The present invention relates to a flow balancer for an evaporator, comprising: a permeable assembly comprising at least one gas- and fluid-permeable plate and located above a heat exchange tube bundle of the evaporator; a sealing assembly disposed on a periphery of the permeable assembly and constructed to be nonpermeable to gas and fluid; and a mounting assembly constructed to support the permeable assembly and the sealing assembly. The present invention also relates to an evaporator comprising the flow balancer. The flow balancer of the present invention has the advantages of simple structure and convenient manufacturing and mounting, can balance the pressure distribution above the heat exchange tube bundle, and can achieve a more even distribution of the refrigerant liquid level in the length direction of the heat exchange tube bundle.

Flow balancer and evaporator having the same

A falling film evaporator () includes an evaporator vessel (), a plurality of evaporator tubes () disposed in the in evaporator vessel () through which a volume of thermal energy transfer medium is flowed and a suction port () extending through the evaporator vessel () to remove vapor refrigerant from the evaporator vessel (). A refrigerant distribution system () is located in the evaporator vessel () to distribute a flow of liquid refrigerant over the plurality of evaporator tubes (). The refrigerant distribution system () is configured such that the refrigerant distribution system () has a first height at the suction port () and a second height greater than the first height at a longitudinal location () other than at the suction port ().

Refrigerant distributor for falling film evaporator

A shell and tube heat exchanger having a shell having an inner surface that defines a heat exchange zone, a refrigerant pool zone is arranged in the heat exchange zone, and a plurality of tube bundles are arranged in the heat exchange zone above the refrigerant pool zone. The tube bundles have first and second wall members that define a tube channel, and a plurality of tubes arranged in the tube channel. Each of the first and second wall members have a first end that extends to a second end that is spaced from the refrigerant pool zone. The plurality of tube bundles is spaced one from another so as to define one or more vapor passages. A refrigerant distributor is positioned above the tube channel. The refrigerant distributor delivers a refrigerant onto the plurality or tubes toward the refrigerant pool zone.
