The necessity of installing safety devices in the freezer and the standard

The cold compressor of the freezer and its pipes, valves, etc. work under different pressures. When the refrigerant circulates in the system, an accident may occur if improper operation results in circulation under abnormal pressure. During operation, the operator must not only strictly abide by the operating regulations, but also have more sophisticated safety equipment. Because these safety devices are operators, some safety devices can also automatically solve the problem.
Therefore, sophisticated safety equipment is to ensure the safe operation of the freezer, but also one of the necessary conditions to prevent accidents. The higher the automatic failure prevention capability of the safety device, the less likely the accident will occur, so it is very necessary to install, improve, and perfect the safety equipment of the air-conditioning device. For example, in refrigeration compressors, relays that control hydraulic pressure, steam absorption pressure, and exhaust pressure are automatic safety protections against cold compressor failures and accidents, which act as automatic controls for the safe operation of machines.
Freezer
The installation of safety devices can only prevent accidents related to the refrigeration cycle, and cannot prevent failures and accidents caused by insufficient mechanical equipment materials and processing technology. Therefore, first of all, the quality and mechanical characteristics of the manufacturing materials used in the freezer structure must be the general standards for mechanical manufacturing. The mechanical properties of ammonia and lubricating oil must be stable and must be able to resist the work. Different pressure and temperature changes.
Make the correct adjustments. Ensure the quality of freezer and other mechanical equipment. Sophisticated safety devices and safe operation make the three perfectly coordinated together, which helps prevent accidents when machines and equipment are operating safely. Deterioration of one of the above conditions may cause malfunction or accident. In addition, some safety devices, like the liquid level indicator angle valve of the device, do not expand the accident when the accident occurs.
With the deepening of environmental awareness, more and more energy-efficient green electrical equipment is used. Energy-efficient refrigerators also need more complete cooling protection to reduce external heat, including appropriate enhancement of thermal insulation foam layer, improvement of foam materials Process and improve the door sealing structure. So, which freezer is really an energy-efficient freezer? I now share with you some of the main features of energy-efficient refrigerators. Please pay attention to this when buying a freezer:
Freezer
Energy-saving refrigerators generally have the following main features:
1. Apply new energy-saving working medium. According to different operating media, the power consumption of the freezer is different, and it is directly related to the cooling effect of the freezer. Like the environmentally friendly and energy-saving R600A refrigerant, the cooling effect has been significantly improved.
2. Use high-efficiency compressors. The compressor is the heart of the freezer box and the main energy-consuming part of the freezer. The use of a high-efficiency compressor is the simplest and most effective measure for energy saving in the freezer.
3. Check the cold air protection measures of the freezer. In order to maintain the required low temperature, the refrigerator adopting the above-mentioned energy-saving measures mainly uses electricity to overcome the temperature rise in the freezer in order to maintain the required low temperature.
4. Is to achieve high energy efficiency. The energy efficiency ratio is the ratio of the actual cooling capacity to the actual input power during the cooling operation of the refrigerator under rated conditions and specified conditions. The higher the energy efficiency of the freezer, the more power saved when the cooling capacity is the same.
