Chiller cold storage construction
Fresh-keeping storage is a storage method that inhibits the activity of microorganisms and enzymes and prolongs the shelf life of fruits and vegetables. The preservation temperature range of fruits and vegetables is 0℃～5℃. Fresh-keeping technology is the main method of low-temperature preservati...Read more -
Refrigeration compressor knowledge
1. Why does the compressor have to run continuously for at least 5 minutes and stop for at least 3 minutes after shutting down before restarting? Stopping for at least 3 minutes after shutting down before restarting is to eliminate the pressure difference between the compressor inlet and exhaust....Read more -
Six protective parts for air-cooled chiller refrigeration compressor
1. Internal thermostat (installed inside the compressor) In order to prevent the air-cooled chiller from running continuously for 24 hours, causing the compressor to run at high load, the electromagnetic switch is bad, the shaft is stuck, etc., or the motor is burned due to the motor temperature....Read more -
How to manage cold room？
When you have considered starting a cold storage, have you ever thought about how to manage it after it is built? In fact, it is very simple. After the cold storage is built, how should it be managed correctly so that it can work normally and safely. 1. After the cold storage is built, preparatio...Read more -
How to reduce the cost of cold storage construction?
We are all very familiar with cold storage, which is very common in life. For example, fruits, vegetables, seafood, medicines, etc. all need to ensure freshness. Therefore, the utilization rate of cold storage is getting higher and higher. In order to increase customer satisfaction and higher ben...Read more -
Why suction pressure of the cold storage is high?
Reasons for excessive suction pressure of compressor cold storage equipment 1. The exhaust valve or safety cover is not sealed, there is leakage, causing the suction pressure to rise. 2. Improper adjustment of the system expansion valve (throttling) or the temperature sensor is not close, the suc...Read more -
HOW TO INSTALL COLD ROOM ?
Material preparation before installation The cold storage equipment materials should be equipped according to the cold storage engineering design and construction material list. The cold storage panels, doors, refrigeration units, refrigeration evaporators, microcomputer temperature control box...Read more -
Why does the cold storage compressor crankshaft break?
Crankshaft fracture Most of the fractures occur at the transition between the journal and the crank arm. The reasons are as follows: the transition radius is too small; the radius is not processed during heat treatment, resulting in stress concentration at the junction; the radius is processed ir...Read more -
Reasons for low suction pressure of cold storage compressor
Reasons for low suction pressure of compressor cold storage equipment 1. The liquid supply pipe, expansion valve or filter of the refrigeration system is blocked by dirt, or the opening is too small, the float valve fails, the system ammonia liquid circulation is small, the intermediate cooler li...Read more -
Why does the cold storage compressor consume a lot of oil?
The reasons for high oil consumption of refrigeration compressors are as follows: 1. Wear of piston rings, oil rings and cylinder liners. Check the gap between piston rings and oil ring locks, and replace them if the gap is too large. 2. The oil ring is installed upside down or the locks are inst...Read more -
What is the problem of frequent tripping in cold storage?
What is the reason for frequent tripping in cold storage? 1. Overload. When overloaded, you can reduce the power load or stagger the power usage time of high-power equipment. 2. Leakage. Leakage is not easy to check. If there is no special equipment, you can only try one by one to see which equip...Read more -
What’s problem with the cold storage not cooling?
Analysis of the reasons why the cold storage is not cooling: 1. The system has insufficient cooling capacity. There are two main reasons for insufficient cooling capacity and insufficient refrigerant circulation. The first is insufficient refrigerant filling. At this time, only a sufficient amoun...Read more
