Title:
EJECTOR MODULE
Document Type and Number:
Japanese Patent JP2019020064
Kind Code:
A
Abstract:
To provide an ejector module which can suppress the lowering of a temperature adjustment capacity of an ejector-type refrigeration cycle, and can sufficiently obtain a COP improvement effect irrespective of a load variation.SOLUTION: A bypass passage 20e for introducing a refrigerant flowing out of an outdoor heat exchanger to a throttle-side outlet 21d by making it bypass a throttle passage 20a of a variable throttle mechanism 26, and a module opening/closing valve 27 for opening and closing the bypass passage 20e are arranged at an ejector module 20 in which an ejector 25 and the variable throttle mechanism 26 are integrated with each other. Then, at a cooling mode for cooling blown air, a throttle opening of the variable throttle mechanism 26 is properly adjusted according to a load variation. Furthermore, at a dehumidification heating mode for reheating the blown air which is cooled and dehumidified by a suction-side evaporator 17 and a flow-out side evaporator 18 by an indoor condenser, the reduction of a heat absorption amount of the refrigerant at the outdoor heat exchanger is suppressed by the opening of the bypass passage 20e by the module opening/closing valve 27.SELECTED DRAWING: Figure 2
