Abstract
An HVAC system includes a dehumidifier having an evaporator, a condenser, a compressor, and an expansion device. The dehumidifier is disposed in at least one of a main supply duct, a main return duct, and an indoor unit of the HVAC system. The dehumidifier comprises no application specific air moving device, as the airflow through the dehumidifier is generated solely by an indoor fan disposed in the indoor unit of the HVAC system such that all of the airflow through an air circulation path of the HVAC system passes through the dehumidifier, regardless of whether the dehumidifier is being operated to dehumidify or provide humidity to the airflow.
Claims20
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- an indoor unit comprising a blower configured to generate an airflow;
- and
- a dehumidifier;
- wherein the entirety of the airflow generated by the blower passes through the dehumidifier.
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- an indoor unit comprising a blower configured to generate an airflow;
- and
- a dehumidifier comprising an evaporator and a condenser;
- wherein at least a portion of the airflow passes through the evaporator of the dehumidifier, and wherein the entirety of the airflow passes through the condenser of the dehumidifier.
A method of operating a heating, ventilation, and/or air-conditioning (HVAC) system, comprising:
- providing an indoor unit and a dehumidifier in an HVAC system;
- monitoring the humidity of a zone conditioned by the HVAC system;
- generating an airflow via a blower of the indoor unit;
- passing the entirety of the airflow through the dehumidifier;
- reducing the humidity of the airflow;
- and
- delivering the reduced humidity airflow to at least one zone conditioned by the HVAC system.
