Problems solved by technology

[0012] As an alternative to vortex tubes, traditional techniques such as compressors can be used to create temperature differences, but are less efficient
If used alone, vortex tubes are generally uneconomical in their capacity for cooling / heating large spaces

Embodiment Construction

[0040] like figure 1 It can be seen that the PCM heat exchanger arrangement according to the invention comprises at least two regenerative heat exchanger units 1a and 1b operating according to the principle of regenerative counter-flow, through which the air, gas or liquid flow follows Alternating and alternately reversed opposite flow directions are directed into and out of the device. Air flow is indicated by arrows 22 and 24 . The solid arrows 22 show the air flow in one cycle and the dashed arrows 24 show the air flow in the second cycle. The change of direction of the air flow in the units 1a and 1b can be achieved by means of known technical devices, such as diverters, fans, reflectors, flaps, or wheel diverters. These known art devices for changing the direction of the air flow in the units 1a and 1b are shown schematically by means of parts 26a and 26b.

[0041] Alternatively, as a variation on the air flow to two units, a single rotary type recuperator could be us...

Abstract

The invention relates to a phase change material (PCM) heat exchanger device comprising heat exchanger cells (1a, 1b) operating on the regenerative countercurrent principle, phase change material (PCM) accumulators (2, 3) provided in the heat exchanger cells and a vortex tube (6, 7, 8). When the directions of the air, gas and liquid flows are cyclically reversed in the apparatus, energy is recovered into the heat exchanger cell and the PCM accumulator, and during the subsequent cycle, the energy is released from the heat exchanger cell and PCM accumulator. While one heat exchanger cell and PCM accumulator is being charged, the other heat exchanger cell and PCM accumulator are simultaneously discharged. The cool / hot flow from the vortex tube is used to enhance / create needed temperature differences. The invention is applicable to buildings, vehicles, climate control rooms, single or multiple devices such as computers, and in various processes, such as, but not limited to, cryogenic methods, and in space technology and supercritical carbon dioxide applications.

Description

[0001] This application is the national phase of a patent application submitted on October 10, 2006, with the international application number PCT / F106 / 050434, and published in English on April 19, 2007, with the international publication number WO 2007 / 042621. technical field [0002] The present invention relates to a heat exchanger comprising a recuperator operating according to the counterflow principle, a phase change material (PCM) enthalpy accumulator in the recuperator and / or using a Venturi The vortex tube of the tube phenomenon. The above system provides pre-cooling and pre-drying of fresh ventilation air in summer and pre-heating and pre-humidification of fresh ventilation air in winter. The system can also be used without ventilation. In addition to buildings, the invention can be used in vehicular, industrial and commercial equipment rooms, and any closed compartment requiring controlled environmental conditions, for example in workshops and in equipment such as ...
