Problems solved by technology

[0002] At present, the refrigeration above -36°C almost uses ammonia as the refrigerant. The domestic tuna storage at -60°C is 100% imported from Japan, and all of them use Freon cascade refrigeration system, which uses R-22 and R-23. This kind of refrigeration system, the biggest disadvantage is that Freon destroys the ozone layer of the atmosphere, and the production and use of it will be stopped at home and abroad.

Embodiment

[0030] There are three types of tuna storage temperatures in the world: -50°C, -55°C, and -60°C. According to the most advanced international tuna storage temperature of -60°C, R717 is used as the refrigerant for -60°C tuna storage. The insulation layer around the ceiling and the ground of the -60°C tuna storage warehouse is made of polyurethane with a thickness of 450mm. In order to prevent the polyurethane from cracking at -60°C, the thickness of the polyurethane is sprayed at 50mm each time. After cooling and shrinking, spray another The first floor; the cold storage adopts a double-chamber structure, the outside is a preparation room at -30°C, the inside is a storage room at -60°C, and the temperature difference is -30°C.

Abstract

The gas-liquid separation heat exchange and return gas regulating station is characterized in that the lower high-efficiency heat exchange tube (32) and the upper high-efficiency heat exchange tube (40) are arranged inside, and the heat exchange tube room (39) is arranged between the tubes, and the outer part is respectively Through the return air pipe (31) of the -60°C evaporator, the suction pipe (36) of the single-unit freezer, the liquid inlet pipe (37) of the ammonia liquid reservoir, the R717 liquid adjustment station pipe (38) and the low temperature evaporator (1), The stand-alone refrigerator (4), the ammonia liquid reservoir (11), and the ammonia liquid regulating station (8) are connected, and are fixed by a fixed partition (33), a head (34), a fixing bolt (35), and a partition (41) .

Description

1. Technical field [0001] The invention relates to a gas-liquid separation heat exchange return air regulating station, in particular to a gas-liquid separation heat exchange return air regulating station for ultra-low temperature cold storage, belonging to the technical field of gas-liquid separation regulating station structure. 2. Background technology [0002] At present, the refrigeration above -36°C almost uses ammonia as the refrigerant. The domestic tuna storage at -60°C is 100% imported from Japan, and all of them use Freon cascade refrigeration system, which uses R-22 and R-23. The biggest disadvantage of this kind of refrigeration system is that Freon destroys the ozone layer of the atmosphere, and its production and use will soon be stopped at home and abroad. There is no precedent for the ultra-low temperature of the ammonia system, and the use of ammonia as a refrigerant has no damage to the ozone layer of the atmosphere. 3. Contents of the invention [0003...
