Abstract: A heat exchanger for receiving an airflow having an uneven intensity distribution across the heat exchanger and for flowing refrigerant within the heat exchanger. The heat exchanger includes sections of microchannel tubes for flowing refrigerant through at least one pass through the heat exchanger, wherein the sections are configured according to the airflow across the heat exchanger. The heat exchanger may be used in an HVAC system. A method may also be performed to manufacture the heat exchanger.

Abstract: A control system for a HVAC system for a structure and comprising a blower that flows air over an indoor heat exchanger. The control system may include a first input device, a first sensor, and a processor in electronic communication with the first input device, the first sensor, and the blower of the HVAC system. The first input device may be operable to accept a zoning mode selection. The first sensor may be sensor operable to measure a first temperature at a first location within the structure. The processor may be programmed to determine a cooling or heating demand on the HVAC system based on an input temperature and the first measured temperature. The processor may be further programmed to adjust an air flow rate produced by the blower based on the demand on the HVAC system and the zoning mode selection.

Abstract: A heating, ventilation, and air-conditioning ("HVAC") system for use with a refrigerant. The HVAC system includes a compressor, a condenser, an evaporator expansion device, and an evaporator. The HVAC system also includes a thermal energy storage device ("TESD") including thermal energy storage media in line between the condenser and evaporator. A control system is programmed to operate the compressor and the evaporator expansion device to control the refrigerant flow through the HVAC system. The control system is also programmed to control the refrigerant flow through the TESD to charge the TESD with thermal energy. The control system is also programmed to control the refrigerant flow through the evaporator expansion device and evaporator and discharge the thermal energy from the charged TESD to improve the performance of the HVAC system.

Abstract: A dehumidification system for use with a dehumidification refrigerant to dry ambient air as part of a heating, ventilation, and air-conditioning ("HVAC") system that includes an HVAC condenser as part of an HVAC refrigeration circuit. The dehumidification system may include a dehumidification refrigeration circuit separate from the HVAC refrigeration circuit. The dehumidification circuit may include a dehumidification compressor, a dehumidification condenser, a dehumidification expansion device, and a dehumidification evaporator. The dehumidification condenser may be positioned in close proximity to the HVAC condenser such that airflow across the HVAC condenser also flows across the dehumidification condenser. The dehumidification evaporator may be spaced apart from the dehumidification condenser such that airflow across the dehumidification evaporator does not flow across the dehumidification condenser.
