Troubleshooting of refrigeration system failure of material aging test equipment at low temperature
Regular maintenance work for the material low temperature and high temperature aging test system, and troubleshooting of the refrigeration system is also very important. Here are a few tips. 1. Exhaust at double high pressure, heat dissipation may be problematic. When it is detected that the high and low pressure of the system are higher than normal, it is usually because there is air in the system or excessive refrigerant is added. At this time, it is necessary to re-evacuate and add proper...

What should I pay attention to when choosing an evaporator for an ultra-low temperature chiller?
The evaporator in the ultra-low temperature chiller is one of its four major components, so performance is more important. The selection of ultra-low temperature chillers needs to pay attention to the influence of liquid level on the evaporation temperature. Due to the influence of the height of the refrigerant liquid column, the evaporation temperature at the bottom of the flooded evaporator is higher than the evaporation temperature of the liquid surface. The evaporation temperature of diff...

What references are needed for the selection of reactor temperature control system?
The heating power selection of the reactor temperature control system is roughly based on the size of the reactor. The reactor temperature control system is a constant temperature device used to heat and cool the reactor. When selecting, the two important parts are heating power and pumping power. This is related to the accuracy of the reactor temperature. To select the power of the reactor temperature control system, the following parameters need to be provided: 1. The size of the reactor ...

What do the fault codes of air-cooled chillers mean
Generally, people will see 2 areas on thecontrol panel of the device, namely PV area and SV area. The first oneexpresses the specific temperature, and the latter one is for setting thetemperature. When a fault occurs, PV displays the number of the informationfault and SV displays the name of the information fault.For example, the number of the informationfault displayed in the PV area is 1, and the name of the information faultdisplayed in the SV area is Err01. The reason is maintenance...
