The heat radiation of screw type water chiller and its treatment method: when the condenser heat is not good, the compressor efficiency is low, the running current is improved,
When the air cooled high pressure pressure rises to 24kg/cm2, the water cooled high pressure rise to 20kg/cm2, the compressor is protected by the high voltage switch,
Compressor stop running, bad heat dissipation and high pressure overload and display the fault code or fault indication.
Normal, cooling water temperature is not too high, the cooling tower fan pump is running, the valve of the cooling water valve is completely open (air cooling type please check
Check the radiator has a dirty block), more than the normal and then press the reset button to restart or shutdown normal operation. Such as frequent high pressure overload
As soon as possible, please arrange for cleaning condenser.
Screw type chiller unit youyou evaporator out of state for the gas refrigerant, compressor adiabatic compression into.
Pressure state. After being compressed gas refrigerant, in the condenser, isobaric cooling and condensation, the condensed into liquid refrigerant by throttle valve
Expansion to low pressure, into a gas-liquid mixture. The liquid refrigerant in the evaporator is absorbed by the heat of the cold material in the evaporator.
Gaseous refrigerant. Gaseous refrigerant through the pipeline to re-enter the compressor, the beginning of a new cycle. This is the four process of the refrigeration cycle, too.
Main working principle of screw type water chiller.
One, screw type chiller compressor using international brand, new efficient screw rotary compressor, than the general high efficiency of the compressor
Out of 20%-30%, and to obtain the European and American multinational patent IS9001 international certification quality.
Two, high efficiency 5:6 patent asymmetric rotor profile.
Three, the capacity can be controlled by four segment (100%-75%-50%-25%) or three type (100-66%-33%) and stepless control system.
Four, the 11 bearing and a thrust balance Gu combination design, greatly enhance the bearing life of 2.5-3.5 times.
Five, the high efficiency silicon steel sheet special groove design, and equipped with inside and outside of omni directional type designed to be cooled to flow, makes the compressor motor in any
The maximum efficiency can be played under the load.
