摘要： A distributor (12) for an evaporator (22) in a vapor-compression circuit (10) comprises an elongate body (50A, 50B) defining an inlet portion (56A) and first and second distal ends (58A, 58B). The body (50A) being positionable along an interior sidewall (42) of the evaporator (22). The inlet portion (56A) positionable opposite an inlet port (38) of the evaporator (22) such that refrigerant entering the evaporator (22) engages the inlet portion (56A) of the distributor (12). The first and second distal ends (58A, 58B) extending outwardly towards opposing side ends (34A, 34B) of the evaporator (22). The elongate body (50A, 50B) cooperates with the sidewall (42) of the evaporator (22) to define a channel (49) having a generally uniform cross-sectional area extending from the first distal end (58A) to the second distal end (58B) such that refrigerant entering the channel (49) near the inlet portion (56A) is initially substantially contained between the sidewall (42) of the evaporator (22) and the elongate body (50A, 5OB). The elongate body (5OA, 50B) defining discharge ports (6OA, 6OB) to disperse refrigerant from the channel (49) into the evaporator (22).

摘要： A compressor arrangement includes two or more compressors (16a, 16b) arranged in a fluidly parallel configuration and a lubricant sump (38) containing a volume of lubricant operably connected to the two or more compressors. A lubricant sump pressure (P) is greater than a lubricant cavity pressure of each compressor (Pa, Pb, Pc) of the two or more compressors at all operating conditions of the two or more compressors. An equilibrium lubricant line (40) connects the lubricant sump to the two or more compressors to convey lubricant from the lubricant sump to a lubricant cavity (42) of each compressor of the two or more compressors.

摘要： A chiller system is provided including a vapor compression circuit consisting of a fluidly coupled compressor, condenser, expansion valve, and evaporator. A refrigerant circulates through the vapor compression circuit. The evaporator is a direct exchange heat exchanger. Refrigerant provided at an outlet of the evaporator is a two-phase mixture including liquid refrigerant and vapor refrigerant. The vapor refrigerant comprises less than or equal to 85% of the two-phase mixture. A refrigerant to refrigerant heat exchanger is fluidly coupled to the circuit. The refrigerant to refrigerant heat exchanger is configured to convert the vapor refrigerant provided at the outlet of the evaporator into a superheated vapor.
