Vacuum dormant quality guaranteeing refrigeration system

Abstract

Provided is a vacuum dormant quality guaranteeing refrigeration system. A refrigeration compressor is arranged outside an airtight pressure-resistant shell connected with a vacuum pump, and an outletof an evaporator unit shell is connected with the airtight pressure-resistant shell through a side flow fan connected with a frequency converter. A gas inlet of the evaporator unit shell is connectedwith a connector of a four-way pipe through a connecting pipe. Another connector of the four-way pipe is connected with the airtight pressure-resistant shell, and one of the other two connectors of the four-way pipe communicates with the outer atmosphere through an electric ball valve, and the other of the other two connectors of the four-way pipe is connected with a nitrogen storage tank throughan electric ball valve. A pressure sensor, a temperature sensor and a gas detecting sensor are further arranged in the airtight pressure-resistant shell, and the pressure sensor, the temperature sensor, the gas detecting sensor and the electric ball valves arranged on all pipelines are connected with a power inverter, a power source, a circuit board and an intelligent control panel through guide lines. According to the vacuum dormant quality guaranteeing refrigeration system, objects stored in the pressure-resistant shell can be isolated from air to be refrigerated or frozen, the stored mattercan be in an anaerobic and dormant state, and quality guaranteeing and freshness retaining are achieved.

Description

technical field [0001] The invention relates to a refrigeration system. Background technique [0002] The traditional way to preserve the quality and freshness of substances is to place them in a purely refrigerated or frozen environment, such as refrigerators, freezers, refrigerated trucks and cold storage. Although these substances are in a low-temperature environment, they are still in the air. Under the action of oxygen and bacteria in the air, , can only temporarily delay the deterioration or nutrient loss of stored substances, and cannot meet the quality and freshness preservation needs of various substances. Someone invents a vacuum refrigeration storage device for this reason, which mainly includes: an airtight pressure-resistant housing and its supporting vacuum pumping mechanism and refrigeration mechanism. The device can isolate the substances stored in the airtight pressure-resistant shell from the air, not only kills bacteria but also does not have an oxidation...

AI Technical Summary

Problems solved by technology

This refrigeration method is more suitable for containers that are rarely switched on and off, such as refrigerated or frozen containers, but it is not suitable for refrigerated or frozen devices that are frequently switched on and off, because the switch needs to be inflated first, and the material must be vacuumed after entering and exiting, which is troublesome to operate; at the same time The airtight and pressure-resistant shell is in a vacuum state for a long time, and its seal is easy to leak, which shortens the service life
