A condenser is a component of a refrigeration system and belongs to a type of heat exchanger. It can convert gas or vapor into a liquid, and quickly transfer the heat in the tube to the air near the tube. The working process of the condenser is an exothermic process, so the condenser temperature is relatively high.
The power plant uses many condensers to condense the steam from the turbine. Condensers are used in refrigeration plants to condense refrigeration vapors such as ammonia and freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. During the distillation process, the device that converts the vapor into a liquid is also called a condenser. All condensers operate by taking away the heat of gas or vapor.
Gas passes through a long tube (usually coiled into a solenoid) to allow heat to be dissipated into the surrounding air. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, a heat sink with excellent heat conduction performance is often added to the pipe, and the heat dissipation area is enlarged to accelerate the heat dissipation, and the air convection is accelerated by the fan to take away the heat.
The general refrigeration principle of a refrigerator is that the compressor compresses the working medium from low-temperature and low-pressure gas to high-temperature and high-pressure gas, and then condenses into a medium-temperature and high-pressure liquid through a condenser. After being throttled by a throttle valve, it becomes a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid working medium is sent to the evaporator, which absorbs heat and evaporates in the evaporator to become low-temperature and low-pressure steam, which is sent to the compressor again to complete the refrigeration cycle.
The single-stage vapor compression refrigeration system is composed of four basic components: a refrigeration compressor, a condenser, an evaporator, and a throttle valve. They are connected by pipes in order to form a closed system, and the refrigerant is continuously circulated in the system. Flow, state change, and heat exchange with the outside world.
In the refrigeration system, the evaporator, condenser, compressor, and throttle are the four essential parts of the refrigeration system. Among them, the evaporator is a device that transmits cold energy. The refrigerant absorbs the heat of the object to be cooled to achieve cooling. The compressor is the heart and plays the role of sucking, compressing, and transmitting refrigerant vapor. Condenser is a device that releases heat, and transfers the heat absorbed in the evaporator to the cooling medium with the heat converted by the compressor work. The throttle valve has the function of throttling and reducing the pressure of the refrigerant, and simultaneously controls and adjusts the amount of the refrigerant liquid flowing into the evaporator, and divides the system into two parts: a high-pressure side and a low-pressure side. In the actual refrigeration system, in addition to the above four major components, there are often auxiliary equipment, such as solenoid valves, distributors, dryers, heat collectors, fusible plugs, pressure controllers and other components. They are designed to improve operation Economical, reliable and secure.
