In this example shown in Figure 9, cooling zone 36 comprises compressor 46, heat radiation chamber 47, turbine 48 and condensation chamber 49, wherein the driving shaft of compressor 46 and turbine 48 mutual coupling connection mutually.Compressor 46 is compressed air mechanically, and wherein air warms.When the air of relatively hot flow through heat radiation chamber 47, the air chamber 47 of will dispel the heat was heated to temperature apparently higher than local ambient temperature, made the chamber 47 of dispelling the heat heat can be distributed to environment.The heat that gathers is discharged by the extraneous air that flows through pipeline 26.Therefore, the extraneous air cooling heat dissipation chamber 47 of supply.By this way, from air stream 38, isolate heat.When and then air stream 38 flow through turbine 48, air stream drove turbine 48.Air stream 38 must be done mechanical power when driving turbine 48, make air stream be cooled to below the temperature of dew point.Therefore, cold air cooling condensation chamber 49 makes moisture with form condensation in condensation chamber 49 of water, and collects in the basin 43 accumulating in by pipeline 42, perhaps directly discharging to environment.When air stream 38 left condensation chamber 49, air stream was cold and dry.For heated air flow 38, be supplied to hot-zone 37 in the part of the heat of heat radiation chamber 47 inner accumulated, for example by two by pipeline 44 interconnective heat exchangers 45 and 52.Because the driving shaft of compressor 46 and turbine 48 is the mutual coupling connection mutually, thus turbine 48 drive compression machines 46, feasible only power P=P
K-P
TMust supply with compressor 46 from the outside, wherein measure P
KThe power that expression compressor 46 is required, and P
TThe power that expression turbine 48 provides.
Example 3
In the example shown in Figure 10, dehumidifying and cooling device 19 comprise compressor 46 and vortex tube 53.Compressor 46 compressed air flow 38, and therefore improve the pressure of air, make air stream 38 flow in the vortex tube 53 with big speed.At this, the temperature of air stream 38 increases.The part of heat sheds via pipeline 26 by means of heat exchanger 54.Vortex tube 53 is divided into thermal air current and cold air stream with air stream, and is designed to, and makes the temperature of cold air stream be lower than dew point, so that the moisture that contains at cold air stream is with the form condensation of water.Cold air stream and thermal air current guide the pipeline 50 or 51 that separates in, so one side can the condensation water outlet, and can for example isolate heat by means of another heat exchanger 55 from thermal current on the other hand.And then cold airflow and thermal current through dehumidifying merge before they leave dehumidifying and cooling device 19 once more.
