Since the 1970s, the working reliability of screw compressors has been continuously improved, therefore, it is widely used in refrigeration and air-conditioning engineering in the range of medium refrigerating capacity, and depends on high reliability and efficiency, successfully squeezed into the original piston compressor dominated by the smaller cooling range (750 kw below) . Screw compressor has been so successful, let's analyze its performance.
Solenoid valve is a valve using electromagnetic force. It is an on/off valve that controls the flow of refrigerant in response to power failure. Solenoid valves can be broadly divided into two categories:
Les vannes couramment utilisées dans les systèmes de réfrigération sont : robinet à soupape, papillon des gaz, soupape de sécurité, manomètre, clapet anti-retour, indicateur de niveau de liquide.
Before adjusting thermostatic expansion valve, must confirm that the equipment refrigeration abnormal is caused by the thermostatic expansion valve deviation from the optimal operating point, but not because of less freon, dry filter plug, filter, fan and other reasons caused by.
Sanheng est un fabricant professionnel de détendeurs, de détendeurs thermiques et de détendeurs de climatisation. Lorsque la température de la tête de la boîte à air diminue, P1
A refrigeration unit is a device used to realize a refrigeration cycle, which reduces the temperature and maintains a constant ambient temperature by absorbing heat. It is one of the most critical core components in a refrigeration system, and is therefore also known as the main unit of a refrigeration plant.
