Abstract

The invention provides a low-temperature storage device and a control method thereof, and relates to the technical field of low-temperature storage. The low-temperature storage device is used for solving the problem that a load of a compressor is large when a refrigeration system of an existing low-temperature storage device starts to run, and a protector is easy to trip. The low-temperature storage device comprises a fourth connecting branch, a control valve, an expansion container, and a detecting device, wherein one end of the fourth connecting branch is connected with an air outlet of a liquid distributor, and the other end of the fourth connecting branch is connected with an air suction port of the compressor; the control valve is arranged on the fourth connecting branch, and the expansion container is connected with the fourth connecting branch on the downstream side of the control valve; and the detecting device is configured to detect a pressure value in the fourth connecting branch located on the upstream side of the control valve, and when the pressure value is greater than or equal to a threshold value, the control valve is opened so that a refrigerant flowing out of theair outlet of the liquid distributor flows into the expansion container along the fourth connecting branch. The device may be used for low temperature storage of articles.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage, in particular to a low-temperature storage device and a control method thereof. Background technique [0002] With the development of the times, there is more and more demand for low-temperature storage devices in the market. For storage devices with a storage temperature of -40°C and above, a single-stage refrigeration cycle is generally used to achieve, but if the required temperature is lower, single-stage The refrigeration cycle cannot meet the requirements. For storage devices with a temperature requirement of -40°C to -60°C or below -60°C, automatic cascade refrigeration technology is generally used for refrigeration. [0003] However, in the existing cascade refrigeration system, when the compressor is just turned on and warmed up, since the refrigeration system has not yet established a stable operating state, the discharge and suction pressure of the compressor are high a...
