Cold Storage or Cold Storage are controlled spaces designed to preserve food, medicines and products at low temperatures to prevent their corruption. Refrigerators are used in the food, pharmaceutical, agricultural and even industrial industries. To fully understand the structure, the types and types of refrigerations, different dimensions such as temperature range, type of application, type of refrigeration, dimensions, design and implementation must be taken into account. The following is a comprehensive one to each of these.
construction of a variety of refrigerators in Qom
In the category of refrigerators, different parameters are used in the refrigerant industry, including the temperature range of the cold storage, their use, the type of refrigerant used in the design of the refrigerator, which we will technically examine.
Refrigerator above Zero (Maintenance Refrigerator)
These types of refrigerators are designed to store products that do not need to be frozen. The temperature of these refrigerators is usually between 0 and 15 ° C. These types of refrigerators are used to store fruits, vegetables, dairy and other foods.
Under Zero Refrigerator (Freezing Refrigerator)
The temperature of these types of refrigerators is usually from negative 18 degrees Celsius to negative 40 degrees Celsius and is often used to store frozen products such as meat, fish and other food products that should be kept in freezing. In this method, the sub -zero chiller or condensing unit is commonly used to create cooling or cooling.
Industrial Refrigerator: Usually used to maintain high volumes of crops in the food, pharmaceutical, or agricultural industries.
Store Refrigerator: Product maintenance is used in stores and supermarkets and usually has smaller dimensions.
Pharmaceutical refrigerators: This system is designed to maintain medicines and medical products and requires more precise control over temperature and temperature and temperature. They have moisture.
Movable refrigerators: These types of refrigerators are installed on trucks or containers and used for food or medicine transportation.

Design and Construction Tips
Many parameters should be considered in the design and manufacture of cold warehouses. For example, some of these factors are: the dimensions of the refrigerator, how to execute and build, calculate the price, etc., all of which must reach the equilibrium and equilibrium engineering principles
Dimensions. And the design of the cold stores
Dimensions of the cold stores vary depending on the type of use, product volume and specific customer needs. The following factors are considered in the design of these systems:
Internal volume (capacity): should be proportional to the amount of product and its maintenance type.
Insulation : Walls, ceiling and fridge floor should be well insulated to prevent heat penetration into and loss of energy. Polyurethane panels are usually used with different thicknesses.
Ventilation and Humanity System: To control moisture and prevent ice formation on products, these systems are essential in refrigerations.
System Refrigeration: should be selected based on temperature needs and refrigerant type. Types of refrigeration systems include direct evaporative systems and indirect systems (chillers).
Implement and build a refrigerator
Implementation of a refrigerator requires collaboration between different teams, because various technical and environmental parameters are involved.
Engineering and Design: Need to carefully design mechanical and electrical maps and calculations. BR> Construction: Installation of insulation panels, doors, and floods.
Installation of refrigeration system: Installation of compressors, condensors, evaporators and accessories.
Control and Supervision: Installation of monitoring systems for temperature control and necessary warnings. br>
Calculate the Price of Refrigerator
Dimensions and capacity of the refrigerator: The larger the refrigerator, the more the cost of materials and equipment. Refrigeration equipment plays a big role in price.
Insulation Quality: Using high quality insulation and thickness increases the cost of construction.
Installation: If the refrigerator Remote areas, shipping and installation costs will be higher.
Intelligent Control Systems: Surveillance and intelligent systems for temperature control, humidity and warnings may add to the final cost. >
What is the difference with the freezing tunnel?
The difference between the refrigerator and the freezing tunnel is generally in the speed of freezing, use and temperature conditions. Each of these two types of refrigeration systems are designed for various purposes, which we will discuss below:
is a large, low -temperature refrigerator used for long -term maintenance of products and usually at constant temperature (at constant temperature ( They operate above zero or below zero) and are mostly used to store food, medicines and crops that need to keep cool or freezing.
The freezing tunnel is a system designed for rapid freezing products. . In the freezing tunnel, the products reach temperatures below zero (usually below 40 degrees Celsius) in a short period of time, causing water to be frozen rapidly and forming smaller ice crystals. This process contributes to the higher quality of the frozen product.
