Series Intelligent Hot-Gas Defrost System

It is widely used in scenarios such as fruit, vegetable and aquatic product preservation, medical vaccine storage, and fungus cultivation and breeding. 1. This complete set of units adopts advanced thermal fluorine defrosting technology to achieve on-demand defrosting, no frost, and short defrosting time. During defrosting, the unit operates in heat pump mode, absorbing heat from the outside for defrosting, and defrosting consumes less power. After defrosting, Small temperature fluctuation with the cold room, saving energy and reducing carbon emissions. 2. During the thermal fluorine defrosting process, the oil accumulation on the inner wall of the air cooler or aluminum row is effectively removed to improve the heat exchange efficiency of the air cooler. 3. Gentle defrosting: the refrigerant hot gas temperature and mass flow rate gradually increase; the thickened air cooler copper tube is more resistant to cold and hot shocks. 4. Improve heat exchange efficiency: Using EVI economizer, the cooling capacity is increased by more than 20%, the energy efficiency is increased by more than 15%, which is much higher than the cooling capacity and energy efficiency improvement of the flash tank, and the EVI (Enhanced Vapor Injection) intervention timing is reasonable to achieve energy saving and emission reduction. 5. The electronic expansion valve PID coefficient is reasonable and the response speed is fast. It uses a low-temperature special compressor for R507/R404A refrigerant. 6. Simplified operation and maintenance: pre-charged with refrigerant, easy installation, only need to connect the liquid supply and return steam pipelines; remote monitoring, can detect various parameters in real time through a computer or mobile phone, remote start and stop; remote monitoring, can detect various parameters in real time through a computer or mobile phone, remote start and stop; It has the function of pump-down and timed start and stop.
