The following is a detailed description of a refrigeration and heating temperature control system with a temperature range of 20°C to 150°C and a working medium flow rate of 50L/min:

System requirements:

1. Temperature range:

•Minimum temperature: 20°C

•Maximum temperature: 150°C

•Temperature control accuracy: ±1°C or higher is usually required

2. Portata:

•Flow rate of working medium (hydraulic oil): 50L/min3.

Other requirements:

•Automation control

•Data recording and monitoring

•Safety protection measures

•Efficient energy saving.

Selection considerations

1. Heating power calculation:

•Calculate the required heating power based on the flow rate and temperature rise requirements.

The formula is as follows:
Where: •(P) is the heating power (kW)
•(C_p) is the specific heat capacity of the hydraulic oil (kJ/kg·K)
•(m) is the flow rate (kg/s), which can be calculated by density and volume flow rate

• ▲ is the temperature rise (K)

2. Calculation of cooling capacity:

• Calculate the required cooling capacity based on the flow rate and temperature drop requirements.

The formula is similar:
Where: •(Q) is the cooling capacity (kW)
•(C_p) is the specific heat capacity of the hydraulic oil (kJ/kg·K)
•(m) is the flow rate (kg/s)

• ▲ is the temperature drop (K)

3. Pump selection:

• Select a pump suitable for hydraulic oil to ensure that its flow rate and pressure can meet the system requirements.

4. Pipeline and valve selection:

• Select high temperature and corrosion resistant pipeline and valve materials to ensure long-term stable operation of the system.

Summary To design a refrigeration and heating temperature control system with a temperature range of 20°C to 150°C and a working medium flow rate of 50L/min, it is necessary to comprehensively consider the heating and cooling capacity, flow rate, temperature control accuracy and safety protection measures. By rationally selecting the heating unit, refrigeration unit, circulation pump, temperature control system and safety protection device, it is possible to ensure that the hydraulic system operates under ideal temperature conditions and improve the efficiency and reliability of the system. In the specific selection and design process, it is recommended to consult a professional equipment supplier or engineer to ensure the performance and safety of the system.
