Problems solved by technology

[0002] At present, the country advocates that grain storage requires low-temperature storage to ensure freshness and long-term storage of grain. Traditional coolers have a small air supply temperature difference and cannot provide effective low-temperature air supply under high external temperature conditions, so that low-temperature grain storage cannot be effectively realized. purpose; in addition, the existing cooling unit has a large volume and high energy consumption

Abstract

The embodiment of the invention discloses a cooling machine, which is provided with a pre-cooling evaporator and a secondary evaporator connected by a centrifugal fan. The cooling machine provided in the embodiment of this application adopts a double refrigeration cycle; the heat exchanger adopts two-stage evaporation, and the pre-cooling evaporator is responsible for heat exchange with the high-temperature air outside. Direct cooling, to get a certain temperature drop, and sent to the secondary evaporator by the centrifugal fan to continue the heat exchange, thus ensuring a large temperature difference, low temperature air supply, and effectively realizing the cooling effect.

Description

technical field [0001] The invention relates to a cooling machine, more specifically, to a cooling machine with large temperature difference and low wind. Background technique [0002] At present, the country advocates that grain storage requires low-temperature storage to ensure freshness and long-term storage of grain. Traditional coolers have a small air supply temperature difference and cannot provide effective low-temperature air supply under high external temperature conditions, so that low-temperature grain storage cannot be effectively realized. The purpose; In addition, the existing cooling machine unit has a large volume and high energy consumption. Contents of the invention [0003] In view of this, the present application provides a cooler with large temperature difference and low airflow, which adopts a two-stage evaporative refrigeration method, effectively realizes air supply with large temperature difference, and has a better cooling effect. [0004] To ac...
