Technical Field

[0001] The utility model relates to the field of refrigeration equipment, in particular to an energy-saving low-temperature unit for grain bins. Background Art

[0002] The low-temperature unit for grain bins cools the grain stored in the grain bin by generating low-temperature air through refrigeration to prevent the grain from getting hot and damaged. The condensed water on the evaporator of the existing low-temperature unit for grain bins is directly collected and discharged, and the condenser of the low-temperature unit for grain bins completely relies on the condensation fan to drive the air flow for heat dissipation. Since the condensed water itself is low-temperature water, directly discharging the condensed water is a waste of low-temperature water resources. And the condenser needs a low-temperature medium for cooling. Therefore, how to use the low-temperature water for cooling the condenser has become a research problem for the low-temperature unit for grain bins. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the problems existing in the prior art, such as the direct discharge of condensed water causing waste of low-temperature water resources and the high energy consumption for cooling the condenser, and to provide an energy-saving low-temperature unit for grain bins.

The compressor, the condenser, the liquid storage tank, the expansion valve, and the evaporator are connected by copper pipes to form a refrigerant circulation channel. A condensation fan is installed on the front of the mechanical chamber. A first water receiving tray for collecting the condensed water dripping from the evaporator is installed directly below the evaporator. A drip pipe is installed at the top of the condenser. The bottom of the first water receiving tray is connected to the water inlet of the drip pipe through a drain pipe. A plurality of water dripping holes facing the condenser are opened at the bottom of the drip pipe.

One end of the sewage discharge pipe away from the second water receiving tray extends to the outside of the stainless-steel box body, and a plug is installed at the end of the sewage discharge pipe away from the second water receiving tray.

[0009] Wherein, an overflow pipe is installed at the top of one end of the filter pipe close to the first water receiving tray, and one end of the overflow pipe away from the filter pipe extends to the outside of the stainless steel box body.
