20120085113 | FAN MOTOR CONTROLLER FOR USE IN AN AIR CONDITIONING SYSTEM - One aspect of the disclosure provides an air conditioning system. The air conditioning system, in this embodiment, includes an exterior housing, and a motor having fan blades rotatably coupled thereto located within the exterior housing. The air conditioning system, in this embodiment, further includes a controller coupled to the motor and configured to rotate the fan blades based upon climate conditions proximate the exterior housing. | 04-12-2012 |
20140150479 | Secondary Defrost for Heat Pumps - Frost may accumulate on a heat pump. In various implementations, a primary defrost operation and/or a secondary defrost operation may be utilized to remove at least a portion of the frost from the heat pump. | 06-05-2014 |
20150047375 | DEFROST OPERATION MANAGEMENT IN HEAT PUMPS - In various implementations, a heat pump may include heating operations and defrost operations. The heat pump may monitor cycle time(s) for one or more of the operations. Defrost operation(s) in the heat pump may be automatically adjusted based at least partially on cycle times. | 02-19-2015 |
20150260458 | Adjustable Multi-Pass Heat Exchanger - In various implementations, an air conditioner may include a heat exchanger having one or more flow paths. At least one of the flow paths may be associated with more than one pass and/or fluid flow through the flow path may be restricted. A setting of the heat exchanger may include associations between flow path(s) and/or pass(es). A setting for the heat exchanger may be determined and the heat exchanger may be allowed to operate in the determined setting, in some implementations. | 09-17-2015 |
20150300744 | Adjustable Multi-Pass Heat Exchanger System - In various implementations, a heat exchanger system may include one or more flow paths. At least one of the flow paths may be associated with more than one pass and/or fluid flow through the flow path may be restricted. A setting of the heat exchanger system may include associations between flow path(s) and/or pass(es). A setting for the heat exchanger system may be determined, and the heat exchanger system may be allowed to operate in the determined setting, in some implementations. | 10-22-2015 |
20150330684 | LIQUID LINE CHARGE COMPENSATOR - An apparatus and method for reducing discharge pressure in a Heating, Ventilating, and Air Conditioning system. The apparatus has a compensator reservoir and a compensator line. The compensator line connects the compensator reservoir and a liquid line. The liquid line connects a condenser and an evaporator. The compensator line has a connection to the compensator reservoir and a connection to the liquid line. In the method, a controller checks for one or more conditions indicating a likelihood of high discharge pressure. The controller finds a condition indicating a likelihood of high discharge pressure. In response to finding the condition, the controller closes a compensator valve after a set amount of time. The controller reopens the compensator valve. | 11-19-2015 |
20150330688 | COMPRESSOR OPERATION MANAGEMENT IN AIR CONDITIONERS - In various implementations, compressor operation in an air conditioner may be managed by maintaining oil viscosity, a temperature differential, compressor sump temperature, and/or suction pressure. Properties of the air conditioner or portions thereof, such as the compressor, may be determined. To manage compressor operations, operation(s) of the air conditioner may be adjusted based on one or more of the determined properties. | 11-19-2015 |
20150362204 | HVAC SYSTEMS AND METHODS WITH REFRIGERANT LEAK DETECTION - Systems and methods are disclosed that involve detecting a flammable refrigerant associated with a heating, ventilating, and air conditioning (HVAC) system. In one instance a damper covers an access port allowing a single sensor to monitor at least two separate spaces. In another instance, a multi-probe sensor allows a single sensor to monitor at least two separate spaces. Other systems and methods are presented. | 12-17-2015 |
