switch 17 of a cooler is open, a first and a second electric motors 5, 6 are stopped. If the main switch 17 is closed, the motor 5, 6 are driven as they are connected in series with each other. When the engine cooling water temperature or the coolant pressure exceeds the prescribed level, the first and the second motors 5, 6 are connected in parallel with each other and driven for full output. The rotational frequency of a fan is controlled depending on the driven state of the motors.
