摘要： PROBLEM TO BE SOLVED: To easily switch cooling medium flow passages at the time of switching between a heating side and a cooling side in a refrigerating cycle using an ejector 5.
SOLUTION: High pressure inflow switching valves 8a, 8b and a low pressure inflow switching valve 9 which switch flow passages for a cooling medium which flows into an ejector 5 using a pressure difference therebetween are provided on the upstream sides of a high pressure inflow part 5a and a low pressure inflow part 5b, respectively, of the ejector, so that the high pressure cooling medium always flows into the high pressure inflow part 5a and the low pressure cooling medium always flows into the low pressure inflow part 5b even when a four-way valve 2 is switched. By virtue of such a simple configuration, the flow passages for the cooling medium which flows into the ejector 5 are automatically switched, so that the high pressure cooling medium always flows into the high pressure inflow part 5a and the low pressure cooling medium always flows into the low pressure inflow part 5b. Due to this, in the refrigerating cycle using the ejector 5, the switching between the heating side and the cooling side can be easily attained simply by providing the four-way valve 2 at an outlet of a compressor 1 to change the flowing direction of the cooling medium.

摘要翻译：要解决的问题：使用喷射器5在制冷循环中在加热侧和冷却侧之间切换时容易地切换冷却介质流路。解决方案：高压流入切换阀8a，8b 以及分别在高压流入部5a和低压流入部5b的上游侧设置有切换流入喷射器5的冷却介质的流路的低压流入切换阀9，使得高压冷却介质总是流入高压流入部分5a，并且低压冷却介质总是流入低压流入部分5b，即使当四通阀2被切换时也是如此。由于这样简单的结构，流入喷射器5的冷却介质的流动通道被自动切换，所以高压冷却介质总是流入高压流入部分5a，并且低压冷却介质总是流入低压流入部5b。因此，在使用喷射器5的制冷循环中，通过在压缩机1的出口设置四通阀2，可以容易地实现加热侧和冷却侧之间的切换，以改变压缩机1的流动方向冷却介质。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a refrigeration apparatus capable of avoiding pressure rise of a refrigerant in a high pressure side due to increase of refrigerant flow rate and simultaneously raising cooling capacity corresponding to the increase of the refrigerant flow rate.
SOLUTION: A bypass passage B is provided for making part of a refrigerant flowing out of a refrigerant radiator 2 bypass an ejector 3 to flow into a gas- liquid separator 4. Control valves 7, 70 and 9 are provided in the halfway of the passage B. When the refrigerant flowing out of the radiator 2 comes to a specific pressure condition, the valves 7, 70 and 9 are opened to allow the refrigerant to flow into the passage B. Thus, the pressure of the refrigerant is surely prevented from being excessively raised, and a refrigeration cycle is stably operated. Further, even when the flow rate of the refrigerant increases, power for a refrigerant compressor 1 is prevented from increasing so that efficiency of the cycle is enhanced. Cooling capacity is raised corresponding to the increase of the refrigerant flow rate.

摘要： PROBLEM TO BE SOLVED: To defrost two evaporators even when a pressure reducer of a simple constitution is used. SOLUTION: In this heat pump cycle in which the refrigerant flowing in a branch passage 16 is introduced into the first evaporator 15 after passing through the second evaporator 18, the second pressure reducer 17 includes a valve element operated according to anteroposterior differential pressure and changing a passage area of the branch passage 16, and is constituted to increase the passage area in the branch passage when the anteroposterior differential pressure of the valve element is less than a set value. An electric control device 20 controls the operation of the heat pump cycle so that the anteroposterior differential pressure of the valve element is kept to be less than the set value in a defrosting operation mode. In the defrosting operation mode, a high-temperature high-pressure refrigerant is introduced to the second evaporator 18 in a state of keeping its high temperature and hardly reduced in its pressure by the second pressure reducer 17, the high-temperature high-pressure refrigerant is introduced to the first evaporator 15 after passing through the second evaporator 18, so that two evaporators are defrosted.

摘要： PROBLEM TO BE SOLVED: To provide a heat pump cycle for stabilizing desired heat absorbing capability for a long period.
SOLUTION: An evaporator 40 is arranged between an ejector 30 and a gas-liquid separator 50. Thus, refrigerant discharged from a compressor 10 is circulated in the evaporator 40, and so the amount of the refrigerant discharged from the compressor 10 is secured even when the pumping capability of the ejector 30 is greatly changed with an individual difference (manufacturing dispersion) or a secular change of the ejector 30. The great change in the amount of the refrigerant to be circulated in the evaporator 40 is suppressed to stabilize the desired heat absorbing capability for a long period. The flow rate of the refrigerant in the evaporator 40 is increased to increase heat transmissivity between the refrigerant and the evaporator 40. The heat exchanging capability, namely, the heat absorbing capability of the evaporator 40 is improved without increasing the size of the evaporator 40, resulting in the improved operating efficiency of the heat pump cycle.

摘要： PROBLEM TO BE SOLVED: To provide a blower capable of reducing noise accompanied by rotation of a fan.SOLUTION: Although vortexes due to collision of air flow easily occur on a narrow part 32 of the upper side and the lower side in the vehicle vertical direction within a shroud 16, the shroud 16 has a protrusion part 34 on the narrow part 32 and, therefore, the collision of air flow in an air channel of the shroud 16 can be suppressed. As the result, the occurrence of vortexes due to collision of the air flow, that is, the occurrence of disturbance of the air flow is suppressed and the occurrence of noise accompanied by rotation of an axial fan 14, that is, the occurrence of NZ sound can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a refrigerant cycle with an ejector capable of improving COP and properly air-conditioning an air-conditioned space in both of a cooling operation mode and a heating operation mode.
SOLUTION: First and second four-way valves 12a, 12b switching a refrigerant flow channel, switches the flow channel to branch the refrigerant flowing out from an outdoor heat exchanger 13 to supply one of the refrigerants to a nozzle portion 18a of the ejector 18, and supply the other refrigerant to a using-side heat exchanger 14 while decompressing and expanding the refrigerant, and sucking the refrigerant from a refrigerant suction opening 19b of the ejector 18 in the cooling operation mode. As the liquid-phase refrigerant can be surely supplied to the using-side heat exchanger 14 by utilizing refrigerant sucking/discharging capacity of a compressor 11 even in a cycle constituted in such manner that the liquid-phase refrigerant is hardly supplied to the heat exchanger acting as an evaporator in the cooling operation mode with respect to the heating operation mode, the air-conditioning of the air-conditioned space can be properly performed in both operation modes.
