Auxiliary accessories commonly used in low-temperature chillers, including water flow switch, pressure controller, differential pressure controller, temperature controller and solenoid valve, as well as a brief introduction to three types of refriger...

Understand the impact of moisture on air-cooled screw chillers, you can target the chiller equipment to take moisture and waterproof measures to avoid major problems affecting the normal progress of industrial production. Specific how to "protect" ai...

Under normal circumstances, the antifreeze replacement cycle of water-cooled machines is recommended to be changed once every six months, or once a year. Because the antifreeze will deteriorate after a long time, the antifreeze will become more corro...

1、Refrigerant system is overcharged with refrigerant Cause: Excessive refrigerant causes the exhaust pressure to rise significantly beyond the normal value. Treatment: Stop the machine and discharge the excess refrigerant in the high pressure v...

A, screw type ice and water machine compressor failure causes: 1, the compressor AC contactor on the overload protector action. 2, the compressor capacitor burned out (single-phase). 3, check whether the compressor coil winding is normal, th...

The main role of the screw chiller is to provide chilled water to the equipment products to achieve the purpose of cooling. And after we buy the screw chiller back, in the process of using, familiar with the safety operating procedures is an essentia...

Calculate heat generation Q=SH×De×F×DT/60 by the temperature difference between inlet and outlet of cooling oil Q: heat generation KW (Note: the heat generation of 1P oil cooler is about 2.5KW) SH:Specific heat of specific heat oil is 1.97KJ/Kg...

The industrial refrigeration unit is an environmentally friendly product without compressor, cold coal and pollution. It uses the principle of evaporative cooling of the whole fresh air outside and convection air exchange with the room to achieve the...

The chiller cooling principle is: when the fan runs into the cavity to generate negative pressure, so that the air outside the machine flows over the surface of the porous wet curtain forcing the dry bulb temperature of the air over the curtain to dr...

1、The principle of low-temperature refrigeration unit Low-temperature refrigeration machine because of its key components, the unit from the evaporator out of the state of the gas refrigerant; by the compressor after adiabatic compression, into a ...

Water-cooled ice and water mechanism cooling principle: the refrigerant mass in liquid state in the evaporator heat absorption refrigeration, low-temperature liquid absorption latent heat of gasification into refrigerant gas is compressed and compres...

Air-cooled screw chiller points of note: 1, screw chiller temperature range when choosing an industrial chiller/freezer, the first thing you should consider is the temperature requirements of the plant. The level of temperature produced has extrem...
