The refrigeration equipment of a refrigerated semi-trailer mainly includes a refrigeration unit, heat exchanger, circulating fan, temperature sensor, and other accessories. Its working principle is to use the refrigeration unit to cool the air inside the cargo compartment or the water or other medium flowing through the heat exchanger to control the temperature inside the cargo compartment.
Specifically, the working process of the refrigeration equipment is as follows:
1. Refrigeration unit: The refrigeration unit is one of the cores of the refrigeration equipment of a refrigerated semi-trailer. Its function is to cool the air inside the cargo compartment or the water or other medium flowing through the heat exchanger. According to different refrigeration methods, the refrigeration unit can be divided into air cooling and liquid cooling types.
2. Heat exchanger: The heat exchanger is an important component of the refrigeration equipment of a refrigerated semi-trailer, mainly responsible for transferring the refrigerant between the cargo compartment and the external environment. Specifically, the heat exchanger carries the heat inside the refrigerated vehicle to the outside through the refrigerant and provides refrigerant from the outside to maintain the constant temperature inside the cargo compartment.
3. Circulating fan: The circulating fan is a device used to circulate the air inside the cargo compartment, which can continuously circulate the air inside the cargo compartment to ensure even distribution of temperature and humidity.
4. Temperature sensor: The temperature sensor is a device used to monitor changes in the temperature inside the cargo compartment. It can detect the temperature inside the cargo compartment in real-time and transmit the temperature data to the control system. Based on the feedback from the control system, the refrigeration equipment can adjust the temperature in a timely manner to meet the requirements of different types of goods.
In summary, the refrigeration equipment of a refrigerated semi-trailer achieves accurate control of the temperature and humidity inside the cargo compartment through the coordinated action of the refrigeration unit, heat exchanger, circulating fan, temperature sensor, and other accessories. This ensures the quality and safety of goods during transportation and meets the requirements of different types of transportation needs
