What should be Paid Attention to When Starting up the Reactor Refrigeration and Heating System?

The reactor refrigeration and heating system adopts a fully enclosed pipeline design and a plate heat exchanger, which reduces the demand for heat transfer fluid and improves the heat utilization rate of the system to achieve rapid temperature rise and fall. The heat transfer medium is in a closed system with an expansion vessel. The heat conduction medium in the expansion vessel does not participate in the circulation. Whether it is high temperature or low temperature, the temperature of the expansion tank is from room temperature to 60°C, which can reduce the absorption of water and volatilization of the heat transfer medium during operation. risk.

It adopts compressor refrigeration and high-pressure linkage heating technology, or direct heating with heating wire, and is controlled in real time by the advanced control system to meet the requirements of using cold water or hot water, maintain the water temperature at the set state, low vibration, low noise, and high energy efficiency ratio. The temperature control range is -150°C-350°C, with cooling and heating functions to meet different temperature requirements under different needs. Adopting compressor combination technology, the refrigeration circuit is started in a time-sharing dislocation, reducing interference to the power grid, stably exerting the performance of the compressor, and fully automatic temperature control, which can meet continuous operation 24 hours a day.

What should be paid attention to when the reactor refrigeration and heating system is started for the first time?

1. When starting up for the first time, press the power button and there is no display: the fuse in the power socket is broken, unplug the power cord, take out the fuse and replace it with a new one; Put the air switch in the “ON” state to solve the problem.

2. After turning on the machine for the first time or after a long period of non-starting, turn on the “circulation” button, the water pump does not turn or there is no circulating water, and the “circulation” indicator light is on: check whether there is a dead knot in the external hose, and untie the dead knot; there is a lot of air or scale inside the pump , or the long-term non-use of the water pump leads to a decrease in the lubrication of the rotor, making it difficult to start the water pump. It is necessary to unplug the power supply, open the cover of the device, remove the rubber disc directly behind the motor rotor, use a flat-head screwdriver to hold the motor rotor and move it left and right, and the motor can be restarted; directly replace the water pump.

3. The refrigeration system does not start: the refrigeration button is not turned on, turn on the refrigeration button; the circuit board is faulty, replace the circuit board; the compressor is faulty, and a professional inspection is required.
