When there is a high pressure alarm in the water-cooled chiller, it is mainly related to the cooling water system:   1. Cooling water valve is not opened   The water cooling unit is provided with circulating cooling water by the cooling tower. If you forget to open the cooling water valve during use, the cooling water will not be circulated to the chiller.   Solution: Open the cooling water valve.   2, cooling water flow is too small or cooling water temperature is too high   These two conditions will lead to poor heat dissipation, the refrigerant temperature can not be cooled, there will be high pressure alarm.   Solution: Check whether the installed pipe size matches the size of the chiller, whether the pump works normally, and whether the water valve is opened to the maximum position.   3, cooling water tower failure   When the cooling tower fails and the cooling water cannot be circulated to the chiller, a high pressure alarm will occur.   Solution: Check whether the cooling tower is faulty.   4. Scale   If the water-cooled chiller is used for a long time without maintenance, it is easy to lead to the accumulation of debris such as scale on the pipe wall, which is bound to affect the efficiency of the condenser.   Solution: Clean up the scale.

In hot summer, many air-cooled chillers have high pressure alarm,especially in areas with relatively high temperatures which can be above 45℃, such as Saudi Arabia, the United Arab Emirates, Iraq and so on.   General air-cooled chiller is equipped with a full set of protection devices, when the chiller appears high pressure alarm, it will automatically start the protection device, and the corresponding fault indicator light will be lit.   The high pressure alarm of the air-cooled chiller is triggered by the poor cooling effect of the condenser.If this problem is not fixed and keep running the chiller at high pressure for a long time, it will cause the current to be too large and burn the compressor.   The reasons for the chiller high pressure alarm are as follows:   1. Air-cooled chiller’s condenser rely on fans to dissipate heat.When the ambient temperature is above 42 degrees, the heat dissipation of the condenser is poor, that is, the heat generated by the refrigerant circulation cannot be taken away by the fan.   2. The condenser is dirty and blocked, which will also cause poor heat dissipation and lead to high pressure alarm.   Solution: 1. Check whether the fan works properly. 2. Make sure there’s good ventilation to exhaust hot air smoothly. 3. If the ambient temperature is higher than 42 degrees, use a fan or cooler to cool down the temperature around. 4. Periodically remove the air filter to clean the fins or clean the fins with high-pressure air. 5. If the ambient temperature is around 42 ℃, need to increase the condenser size to improve heat dissipation efficiency.Normally, we will increase size to 25% for chiller using refrigerant R22, R407c, R410a. If ambient temperature higher than 45 ℃, we suggest to design the chiller with R134a which can be used at ambient temperature of 50 ℃.The disadvantage is that the cost is relatively high, because its refrigeration efficiency is only 65% compare with other refrigerants, in order to achieve the same cooling capacity, you must use a larger compressor.   P.S. The installation of air-cooled chiller should choose the right location to ensure that the installation environment is well ventilated.

  In the summer, many factories need to run the chiller for24 hours everyday, which is very high efficiency.But in winter,many factories insome areasdon’t need chillers to cool. When shuts down the chiller, we must do a good job in the maintenance of chiller, so how to maintain chiller in winter? Ⅰ Clean 1. Shut off the water source of the chiller, and clean the water inside the unit components and pipes to avoid water corrosion of the unit components after the shutdown or frost-swell copper pipe with too low temperature. At the same time, the drain nut under the water pump should be unscrewed to drain out the remaining water in the water pump, so as to prevent the water system from freezing due to the low ambient temperature,and lead tothe evaporator bursting and cracking which may cause the refrigerant leakage or damage of the pump impeller and other faults. 2.Clean the fans of the air-cooled chiller and keep it in a clean. 3.Whether tank of evaporator is anyimpurity, and remove it. 4.Check the using of lubricating oil through data records, and replacing the lubricating oil regularly according to the standards to maintain a good lubrication. 5.Cooling water pipes of the chiller must be insulated which not only prevent the serious loss of cooling capacity, but also prevent the dew formed on the outer of the pipes. Ⅱ Maintenance 1.Keep refrigerant and oil in clean and moisture-free to avoid moisture pollution.Need vacuum to remove moisture after maintenance on any part of the cooling system and before restarting work. 2.Keepclean for the in letfilter of the chiller. Regular inspections are required, especially forthe suction passage of compressor there may be welding slag and pipesrust.There are too much dirt on the suction filter, which will cause to fracture filter, and particles leak into compressor. 3.Keep clean forthe oil filter. If there is an increase in pressure-drop , it indicates that there is dirt, and it is necessary to shut down thechiller to clean or replace theoilfilter.Compressor runs under high pressure-drop for a long-term, which will cause to run out ofcompressor oilanddamage bearings early. 4.Avoid the chiller compressor from being blocked by liquid refrigerant. Make sure that there is overheating enough and the suitable suction accumulator to avoidcharge liquid refrigerant into the compressor. Liquid refrigerant will cause tocut the lifespan of the compressor, and complete damage to the compressor under extreme conditions. 5.Protect the compressor during shutdown forlong-term.If non-operational shutdown for a long term,and then the compressor should be vacuumed to low pressure and then filled with nitrogen or oil. 6.As long as the compressor shows obvious change in vibration level, noise, or performance in any time, it should be taking preventive maintenance inspections.

  1.Cooling system leak There are leaks in the connecting pipes of the cooling system,such as welding point leakage, corrosion leakage, fracture caused by mechanical vibration,and human factors, etc. These will leads to malfunction of low pressure. Solution First of all, use leakage detection liquid (soap water, or detergent mixed with water) or halogen leak detector to find the leakage point. After the leakage point is found, repair it with welding equipment,then pressure holding to test leak and vacuum pumping before charging refrigerant according to the manufacturer's specifications, the chiller can resume normal operation. 2.Cooling system blockage A. Blockage By impurities If the filter is blocked due to dirt, it will only cause the cooling capacity drop slightly, and you may not even feel any affected.When the filter is slightly clogged, there will be a temperature difference of the inlet and outlet of the filter, which can be felt by holding the inlet and outlet with your hand.When it is block seriously, the filter will dew or frost. If there is dew or frost (except the dew after the chiller stop running under normal operation), it can be judged that the filter is block. Solution Replace the filter of same model B.Ice Blockage The water in the system runs with the refrigerant to the throttle valve (expansion valve). After throttling expansion, freeze at throttle outlet, thus blocking the throttle valve (expansion valve) and lead to a low-pressure fault. Solution Change the filter with same model. C.Expansion Valve Damaged Expansion valve is affected by environment in the process of using. There is corrosive gases that will corrode the liquid in some environments,which will corrode the expansion valve. Solution Replace new expansion valve of same model 3. Heating exchange of evaporator is seriously in sufficient. A.Insufficient water flow in the evaporator The water pump is broken or something bad enter in to the pump impellers,appear leakage in the water inlet pipes of water pump,(It is difficult to check, needs careful analysis),which are resulting in insufficient water flow. Solution Replace water pump. Or disassemble the water pump to clear the bad something in the impellers. B.Evaporator is blocked by bad something Firstly, you must eliminate the problem of the water pump. When the equipment is normal, there will not be a lot of condensed water,frostorice on the surface of the compressor. When you see a lot of condensed water,frostorice on the surface of the compressor, it can basically be judged that the evaporator is blocked. Solution If the evaporator is blocked or the evaporator tubesarescaled,please disassemble the evaporator,and remove the evaporator tubes, then rinse with a high-pressure water gun or soake and wash with a special chemical liquid.
