What is the working principle of the condenser

The condenser, as we can know from its name, is the part that cools the Water Cooled Condenser into a liquid refrigerant! Its most important role is the heat exchange of the complete refrigeration system. The condenser is a heat dissipation device in the air conditioner, which radiates the heat of the refrigerant in the compressor compression process to the outer space of the vehicle, so that the high temperature and high pressure gas from the compressor becomes a medium temperature and high pressure liquid.

Water Cooled Evaporator

In the air conditioner, according to the type of condensation, it can be divided into two types: water-cooled and air-cooled. According to the purpose of use, it can be divided into two types: single-cooling and cooling and heating. No matter which type of composition, it is composed of The following main components are combined.

The necessity of the condenser is based on the second law of thermodynamics—according to the second law of thermodynamics, the spontaneous flow direction of heat energy inside a closed system is unidirectional, that is, it can only flow from high heat to low heat. In the microscopic world, it appears as microscopic particles that carry thermal energy. From order to disorder. Therefore, while a heat engine has energy input to perform work, it must also have energy release downstream, so that there will be a thermal energy gap between upstream and downstream, the flow of thermal energy will become possible, and the cycle will continue.

Therefore, if you want the load to perform work again, you must first release the heat energy that is not completely released. At this time, you need to use a condenser. If the surrounding heat energy is higher than the temperature in the condenser, in order to cool the condenser, you must do work artificially (usually using a compressor). The condensed fluid returns to a state of high order and low heat energy and can perform work again.

The choice of condenser includes the choice of form and model, and determines the flow and resistance of cooling water or air flowing through the condenser. The choice of condenser type should consider the local water source, water temperature, climatic conditions, as well as the total cooling capacity of the refrigeration system and the layout requirements of the refrigeration machine room. On the premise of determining the condenser type, the heat transfer area of ​​the condenser is calculated according to the condensing load and the heat load per unit area of ​​the condenser, so as to select the specific condenser model.
