Description

Technical Field

[0001] The invention relates to the technical field of liquid-filled evaporators, in particular to a liquid-filled evaporator. Background Art

[0002] Features of the full-liquid shell and tube evaporator. Widely used in ammonia refrigeration systems, and can also be used in Freon systems, with a compact structure and a small footprint. The refrigerant can be used in a closed cycle, and a volatile refrigerant can be used, which is easy to accumulate oil. The refrigerant is prone to freezing; the refrigerant goes through the shell side, and the water goes through the tube side. The heat exchange process is always the heat exchange between liquid refrigerant and liquid water. The generated refrigerant gas directly enters the compressor from the compressor suction, and the heat exchange area is effectively utilized, which improves the heat exchange efficiency of the unit. The refrigerant used in the full-liquid evaporator in the prior art is converted between liquid and gas. When the internal liquid level is in a boiling state, the compressor lubricating oil mixed in the liquid floats on the liquid surface due to density problems and is flushed by the boiling refrigerant to form oil bubbles. When there are too many oil bubbles, it will affect the monitoring of the liquid level sensor and the replenishment of the refrigerant. At the same time, it will cause the oil and liquid refrigerant to flow back to the compressor to cause component damage.
