The problem of frosting in evaporator for cold room storage Mar 24, 2021
Many of my friends will encounter such a problem,Starting from the return port of the compressor, frosting toward the evaporator for cold room storage. Frost begins to form at the air return, which is mainly analyzed from the following two aspects: 1）. Refrigerant The reason is that too much refrigerant enters the air cooled evaporator, resulting in incomplete evaporation, so the return pipe is st...
Reasons for common failures of refrigeration system (1) Apr 13, 2021
1. Liquid back For refrigeration systems that use expansion valves, liquid return is closely related to the improper selection and use of expansion valves. Excessive selection of the expansion valve, too small superheat setting, incorrect installation of the temperature sensing bulb, damaged adiabatic dressing, and failure of the expansion valve may cause liquid backflow. For a small refrigeration...

The installation environment and maintenance of air-cooled evaporator May 03, 2021
The location and environment of the air-cooled evaporator inside the cold storage will affect its operation. Generally, the air-cooled evaporator near the cold storage door is prone to condensation and frost. Although the air cooler can automatically heat and defrost at regular intervals, if the door is opened too frequently, the opening time is too long, the time and quantity of hot air entering ...

How does one condensing unit supply multiple cold storages May 31, 2021
A refrigeration system in which a compressor needs to provide cooling to several warehouses with different temperature requirements at the same time is called a cold storage refrigeration system with one machine. According to refrigeration requirements, it is always desired that the high-temperature storage has a higher evaporation pressure, and the low-temperature storage has a lower ...
Daily maintenance of freezing and cold storage Jun 05, 2021
1. Frequently check and confirm whether the voltage of the power supply meets the requirements, the voltage should be 380V±10% (three-phase four-wire). Whether the protection function of the main power switch is normal and effective. 2. The electrical equipment of the cold storage equipment should be protected from moisture to avoid electric shock accidents caused by electric leakage. 3. The elect...

Summary of common problems in cold storage Sep 01, 2021
The installation of refrigeration system equipment and refrigerant pipelines, even the overall design of the cold storage and the daily use of the cold storage, must be done in strict accordance with the specifications. Any irregular design, installation, or use or maintenance will cause the refrigeration system to operate. Bad, and even cause malfunction and damage to the machine. 1. The refriger...

The relationship and adjustment of the four major components of the refrigeration system and the refrigeration capacity Sep 08, 2021
Because the refrigeration capacity of each cold storage refrigeration equipment will change under different working conditions, some increase, some decrease, so a certain margin is reserved in advance in the design to prevent it under certain operating conditions During operation, the cooling capacity of the entire device cannot be brought into full play due to the excessive reduction in the cooli...

Combined cold storage cooling method Sep 17, 2021
1. There should be no influence of various man-made heat flows around the library. The library body should be closed, the lighting in the library should be extinguished, and the electric heater should be used for preheating. The test can be performed only after the temperature in the warehouse reaches 32°C and stabilizes for 1 hour. 2. The temperature in the cold storage should be maintained at 32...

Cold storage condensing unit installation and commissioning Sep 27, 2021
1. Installation of the cold room evaporators 1). When choosing the position of the lifting point, first consider the best position for air circulation, and secondly, consider the structural direction of the library body. The clearance between the air cooler and the library board should be greater than the thickness of the cold room evaporators. 2. Group installation of cold room condensing u...

Refrigeration system professional vocabulary and explanation Oct 06, 2021
ONE，Refrigeration system professional vocabulary 1. Heat Heat is a form of energy. If the object is heated, the heat is sucked in; if it is cooled, the heat is discharged. The international unit is Joule (J). Commonly used units: kJ (kilojoule), BTU (British thermal unit), kCal (kcal) 2. Cooling capacity A unit of time, the heat taken away from the air-conditioned place by the air-conditioning uni...
