How to solve the problem of hot water chiller unit

Screw chiller cooling and poor processing method: when the condenser cooling adverse, the efficiency of the compressor low operating current is increased, when the air pressure rose to 24kg/cm2, water-cooled pressure rose to 20kg/cm2 compressor by protection of high voltage switch to jump off the compressor stops running, poor heat dissipation and high pressure overload and display fault code or fault instructions, at this time, please view the normal cooling tower circulating water, cooling water temperature is too high, cooling tower fan water pump is running, cooling water valve is fully open (air-cooled please check the radiator is a dirty block), above normal again press the reset button, or shutdown restart can operate normally. If there is often a high pressure overload, please arrange for the cleaning condenser as soon as possible.

Screw type chiller unit youyou evaporator out of state for the gas refrigerant and compressor adiabatic compression into state of high temperature and high pressure. After being compressed gas refrigerant, in the condenser, isobaric cooling and condensation, condensed into liquid refrigerant, through the throttle valve was expanded to a low pressure into gas-liquid mixture. The liquid refrigerant in the evaporator is absorbed by the heat of the cold matter, and becomes a 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, and also the main working principle of the screw type water chiller.

One, screw type chiller compressor using international brands, new efficient screw rotary compressor, than the general efficiency of the compressor out of 20%-30%, and the European and American multinational patents IS9001 international certification of 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 the omni-directional design cooling flow to and makes the compressor motor in any load can play a maximum efficiency.
