Description

Technical Field

[0001] The utility model relates to the field of defrosting of oil and gas tanks, in particular to a tank bottom defrosting device for oil and gas tanks. Background Art

[0002] Ice blockage is primarily caused by excess water in the refrigeration system. As the refrigerant circulates, the water gradually accumulates at the expansion valve outlet. Because the temperature is lowest at the expansion valve outlet, the water freezes and gradually grows larger. When ice blockage occurs, it completely blocks the expansion valve, preventing refrigerant circulation and preventing the cold storage from cooling. Initially, the refrigeration system will function normally, with frost forming in the evaporator, heat dissipating through the condenser, and the unit running smoothly. The sound of refrigerant flowing through the evaporator is clear and steady. As ice blockage develops, the airflow becomes increasingly weaker and intermittent. In severe cases, this sound disappears, refrigerant circulation is interrupted, and the condenser gradually cools.

[0003] Due to the blockage, exhaust pressure increases, the machine's operating noise increases, and no refrigerant flows into the evaporator. The frosted area gradually decreases, and the temperature gradually rises. Simultaneously, the expansion valve temperature rises, causing the ice to melt and the refrigerant to recirculate. After a period of time, ice blockage recurs, forming a periodic ice blockage phenomenon. Existing defrosting methods mostly achieve the effect of melting the frost in the condenser at room temperature or elevated temperatures. However, this method requires a significant amount of time to defrost, significantly affecting the subsequent use of the condenser. It is also inefficient and extremely inconvenient.
