摘要： A heat exchanger includes a plurality of conduits that extend between a first endplate and a second endplate. A first manifold is coupled to the first endplate to couple the first manifold to first ends of the plurality of conduits. An inlet is coupled to the first manifold to direct a first fluid into the first manifold and at least one baffle is disposed within the first manifold to form a first cavity and a second cavity. The at least one baffle of the first manifold is configured to direct the first fluid from the inlet to a first conduit of the plurality of conduits. A second manifold is coupled to the second endplate to couple the second manifold to second ends of the plurality of conduits and at least one baffle is disposed within the second manifold to form a fourth cavity and a fifth cavity.

摘要： A method of protecting a single-stage furnace in a multi-zone system includes monitoring a temperature of each zone of a plurality of zones, determining if the temperature of at least one zone of the plurality of zones is less than a threshold temperature, powering on the HVAC system to satisfy a heating demand of the zone having a temperature less than the threshold temperature, monitoring an outlet temperature of the single-stage furnace, determining if the outlet temperature is greater than an outlet temperature threshold, and responsive to a determination that the outlet temperature is greater than the outlet temperature threshold, modulating a gas valve to reduce a flow of gas to the single-stage furnace.

摘要： A method of initiating a low-energy cooling mode using a controller of an HVAC system includes measuring a temperature of ambient air proximal to a condenser coil and determining whether the temperature of the ambient air proximal the condenser coil is less than a temperature threshold. If the temperature of the ambient air is less than the temperature threshold, the HVAC system is configured to operate in a low-energy cooling mode. In the low-energy cooling mode, the controller opens a first bypass valve to allow a refrigerant to bypass a compressor and the compressor is powered off. The HVAC system is operated until a cooling demand has been met.

摘要： An apparatus that includes a refrigeration circuit that includes an evaporator, a first condenser and a compressor. The apparatus includes a refrigerant-water heat exchanger that includes a second condenser fluidly coupled to the refrigeration circuit. A control valve is operatively connected to the refrigeration circuit to direct flow of refrigerant through at least one of the first condenser during a dehumidification mode and the second condenser during a water heating mode. A damper is disposed on an upwind side of the evaporator, the damper being operable to reduce airflow across the evaporator during a ventilation mode.

摘要： Systems, devices, and methods are presented for using a liquid desiccant to regulate a moisture content of air conditioned by a heating, ventilating, and air conditioning (HVAC) system. The liquid desiccant is disposed within a processing volume, which is substantially-enclosed and substantially segregates the liquid desiccant from the conditioned air. A pair of vapor-permeable membranes define opposite surfaces of the processing volume. Water vapor diffuses through the vapor-permeable membranes, thereby enabling an exchange of moisture between the liquid desiccant and the conditioned air. The refrigerant circuit itself is used to cool desiccant in the absorber and heat desiccant in the desorber. Other systems, devices, and methods are presented.
