Full-liquid evaporator has a compact structure. Heat transfer effect is good, easy to install, easy to use. Widely used in chiller, in the full liquid evaporator, liquid refrigerant in the tube flow, full liquid evaporator mainly horizontal full liquid evaporator.

Horizontal full-liquid evaporator, this evaporator has a steel plate rolled and welded into a cylindrical shell, the shell is welded at both ends with two round tube plates. Tube office drilled many small holes, each small holes installed in a tube, tube ends with rising joint method or welding method fastened in the tube holes of the tube plate, forming a group of direct tube bundle. If the tube is too long, the chiller can be installed in the body of the simple one or several support plates to prevent the tube from sagging. Simplified body is equipped with two ends of the head, the head can be cast iron casting, can also be made of steel plate, the head is equipped with a partition, the tube according to a certain number of tubes and the flow direction is divided into several processes, so that the refrigerant carrier according to the specified flow rate and direction of the flow in the tube back and forth flow. Refrigerant according to a certain liquid level height charged in the shell, it absorbs the heat of the carrier refrigerant in the tube between the tube after vaporization, so that the carrier refrigerant remembers to cool. In order to prevent the vapor from evaporator lead out of the entrained liquid, in addition to controlling the liquid level height, sometimes in the upper part of the simplified body set the gas bag, to achieve the purpose of gas-liquid separation.

With the turbine compressor supporting the overall structure of the full-liquid ammonia Lyon evaporator and general horizontal full-liquid evaporator is similar, the difference is that in the tube bundle is equipped with a baffle plate, in order to block the liquid droplets from the evaporation of the gas brought out. In addition, the upper part of the vessel is not equipped with tube bundles to reduce the resistance to vapor flow.
