摘要:
A falling film evaporator for use in a vapor compression refrigeration chiller preferably employs a two-phase refrigerant distributor that overlies the tube bundle in the evaporator shell. The tube bundle defines at least one vapor lane which facilitates the conduct of refrigerant vapor from the interior of the tube bundle to the exterior thereof in a manner which does not substantially affect the vertically downward flow of liquid refrigerant through the tube bundle and across the vapor lane.
摘要:
Two variable position supply air valves, one for modulating warm airflow to a comfort zone and the other for modulating cool airflow, each have a constant intermediate open position to provide at least a desired minimum airflow, and both can be controlled so that only one valve is open at any one time to minimize any mixing of the airstreams. Potentiometers are used to adjust the intermediate open position of each valve and to adjust at least one valve's relationship of valve opening to zone temperature.
