Liquid hammer is extremely destructive. It can shatter the scroll plate in a short period, damage the compression chamber, and the fragments may scratch the motor insulation layer, leading to short circuits. Excessive refrigerant charge: Causes massive liquid return in the system (more likely to ...

In 2025, with the advent of the traditional peak sales season for the refrigeration industry, the third-generation refrigerant market has once again ignited a new wave of price surges, drawing heightened market attention to the performance of leading industry enterprises. According to authoritative ...

What is a constant temperature cold storage? Is it the constant temperature mode of an ordinary cold storage? The difference between a constant temperature cold storage and an ordinary cold storage Constant temperature cold storage is one of the common types of cold storage installations and is ...

Summary of common failures of thermal expansion valves Thermal expansion valves are a control element widely used in air conditioning, refrigeration and other fields, mainly responsible for realizing pressure regulation and flow control of refrigerants. Many friends who do refrigeration know that ...

1. The cold storage has a large loss of cold due to poor insulation or sealing performance. The poor insulation performance of the cold storage is due to the insufficient thickness of the insulation layer of the pipeline, the insulation wall of the warehouse, etc., and the poor insulation and ...

Common components and functions of cold storage refrigeration system 1. Compressor: It plays the role of compressing and driving the flow of refrigerant in the refrigerant circuit, and is the power of the refrigeration system. 2. Condenser: It is one of the main heat exchange equipment in the cold ...

Working principle of screw compressor Inhalation process: As the rotor rotates, the gear volume increases. Gases from the evaporation system enter the gear volume through the suction holes. When the rotor rotates to a certain angle, the gear passes through the suction hole and the suction process ...

RefComp Screw Compressor working principle: 1. Inhalation process When the rotor rotates, the inter-tooth volume formed by the main and auxiliary rotors gradually expands, and this volume is only communicated with the suction port, and the outside air is sucked into the inter-tooth volume. When the ...

Danfoss Pressure Switch. Danfoss pressure switch are one of the more commonly used fluid control components. When dealing with gases or liquids, it is almost always necessary to control their pressure. They are usually used in paper machines, air compressors or pump sets. Danfoss pressure switches ...
