The electric refrigeration unit is the core component of the electric refrigerated truck. It is mainly used to maintain the low-temperature environment in the compartment and ensure the freshness or freezing of goods. The following is a detailed introduction to electric refrigeration units:

1. Electric refrigeration unit's component:

Evaporator (indoor unit): Responsible for releasing cold air in the cabin and reducing the temperature.

Condenser (outdoor unit): Works in conjunction with the evaporator to remove heat from the cabin through the circulation of refrigerant.

Compressor: It is the power source in the refrigeration cycle. It drives the refrigerant to circulate in the system to achieve the refrigeration effect.

Refrigerant (such as Freon): As a refrigerant, it circulates in the system to complete the process of absorbing and releasing heat.

Copper tube: connects the evaporator and condenser to form a channel for refrigerant circulation.

Thermostat: Used to control the temperature in the cabin to ensure it is within the set range.

2. Electric refrigeration unit’s working principle:

The compressor drives the refrigerant to circulate in the system, and the refrigerant absorbs heat in the evaporator and turns into low-temperature and low-pressure gas.

The low-temperature and low-pressure gas is compressed into high-temperature and high-pressure gas by the compressor, and then enters the condenser.

In the condenser, the high-temperature and high-pressure gas dissipates heat to the outside world and turns into a high-temperature and high-pressure liquid.

The high-temperature and high-pressure liquid passes through the throttling device (such as an expansion valve) and becomes a low-temperature and low-pressure liquid, and then enters the evaporator again to complete the cycle.
