摘要： A refrigerant cycle includes an ejector having a throttle changeable nozzle. In the refrigerant cycle, a control valve having a needle valve controls a pressure of a middle-pressure refrigerant in a bypass passage, and a pilot valve controls a throttle opening degree of the nozzle in accordance with a pressure difference between the pressure of the middle-pressure refrigerant in the bypass passage and the refrigerant pressure in a high-pressure refrigerant inlet port of the ejector. When an opening degree of the needle valve is changed in accordance with a load variation or a load state, the pressure of the middle-pressure refrigerant in the bypass passage is changed. Accordingly, the moving position of the pilot valve is controlled, and the throttle opening degree of the nozzle is controlled.

摘要： An automotive climate control system is disclosed. As long as an ignition switch is off, a bypass (14) is closed (in this state, a ratio between warm air and cool air is a maximum when the automotive climate control system is activated.), the blowout is set to defrost mode and the introduced air is set to external air mode regardless of the preceding modes of blowout and introduced air (when the ignition switch is on). As a result, the refrigerant leaking from an evaporator (12) flows to an external air inlet (23) smaller in air resistance. Even in the case where the ignition switch is off, therefore, the leaking refrigerant is prevented from flowing into the cabin.

摘要： A thermal expansion valve for automotive coolant systems which is significantly more compact than previously developed expansion values. The housing of the expansion valve is divided into a first housing formed in a cylindrical shape with a bottom and a second housing formed in a columnar shape. The first housing is fit into the second housing, and both are integrally connected to each other. A temperature sensing mechanism having a temperature sensing chamber and an expansion mechanism for adjusting an opening degree of a throttle passage in accordance with an evaporator outlet temperature sensed by the temperature sensing means are disposed in the second housing. First and fourth joint portions connected to inlet and outlet refrigerant pipes of the evaporator, respectively, are at the bottom of the first housing. On the other hand, second and third joint portions connected to a compressor suction side refrigerant pipe and a high-pressure side refrigerant pipe from a receiver, respectively, are at an outer surface of the second housing. In this manner the overall size of the expansion valve is reduced considerably, thus saving valuable space in an engine compartment of a vehicle.

摘要： The air heating capability of an indoor heat exchanger is limited to set the temperature of the indoor heat exchanger to a first predetermined temperature Tel or lower during heating. Thereby, fogging is prevented through re-evaporation of the condensed water in the indoor heat exchanger during heating within an air-conditioning apparatus with a hot water heater core using hot water as the heat source and the heating circuit.

摘要： Heat exchange is performed between a discharge side refrigerant and a suction side refrigerant also at the time of a heating operation. By this, a liquid phase refrigerant containing lubricating oil in the suction side refrigerant is heated by the discharge side refrigerant, and the liquid phase refrigerant is vaporized also at the time of the heating operation, so that the amount of the liquid phase refrigerant sucked into a compressor is decreased. Accordingly, the increase of compression work of the compressor is prevented, and an opening area of an oil return hole can be expanded to such a degree that an optimum amount of lubricating oil is attained at the time of the heating operation.

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.
