摘要： An air conditioner and a compressor protection circuit thereof are provided. When overcurrent occurs in a phase current of a compressor, an overcurrent level signal is output by a voltage comparison module, and is latched and output to an intelligent power module by a signal latching module, and the intelligent power module shuts off the output of the phase current according to the overcurrent level signal, so as to achieve the overcurrent protection of the compressor; and subsequently, a conventional level signal is output to the signal latching module by the voltage comparison module, the signal latching module keeps outputting the overcurrent level signal, and outputs the conventional level signal until a latching cancel signal output by a signal processing circuit is received, so that the intelligent power module starts the output of the phase current, thereby enabling the compressor to normally operate.

摘要： An air conditioner comprises a compressor to compress a refrigerant, a heat exchanger to move heat of the refrigerant, and a blower to blow air. The blower comprises a fan rotatable about a rotation axis, and a plurality of stationary blades installed to be a radial shape about the rotation axis in a direction in which the airflow generated by the rotation of the fan is discharged, and are curved in a direction opposite to the rotation direction of the fan from an inner circumferential portion to an outer circumferential portion. The stationary blades comprise an inlet edge, and an outlet edge, and an inlet angle formed by the inlet edge and the rotation axis and a chord angle formed by a chord connecting the inlet edge and the outlet edge and the rotation axis are larger at the inner and outer circumferential portions than at a radial center portion.

摘要： A residential HVAC system includes, a compressor, and an outdoor unit controller in communication with the compressor. The outdoor unit controller is configured to receive an indoor ambient temperature and a temperature set point. The outdoor unit controller is further configured to determine an outdoor ambient temperature, and to determine an operating value for the compressor based on a percentage of a delta between a minimum operating value of the compressor and a maximum operating value of the compressor, plus the minimum operating value. The minimum operating value and the maximum operating value are based on the determined outdoor ambient temperature. The percentage of the delta is based on a predefined temperature differential multiplier and one or more time dependent multipliers. The outdoor unit controller is further configured to modify the current operating value of the compressor with the determined operating value.

摘要： Frequency of a compressor is controlled so that an evaporating temperature reaches a target evaporating temperature during cooling operation, and, when refrigerant stagnation in a condenser of an outdoor unit is detected during cooling operation, a stagnation-resolving operation is implemented. The stagnation-resolving operation includes stagnation suppression control in which the target evaporating temperature is reduced within a range in which an evaporator does not freeze so as to increase a refrigerant circulation volume in the condenser, and stagnation-avoidance priority control which is implemented when implementation of the stagnation suppression control is not able to resolve stagnation, and in which an opening degree of an expansion valve is controlled to be opened and the target evaporating temperature is further reduced so as to further increase the refrigerant circulation volume.

摘要： Systems and methods are disclosed herein that include controlling operation of a heating, ventilation, and/or air conditioning (HVAC) system that utilizes information from a plurality of temperature sensors to monitor, verify, determine, and/or discover whether a temperature sensor is properly located in proximity to a dome of a compressor of the HVAC system. When the HVAC system determines that the temperature sensor associated with the dome of the compressor is not properly located, the HVAC system may initiate a shutdown of the compressor and/or other components of the HVAC system, generate a signal, present a message, and/or otherwise provide a notification of the improper temperature sensor placement, and/or reduce a runtime of the compressor, operate the compressor at a lower speed, reduce a power consumption of the compressor, and/or otherwise control the compressor and/or associated components to effectuate a reduced compressor dome temperature.
