In an air conditioner for an automobile, restriction on arrangement of electric apparatus is removed, small-sized and light-weighted formation is achieved by promoting cooling capacity of the electric apparatus by a cooling fluid by an inexpensive constitution and firm defrosting is enabled by closing an air flow path of an exterior heat exchanger. For that purpose, there are provided a refrigeration cycle having an electrically driven compressor and an exterior heat exchanger and a radiator used in an electric automobile having a driving motor for driving the automobile and a motor driving power source for driving the driving motor and connected to cool a heat generating electric apparatus such as the driving motor or the motor driving power source via the cooling fluid, the radiator is arranged in the air flow path of exterior fan and an opening and closing apparatus for opening and closing the air flow path of the exterior heat exchanger is provided.

A scroll compressor with two scrolls including respective scroll wraps to form a compression chamber therebetween so that a volume of the compression chamber is decreased to compress a fluid therein by an orbital motion between the scrolls around an axis, has a frame supporting the scrolls thereon, a drawing force generator generating a drawing force urging axially one of the scrolls toward another one thereof, and a contacting force limiter bearing at least a part of the drawing force to prevent the at least a part of the drawing force from being born by a contact between the scrolls, when an axial distance between the scrolls is not more than a predetermined axial distance.

In a refrigerator, an intermediate heat exchanger as an evaporator in the refrigeration cycle 11 in which a flammable refrigerant is sealed is provided inside of a heat insulating material. A heat transferring device is provided between the intermediate heat exchanger and a heat exchanger for cooling. At the time of stop and occurrence of the refrigerant leakage, the refrigerant inside of the intermediate heat exchanger is recovered into the condenser or into the refrigerant recovery cylinder so that even if the refrigerant leaks out, a leaked amount of the refrigerant into the refrigerator is reduced.

The present invention relates to air conditioning systems and more particularly to an air conditioning system which provides air conditioning in each of a plurality of spaces. The air conditioning system according to the present invention divides a space with partitions into a plurality of air conditioning spaces and controls the temperature by cooling and heating mediums supplied from an external heat source using a three-way valve and an expansion valve. The air conditioning system includes an ID card for identifying a person which uses the air conditioning system. If a person is present to use the air conditioning system, the set or measured values of the environmental conditions for that person is stored. When that person again uses the air conditioning system, the system calculates the environmental conditions stored by the person in accordance with his stored set or measured environmental condition values. Each of the individuals' preferred comfortable environments is automatically realized by calculating the set values for that person in accordance with his current or past set conditions independent of the space. Changes to his preference to the environmental conditions are easily made.

A refrigerating apparatus including a first compressor, a condenser, a first pressure reducer a first evaporator, a second pressure reducer and a second evaporator connected together by lines to form a refrigerating circuit for a refrigerant to flow therethrough, wherein a second compressor is connected at its suction side to the second pressure reducer for receiving gaseous component of refrigerant from the first evaporator and connected at its discharge side to the line between the first compressor and the condenser. An evaporative pressure control valve may be mounted in the line between the first evaporator and the second pressure reducer or the line between the second pressure reducer and the second evaporator. A bypass line mounting an electromagnetic valve may connect the line between the first evaporator and the second pressure reducer to the line between the second pressure reducer and the second evaporator.
