The treatment method of chiller temperature is difficult to drop
As the temperature rises, or the frequency of use of the chiller is relatively high, it will cause the temperature of the chiller to be different to frop at a high level. If the service time of water-cooled chiller has reached more than half a year, then the operating temperature is too high, which is… Read more The treatment method of chiller temperature is difficult to drop
The working principle of chiller
The refrigerating working medium absorbs the heat of the cooled substance in the evaporator and vaporize into steam. The compressor constantly extracts the generated steam from the evaporator and compacts it. After compression, the high temperature and high pressure steam is sent to the condenser to release heat and condense into high pressure liquid to… Read more The working principle of chiller
Low pressure fault analysis of industrial chillers
The low pressure alarm of chillers and chillers is a common problem in the use of industrial chillers. There are several possible reasond for the failure. 1. There is leakage in the refrigeration system. When the control temperature f the normal temperature chller is above 5 degrees and the low pressure gauge is below 2… Read more Low pressure fault analysis of industrial chillers
The difference between air-cooled chiller and water-cooled chiller
The functions and refrigeration methods of air-cooled chiller and water-cooled chiller are the same. The overall structure and operation curcult are the same except for the condenser. The air cooled chiller adopts fin type condenser, which takes away the heat of refrigerant by forced air flow directly from the fan. Water-cooled chiller adopts shell and… Read more The difference between air-cooled chiller and water-cooled chiller
Reason for serious insufficient heat exchange in evaporator
There are probably the following reasons for insufficient heat exchange in the evaporator. First, the evaporator water flow is insufficient. The main factors that cause this phenomenon are that the pump is broken or there is a froeign body in the pump impelier, ot the water pump inlet pipe leaks caused by insufficient water flow.… Read more Reason for serious insufficient heat exchange in evaporator
The working priciple of chillers
The chiller uses the limited refrigerant int he closed refrigeration system, repeatedly compressing, condensing, expanding and evaporating the refrigeratn, and constantly absorbs heat and vaporizes in the evaporator to refrigerate and cool down. The chiller is composed of compressor, condenser, evaporator, evaporator, expansion valve, circulating water pump, electric control system and rack, etc. In the… Read more The working priciple of chillers
The advantages and disadvantages of the different types of chiller
Screw chiller Screw chiller is a unit that uses various types of screw compressors as the main engine. It is a combined refrigeration device composed of screw compressor, condenser, evaporator, thermal expansion valve, oil separator, automatic control components and instruments. The typical cooling capacity is from 700KW to 1000KW. Advantages: Simple structure, less parts, less… Read more The advantages and disadvantages of the different types of chiller
The working principle of chemical refrigeration thermostal
The thermal power and the pressure and flow of the heat transfer medium are also factors to be considered in the selection of thermostats for refrigeration and heating for the chemical industry. Different raw materials have different characteristics, and they have different processing technology chatacteristics. Chemical refrigeration and heating thermostat is more and more popular… Read more The working principle of chemical refrigeration thermostal
From what aspects should we consider the use of circulating chillers?
Circulating coolers are a popular choice for temperature-critical applications because they provide stable temperature control, constant flow and constant pressure control. Many process heating systems require cooling and heating. For example, many conveyor heating zones have cooling zones. Injection molding requires a lot of heat dissipation. And the reactor is usually jacketed with cold water.… Read more From what aspects should we consider the use of circulating chillers?
