Abstract:
Embodiments of the present disclosure relate to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system (10) that includes a refrigerant loop (100), a compressor (32) disposed along the refrigerant loop and configured to circulate refrigerant through the refrigerant loop, and an evaporator (38) disposed along the refrigerant loop and configured to place the refrigerant in thermal communication with a cooling fluid, where the refrigerant (126) surrounds a tube bundle (110) disposed in the evaporator, the tube bundle is configured to flow the cooling fluid, and the evaporator (38) has a height (102) based at least on a target height of a liquid level (108) of refrigerant in the evaporator, the evaporator includes a discharge (118) configured to direct the vapor refrigerant (120) from the evaporator to an inlet of the compressor (32), and an interface between the discharge and the inlet is without a bend.
