Desiccant assisted multi-use air pre-conditioner unit with system heat recovery capability

Abstract

A dehumidifier unit for pre-conditioning air delivered to a multiplicity of separate refrigeration air conditioner units and especially ductless systems where the compressor-condenser unit is separate from the fan-coil unit, and assisted by heat pipe transfer of heat from air dehumidified through a desiccant wheel and by heat of compression from the condenser of one compressor-condenser unit, and with a heater to maintain the temperature of regeneration air through the wheel, one dehumidifier unit pre-conditioning air for a multiplicity of refrigeration air conditioners or fan-coil units.

Description

PREFERRED EMBODIMENTThis invention relates to a versatile multi-use stand-alone dehumidifier unit adapted to pre-condition air in conjunction with, but not necessarily with refrigeration systems, whereby optimum humidity is attained in differing climatic conditions, waste heat being used when available for efficiency in the operation of both the dehumidification means and the refrigeration air conditioning means when combined therewith. Humidity has its effect upon building construction, as high humidity reduces the presence of mold and mildew, and can be controlled to levels which contribute to the elimination of bacteria propagating environments, For example, refrigeration air conditioner systems in humid environments are often inadequate with respect to acceptable humidity control, with or without refrigeration incorporated therein. And, in wet environments refrigeration air conditioner systems utilizing refrigerant cooled air coils are often overtaxed and their efficiency advers...

AI Technical Summary

Benefits of technology

The inventive concept herein disclosed provides a versatile air pre-conditioner that is adapted to be implemented in various configurations as a stand-alone unit, in that it is self sufficient, if need be, to humidify or dehumidify incoming air. Outside air and/or return air from conditioned space is processed, with or without refrigeration, to be dehumidified in hot-wet climate, and humidified in cold-dry climate conditions. The structural configuration of this air pre-conditioner can vary widely, as to size, shape and disposition of the ducting means therein, and characterized by two dedicated ducting means, and at least one additional ducting means that processes waste heat from
