Title:
SHELL-AND-TUBE HEAT EXCHANGER, REFRIGERATION CYCLE DEVICE, AND HEAT EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2022/130986
Kind Code:
A1
Abstract:
In the present invention, an evaporator 101 is constituted by a shell-and-tube heat exchanger. The evaporator 101 includes: a plurality of heat transfer tubes 22 through which a first fluid flows; and a plurality of nozzles 24 that spray a second fluid toward the plurality of heat transfer tubes 22. When a direction parallel to the longitudinal direction of the plurality of heat transfer tubes 22 is defined as an X direction, a direction vertical to the X direction is defined as a Y direction, and a direction perpendicular to the X direction and the Y direction is defined as a Z direction, the plurality of nozzles 24 include a plurality of first nozzles 24a that spray the second fluid from a first side toward a second side in the Z direction, and a plurality of second nozzles 24b that spray the second fluid from the first side toward the second side in the Z direction. In a projected image obtained by projecting the plurality of first nozzles 24a and the plurality of second nozzles 24b in the Z direction, the plurality of first nozzles 24a and the plurality of second nozzles 24b exhibit a staggered arrangement pattern.
