Abstract
The invention relates to a process for the cooling and conditioning of air heated in a process, in particular of machine exhaust air which is cooled through heat exchange by means of a cooling medium, whereby water is preferably used as the cooling medium. It is provided that open waters, well and/or tap water of the water supply network are used for the heat exchange, whereby this water is used after utilization in the heat exchange at other locations for the cooling of the process and/or as hot water for further utilization in the process.
Claims18
A method for cooling and conditioning heated waste air generated in a textile room from textile machines carrying out a textile process, said process comprising:
- drawing the heated waste air from the textile room and passing the air through a liquid medium heat exchanger;
- drawing a liquid cooling medium at a desired temperature from a constant source and passing the liquid cooling medium through the heat exchanger to cool the heated waste air, the liquid cooling medium thereby being heated by the heated waste air;
- recycling at least a portion of the cooled air exiting the heat exchanger back to the textile room;
- and
- directing the heated liquid cooling medium from the heat exchanger to an operative location in the textile process requiring a separate medium of approximately the temperature of the heated liquid cooling medium, and using the heated liquid cooling medium at the location as a source of the separate medium to reduce the overall energy consumption of the textile process.
A method for cooling and conditioning air in a textile room having any number of textile machines generating heated waste air, said method comprising:
- directly exhausting at least a portion of the heated waste air directly to the outside and drawing at least another portion of the heated waste air through a liquid cooling medium heat exchanger;
- drawing a liquid cooling medium at a desired temperature from a constant source and passing the liquid cooling medium through the heat exchanger to cool the heated waste air, the liquid cooling medium thereby being heated by the heated waste air;
- passing at least a portion of the cooled air exiting the heat exchanger through a spray humidification device to further cool and humidify the air;
- admixing air from another source with the cooled air exiting the spray humidification device and returning the admixed air to the textile room;
- directing the heated liquid cooling medium to the roof of the textile room;
- and
- spaying down the roof of the textile room with the heated liquid cooling medium to cool the air in the textile room below thereby reducing the load on the heat exchanger and spray humidification device.
