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.
Claims26
A convertible desiccant assisted air pre-conditioner for implemented use to dehumidify an air column delivered into an air conditioned space, and including;
- a first ducting means dedicated to dehumidification of incoming air at an intake end and delivering supply air at a discharge end for conditioning said air conditioned space,
- a second ducting means dedicated to desiccant regeneration by means of return air from said air conditioned space,
- there being at least one air flow control means at an intake end of the second ducting means,
- a third ducting means for receiving return air at an intake end and delivering exhaust air at a discharge end,
- there being one air flow control means space at the intake end of the third ducting means and at least one air flow control means space at the discharge end of the third ducting means,
- a coupler means duct open between the at least one air flow control means at an intake end of the second ducting means and said one flow control means space at the intake end of the third ducting means,
- desiccant dehumidifying means exposed to an air column flowing through the first ducting means for dehumidification and exposed to an air column flowing through the second ducting means for regeneration of weakened desiccant,
- heater means for tempering the air column to a regenerating temperature through the second ducting means,
- and heat transfer means exposed to air columns flowing through each of said first and third ducting means.
A desiccant assisted air pre-conditioner implemented to pre-condition outside air delivered to a multiplicity of refrigeration air conditioner units and each of which is comprised of a refrigerant compressor, a refrigerant condenser for removal of heat of compression, a thermal expansion valve and refrigeration coil with refrigerant return to the compressor, the air pre-conditioner including;
- a first ducting means dedicated to dehumidification of incoming outside air with discharge ducting to each of said multiplicity of refrigeration air conditioner units,
- a second ducting means dedicated to desiccant regeneration by means of return air therethrough to exhausting from the air space conditioned by said multiplicity of refrigeration conditioner units,
- a third ducting means for receiving said return air and delivering it to said second ducting means,
- a desiccant dehumidifying means exposed into the first ducting means for dehumidifying the air flow therethrough and exposed into the second ducting means for regeneration of weakened desiccant,
- a heat transfer means exposed to the air flow from the dehumidifying means exposed into said first ducting means to absorb heat and exposed into the air flow through the third ducting means to dissipate heat into the air flow therethrough,
- a substantial portion of said refrigerant condenser of one of said multiplicity of refrigeration air conditioner units being exposed in the second ducting means for dissipating heat of compression to the regeneration air flow therethrough,
- and a heater means exposed in the second ducting means for supplementing said heat transfer means heat dissipation and said heat of compression condenser portion dissipation to maintain regeneration temperature.

- a first ducting means dedicated to dehumidification of incoming outside air with discharge ducting to each of said multiplicity of fan-coil units,
- a second ducting means dedicated to desiccant regeneration by means of return air therethrough and to exhausting from the air space conditioned by said multiplicity of fan-coil units,
- a third ducting means for receiving said return air and delivering it to said second ducting means,
- a desiccant dehumidifying means exposed into the first ducting means for dehumidifying the air flow therethrough and exposed into the second ducting means for regeneration of weakened desiccant,
- a heat transfer means exposed to the air flow from the dehumidifying means exposed into said first ducting means to absorb heat and exposed into the air flow through the third ducting means to dissipate heat into the air flow therethrough,
- a substantial portion of said refrigerant condenser of one of said multiplicity of compressor units being exposed in the second ducting means for dissipating heat of compression to the regeneration therethrough,
- and heater means exposed in the second ducting means for supplementing said heat transfer means heat dissipation and said heat of compression condenser portion dissipation to maintain regeneration temperature.
