Air-cooled chiller | Air-cooled chiller | Air-cooled industrial chiller - East-leap chiller plant analysis Air-cooled chiller refrigeration system There are six major effects of air: Air-cooled chiller is a compressor, evaporator, condensation A cooling device with a sealed structure, such as a device, a throttling device, a water tank, a water pump, an electronic control system, etc., which mainly utilizes its own fan to dissipate heat, and does not require other auxiliary equipment, and in particular, the installation is the simplest, so it is widely favored by users. Currently, it is one of the hot-selling chillers of Dongyuejin Chiller Factory.
The cooling effect of an air-cooled chiller, in addition to looking at its main components, also ensures that the refrigeration system is in good condition. Even if there is a little air in the refrigeration system, it will affect the unit operation. The reason for the presence of air in the refrigeration system may be the lax vacuum of the refrigeration system; improper operation during charging of the refrigerant or refueling; operation of the low-pressure system under negative pressure; or improper operation and other reasons.
Since air is a non-condensable gas, when it enters the refrigeration system of an air-cooled chiller, it can cause the following six major effects:
1. The condensing pressure rises. After the air enters the condenser, it occupies a certain volume and has a certain partial pressure. As more air accumulates, the higher the partial pressure, the higher the pressure in the condenser.
2, reduce the condenser heat transfer efficiency. The air accumulates in a certain area in the condenser so that the inner surface of the area is surrounded by air, and the heat cannot be effectively dissipated, so that the condensing temperature is increased.
3, corrosion of pipelines and equipment. The entry of air causes the water content in the air-cooled chiller system to increase, causing corrosion of the pipeline.
4, cooling efficiency. As the condensing pressure increases, the compressor's gas delivery volume decreases, the motor's operating flow increases, the power consumption increases, and the cooling efficiency decreases.
5. The compressor discharge temperature increases. When the temperature approaches or exceeds the flash point of the lubricant, the lubricant can easily decompose and cause an accident.
6. When the moisture entering the system reaches a certain amount with the air, the “ice blocking†accident is easy to occur, making the refrigeration system cycle poorly or even interrupted.
Air into the refrigeration system, whether large refrigeration systems, or small refrigeration equipment, will have adverse consequences. If it is found that air enters the chiller refrigeration system, it should be repaired in time. In order to ensure that users can use chillers with good cooling effect, stable operation and durability, Dongyuejin Chiller Factory conducts 100% performance test before the unit leaves the factory, and it is filled with refrigerants and lubricants to ensure sufficient cooling capacity. The parameters meet the relevant standards.
