Working Principle:
The working principle of the explosion-proof chiller is basically the same as that of the ordinary chiller, but a series of explosion-proof measures have been taken in the design and construction to ensure safe operation in hazardous environments. The following is the general working principle of explosion-proof chillers:
1. Cooling cycle: The explosion-proof chiller absorbs the heat generated in the equipment or process through the circulating medium (usually water or other cooling liquid), and takes it to the cooler for heat dissipation, and then the cooling medium circulates back to the equipment for cooling .
2. Compressor: The chiller contains a compressor inside, which compresses the refrigerant so that it becomes a high-temperature and high-pressure gas under high pressure.
3. Condenser: The high-temperature and high-pressure gas passes through the condenser, contacts with the cooling medium and releases heat, cooling the refrigerant and turning it into a liquid state.
4. Expansion valve: The liquid refrigerant enters the evaporator through the expansion valve. The function of the expansion valve is to reduce the pressure and temperature of the refrigerant so that it becomes a low-temperature and low-pressure evaporated gas.
5. Evaporator: The low-temperature and low-pressure evaporated gas passes through the evaporator, contacts the equipment or process to be cooled, absorbs heat and cools it down.
In the explosion-proof chiller, the key to the working principle is the explosion-proof design and construction. The following are
some common explosion protection measures:
- Explosion-proof electrical components: Use explosion-proof motors, switches, sensors, etc. to prevent explosions caused by electric sparks.
- Explosion-proof shell: The shell of the chiller adopts an explosion-proof design, which can withstand internal pressure and temperature, and prevent external flammable gases from entering the interior.
- Explosive gas discharge: The discharge of explosive gas is considered in the design of the chiller to release the explosion pressure beyond the safe range.
- Material selection: Use high temperature resistant, anti-corrosion and explosion-proof materials to ensure that the chiller can withstand and prevent explosion risks in hazardous environments.
The above is the general working principle and common explosion-proof measures of explosion-proof chillers. The specific working principle and design details may vary due to different explosion-proof standards and application requirements.

2. Compliance with explosion-proof standards: Explosion-proof chillers usually comply with specific explosion-proof standards and specifications, such as the explosion-proof standards of the International Electrotechnical Commission (IEC), the European explosion-proof standards (ATEX), etc. They are rigorously tested and certified for safe performance in explosive atmospheres.
3. Explosion gas discharge: Explosion gas discharge is considered in the design of explosion-proof chillers, so as to release the explosion pressure beyond the safe range and reduce the harm to equipment and personnel.
4. Temperature and pressure monitoring: Explosion-proof chillers are usually equipped with temperature and pressure monitoring devices, which can monitor the working status of the equipment in real time. Once the temperature or pressure exceeds the safe range, it will trigger an alarm or automatically stop to avoid potential danger.
5. High-temperature-resistant materials: Explosion-proof chillers use high-temperature-resistant materials, which can maintain structural stability and integrity in high-temperature environments and reduce safety hazards caused by high temperatures.
6. Overload protection: Explosion-proof chillers usually have an overload protection function. When the equipment is overloaded or fails, it will automatically stop or take other safety measures to protect the safety of equipment and operators.
In general, explosion-proof chillers have been designed and constructed with special safety considerations to ensure their safe performance in hazardous environments. These safety performance measures are designed to reduce the risk of fire, explosion and other hazardous events and to protect the safety of equipment, workers and the environment.
