The purpose of jet enthalpy technologyTo understand the jet enthalpy increase technology, we must clarify the purpose of this technology: it is to solve the problem of low temperature heating.The air conditioner extracts heat from the outdoor air in winter and sends the heat to the room. This is the

   Common fault phenomenon and cause analysis of Copeland scroll compressor   I. Copeland refrigeration compressor units are widely used in refrigeration equipment such as cold storage. During the use process, there are mainly the following four kinds of failure phenomena:  1. The

   Advantages and disadvantages of air-conditioning water system and multi-line fluorine system   I. Introduction of multi-line fluorine:   There are two main types of multi-connection. One is to integrate the outdoor units of two to four household machines into one housing, and th

Multi-line blowing, air tightness, vacuum drying, refrigerant operation and precautions  1.1. Blowing of copper pipes  2,1, role:  Use pressure gas to flush pipes (raw material pipes or welded components) to remove dust (solid impurities cannot be blown out,

Vapor compression refrigerationPrinciple: In the vapor compression refrigeration cycle system, the compressor inhales low-temperature and low-pressure refrigerant vapor from the evaporator, adiabatically compresses it into a high-temperature and high-pressure superheated vapor, and then presses it i

Reasons for compressor thermal protectionToo much refrigerant in the air-conditioning system leads to excessive system pressure, which leads to thermal protection of the compressor; excessive pressure of the air-conditioning system pipeline blockage leads to thermal protection of the compressor; a s

Many brands of chiller refrigeration compressors will have overcurrent protection in the machine's own protection function. Whether it is from the external power supply or the operation of the chiller refrigeration compressor itself, the excessive current of the chiller is more frequent. What ha

The cooling capacity of the chiller is directly related to the operating status of the system. For compressors with the same structure, the same speed, and the same refrigerant type, due to changes in operating conditions, cooling capacity and energy consumption, the operation management is also dif

1.the role of refrigeration oil(1) LubricationIt can lubricate the surfaces of moving parts of the compressor, reduce resistance and friction, reduce power consumption and prolong service life.(2) cooling effectIt can take away the heat generated by the friction of the moving surface in time t

When the motor burns out, the contactor must be checked. Contactors and phase loss/voltage anomalies are an often-forgotten cause of motor damage. Today we will talk about the problems of contactor and power supply phase loss and abnormal voltage, and hope to help everyone.1. AC contactorThe AC cont
