As a component of the refrigeration system, the condenser is a type of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a fast way. The working process of the condenser is an exothermic process, so the temperature of the condenser is relatively high.
The gas is passed through a long tube (usually coiled into a solenoid) to dissipate heat into the surrounding air. Metals such as copper conduct heat well and are often used to transport steam. In order to improve the efficiency of the condenser, a heat sink with excellent thermal conductivity is often attached to the pipeline to increase the heat dissipation area to accelerate the heat dissipation, and the air convection is accelerated through the fan to take away the heat.
The refrigeration principle of the general refrigerator is that the compressor compresses the working fluid from low temperature and low pressure gas into high temperature and high pressure gas, and then condenses into medium temperature and high pressure liquid through the condenser. After being throttled by the throttle valve, it becomes low temperature and low pressure liquid. The low-temperature and low-pressure liquid working medium is sent to the evaporator, where it absorbs heat and evaporates 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, a throttle valve and an evaporator. They are connected in turn by pipes to form a closed system, and the refrigerant circulates continuously in the system. Flow, state change occurs, and heat is exchanged with the outside world.
