Abstract
A process for open-cycle air conditioning which affords economy of external power both with respect to cost and energy consumption by providing a low-temperature heater and a high-temperature heater for regenerating the sensible heat exchanger and desiccant when the apparatus is used for cooling and the enthalpy exchanger when the apparatus is used for heating. The power source for the low-temperature heater can utilize solar energy, waste boiler heat, waste process heat, nuclear reactor heat and the like. The power source for the high-temperature heater can be an open flame burner or other conventional heater.
Claims9
An open-cycle air conditioning process for cooling air wherein air to be cooled is passed through a treatment passageway and a regeneration air stream is passed through a separate regenerative air passageway comprising the steps:
- passing air to be cooled through a treatment air passageway and in sequence adiabatically drying the treatment stream by a desiccant means, transferring sensible heat resulting from the adiabatic drying by a sensible heat exchanger means for the treatment air stream to the regeneration air stream and evaporatively cooling the treatment air stream with water to provide conditioned air having desired temperature and humidity;
- and
- passing a regeneration air stream through a separate regeneration air passageway countercurrent to said treatment air stream and in sequence regenerating said sensible heat exchanger means by absorbing heat in the regenerative air stream, the entire regenerative air stream from said heat exchanger means being further heated by passing a low temperature heater means between said sensible heat exchanger means and said desiccant means supplying heat to the entire regenerative air stream, splitting said regenerative air stream into a first and a second portion, said first portion passing directly through a segment of said desiccant means to partially regenerate said segment and said second portion being further heated by passing a high temperature heater means and than passing said second portion through the segment of said desiccant means partially regenerated by said first stream at a sufficient temperature to complete regeneration of said desiccant means segment.
