    摘要： A refrigeration system configured for controlling operation of a compressor is disclosed. The refrigeration system comprises an electronic expansion device operatively coupled with the compressor. The refrigeration system comprises a controller operatively coupled with the electronic expansion device. The controller is configured to control the electronic expansion valve based on a superheat setpoint range. The controller is further configured to adjust the superheat setpoint range in response to an operating point of the compressor being within a threshold distance from a boundary of an operational envelope for the compressor.

    摘要： A refrigerant detection assembly for detecting moderate-to-low GWP value refrigerants, an air conditioning system for incorporating the same, and a method of detecting refrigerant leaks using the refrigerant detection assembly are provided. The refrigerant detection assembly may be disposed proximate to an indoor heat exchanger. The refrigerant detection assembly includes a nondispersive infrared (NDIR) sensor, a fan disposed adjacent to the nondispersive infrared sensor, the fan configured to direct a sample to the nondispersive infrared sensor, and a controller operatively connected to the nondispersive infrared sensor and the fan. The controller is configured to operate the fan in constant operation and trigger a response when the refrigerant detection assembly detects at least 25% lower flammability limit (LWL) in the sample.

    摘要： A contactor, and an air conditioning system incorporating the contactor are provided. The contactor includes a body with an upper surface, a line-side electrical terminal located on one end of the body, a load-side electrical terminal located on the other side of the body, a switching element within the body, the switching element coupled between the line-side electrical terminal and the load-side electrical terminal, and a refrigerant mitigating element disposed on the upper surface. The line-side electrical terminal is configured to receive electrical power from an electrical grid. The load-side electrical terminal is configured to transfer at least a portion of the electrical power to at least one component of the outdoor unit. The switching element is configured to electrically connect the line-side electrical terminal and the load-side electrical terminal when activated. The refrigerant mitigating element may help mitigate the ignition of a refrigerant.

    摘要： A method for diluting a leaked refrigerant in a refrigeration system according to an example of the present disclosure includes operating the refrigeration system in a purge mode based on at least one purge condition prior to initiating a compressor of the refrigeration system. A refrigeration system according to an example of the present disclosure includes a compressor configured to compress refrigerant in a refrigerant line, a heat exchanger configured to exchange heat with the refrigerant line in a heat exchange mode, a fan configured to pass air through the heat exchanger to an indoor space, and a controller configured to operate the refrigeration system in a purge mode based on at least one purge condition prior to initiating the compressor.

    摘要： An ejector has: a motive flow inlet (40); a secondary flow inlet (42); an outlet (44); a motive flow nozzle (242) having an outlet (110); a primary flowpath from the motive flow inlet through the motive flow nozzle to the ejector outlet; a secondary flowpath from the secondary flow inlet to the ejector outlet, merging with the primary flowpath at the motive nozzle outlet; a control needle (200; 300; 400) shiftable along a range of motion between a first condition and a second condition and seated against the motive nozzle in the second condition. The needle comprises: a main shaft (210); a tip (204); a first portion (220; 320) converging toward the tip; and a shoulder portion (214; 314; 422) between the first portion and the main shaft and seated against the motive nozzle in the second condition and converging toward the tip at a greater angle (?1; ?1 2) than an angle (?2; ?2 2) of the first portion.

    摘要： Disclosed is an air conditioning system having: a first HVAC assembly comprising an indoor heat exchanger and a fan; a first sensor, configured to sense a first temperature reading, operably coupled to the indoor heat exchanger; a second sensor, configured to sense a second temperature reading, positioned downstream of the first sensor and detached from the indoor heat exchanger; and a system controller configured to activate the fan to deliver airflow across the indoor heat exchanger when the difference between the first temperature reading and the second temperature reading is greater than or equal to a predetermined threshold, the temperate differing being checked when the first HVAC assembly is in an inactive mode and the fan and a compressor operably connected to the first HVAC assembly are in an inactive mode.
