Getting to know the double-circulation or dual-purpose cold storage in Iran
Business owners mainly need cold storage to carry out their activities. Cold storage can be seen in most businesses and its biggest use is in food and protein stores and hotels, restaurants, fast food, and catering. And it is a great help to store different products for a long time.
The cold room is produced with a sandwich panel body and with proper insulation and the use of functional motors, and it produces a space where the temperature and humidity are completely controlled. It completely freezes all the ingredients inside and prevents them from spoiling and increases the lifespan of the products.
What is a two-circuit refrigerator? A two-circuit refrigerator is one of the types of refrigerators that can operate in both above-zero and below-zero modes, although not simultaneously. In fact, this refrigerator can be adjusted in both modes. And their insulation method is such that it provides the possibility of both.
In double circuit cold stores, there is a significant point that in order to redefine the temperature of the cold store, it must be completely emptied and all its walls must be disinfected again because there may be leftovers from previous products and it will not cause decay and pollution and cause emit an unpleasant smell.
To store food, you must use refrigerators with different temperatures, but the production of several separate refrigerators is really expensive, so the use of dual-purpose or dual-circuit refrigerators alleviates this need and is optimal. Dual-circuit refrigerators have the ability to store and It has a low level of food storage.
In these cold stores, compressors are used with different types of refrigerants (ammonia or pharaoh) and water-cooled or air-cooled condensers are used, and this cold store is assembled according to the type of climate.
The engine of these refrigerators is used in a way that has the ability to produce cold up to minus 40 degrees Celsius.
These refrigerators need proper insulation and sufficient sealing to keep the cold well. The use of polyurethane sandwich panels is the best option for producing these refrigerators, and it is easily portable and portable, like connection refrigerators. and fixed cold storages.
What is the use of double-circuit cold storage? This model of cold storage is used to store fruits and vegetables, protein products, spices, pickles, dried fruits, chicken and meat, chemical and medicinal materials, legumes. These cold storage models are divided into two modes above zero and below zero.
What are subzero cold storages? Subzero refrigerators are designed in such a way that they provide the ability to create subzero temperatures and are suitable for storing perishable food such as red meat, poultry, and protein products, ice cream, and pizza cheese. Their temperature range is between 32 The degree is below zero and the capacity is 1.5 to 70 horsepower. Due to the production of low temperatures in sub-zero cold stores, during the construction of this cold store, the seams of the walls and ceilings must be completely airtight and prevent air from entering and leaving.
What are cold storages above zero? Due to its efficiency, this cold room is built with a temperature range between 1 and 5 degrees Celsius, and it is usually used to store citrus fruits, vegetables, and fruits. Temperatures above zero have the ability to produce microbial, chemical, and physical spoilage. In order to place these products in these containers, measures such as product packaging, grading, and cooling are necessary. Cold storage above zero can be used for short-term storage of dairy products, as well as meat, chicken, and fish.
The storage time of the products in these cold stores is between 1 to 2 days and up to 15 days, because a short period of time is allocated to store the products, it does not need a large capacity because the new product is quickly replaced.
What is the difference between double circuit and single circuit refrigerators? Dual-circuit or dual-purpose refrigerators have motors that are capable of producing cold up to minus 40 degrees Celsius. The insulation method of this cold store is thick and accurate in such a way that it prevents the cold from escaping and they usually use stone wool and injected insulation or polyurethane foam for insulation, if in single circuit cold stores it is too cold. which produces will need to keep more cold, as a result thicker insulation is needed.
Construction of double-circuit cold stores: Zarei Refrigeration Industries is with you dear ones with 20 years of experience in designing and consulting and equipping and installing all types of cold stores, above zero, below zero, and single circuit. In the development of the industry, the most important production step is a warehouse or a place as a cold storage, which makes it possible for the owners, producers and distributors of food to continue their activities. Don’t have enough time to distribute the products, imported goods can’t be distributed in the country on time.
Keeping some special foods on important dates and offering them in months like Ramadan or Nowruz. Some factories and factory productions require a series of raw materials that can be stored in this way. In dual-circuit or dual-purpose systems, the dual cooling system with two independent refrigeration systems provides very low temperature if due to a In the unlikely event that one of the cooling circuits fails, the other circuit can greatly reduce the temperature and provide support until the first circuit is repaired.
Double circuit cold storage cooling system: Hermetic and semi-hermetic compressors are used for the production of double circuit cold stores, which are often procured from reputable European brands. In these cold stores, air-cooled condensers are used according to the capacity of the compartment. Definitely the type of water. And air has a great effect on the type of compressor and condenser. The presence of high and low pressure control systems, expansion valves, accumulators, oil separators, and defrost systems are necessary for the operation of the compressor.
