The invention discloses a device for controlling forced oil return of a comprehensive refrigeration house. The device comprises a unit, a barrel pump device, a controller and a cold fan, wherein an ambient temperature sensor is movably mounted above the right upper part of the unit, the controller is electrically connected to the lower left side of the interior of the unit for installation, an oillevel photoelectric sensor is movably installed on the left side of the interior of the unit, the barrel pump device is movably connected to the front of the unit through a pipeline, a system pressure transmitter is installed between the barrel pump device and the unit, the outer side of the unit is electrically connected with a control monitoring wire, the other end of the control monitoring wire is electrically connected with the cold fan, the outer side of the cold fan is electrically connected with an electric valve, and the upper part of the cold fan is electrically connected with a house temperature sensor. According to the device for controlling the forced oil return, adjustment and correction can be automatically carried out according to collected data, and the situation that dueto unnecessary unit oil return faults, the refrigerating unit stops running, and unnecessary economic losses are brought to customers is avoided.
Description
technical field [0001] The invention relates to the technical field of cold storage, in particular to a control device for forced oil return in a comprehensive cold storage. Background technique [0002] For a large-scale cold storage system, according to the utilization rate of the cold storage, when the utilization rate is low, the number of cold storage rooms in the whole system is large, and when the number of cold storage rooms is less than 3, the oil return of the system will not be good. , because the circulation of the system is less, the oil is stored in the air cooler of the terminal equipment, especially in winter, the viscosity of the oil is relatively high, and a small amount of oil returned by the air cooler is enough to meet the oil supply of the compressor unit, resulting in the compressor Insufficient oil supply is a common phenomenon in the market. Contents of the invention [0003] In order to solve the problem of poor oil return of refrigerating units ...
