Abstract

The invention provides a device and a method for preventing refrigerants from gathering. The device comprises a temperature detection module, a logic judgment module, a communication module and a flow regulating module which are connected with a single chip microcomputer. The temperature detection module is used for monitoring evaporating temperature of each running indoor unit regularly and storing the evaporating temperatures in a refrigerating system, and when maximum difference of the evaporating temperatures of multiple indoor units is over a set value, the flow regulating module of the indoor units is regulated to enable the maximum difference of the evaporating temperatures of the indoor units to be controlled within the set value.

Description

technical field [0001] The invention relates to a device and method for preventing refrigerant accumulation, in particular to a device and method for preventing refrigerant accumulation in a refrigeration device suitable for multiple indoor units. Background technique [0002] At present, in the multi-line refrigeration system on the market, in order to prevent the refrigerant from drifting during refrigeration, the quantity detected by the temperature sensor is directly processed as an input variable, and after being processed by the MCU, it is used as an output control quantity for Control the opening of the electronic expansion valve to prevent the refrigerant from drifting, thereby improving the performance of the refrigeration system. However, once other situations occur, such as working conditions caused by too long system pipelines, or failures of temperature sensors or electronic expansion valves, etc., this adjustment method cannot be used normally, resulting in the...
