In a seemingly simple refrigeration system, many components are often required to cooperate with each other to complete the whole refrigeration process. Evaporator, condenser, compressor and throttle valve are the four essential parts of the refrigeration system. Today we are going to learn an important part of the refrigeration system—Condenser.
What is condenser?
Condenser is a type of equipment that is capable of condensing substances from gas state to liquid state. It is also a heat exchanger, condensing matters by the way of cooling. When condensed, the matter will radiate latent heat and some sensible heat, thus increasing the temperature of cold medium in condenser.
The functions of condenser
Condenser is a crucial part for the cooling process. In the whole condensing system, refrigerant in the condenser tube directly and forcibly exchange heat with the outside air to achieve the cooling effect. Therefore, condenser stays in the state of radiating heat during its working and the temperature of the condenser becomes relatively high. In order to make condenser dissipate heat in time to keep the whole refrigeration system in good operation, a fan with high performance is paramount.
Refrigeration Modes Of Condenser
01 Air Condenser
1.The air condenser condenses the high-temperature gas-state refrigerant, and at the same time the axial fan exhaust the hot air to the outside, thus achieving the cooling effect. The cooling process presents the advantages of high efficiency and saving energy.
2. Each air condenser comes with refrigeration system that can be operated independently.
3. Each air condenser owns a simple system structure which can be installed easily with little construction difficulty. The computer room space occupied by its ducts is small, and only the installation space is required.
4. Air condenser is usually applied to small and medium-sized computer room (＜1000KW, 1000m³) or some places without professional maintenance personnel. Air condenser is suitable for small and medium-sized refrigeration equipment or water-deficient area.
02 Water-cooling condenser
1. Water-cooling condenser has no refrigeration system.
2. The unit has the advantages of simple structure, less faults, less maintenance workload and low single machine cost.
3. It can achieve types of energy-saving operation including high water temperature and high return air temperature energy-saving operation mode, intelligent backup management energy-saving operation mode, elevated floor static pressure management energy-saving operation mode, etc, by the use of EC fan.
4. The system design is complex and sharing water supply pipelines may lead to system risks. When the load and equipment are put into operation by stages, the system reservation design needs to be done in advance, otherwise it is difficult to expand the capacity in the later stage Water-cooling condenser is suitable for large computer room.
03 Evaporative condenser
1. Evaporative condenser: this type of condenser works by the principle that using the cooling effect generated by the evaporation of the refrigerant in another refrigeration system to cool the refrigerant vapor on the other side of the heat transfer wall, so as to promote the latter to condense and liquefy.
2. It has the advantages of compact structure, small space, simple usage and maintenance, stable performance, water and electricity-saving ability and low operational pressure.
Condenser fan selection
For a variety of application environments of condenser, the condenser fans professionally supplied by Beijing Hengrui have passed the practical test. At present, they are widely used in various large-scale refrigeration equipment. With the excellent quality, high quality and long service life, ebmpapst fan can freely respond to various working conditions and environments, timely ventilate and dissipate heat for the refrigeration system, greatly increasing the service life of the equipment.
Ebmpapst condenser fan can realize regulation operation, ensuring that air performance can better adapt to changing refrigeration requirements, power input can orderly decrease and energy demand can orderly increase. The aerodynamic performance can be optimized by continuously adjusting the speed. All fans can keep running, thus saving a lot of power input.
The centralized condensing unit solution can not only solve the problem of outdoor land occupation, but also solve the demand for energy saving and improve the reliability of the refrigeration system. It is modular, independent, easy to expand, easy to manage and easy to maintain.
Recommended Condenser Fan
The most common AC fan series for condenser:
Large fans with the diameter of 800mm and 900mm are especially suitable for refrigeration equipment including condenser, evaporator, etc.Its air volume is able to be up to 40,000 m³/h and its pressure range 350 Pa.
Fans of above dimensions can be replaced with EC fans with higher performance.
Application Advantages of Ebmpapst Fan in Condenser
EC fans can achieve stepless speed regulation, high efficiency and energy-saving
Plug and play, each component is coordinated
10% higher air performance, 3 dB(A) less noise
Suitable for being used outdoor for its stout and durable design
It can achieve higher efficiency and power density in the same installation space for its agile layout
Applications area
Though as a component of refrigeration system, condenser can be also used in public buildings such as offices, large malls, etc, refrigeration and air conditioning equipment including workshops, cold storage and heat exchange systems used by industries including food, pharmacy, petroleum, chemistry, etc.
(Application case of EC fan in Canton tower)
As well as condenser fan used in refrigeration system, Beijing Hengrui Hongsheng is also capable of supplies types of cooling and heating fans for cooling tower, evaporator, heat pump, oil cooling system, etc. Our professional model selection team is able to provide you with customized fans solutions, saving your time and energy!
