What is the best refrigerant to use for cold storage to reach minus 145

minus 50 of the cold storage electricity andChillers

Cold storage is a kind of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment different from the outdoor temperature or humidity, and is also a constant temperature and humidity storage equipment for food, liquid, chemical, pharmaceutical, vaccine, scientific experiments and other items. Cold storage is usually located near the port of transport or the place of origin.

Compared with refrigerators, cold storage has a larger refrigeration area and has the same refrigeration principle.

Cold storage has been an important part of the logistics industry since the end of the 19th century.

Cold storage is mainly used for food, dairy products, meat, aquatic products, poultry, fruits and vegetables, beverages, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments, tobacco, alcoholic beverages and other semi-finished products and finished products of constant temperature and humidity storage. Cold storage is a kind of refrigeration equipment, and its refrigeration area is much larger than that of refrigerators, but they have the same refrigeration principle.

Generally, the cold storage is mostly cooled by the refrigeration machine, which uses the liquid (ammonia or freon) with a very low gasification temperature as the coolant, so that it can evaporate under the conditions of low pressure and mechanical control, absorb the heat in the storage, so as to achieve the purpose of cooling and cooling.

The most commonly used is the compressor refrigerator, and the main opening is changed by the compressor and condenser.

Throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into two types: direct cooling and indirect cooling of the blue section. Direct coolingThe evaporation tube is installed in the refrigerated warehouse, and when the liquid coolant passes through the evaporation tube, it directly absorbs the heat in the warehouse and cools down.

Indirect cooling is carried out by a blower.

The air in the warehouse is sucked into the air cooling device, and the air is absorbed by the evaporation pipe hovering in the cooling device, and then sent to the warehouse to cool down. The advantages of the air cooling method are that the cooling is rapid, the temperature in the warehouse is more uniform, and the carbon dioxide generated during the storage process can be removed.

and other harmful gases are taken out of the warehouse.

What refrigerant is used in a cold storage at minus 50.

minus 50 cold storage with what fierce refrigerant Hello dear, there seems to be a kind of r406 can be done quite cold, I see the hospital frozen blood is minus 50 degrees, the compressor is imported from Germany Hello pro, first, high temperature refrigerant is also known as low pressure refrigerant. Its evaporation temperature is higher than 0 and the condensing pressure is lower than that, such as R21, etc., which is suitable for the air conditioning system of centrifugal compressors. 2. Medium-temperature refrigerant is also known as medium-pressure refrigerant.

Its evaporation temperature is -50 0 and the condensation pressure is 1. Envy 5, such as R22, R502, etc. It has a wide range of applications, and is suitable for piston compressor refrigerators, canteen small cold storage, air conditioning refrigeration systems, large cold storage and other branch potato cold devices.

3. Low-temperature refrigerant is also known as high-pressure refrigerant. Its evaporation temperature is below -50 and the condensation pressure is. 0MPa, such as R13, R14, etc., is mainly used in low-temperature refrigeration equipment, such as cascade low-temperature refrigeration devices.

What refrigerant is used in a cold storage at minus 50.

Good evening, dear, I'm honored to answer for you. For your question, I provide you with the following: Generally speaking, the cold storage of 50 can use tetrafreon, ammonia, propane, butane, freon and other fluorine refrigerants, the refrigeration temperature of tetrafreon (R-125) can be reduced to -50, the natural gas refrigeration simple plexus agent R-290 (propane) can also be reduced to -50, and ammonia (R-717) can be reduced to -33, and butane (R-600A) can be reduced to -47, Freon (R-22) can drop to -50.

There are many kinds of refrigerants, R23 refrigerant is one of them, which belongs to ultra-low temperature refrigerant trifluoromethane, freon 23, F23, F-23, HFC-23, refrigerant R23 is mainly used in freeze dryers, low-temperature freezers, environmental test chambers and equipment (thermal shock testing machines), and is mostly used in low-temperature grades for cascade refrigeration systems. At the same time, trifluoromethane R23 can also be used as a gas fire extinguishing agent, which has many advantages such as clean, low toxicity and good fire extinguishing effect. The difference between R22 refrigerant and R23 base refrigerant 1. The use temperature is different

R22 is a high-temperature refrigerant and R23 is an ultra-low-temperature refrigerant. 2. The composition is different: R22 is difluorochloromethane, and R23 is trifluoromethane.

3. The harm to the environment is different: R22 difluorochloromethane belongs to the destructive effect (ODP) and greenhouse effect (GWP) on the high-altitude ozone layer. Developed countries must do so by 2030, and developing countries no later than 2040.

The refrigerants in cold storage generally include ammonia, R22 (freon-22), R12, R11, R502 (mixed refrigerant), organic refrigerant HFC-134A, etc., Zhiyun Refrigeration is very happy to be able to help you.

The refrigerants commonly used in cold storage are as follows:

1. R22 is suitable for most cold storages;

2. Ammonia is suitable for large-scale cold storage, toxic, flammable and explosive.

3. R404A low-temperature refrigerant is suitable for small low-temperature cold storage.

The main refrigerants in cold storage are:

Ammonia (NH3), carbon dioxide (CO2), sulfur dioxide (SO2), chloromethane (CH2Cl), Freon (CCL2 F2).

Among the above cold storage refrigerants, ammonia and freon are the most commonly used with good refrigeration effect.

These two are more common!
