摘要： A condenser includes a refrigerant inlet having an inlet pipe traversing from an outside of the shell to the interior space. The inlet pipe includes an inlet pipe inner diameter. Additionally, the refrigerant inlet includes a bell mouth tapered outward from the inlet pipe and into the interior space of the shell. The condenser also includes a refrigerant inlet baffle configured to distribute a low pressure refrigerant gas along a portion of an interior length of a shell of the condenser. An upper surface of the refrigerant inlet baffle is vertically spaced from a bottom edge of the bell mouth by an upper layout height. Additionally, a bottom surface of the refrigerant inlet baffle is vertically spaced from a bottom inner surface of the shell by a lower layout height. The upper layout height is greater than 0.25 of the inlet pipe inner diameter.

摘要： A chiller (22) includes an evaporator (46), a compressor (48) including a prime mover (84), a first pressure sensor (86) that detects a first pressure in the evaporator (46), a second pressure sensor (88) that detects a second pressure in a condenser (50), and a controller (100). The controller (100) determines a predicted energy level of the compressor (48) based on the first pressure and the second pressure, the predicted energy level associated with liquid droplet flow into the compressor (48), compares the predicted energy level to an operating energy level, and modifies the at least one of the input power and the input current to the prime mover (84) based on the comparison satisfying a modification condition.

摘要： A condenser unit (300) for a chiller assembly is provided. The condenser unit (300) includes a shell (302) having a substantially cylindrical shape, a first tube bundle disposed within the shell(302), and an inlet (304) and an outlet (306) coupled to the shell (302). The inlet (304) is configured to receive vapor refrigerant and the outlet (306) is configured to discharge liquid refrigerant. The inlet (304) includes a substantially straight pipe terminating at a flared lip (308). The flared lip (308) is configured to increase a vapor refrigerant flow path of the inlet from a first cross-sectional area to a second cross-sectional area. The increase from the first cross-sectional area to the second cross-sectional area causes a portion of kinetic energy of the vapor refrigerant to be converted into pressure energy.

摘要： The present disclosure provides a gas discharge apparatus, a refrigerating and air-conditioning unit, and a method of discharging a non-condensable gas. The gas discharge apparatus comprises a gas discharge compressor and a heat exchanger, wherein a gas suction port of the gas discharge compressor is connected to a condenser of the refrigerating and air-conditioning unit to introduce a mixed gas comprising a gaseous refrigerant and a non-condensable gas into the gas discharge compressor to be compressed; a gas inlet of the heat exchanger is connected to a gas discharge port of the gas discharge compressor; a liquid outlet of the heat exchanger is connected to an evaporator or the condenser of the refrigerating and air-conditioning unit; the heat exchanger further has a cold source inlet and a cold source outlet available for the cold source to flow through, such that the compressed mixed gas enters the heat exchanger to exchange heat with the cold source and the gaseous refrigerant is condensed into a liquid refrigerant which is discharged into the evaporator or condenser, and a gas outlet is configured to discharge the separated non-condensable gas from the heat exchanger. The gas discharge apparatus according to the present disclosure may effectively separate and discharge the non-condensable gas in the refrigerating and air-conditioning unit, thereby guaranteeing its safe and efficient operation.
