    摘要： The refrigerant cycle apparatus comprises a communication pipe 32 which is an upper refrigerant flow-in means allowing the refrigerant which has passed through a condenser 2 to flow into the upper part of a liquid receiver 31, and a communication hole 33 which is a lower refrigerant flow-in means allowing the refrigerant which has passed through the condenser 2 to flow into the lower part of the liquid receiver 31, and the flow rate (Gr1) of refrigerant flowing into the upper part of the liquid receiver 31 from the communication pipe 32 is set at a value between 30 kg/h and 110 kg/h. As a result of this, preventing heat damage due to the heat given to the liquid receiver from the outside and securing the good bubble disappearing characteristic of the liquid refrigerant flowing out from the liquid receiver are mutually compatible, and thereby an improved refrigerant filling characteristic may be obtained.

    摘要： In a condenser of a refrigerant cycle, a throttle portion is provided at a predetermined position in one of first and second header tanks to decompress refrigerant while refrigerant meanderingly flows within the one of the first and second header tanks. Therefore, refrigerant from the throttle portion is sufficiently mixed with refrigerant directly flowing from tubes into a downstream space of the throttle portion in the one of the first and second header tanks. Accordingly, even when gas refrigerant is directly introduced from a part of the tubes directly into the lower downstream space, the gas refrigerant can be effectively heat-exchanged with the refrigerant flowing from the throttle portion. As a result, it can restrict refrigerant from being discharged from the condenser in a gas-liquid two-phase state.

    摘要： A refrigeration system which can reduce the amount of moisture permeating into the system, inexpensively and by a simple structure, is disclosed. Rubber hoses (7, 8) capable of absorbing vibrations are arranged on the discharge and the intake sides of a compressor (1). It was found that the amount of moisture in the system can be effectively reduced by reducing the amount of moisture permeating the rubber hose on the discharge side. A freezing limit line is set for defining to a predetermined level the amount of moisture in the system determined by the amount of the refrigerant sealed in the system, the amount of the lubricating oil sealed in the system, the amount of moisture permeation of the hoses (7, 8) and the number of the years elapsed after operation start. The hose (7) on the discharge side of the compressor has a smaller amount of moisture permeation than the hose (8) on the intake side. A hose having a moisture permeation not more than the freezing limit line during a predetermined service life is used as the hose (7) on the discharge side.

    摘要： In a receiver-integrated condenser, a super-cooling portion for cooling liquid refrigerant from a receiving unit is disposed between first and second condensing portions in a core portion in a vertical direction. Therefore, in an engine-idling, even when high-temperature air having passed through the receiver-integrated condenser is introduced again toward an upstream air side of the receiver-integrated condenser through a lower side of the receiver-integrated condenser, the high-temperature air is not introduced toward the arrangement position of said super-cooling portion, because the super-cooling portion is positioned at an upper side from the second condensing portion. Thus, super-cooling performance of refrigerant in the super-cooling portion of the core portion is prevented from being decreased even in the engine idling.

    摘要： A receiver-integrated condenser for a refrigerating system for use in an automotive vehicle is disclosed. The condenser is composed of a heat exchanging core having many tubes extending horizontally in which refrigerant is cooled down and condensed, a pair of header tanks elongated vertically and connected to both ends of the tubes, and a refrigerant receiver for reserving liquid refrigerant therein integrally connected to one of the header tanks which has an inlet joint for receiving overheated refrigerant from a compressor. The inner space of the header tank to which the receiver is connected is divided by a separator into an upper space for receiving the overheated refrigerant and a lower space for receiving refrigerant cooled down in the heat exchanging core. The receiver is connected integrally to the header tank so that it does not overlap with the upper space of the header tank in order to minimize heat transfer from the upper space to the receiver. Thus, the liquid refrigerant reserved in the receiver does not evaporate therein, and a whole space of the receiver is utilized for reserving the liquid refrigerant therein, enabling to fill additional refrigerant in the system without causing a sub-cool temperature rise.

    摘要： Deficiency in the amount of a refrigerant in a refrigeration cycle device is determined based on the amount of decrease in the temperature of an evaporator after a predetermined time period elapses since the actuation of a compressor. The execution of the process for determining deficiency in the amount of refrigerant is prohibited for predetermined time period after the deactuation of the compressor. Therefore, when the temperature of the evaporator does not increase enough after the compressor is actuated, erroneous determination that there is a deficiency in the refrigerant amount can be reliably prevented. In this way, deficiency in the amount of refrigerant in the refrigeration cycle can always be properly determined based on an amount of decrease in the temperature of the evaporator.
