摘要： A refrigerant system adapted to reduce refrigerant migration therein includes a compressor and a controller. The compressor has a motor with motor windings. The motor windings are responsive to control signals to selectively generate heat in a manner that does not turn the motor. The controller selectively energizes the motor windings to generate heat based on at least one of a monitored temperature or pressure to warm the compressor.

摘要： A method to detect and respond to a coil condition in an HVAC system. The method includes calculating an initial airflow restriction value and a current airflow restriction value, which are compared. If the current airflow restriction value is greater than a first sum including the initial airflow restriction value and a first restriction factor, then a coil condition is preliminarily determined to be freezing and cooling in the HVAC system is stopped.

摘要： An air conditioning system that comprises a controller that is in electrical communication with a compressor, a condenser fan, a temperature sensor that measures the temperature of the ambient air, a temperature sensor that measures the temperature of a condenser coil of the air conditioning system, and a low pressure switch (LPS) that measure the pressure of a refrigerant disposed within the air conditioning system. An algorithm resident on the controller controls the controller to enter a low ambient cooling mode when the temperature of the ambient air is less than a set temperature. The algorithm further controls the controller so that a minimum and/or maximum cycling frequency is imposed on the condenser fan. The algorithm further controls the controller so that the controller does not respond to an LPS trip during the early part of a cooling cycle under low outdoor temperature conditions, which might not accurately indicate a system fault, but still shuts down the compressor in response to an LPS trip under conditions that truly indicate a system fault.

摘要： A zoned HVAC system is provided with a series of dampers. A control for the dampers causes the dampers to each move between open and closed positions while monitoring a system condition. The system condition is selected to be one that should change as the damper moves between open and closed positions. If the system condition does not change as the control orders the damper to move between the open and closed positions, the particular damper is identified as a potentially faulty damper.

摘要： An expandable media filter structure is composed largely of biodegradable materials and is environmentally disposable. A plurality of pleated panels are interconnected at their edges so as to be collapsible for storage and shipping purposes but expandable for installation and use. A plurality of ribbons are ultrasonically welded to each of the panel edges, wit the ribbon portions between edges being of substantially equal lengths, thereby maintaining equal spacing between the panel edges when the filter is in the expanded condition but allowing an easy collapsing of the filter for storage. Forming a part of the disposable filter are pair of end plates, with each being adhesively attached to an end panel and having a pair of slots formed near their ends for attachment to a nondisposable support structure. The end panels are formed of multiple layers of paperboard which are adhesively bonded and compressed into a U-shaped structure that rigidly supports the filter in its expanded condition. The nondisposable support structure includes a pair of molded plastic side caps that fit over the respective ends of the filter panels and the end plates. Each side cap has a pair of flanges at its opposite ends which act to maintain the filter in its expanded condition when the end plates are placed in abutting position therewith. Each side cap also includes a boss which fits into a respective end plate slot to hold the end plates in their installed positions within the side caps.

摘要： An apparatus and method for a heat pump operating in the heating mode controls the condenser air flow rate and the condenser exiting air temperature depending in a first embodiment on the evaporator ambient temperature, and in a second embodiment, the evaporator air temperature and alternatively the condenser air flow rate or the condenser exiting air temperature, to alleviate a cold blow condition. The apparatus and method operate by sensing the evaporator ambient temperature with a sensor positioned proximate to the evaporator, and when that temperature is below a threshold value indicating a cold blow situation, determining by circuit means a modified condenser air flow rate to achieve at the same time a slower air flow and a higher air temperature, so that the cold blow condition is terminated or at least alleviated. The apparatus and method alternatively command the blower to achieve a determined condenser air flow, or to achieve a determined blower speed depending upon motor type, that results in a targeted condenser air flow or a targeted condenser exiting air temperature.
