Selection of Oil Mold Temperature Controller:

The selection of the Oil Mold Temperature Controller should be based on the heat generation of the heat-generating components and the control requirements to choose the model:

1. Select a chiller with a matching cooling capacity - the cooling capacity of the chiller should be greater than the heat to be cooled.

2. Select a chiller with a matching water flow rate - The water flow rate needs to be in line with the required control flow rate. Different flow rates will affect different temperature control accuracies.

3. Select a chiller with a temperature control mode and precision that match - Different temperature control modes and precisions directly affect whether the chiller is suitable for operation.

4. Seek out a reliable supplier - only chillers from reliable manufacturers will receive sufficient support.

Common calculation methods of Oil Mold Temperature Controller:

The calorific value is calculated by the temperature difference between the inlet and outlet of the cooling water (oil)

Q = SH * De * F * DT / 60

Q: Calorific value in KW

SH: The specific heat of water is 4.2KJ/Kg*C (4.2 kilojoules /Kg* Celsius), and that of oil is 1.97KJ/Kg*C (1.97 kilojoules/kg * Celsius).

De: Specific gravity: The specific gravity of water is 1Kg/L (1 Kg/L), and that of oil is 0.88Kg/L (0.88 kg /L).

F: Flow rate LPM (L/min L/min)

DT: Temperature difference between the inlet and outlet of cooling water (oil) (outlet temperature - inlet temperature)

Note: "/ 60" is used to change the flow rate from liters per minute to liters per second; 1kW = 1kJ/s;

Supplementary explanation:

The cooling capacity of the Oil Mold Temperature Controller varies with the ambient temperature and the outlet water temperature.

2. The actual heat generated by the equipment may also vary due to different workpieces, molds, parameters, etc.

3. After using the Oil Mold Temperature Controller, the temperature drops. The temperatures of the connecting pipelines, water tanks, oil tanks, molds, main shafts, and the surface of the equipment will be lower than the ambient temperature. Therefore, heat will be absorbed, resulting in an increase in load.

4. In the practical application of industrial cooling, in many cases, it is impossible to accurately calculate using the above methods. At such times, estimation can only be made through empirical data, analogy with similar equipment, and other methods.

5. Any calculation method may have deviations, resulting in the actual selected refrigeration units being either too large or too few. Therefore, the above method is for reference only.

The requirements for small water chillers specifically designed for laboratories are relatively higher than those for ordinary water chillers in terms of temperature control accuracy and cooling capacity. This is related to the precision of commonly used laboratory instruments and the rigor of experimental data. When purchasing a small water chiller specifically designed for laboratories, the following two points should be noted:

Selection of quality for small water chillers: The quality of small water chillers produced by different water chiller manufacturers also varies. After all, small water chillers are classified into different grades. The refrigeration compressor is the main indicator that affects the performance of small water chillers. Some water chiller manufacturers, in order to control the overall production cost during the production process, use lower-quality products for key parts such as the refrigeration compressor. Even refurbished compressors are used, which seriously affects the later usage efficiency of small water chillers and may cause deviations in experimental data.

2. Control procurement costs: Under the premise of ensuring the quality of small water chillers, purchasing small water chillers that suit you at a relatively high cost performance can achieve the goal of reducing costs and meet the laboratory's needs with the least amount of funds.
