Change the control settings of the method, the response as soon as possible in the process of the system lags behind, be the smallest system overshoot. Controlled by two PID (PID is a variable in each group) control loop structure, known as the two sets of control loops: the main circuit and from the circuit, the main control loop from the loop output as the settings.

Closed circulation system

The whole system is full closed circulation, there is no oil mist at high temperature and no water vapor at low temperature, pressure do not rise up when system is running. The system will supply oil automatically at low temperature.

heating

 Heating max output power

 The heater has triple protection and independent temperature limiter to ensure the safety of heating system.

The power is greater than 15KW with a voltage regulator, and the heating power output control adopts 4-20ma linear control.

Cooling capacity

The power of taking away the heat at different temperature

Circulation flow rate and pressure

  Lower than 75L/min, use Lneya Magnetic pump

Higher than 75L/min use Ultra wide temperature high energy efficiency centrifugal pump.

  Pressure selection: 2bar 3bar 5bar 8bar(small power equipment can not customize)

 The greater the pressure, the greater the power of the motor, which will increase the system load and reduce the cooling capacity of the system.

Impact and Solution of Excess Exhaust Temperature of Industrial Chiller Units

Industrial water chiller compressor exhaust temperature determines whether the equipment can stably and efficiently run. The common problem of compressor is excess exhaust temperature. Once the situation appears, it is easy to make industrial chiller high pressure and high temperature, overload, reduced working efficiency and poor industrial water chiller compressor refrigerating capacity. It can also lead to other problems. So how to reduce the exhaust temperature of industrial water chillers and cool the compressor, we are the experts to develop water chiller refrigeration system 320/420 w / 430 w experts, so today we will recommend a few solutions for you:

Increase cooling water flow and heat ventilation of water tank and water tower.
Air-cooled water tank of industrial cold water machine and cooling water in industrial cooling towers are to cool the condenser and transfer heat which can take away the heat generated by the compressor work. If you can guarantee the cooling water flow rate and air cooling industry cold water machine water tanks, water chiller water tower cooling ventilation ability, you will keep cooling water temperature to within the limits defined, so as to maximize the cool the compressor.

Reduce the exhaust temperature of the refrigeration compressor directly.
You can start from decreasing compression ratio and the load of the compressor. Lower compression ratio will make compressor low efficient, but it can solve the problem of excess exhaust temperature of
compressor.
