1*40HC shipping to Malaysia, Low temperature screw water chiller with water tower and other accessories. After discussed with our engineer and sales, we arranged the chiller to Malaysia fluently. By the way, there are some interesting stories during the order, Mr. Chen(client) ask for other accessories from us, like water tower, water cooling pump, SS tube, PE tube and Galvanized steel tube, we also help purchased for his convenience. In the end, his engineer Mr. Alex visit our factory for checking the chiller, very satisfy from our design, and factory power. If you have chiller request, just come to Kaydeli, we will give you a satisfied proposal, also we looking forward to long-term business relationship, win-win is our final goal. Kaydeli, give you infinite cool with insured service.

The industrial chiller consists of three interconnected systems: a refrigerant circulation system, a water circulation system, and an electrical control system. First, the refrigerant circulation system The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. The liquid refrigerant is completely evaporated into a gaseous state and then sucked in and compressed by the compressor. The gaseous refrigerant absorbs heat through the condenser, condenses into a liquid, and passes through a thermal expansion valve ( Or capillary) becomes a low-temperature low-pressure refrigerant after throttling into the evaporator to complete the refrigerant cycle. Refrigeration system Compressor: Compressor is the core component of the refrigeration system. It is used to convert the input electrical energy into mechanical energy and compress the refrigerant. Condenser: The condenser acts to output heat and condense the refrigerant during cooling. After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, the heat absorbed from the evaporator and the refrigeration compressor and in the pipeline is transferred to the surrounding medium (water or air); the refrigerant high-pressure superheated vapor Recondense into a liquid. Reservoir: The reservoir is installed after the condenser and is in direct communication with the drain of the condenser. The refrigerant liquid in the condenser should flow unimpeded into the reservoir so that the cooling area of the condenser can be fully utilized. On the other hand, when the heat load of the evaporator changes, the required amount of the refrigerant liquid also changes, and at that time, the reservoir functions to regulate and store the refrigerant. Drying filter: moisture and dirt (oil, iron filings, copper filings) must be prevented from entering the refrigeration cycle. If the moisture in the system is not removed, when the refrigerant passes through the throttle valve (thermal expansion valve or capillary) Due to the pressure and temperature drop, the water will solidify into ice, which will block the passage and affect the normal operation of the refrigeration unit. Thermal expansion valve: The thermal expansion valve is both a flow regulating valve and a throttle valve in the refrigeration system. It is installed between the drying filter and the evaporator in the refrigeration equipment, and its temperature sensing package is wrapped at the outlet of the evaporator. At the office. Its main function is to reduce the pressure of the high-pressure normal temperature refrigerant liquid when flowing through the thermal expansion valve, and become the low-temperature low-pressure refrigerant wet steam (enter the evaporator, vaporize and absorb heat in the evaporator, and achieve the purpose of cooling and cooling. Evaporator: An evaporator is a heat exchange device that relies on the evaporation of a refrigerant liquid to absorb the heat of the cooled medium. Its function in the refrigeration system is to absorb heat (or output cooling). In order to ensure a stable and long-lasting evaporation process, the vaporized gas must be continuously withdrawn by a refrigeration compressor to maintain a certain evaporation pressure. Refrigerant: Its role is to carry heat and achieve heat absorption and heat release when the state changes. Second, the water circulation system The water circulation system is a pump that draws water from the water tank to the equipment that the user needs to cool. The chilled water takes the heat away and the temperature rises, and then returns to the chilled water tank. Third, electrical control system The electrical control system includes a power supply section and an automatic control section. Power supply part: It supplies power to compressors, fans, pumps, etc. through contactors. Automatic control part: including thermostat, pressure protection, delay, relay, overload protection and other combinations to achieve automatic start and stop according to water temperature, protection and other functions.

Almost everyone is quite sensitive to noise. When there's a lot of noise, we tend to lose focus on everything we do, and our mood can be quite irritable. If the machine has noise, also need to find the fault point in time. If you let it make a lot of noise, it won't be long before the machine breaks down. What are the common causes of chiller noise? It may be that when the blades rotate, there will be friction or impact with the air, that is to say, the high-pitched resonance. It is suggested that the number of blades between the two fans should not be the same. During the operation of the fan, a vortex will be generated on the back of its power. This vortex will not only reduce the efficiency of the fan, but also generate noise. In order to alleviate this phenomenon, great care should be taken during installation that the blade mounting Angle should not be too large and the blade bending should be smooth. The noise of the chiller fan may also be caused by the resonance with the air duct shell. Duct and the fan shell side seams should level off, try to avoid rough, or it will send out the voice of tear, and at the time of design, can be attached on the outside of the air duct insulation material, it can effectively reduce the noise, in addition to these a few respects we mentioned just now, there are a lot of noise source, for example, bearing because not enough precision, inadequate or improper assembly maintenance can cause abnormal noise, some part of the motor will produce noise, some because of poor design, and some because of poor quality control.

If the water chiller is used for a long time, say months, even years. If the water quality in the area is the kind of water prone to scale, there will be a large amount of scale. These harmful substances gather on the inner wall of the condensing pipe. If the quality of these harmful substances is relatively high, the working efficiency of the cooling cycle system of the chiller will be greatly reduced, and the internal pressure of the chiller may be too high. Therefore, a better solution is to clean and maintain the chiller regularly. The cooling water system and condenser should be cleaned in time, and the filter should be changed frequently. If the internal pressure of the chiller is too high, it may also be the cooling water system that appears on the water-cooled chiller, or the cooling water valve is not opened, or the cooling is caused by other reasons, and it cannot smoothly supply circulating cooling water to the chiller, so the internal pressure is naturally high. The high pressure of chiller has great influence. If the chiller is well used, why does the pressure appear to be too high? Check to see if there is any blockage in the cooling system. The formation of fouling fault is probably due to excessive impurities in the refrigeration system. Also, check if the refrigerant is being overcharged. Refrigerant overloading is a serious problem, and excess refrigerant should be released as soon as possible.
