Reason analysis of refrigeration compressor can not start or stop soon after start

1) First check the main circuit. Whether the power supply has power, whether the voltage is normal, whether the fuse has been blown due to starting overload, whether the air switch has tripped, whether the switch contacts are good, and whether the power supply is missing phase. Observe the voltmeter and ammeter when starting. When the small-scale refrigeration and air-conditioning equipment does not have an ammeter or electric meter, a multimeter or electric pen can be used to check the power supply. When the power supply voltage is too low, the compressor will not start.

How to solve the low cooling efficiency of low-temperature chillers

When the low-temperature chiller has a poor cooling effect, it means that the equipment is in high-efficiency operation, but there are very few cold sources, which cannot meet the actual needs of the company for a low-temperature environment.

How to solve if the air conditioner is not cooling

If it is not in the cooling state, we can adjust it to the cooling mode; if the dust accumulation of the air conditioner severely reduces the cooling function, we can find professional personnel to disassemble the evaporator, fan blade, and filter. Completely clean up; if it is because no refrigerant is added, then we can add refrigerant.

See the real chapter for details, small technology to solve big problems-talk about tunneling effect and its improvement

In the introduction of adsorption dryers, the term "tunneling effect" is often mentioned. So what exactly is "tunneling effect"? We call the phenomenon of uneven air distribution in the drying tower, rapid flow in the middle and slow flow at the edges as Rﰨ2䀀湠癒Vǜ
