摘要:
An air conditioner for a vehicle has a heat pump type refrigerant circuit capable of operating at least in a heating mode. The air conditioner comprises a motor fan for supplying air heated by a heat exchanger to the interior of the vehicle during operation of the heating mode, a sensor for detecting the temperature of the air at a position downstream of the heat exchanger and a control unit for controlling the volume of the air supplied by the motor fan to a predetermined minimum volume by controlling the drive of the motor fan when the detected air temperature is lower than a predetermined temperature. Even in a condition where a sufficiently large heat radiation from the heat exchanger cannot be expected, a large volume of cold air that has been insufficiently heated can be prevented from being discharged into the interior of the vehicle. Because the motor fan is driven at a condition of minimum air volume even when the detected temperature is lower than the predetermined temperature, a rapid variation of air volume caused at the time of changing a fan-stopping condition to a fan-driving condition can be avoided and an abnormal increase in the discharge pressure of the heat pump compressor can be prevented.

An automotive air conditioning system comprises a heat pump type refrigerant circuit charged with a first refrigerant and includes first and second internal heat exchangers disposed within an air conditioning duct and an external heat exchanger located outside the duct. A plurality of electromagnetic valves are selectively operated so that in one operational state the external heat exchanger performs as an evaporator and the second internal heat exchanger performs as a condenser, and such that in another operational state the external heat exchanger and the first internal heat exchanger perform as evaporators and the second internal heat exchanger performs as a condenser. A first pressure equalizing type expansion valve mechanism associated with the external heat exchanger has a P-T characteristic curve wherein a static superheat curve intersects with a saturated first refrigerant vapor curve when the temperature of the first refrigerant immediately upstream of the external heat exchanger is in a low range. A second pressure equalizing type expansion valve mechanism has a P-T characteristic curve wherein a static superheat curve generally extends parallel to a saturated first refrigerant vapor curve.
摘要:
An external heat exchanger of a heat pump air-conditioner on an electric vehicle is determined as being frosted based on signals from temperature sensors. If the external heat exchanger is frosted, then a frosting flag is set and the air-conditioner is operated in a cooling mode to radiate heat from the external heat exchanger for thereby defrosting the external heat exchanger while the air-conditioner is in a pre-air-conditioning mode before the driver enters the electric vehicle or while the battery on the electric vehicle is being charged. While the battery is being charged, the external heat exchanger is defrosted by the electric energy supplied from an external power supply to charge the battery.
摘要:
The present invention is directed to a control apparatus for use in an automotive air conditioning system which includes a variable capacity-type refrigerant compressor. The automotive air conditioning system comprises a refrigerant circuit including a refrigerant compressor with an externally controlled, variable capacity control mechanism; an evaporator connected to a suction chamber of the compressor; and a control apparatus which controls refrigerant circuit operation. The control apparatus includes an adjusting device for adjusting a control point of the compressor suction chamber pressure. During operation of the automotive air conditioning system, the control point of the compressor suction chamber pressure is adjusted to effectively maintain the temperature of air immediately downstream from the evaporator at the set temperature. In one situation in which the automotive air conditioning system is operated in a static thermodynamic condition of the evaporator, the control point of the compressor suction chamber pressure is adjusted to effectively converge the temperature of air immediately downstream from the evaporator to the set temperature. In another situation in which the automotive air conditioning system is operated in a dynamic thermodynamic condition of the evaporator, the control point of the compressor suction chamber is also adjusted to effectively converge the temperature of air immediately downstream from the set temperature. Accordingly, the passenger compartment of the automobile can be more effectively air conditioned during operation of the automotive air conditioning system.

This invention relates to a novel influenza vaccine comprising a complex of HANA antigen and an MDP derivative.The novel vaccine is prepared by mixing an influenza HANA antigen and at least one MDP derivative in a suitable medium; solubilizing the resulting mixture with a surface active agent capable of being removed by dialysis, the solubilization being conducted in the presence or absence of cholesterol, lecithin and dicetyl phosphate or a mixture thereof; and then removing the surface active agent therefrom by dialysis to obtain an influenza vaccine comprising artificial vesicle-like particles of a complex of HANA antigen and MDP derivative, where the MDP derivative forms a membrane of the particle (corresponding to the lipid membrane of natural influenza virus particle) on the surface of which there exists the HANA antigen being bonded to the MDP derivative so as to form the complex. Thus, said artificial vesicle-like particle of the HANA antigen-MDP derivative complex has nearly the same particle size and shape as the natural influenza virus particle.The novel vaccine has an improved immunogenicity compared with the conventional vaccine.
