Abstract: A method for determining a mass flow of a dynamic compressor that does not include a mass flow sensor while the compressor is operating to compress a working fluid includes determining, by a processor, a current operating point of the compressor. If the current operating point is the same as one in a map of a plurality of predetermined operating points stored in a memory, the mass flow of that predetermined operating point is retrieved as the mass flow of the current operating point. Otherwise, the processor calculates the mass flow at the current operating point from the mass flows of a subset of the predetermined operating points nearest the current operating point. The dynamic compressor continues to operate to compress the working fluid based at least in part on the calculated mass flow rate for the current operating point.

Abstract: A heat-pump system may include an outdoor heat exchanger, an expansion device, an indoor heat exchanger, a compressor, and a multiway valve. The expansion device is in fluid communication with the outdoor heat exchanger. The indoor heat exchanger is in fluid communication with the expansion device. The compressor circulates working fluid through the indoor and outdoor heat exchangers. The multiway valve may be movable between a first position corresponding to a cooling mode of the heat-pump system and a second position corresponding to a heating mode of the heat-pump system. The working fluid flows in the same direction through the outdoor heat exchanger in the cooling mode and in the heating mode, and the working fluid flows in the same direction through the indoor heat exchanger in the cooling mode and in the heating mode.

Abstract: A compressor may include first and second scrolls, a hub plate and a valve member. The first scroll includes an end plate having a primary discharge passage and a secondary discharge passage. The secondary discharge passage is disposed radially outward from the primary discharge passage. The hub plate is mounted to the first scroll and has a hub discharge passage extending therethrough. The hub discharge passage is in fluid communication with the primary discharge passage. The valve member is movable between open and closed positions. The valve member restricts fluid flow through the secondary discharge passage when in the closed position to restrict fluid communication between the secondary discharge passage and the hub discharge passage. The valve member allows fluid flow through from the secondary discharge passage when in the open position to allow fluid communication between the secondary discharge passage and the hub discharge passage.

Abstract: First and second IAQ sensors are located within a building and are configured to measure first and second IAQ parameters, respectively, the first and second IAQ parameter being the same one of: relative humidity; amount of particulate; amount of volatile organic compounds; and amount of carbon dioxide. A mitigation device is separate from an HVAC system and includes a control module configured to turn the mitigation device on and off based on the first IAQ parameter, the second IAQ parameter, and whether the HVAC system is on or off. A mitigation module is configured to selectively turn the HVAC system on and off based on the second IAQ parameter, the first IAQ parameter, and whether the HVAC system is on or off.

Abstract: A compressor includes a shell, a muffler plate, first and second scroll members, and first and second sealing members. The shell defines first and second pressure regions separated by the muffler plate. The first scroll member includes a first end plate and a first scroll wrap. The first end plate defines an annular recess and a discharge recess. The discharge recess is in communication with the first pressure region. The second scroll member includes a second end plate and a second scroll wrap. The second scroll wrap meshingly engages the first scroll wrap to define a compression chamber therebetween. The first sealing member is at least partially disposed in the discharge passage and fluidly separates the first and second pressure regions from each other. The second sealing member is at least partially disposed in the annular recess.

Abstract: A climate-control system may include a first fluid circuit, a desiccant system, and a second fluid circuit. The first fluid circuit may include a desorber, an absorber, and an evaporator. A first fluid exits the desorber through a first outlet and flows through the evaporator and a first inlet of the absorber. A second fluid exits the desorber through a second outlet and may flow through a second inlet of the absorber. The desiccant system includes a conditioner and a regenerator. The conditioner includes a first desiccant flow path. The regenerator includes a second desiccant flow path in communication with the first desiccant flow path. The second fluid circuit circulates a third fluid that is fluidly isolated from the first and second fluids and desiccant in the desiccant system. The second fluid circuit may be in heat transfer relationships with the first fluid and the first desiccant flow path.

Abstract: A system includes a heat-pump circuit and a heating-fluid circuit. The heat-pump circuit includes a compressor and a first condenser conduit. The heating-fluid circuit includes first, second, and third flow-paths. The third flow-path selectively communicates with the first and second flow-paths. The first flow-path includes a first valve. The first valve moves between an open position allowing fluid flow through the first flow-path and a closed position restricting fluid flow through the first flow-path. The second flow-path includes a second condenser conduit and a second valve. When the second valve is open, fluid flows through the second flow-path. In the closed position, the second valve restricts fluid flow through the second flow-path. The third flow-path includes a heat exchanger receiving fluid from the first flow-path when the first valve is in the open position and receiving fluid from the second flow-path when the second valve is in the open position.

Abstract: A heating, ventilation, and air conditioning system includes first and second fluids, a heat exchanger, a refrigerant sub-system, and at least one closed loop sub-system. The heat exchanger includes a membrane for channeling the first fluid through the heat exchanger and is disposed for heat transfer between the first fluid and the second fluid. The membrane defines an inlet having an inlet height relative to grade. The closed loop sub-system transfers heat from the heat exchanger to the refrigerant sub-system and includes an expansion tank containing the first fluid. A level of the first fluid within the expansion tank has a level height relative to grade. The expansion tank is positioned relative to the heat exchanger such that the inlet height is greater than the level height and the membrane is maintained in a collapsed configuration.

Abstract: An HVAC system includes an unloading device, a centrifugal compressor, a gas foil bearing, a VFD and a controller. The controller is programmed to start the centrifugal compressor from a stopped condition by operating the unloading device to remove a load from the centrifugal compressor, accelerating the motor to a first speed above a liftoff speed of the gas foil bearing and below an operating speed of the centrifugal compressor, running the motor for a period of time, operating the unloading device to apply the load to the centrifugal compressor, and accelerating the motor to the operating speed.
