AI Technical Summary
Technical Problem
In existing refrigeration systems, the compressor is easily damaged during the defrosting process after the evaporator frosts, and defrosting also affects refrigeration efficiency.
Method used
The system adopts a parallel evaporator branch design. In defrosting mode, the refrigerant is directed to the non-target evaporator by switching components, and the target evaporator is used for defrosting. At the same time, when switching to cooling mode, the refrigerant is diverted to the return valve and bypass valve to reduce the pressure flowing to the compressor.
Benefits of technology
This reduces the risk of compressor damage during the transition from defrosting mode to cooling mode, while maintaining the cooling capacity and defrosting efficiency of the refrigeration system.

Abstract
The utility model provides a kind of refrigeration system and refrigeration house, refrigeration system includes refrigeration cycle loop and switching component, refrigeration cycle loop includes compressor, condenser and evaporative component in series successively, evaporative component includes at least two parallel evaporative branch, each evaporative branch includes throttling element, evaporator and back gas unit in series successively, back gas unit includes back gas valve and bypass valve in parallel with each other;Switching component is connected with refrigeration cycle loop, switching component has closed state and open state;In the process that refrigeration system switches from defrosting mode to refrigeration mode, the back gas valve and bypass valve of original target evaporative branch are opened first, then, the bypass valve of original target evaporative branch is closed.In the process that a part of evaporator defrosting ends and switching refrigerant flow path, the risk of compressor of this refrigeration system is lower.
