Title:
EVAPORATOR, AND TURBO-REFRIGERATING APPARATUS EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/179630
Kind Code:
A1
Abstract:
The present invention maintains a compact evaporator size in a turbo-refrigerating apparatus utilizing a low pressure refrigerant used at a maximum pressure of less than 0.2 MPaG while avoiding efficiency losses and equipment damage that result from carryover of liquid state refrigerant to the turbo compressor side. This evaporator (7) is equipped with a pressure vessel (21) into which a condensed refrigerant is introduced, a refrigerant inlet which is provided to the bottom portion of the pressure vessel (21), a refrigerant outlet which is provided to the top portion of the pressure vessel (21), a heat transfer tube group (25) which passes through the interior of the pressure vessel (21), circulates liquid to be chilled through the interior thereof, and exchanges heat between the liquid to be chilled and the refrigerant, and a demister (27) which is disposed between the refrigerant outlet and the heat transfer tube group (25) in the interior of the pressure vessel (21) and carries out vapor-liquid separation of the refrigerant, a dividing section (27A) (for example, a plurality of notches (27a)) being provided between the periphery of the demister (27) and the inner peripheral surface of the pressure vessel (21). The dividing section (27A) is provided to a side of the demister (27) along the lengthwise direction.
