I've been working hard for a lot of chongqing zhongqing
There are five types of substances in the refrigeration system cycle, i. E. Refrigerants, oil, water, air and other impurities, which are necessary to ensure the proper functioning of the system, while the latter three substances are harmful to the system, but cannot. At the same time, the refrigerant itself has three states of gas phase, liquid phase, and vapour mixture. As a result, the reasons for the breakdown of the thongqing central air conditioning refrigeration system in the bhongqing region are complex. Below are a list of 11 common malfunctions of the tianchang central air conditioning refrigeration system in chongqing-banan。
One, the wind
There are two reasons for the non-rotation of the wind engine: electrical failure to control the circuit; and mechanical failure of the wind axis。
When the chongqing chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong cong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong chong cian chong chong cong chong chong chong chong chong chong chong chong chong chong chong cing cong chong cong cong cong chong cong cong cong cong cong cing cong cong cong cong cing cong cong cong cong cong cong cing cong cong cing cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cong cing cing cing cing cing cing cing cing cing when the chongqing central air-conditioning winder is not turned, the heat exchange efficiency in the chongqing central air-conditioning room in the chongqing south sector is reduced, and the temperature in the chongqing central air-conditioning room in the chongqing south region increases when the heat load in the chongqing south region is constant。
Refrigerants in the heat exchange tube may have lower temperatures relative to the original temperature, i. E. Lower evaporation temperatures and lower cooling factors for the system due to inadequate heat exchange. The temperature of the evaporation unit from which the thermostat expands is felt has also decreased, resulting in lower heat-inflation valve openings and a corresponding reduction in refrigerants, so that the exhaust pressure is reduced. The overall effect of the reduction in refrigerant flows and the reduction in the cooling factor was to reduce the system's refrigeration volume。
2. Low temperature of cooling water imports
As cooling water temperatures decrease, the exhaust pressure of compressors, vent temperature and filter export temperature are reduced. In chongqing, the temperature of the tianchang central air-conditioning room remained unchanged, as the cooling water temperature had not yet decreased to a level that would affect the cooling effect. If cooling water is reduced to a certain degree, the condensation pressure is reduced, resulting in lower pressure differentials on both sides of the heat-inflating valve, reduced flow capacity of the heat-inflating valve and reduced refrigerants, and thus less refrigeration。
3. Excessive cooling water import temperature
High cooling water import temperatures reduce the refrigeration capacity of systems by reducing the refrigerant overcooling, condensing temperatures, condensing pressures, compressor pressure increases, axle power increases and gas transmission coefficients decrease. So the overall cooling effect will be reduced, and the temperature of the tianchang air-conditioning room in chongqing-banan district will rise。
4. Circulation pumps
When debugging and operating, chillers should first open a system cycle pump. When the revolving pumps do not turn, the cooling water export temperature and the cooling-condenser refrigerant export temperature are noticeably rising, the compressor's air-inhaling and exhaust temperatures are rising rapidly due to a sharp drop in condenser's cooling effects, and the evaporation temperature is rising due to an increase in condensation temperature, but the increase in evaporation temperature is not significant because of a large increase in condensation temperature, so the cooling efficiency is reduced and the temperature of the chongqing south zone is rising rapidly。
Five, filter jam
A filter jam is a system blackout. As a general rule, smudges often occur in filters, because filter filters block the passages, filter out impurities such as dirt and metal crumbs, and are blocked by longer periods of cooling and central air conditioning in chongqingbana。
The effect of filter congestion is a reduction in refrigerant circulation, many of which are similar to the low rate of expansion valves being used, such as the rise in compressor exhaust temperature, the decrease in compressor exhaust pressure, and the recovery of the temperature of the sky plus central air-conditioning room in chongqing-banan region, unlike the lower temperature of filter exports. This is due to a reduction in the local temperature of the system due to the start of the run-off at the filter and the emergence of system local frosts or ice in serious cases。
6-chongqing, tianchang central air conditioning room is overloaded
As a result of the internal and external disturbance of the room and the effects of various factors, the workload of the thongqing central air-conditioning room in chongqing south region overloaded the temperature of the thongqing central air-conditioning room in chongqing south region, which fell short of the temperature target that should be maintained in the normal thongqing central air-conditioning room in chongqing south region. At the same time, the two parameters that have been significantly affected are compressor inhaler and exhaust temperature。
The impact of the hot air-conditioning room heat in tianchang, chongqing-banan district, will be evident only after a certain period of time。
Seven, the cooling flow is too small
Owing to the relationship between cooling water pipes and cooling water valves, as well as the small configuration of cooling towers in the system or the amount of mud in the cooling tower, too small a flow of cooling water and too high a temperature of cooling water imports are also common failures。
When cooling water flows over hours, thermal exchange effects of condensers are reduced, resulting in an increase in the temperature of refrigerants exported by condensers, an increase in the condensation temperature of refrigerants, and a reduction in the cooling factor, which affects refrigeration effects。
With other conditions remaining unchanged, the temperature of the tianchong central air-conditioning room in chongqingwan district will increase to a certain extent, as will the inhaling temperature of compressors. However, it is clear that the temperature differential in cooling water exports will increase。
8 - the swelling valve is running small
When the expansion valves are running small in terms of a normal refrigerant charge in the refrigeration system, the expansion valves are running through a small failure, the entire system cycle refrigerants are inadequate, and when other conditions remain unchanged, the liquid-state formulations cannot be fully satisfied with low-pressure gas inhaled heat, resulting in a high rate of return overheating, a rise in excretion temperatures and the temperature of the t-plus central air-conditioning room in the southern region of chongqing。
The temperature of the refrigerant exported by condensers decreases (i. E., increases in the system's cooling capacity), as the heat-replacement capacity of the condensers remains unchanged, but there is a very small flow of recycled refrigerants throughout the system, although at this time the cooling factor increased and the amount per unit of refrigeration increased. However, overall cooling has decreased, so the temperature of the tianchang air-conditioning room in chongqing-banan district will rise。
There's a small mouth inside the swelling valve (the yellow arrow place), which regulates the opening of the swelling valve, which regulates the size of the small mouth. The greater the opening, the greater the calibre, the more liquids flow。
9. Refrigerant deficiency
The shortage of refrigerants is usually due to inadequate pre-plant charge levels, which generally occur less frequently, and to the fact that the fleet operates on a perennial basis, which is a relatively common malfunction due to the fact that the system valves or welding parts are leaking too little. There is no clear difference between the reason for the failure of the refrigerant and the small expansion valve。
10. Excess refrigerants
The excess of refrigerants is due to blind refrigerant recharge, which is not uncommon when refrigeration systems are maintained. This reduces the effective heat-replacement area within the condenser and reduces the heat-replacement effect, resulting in higher condensation temperatures, higher condensation pressure and excessive pressure。
Too many refrigerants enter the evaporation unit without full gasification, and the compressor is inhaled to low pressure, the compressor's cask is condensed or frost, and in serious cases there is a fluid-shocking incident. Some liquid refrigerants enter compressors, increase electrical loads, have difficulties of start-up, operate in excess of currents and, in serious cases, burn down because of overloading。
