摘要： A refrigerant cycle system includes a condenser having a condensation portion for condensing refrigerant discharged from a compressor, and a receiver for separating refrigerant from the condensation portion into gas refrigerant and liquid refrigerant, and for storing the liquid refrigerant. In this system, refrigerant from the condensation portion flows into the receiver through a first communication hole, and liquid refrigerant in the receiver is discharged through a second communication hole in which a pressure loss is generated. Further, gas refrigerant at an upper side in the receiver is discharged to a downstream side of the second communication hole through a gas bypass pipe.

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： 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： A main evaporator cools a driver's compartment of a vehicle while a cooling storage evaporator cools cooling storage packs that are used in cooling a sleeping compartment. Refrigerant is supplied to the main evaporator at the actuation of a first solenoid valve while refrigerant is supplied to the cooling storage evaporator at the actuation of a second solenoid valve. If a first switch is being actuated after the completion of the cooling storage operation of the cooling storage evaporator on the cooling storage packs and the temperature of the cooling storage packs is no more than a preset temperature, for example, -5.degree. C., FIR control is performed for alternately actuating the first solenoid valve and the second solenoid valve based on a predetermined time ratio (for example, 10 minutes 15 seconds).
