Condenser side plate-L/R
Condenser (Condenser), a component of the refrigeration system, is a type of heat exchange that can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast manner. The working process of the condenser is an exothermic process, so the temperature of the condenser is relatively high.
Power plants use many condensers to condense the exhaust steam from the turbines. Condensers are used in refrigeration plants to condense refrigerant vapors such as ammonia and freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor into liquid state is also called condenser. All condensers operate by removing heat from a gas or vapor.

In the refrigeration system, the evaporator, condenser, compressor and throttling valve are the four essential parts in the refrigeration system, among which the evaporator is the equipment that transports the cooling capacity. The refrigerant absorbs the heat of the object to be cooled to achieve refrigeration. The compressor is the heart, which plays the role of inhaling, compressing, and transporting refrigerant vapor. The condenser is a device that releases heat, and transfers the heat absorbed in the evaporator together with the heat transformed by the work of the compressor to the cooling medium. The throttle valve plays the role of throttling and reducing the pressure of the refrigerant, and at the same time controls and adjusts the amount of refrigerant liquid flowing into the evaporator, and divides the system into two parts: the high-pressure side and the low-pressure side. In the actual refrigeration system, in addition to the above four major components, there are often some auxiliary equipment, such as solenoid valves, distributors, dryers, heat collectors, fusible plugs, pressure controllers and other components, which are to improve the operation Designed for economy, reliability and safety.
Air conditioners can be divided into water-cooled type and air-cooled type according to the condensing form, and can be divided into two types: single-cooled type and cooling and heating type according to the purpose of use. No matter which type is composed, it is composed of the following main components made.
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 in a closed system is unidirectional, that is, it can only flow from high heat to low heat, and in the microscopic world, the microscopic particles that carry heat energy can only From order to disorder. Therefore, when a heat engine has energy input to do work, energy must also be released downstream, so that there will be a thermal energy gap between the upstream and downstream, the flow of thermal energy will become possible, and the cycle will continue.
Therefore, if you want the load to do work again, you must first release the heat energy that has not been completely released. At this time, you need to use a condenser. If the surrounding thermal energy is higher than the temperature in the condenser, in order to cool the condenser, work must be done artificially (usually using a compressor). The condensed fluid returns to a state of high order and low thermal energy, and can do 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 room. On the premise of determining the type of condenser, the heat transfer area of the condenser is calculated according to the condensation load and the heat load per unit area of the condenser, so as to select the specific condenser model.
