The main part of the cold storage refrigeration system
The cold storage refrigeration system includes 4 main parts: compressor, condenser, expansion valve (throttle valve), and evaporator. The entire refrigeration system of the cold storage is connected by a circulating pipeline to form a closed circuit. Refrigerant is charged in the pipeline. The compressor plays the role of compressing and transporting the refrigerant gas in the refrigeration system of the cold storage, that is, the low-pressure and low-temperature gas generated in the evaporator is sucked back, compressed again into high-temperature and high-pressure gas and sent to the condenser. www.yanghuzl.com (Changzhou Yanghu Refrigeration specializes in the production of polyurethane cold storage panels). The expansion valve is installed between the liquid receiver and the evaporator, and is a part of the high-pressure area and the low-pressure area in the system.

Method for low temperature refrigeration of meat and meat products
We eat a lot of meat every day, and the supply of meat is different every day, so some fresh meat or meat products need us to be refrigerated at low temperature. www.yanghuzl.com (professional production of cold storage board) low temperature storage method is carried out in cold storage or refrigerator, which is the most practical method in the storage of meat and meat products. Under low temperature conditions, especially when the temperature drops below minus 10°C, the moisture in the meat freezes, creating an environment where bacteria cannot grow and develop. But when the meat is thawed and reconstituted, bacteria start to multiply again due to the increased temperature and oozing juices. Therefore, when using low-temperature storage of meat, it is necessary to

Outer protective material of polyurethane cold storage board
The polyurethane cold storage board is composed of an outer protective plate and a polyurethane foam material, so what materials can be used as the outer protective material of the polyurethane cold storage board? Yanghu Refrigeration will answer for you: Generally speaking, there are five kinds of aluminum plate, stainless steel plate, color zinc steel plate, salted steel plate, and standard floor plate. We usually use more color zinc steel plate, and the price is relatively suitable. Embossed aluminum plate It is generally used on the bottom plate, and the stainless steel plate is often used in the experimental library. The general cold storage board is customized by the user, and the length, width and height of the storage body are given according to the actual situation, and then the manufacturer designs the size of each board according to these dimensions. High and medium temperature cold storage, a

The benefits of choosing high-quality polyurethane cold storage panels
The choice of the cold storage board is very important for the cold storage, because the cold storage is different from the ordinary warehouse, the temperature in the cold storage is generally relatively low, and the air temperature, humidity, and environmental requirements are relatively High, so when we choose the cold storage board, we must pay attention to choose the cold storage board that has better temperature control. Deterioration, or make the refrigeration compressor of the cold storage work frequently, waste more resources and increase the cost. Choose the right board for better maintenance

Analysis of the characteristics of polyurethane cold storage board
Everyone knows that polyurethane is the main material for making cold storage panels, but do you know why polyurethane is used as the main material for cold storage panels? What are its characteristics. Below, Yanghu Refrigeration will briefly answer the characteristics of polyurethane cold storage panels: 1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35~40kg/m3, the thermal conductivity is only 0.018~0.024w/(m.k), which is equivalent to about half of EPS, which is the lowest thermal conductivity among all thermal insulation materials at present. 2. Rigid polyurethane has moisture-proof and waterproof properties. The closed cell ratio of rigid polyurethane is 9

Assembly principle and advantages of polyurethane hook plate
The traditional common cold storage is composed of hook plates, so do you know its assembly principle and advantages? Yanghu Refrigeration will introduce to you: ①The connection method of the storage board is eccentric hook connection, which is easy to install and disassemble, and the storage body is very strong. The senior designer uses the principle of architecture to creatively adopt the "one board locks two boards" method. The technical method not only ensures the beauty of the library body, but also ensures the practicability and durability of the library body. ②The eccentric hook core is made of steel, and the quality of the hook box is the best in China, which ensures the firmness and tightness of the connection of the library board. ③The seam of the library board is sealed with a unique rubber strip, and it can also be punched at the same time.

Changzhou Yanghu Refrigeration Equipment Co., Ltd. Main Products
Changzhou Yanghu Refrigeration Equipment Co., Ltd.'s main products are polyurethane handmade panels and machine-made panels, and the main materials are color steel and polyurethane, collectively referred to as polyurethane sandwich panels. The following is a detailed introduction to the product specifications: 1. Handmade board: Generally, we call the conventional handmade board a hook board, which is composed of color steel plate and foaming material, and is mainly used in refrigerators, fresh-keeping warehouses, etc. The construction period is long, but the surface of the polyurethane sandwich panel made is smooth, the density is high, the installation is beautiful, and it can be flame-retardant. Color steel thickness is optional, the thinnest is 0.376mm; plate thickness can be produced: 5cm, 7.5cm, 10cm, 12cm, 15cm

Several requirements to ensure the quality of polyurethane cold storage board
The quality of the polyurethane cold storage board is related to its steel plate thickness, foaming density, and production process. Below, Yanghu Refrigeration will introduce the specific requirements of these factors: 1. The thickness of the steel plate of the cold storage board: In general, the thickness of the color steel plate is more than 0.35mm, which is the most basic. If you have higher requirements, you can also choose thicknesses such as 0.4mm and 0.5mm! Color steel less than 0.35mm will easily appear a lot of air bubbles on the surface of the board during the foaming process of the library board, which will affect the appearance. The minimum steel plate requirement for Yanghu Refrigeration in Changzhou City is 0.376mm, and users can purchase it with confidence. 2. Cold storage board

Interpret the usable area of polyurethane sandwich panels
Polyurethane sandwich panels are combined with beautiful appearance, long service life and wide use area. They integrate load-bearing, heat preservation, fire prevention and waterproofing. They are fast and convenient to install, have short construction period, good comprehensive benefits, and have good cost-effective advantages. The best material for refrigeration is also a potential high-efficiency and energy-saving building envelope material. It is a new type of energy-saving board advocated and promoted by the Ministry of Construction. There are two types of polyurethane sandwich panels: hook type and plug-in type. The hook type is a traditional handmade board with a short production cycle. The plug-in type is a mechanism board with a short production cycle and is suitable for large-scale projects. www.yanghuzl.com

Precautions for the storage of fruits and vegetables in fresh-keeping cold storage
People who grow vegetables at home may have this experience. If the fruits and vegetables to be refrigerated are not treated and stored, they will find that the fruits and vegetables are easily rotten, and good food is wasted in vain. Each type of fruits and vegetables has different storage methods. Reasonable use, will do twice the work. Yanghu Refrigeration will explain to you the precautions when using cold storage for freshness: 1. The temperature adopts cold storage fresh technology, and it is the key to control the temperature in the cold storage.
