摘要： A refrigerator for a vehicle has a coldness accumulator formed by a container with water therein and an evaporator selectively connectable to a refrigeration cycle of an air conditioner of the vehicle. The coldness accumulator is disposed in a refrigeration space defined in a heat-insulating housing having an openable door mounted thereon. The water is cooled to freezing temperature during vehicle operation to accumulate coldness which is utilized to keep the refrigeration space at a low temperature when the evaporator is disconnected from the refrigeration cycle or when the refrigeration cycle is not operated.

The cooling unit includes a refrigerator evaporator connected to a refrigeration cycle of an automotive airconditioning refrigeration cycle on a vehicle and a coldness accumulating medium supported in heat exchange relationship with the evaporator. During evaporator operation, the coldness is accumulated in the coldness-accumulating medium and simultaneously transferred to the goods in the cool-keeping container. When the goods are cooled to a desired temperature, the cool-keeping container can be disconnected from the cooling unit and taken out of the vehicle with a heat insulating lid closing an opening formed in the container for the insertion and removal of the goods into and out of the container.

摘要： An air conditioning apparatus for an electric car capable of preventing condensation from forming on windshields, while decreasing electric power consumption. A duct forms therein a first passageway connecting an inside air inlet 8 with a lower outlet (foot outlet) 10 for discharging an air flow toward a lower part of a passenger in a cabin, and a second passageway for connecting an outside air inlet 11 with a defroster outlet 12 for discharging an air flow toward an inside surface of a windshield. A heat exchanger(s) is (are) arranged in the duct to make contact with the flow of air in the first and second passageways so as to heat the flows of air therein. The inside air after being heated by the heat exchanger is discharged from the lower outlet 10 to the cabin, while the outside air after heating is discharged from the defroster outlet 12 toward the windshield.

摘要： A refrigeration system for use in air conditioner for automobiles. The refrigeration system has a pressure reducing device disposed between a condenser and an evaporator and adapted for permitting the refrigerant to make an adiabatic expansion therethrough. The pressure reducing device includes a flow restricting and resisting means such as an orifice and a flow resisting means disposed at the upstream side of the flow restricting and resisting means. The flow resisting means are adapted to impart a resistance to the flow of refrigerant and may be constituted by a capillary tube or a constant-pressure-differential valve. Because of the resistance imparted by the flow resisting means, the dryness factor of the refrigerant at the inlet to the flow restricting and resisting means is maintained between 0 and 0.1, so that the flow rate of the refrigerant is largely affected by the characteristic of the flow restricting and resisting means. Consequently, it is possible to vary the flow rate of the refrigerant over a wide range while maintaining the degree of subcooling of the refrigerant, i.e. at the inlet side of the flow resisting means, at a suitable level for an efficient operation of the refrigeration cycle.

摘要： A centrifugal type separator is disposed on a downstream side of a temperature-operating type expansion valve. Liquid-phase refrigerant separated herein is again pressure-reduced by an aperture resistance and thereafter inducted to an inlet side of the evaporator by means of a liquid-phase refrigerant discharge passage. Meanwhile, gas-phase refrigerant separated by the separator is returned directly from a gas-phase refrigerant discharge passage to an evaporator outlet side passage, and after being united with superheated gas-phase refrigerant evaporated by the evaporator, is taken into a compressor. A temperature-sensing tube of the expansion valve is disposed further on the downstream side of the foregoing union location so as to enable the temperature of the superheated gas-phase refrigerant evaporated by the evaporator to be sensed accurately.

摘要： According to the present invention, a thermal expansion valve for a refrigerating cycle includes a housing having a throttle passage therein for expanding the refrigerant thereinto from the high-pressure side liquid refrigerant circuit, a valve element provided within the housing for adjusting opening degree of the throttle passage, and a thermosensitive element movably disposed within the housing. The thermosensitive element includes a case and a pressure responding member disposed within the case and displacing according to temperature and pressure of the refrigerant at the exit of an evaporator. The case of the thermosensitive element is integrally connected to the valve element, and the thermosensitive element and the valve element are so constructed as to integrally move according to the displacement of the pressure responding member. Accordingly, even if the valve element vibrates due to the sharp expansion of the refrigerant and the vibration transmits to the thermosensitive element case, as the thermosensitive element case is movable with respect to the housing and the housing are separated from the thermosensitive case, most of the vibration is prevented from being transmitted to the housing.
