The effect of changes in exhaust pressure (condensing pressure) on the system When the refrigeration system is running, the exhaust pressure corresponds to the condensation temperature, and the condensation temperature is related to the flow and temperature of its cooling medium, the amount of refrigerant injected, the efficiency of the compressor, and the amount of cooling load. When checking the refrigeration system, you can install an exhaust pressure gauge on the exhaust pipe when inspecting the refrigeration system to detect the exhaust pressure as a fault analysis data. Factors of high exhaust pressure. The exhaust pressure is higher than the normal value due to the following factors: low cooling medium flow rate or high cooling medium temperature, excessive refrigerant charge, heavy cooling load, etc. The above factors will increase the circulation of the system, and the condensing heat load will increase accordingly. In order to adjust the heat dissipation, the only way to incr...

  What’s the difference between plate freezer and blast freezer? As for blast freezing, we have different machines to make it. For example, spiral freezer, tunnel freezer, liquid nitrogen freezer. But most popular, it’s the plate freezer and blast freezer. So here are the differences.  1. Blast freezer For a blast freezer or air blast freezer, only the evaporator is working. It guarantees the room temperature to be between -30C and -40C. Products inside the cold room would be get frozen within certain hours, like 4 hours, 8 hours, or 20 hours. Blast freezer is used to keep food safe at very low temperatures for the long time. Normally we would use the trolley to carry the products. So it’s very flexible and most products are no problem.  2. Plate freezer But as for the contact plate freezer. You see, it doesn’t have any fan motors. Only the freezing aluminum plate. Plate freezers are designed to meet limited space requirements. Stainless steel panels on both sides. Good i...

For CRYO’s refrigeration unit, we use the controller EK-3030E (Elitech brand). Most of our customers do not know how to set the room temperature and other parameters for this type of controller. Now, let us learn together: Full article:   cold room control 1) Set the room temperature: Firstly, if you see there is a lock signal displayed on the screen, we should unlock the keyboard by pressing the ’OK’ button for one second. Secondly, press ‘off temp’ button and the screen will show off temp. Then, you can use ‘up arrow’ button or ‘down arrow’ button to change this off temperature value. 2) Set other parameters: Under the status of controller unlocking, press ‘OK’ button for 5 seconds, and it will display code ’F1’ on the screen. Then, press the ‘up arrow’ button to select the parameters that you want to set. Finally, press ‘OK’ button to enter this parameter and change its value. Cold Room Remote Control Platform (an APP developed by Cryo System) is the advanced way to  c...

1. The common refrigeration basics Major terms:  temperature, heat, specific heat, sensible heat, latent heat, pressure, evaporation, boiling, thermal conductivity, convective heat transfer coefficient, heat transfer coefficient, heat emission coefficient, density, humidity, enthalpy, entropy, and diagram of pressure enthalpy. For more check with our blog:  The Common knowledge of refrigeration basics and refrigeration cycle 2. The Refrigeration Cycle Refrigeration system fundamental components: The compressor The condenser The metering device The evaporator The receiver The refrigerant enters the  compressor  as a warm, saturated low-pressure gas, leaves the compressor as a superheated (hot) high-pressure gas, And then enters the  condenser  as a superheated (hot) high-pressure gas, leaves the condenser as a regular temperature, saturated high-pressure liquid, The refrigerant enters the   evaporator   as a cold, low-pressure liquid, leaves the ev...

oil return efficiency   Compressor oil is very important for the crankshaft in refrigeration equipment. Under the serious disability of oil, the compressor could wear down within a few hours. 1.  Compressor oil is very important for the crankshaft.  Under the serious disability of oil, the compressor could wear down within a few hours. 2. So during the installation of a split system, we should  pay attention to the copper pipe. If the compressor is higher than the evaporator, the copper loop is a must. The suction line should be as short as possible, as little welding as possible, etc. 3. After all copper welding is done and during the machine commissioning, we should  calculate oil return speed. How many time does it start to return after the compressor start? We must guarantee oil return is on time, so the whole system could run in good condition during its service life.   For more, please feel free to contact us!

Firstly, how seafood goes badly? At a certain temperature, the bacteria grow fast, and they will decompose the proteins, fats, and amino acids of the seafood, turns out, the seafood goes badly? And using a cold room to keep them, can maintenance at a temperature that stops the bacteria from growing. Just is like a seafood cold room, and there are several solutions 1. Blast freezing – we use the blast freezer room for fish 2. Keep fish at 0~-4C degrees. 3. Ice layer + fish layer. for more detail check: the seafood cold room to keep frozen For different kinds of seafood, the storage solution is different, for example, the deep-sea fish need to be stored at very low temperatures like -60C degrees. What kind of your seafood? Contact us for a cold room solution. For the seafood cold room design , you could check the article.

How much is the construction and installation of 500㎡ cold storage for garlic ? The cost of cold storage mainly depends on the three requirements of cold storage size, temperature requirements, and refrigeration unit requirements. The construction and installation costs of garlic cold storage mainly include the following points: 1.  Insulation cost of garlic cold storage:   The insulation board material is generally selected from polyurethane foam and double-sided color steel; the thickness used is generally determined by the temperature of the storage 2.  Garlic cold room equipment costs:   Garlic cold storage has many brands of refrigeration compressors, air coolers, refrigerants, expansion valves, etc., and suitable brands are recommended according to customer requirements and the budget of the cold storage; 3. Garlic cold storage circuit costs:   signal points, electric control boxes, sound and light alarm equipment, sensors, etc.; 4. Garlic cold storage pip...
