摘要： Disclosed in the present invention are a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises a cold accumulation tank, and a condensation tank accommodating the cold accumulation tank. The cold accumulation tank stores a quantity of cold by means of a cold accumulation material. The condensation tank is used for separating a gas mixture of gaseous refrigerant and non-condensable gas exiting the system into liquid refrigerant and non-condensable gas, by causing the gas mixture of gaseous refrigerant and non-condensable gas to undergo heat exchange with the cold accumulation material in the cold accumulation tank; the isolated liquid refrigerant is led into the system, and the isolated non-condensable gas is discharged from the condensation tank. The method comprises a cold accumulation process, a condensation process, a gas discharge process and a liquid discharge process.

摘要： A condenser unit for a chiller assembly is provided. The condenser unit includes a shell having a substantially cylindrical shape, a first tube bundle disposed within the shell, and an inlet pipe and an outlet pipe coupled with the shell. The inlet pipe receives vapor refrigerant and the outlet pipe discharges liquid refrigerant. The inlet includes a substantially straight portion having a first diameter and a flared lip portion having a second diameter. The second diameter is larger than the first diameter. The condenser unit further includes a baffle disposed below the flared lip portion and above the first tube bundle. The baffle obstructs refrigerant entering the shell from falling directly on the first tube bundle and has a substantially plate-like geometry.

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.

The flooded evaporator (68) includes a liquid distributor (104) disposed within the interior volume (264) of the shell (102) and configured to receive the two-phase refrigerant (106) from the refrigerant inlet (110). The liquid distributor (104) includes a main body (160, 162) coupled to a bottom portion (114) of the shell and separating the interior volume (264) of the shell into a distributor volume (222) and a remaining volume (262). The liquid distributor (104) also includes a refrigerant passage (352) formed in the main body (160, 162) and fluidly coupling the distributor volume (222) and the remaining volume (262). The refrigerant passage (352) includes a first portion and second portion, the first portion includes a first cross-sectional area greater than a second cross-sectional area of the second portion, and the first portion is closer to the refrigerant inlet (110) than the second portion.
