Abstract
Heat exchanger apparatus which includes a substantially horizontal countercurrent heat exchanger of the shell-and-tube type, particularly for hybrid heat pumps operated with non-azeotropic work fluids. The apparatus further includes fluid distributor with fluid outlets the number of which corresponds to the number of the heat exchanger tubes of the heat exchanger is provided upstream the heat exchanger, the heat exchanger tubes of which are connected each to one fluid outlet of the fluid distributor.
Claims21
Heat exchanger apparatus comprising a substantially horizontal countercurrent heat exchanger of the shell-and-tube type having heat exchanger tubes and operating with non-azeotropic work fluids, characterized in that a fluid distributor with fluid outlets, the number of which corresponds to the number of the heat exchanger tubes of the heat exchanger, is provided upstream of the heat exchanger and the heat exchanger tubes are connected each to one fluid outlet of the fluid distributor.
An apparatus, comprising:
- a horizontally orientated heat exchanger adapted for operation with a non-azeotropic work fluid, said heat exchanger including heat exchanger tubes with each heat exchanger tube having an inlet;
- a work fluid distributor positioned upstream of said heat exchanger and including a first inlet for receiving a gaseous phase of the non-azeotropic working fluid and a second inlet for receiving a liquid phase of the non-azeotropic working fluid, said working fluid distributor including means for distributing the liquid phase and the gaseous phase such that the inlet of each of said heat exchanger tubes receives an even amount of the working fluid in a same gas/liquid proportion received by said first and second inlets of said work fluid distributor.
A heat exchanger apparatus, comprising:
- a substantially horizontal counter-current heat exchanger having a shell-and-tube configuration and essentially horizontally extending heat exchanger tubes;
- a fluid distributor positioned upstream of said heat exchanger and including a shell, fluid outlets opening downwardly from said shell of a number which corresponds to the number of said heat exchanger tubes, vertically orientated liquid distribution pipes positioned in said shell and of a number which corresponds to the number of said fluid outlets and which each terminate above a respective one of said fluid outlets so as to be concentrically positioned with respect to said fluid outlets;
- and
- connection pipes connecting each of said downwardly opening fluid outlets with a respective one of said heat exchanger tubes.
