Overview

Product Details

The enclosed high and low temperature integrated machine has the characteristics of reasonable structure, easy operation, and good stability performance. It adopts a fully enclosed pipeline design and uses a plate heat exchanger to reduce the demand for heat transfer fluid while improving the heat utilization rate of the system, achieving rapid temperature rise and fall. The thermal conductive medium is in a closed system with an expansion container, and the thermal conductive medium in the expansion container does not participate in circulation. Whether it is high or low temperature, the temperature of the expansion tank is from room temperature to 60 degrees, which can reduce the risk of moisture absorption and volatilization of the thermal conductive medium during operation. Therefore, it is widely used in colleges and universities, environmental protection, biochemistry, medical care, chemical engineering, scientific research and other fields.

Performance characteristics:

1. There are three systems: refrigeration system, heating system, and pre cooling system. The three systems can be used continuously or separately.

2. Fast heating and cooling, capable of continuous temperature rise and fall.

3. Wide temperature control range, no need to replace the thermal medium throughout the process, and low consumption of thermal medium.

4. A fully enclosed circulation system ensures that the heat transfer fluid is not easily volatile or oxidized at high temperatures, and is less likely to absorb moisture from the air at low temperatures, which can extend the service life of the heat transfer fluid.

5. High temperature cooling and refrigeration function, which can directly reduce temperature from high temperature (such as from 200 ℃).

6. The refrigeration heat exchanger adopts a fully brazed plate heat exchanger, which occupies a small space and has high heat transfer efficiency.

7. Liquid level display function, monitoring the liquid level at any time to avoid liquid shortage.

8. Multiple protection functions such as high temperature cut-off, emergency stop, delay, leakage, overcurrent, and overheating fully ensure safe use.

9. The condensation and pre cooling methods are air cooling, which saves water resources.

An important part is to provide accurate operating conditions, as multiple reaction kettle refrigeration and heating control systems TCU high and low temperature integrated machines are produced according to actual conditions, and accurate information needs to be provided when purchasing.

The function of the fully enclosed pipeline design for high and low temperature integrated machines is:

① The liquid circulation of the entire system is airtight, and the system is equipped with an expansion container. The expansion container and liquid circulation are adiabatic and do not participate in the liquid circulation, but are only mechanically connected, regardless of whether the temperature of the liquid circulation in the expansion container is high or low. The medium is always kept at room temperature, and since the entire liquid circulation is a closed system, it will not absorb water vapor at low temperatures and will not produce oil mist at high temperatures.

The entire closed liquid circulation system will not have oil mist evaporation at high temperatures, and the heat transfer oil will not be oxidized or brown. At low temperatures, it will not absorb water vapor from the air, extending the service life of the heat transfer oil and reducing its operating costs.

The process of a closed high and low temperature integrated machine is as follows:

The refrigerant is adiabatically compressed by the compressor to a higher pressure and consumes work to increase the exhaust temperature;

The refrigerant exchanges heat with the surrounding medium isothermally through the condenser and transfers the heat to the surrounding medium;

The refrigerant expands adiabatically through the shut-off valve and takes effect, causing the temperature of the refrigerant to decrease;

The refrigerant absorbs heat from objects at higher temperatures through the evaporator, thereby reducing the temperature of the cooled object;

Repeat this cycle to achieve cooling, and the design of the refrigeration system adopts energy regulation technology;

An effective processing method can ensure that the energy consumption and cooling capacity of the refrigeration system can be effectively reduced under normal operation of the refrigeration unit, and the operating cost of the refrigeration system in the testing room can be adjusted to a more economical state.

② Adopting PID intelligent control, automatically adjusting power output according to chemical process technology, accurately controlling the temperature of the reaction process, and meeting the requirements of temperature changes in the reaction process.

③ Specially customized circulation pump with high flow rate, low pressure and heat generation, high heat transfer efficiency, low system resistance, low heat generation of the pump system, and low system energy consumption.
