INDUSTRIAL WATER COOLED-AIR CONDITIONER

The CorTec air conditioning system has a built-in heat-absorbing medium - refrigerant. The refrigerant generates pressure through the operation of the compressor. It is throttled by the expansion valve and passes through the evaporator inside the unit. The indoor fan blows the air indoors and absorbs the indoor air. The heat in the air and the refrigerant return to the suction end of the compressor through the pipeline. Through the compression of the compressor, the temperature of the refrigerant is increased. After passing through the wet curtain radiator of the outdoor unit, the refrigerant is converted from a vaporized state to a liquefied state. During the conversion process, a large amount of heat is released, and the heat is removed through the outdoor unit fan. Through repeated cycles, the purpose of rapid cooling is achieved, thereby quickly cooling the indoor environment. Water-cooled condensation reduces the evaporation pressure of the system and the exhaust pressure of the compressor, allowing the compressor to achieve a higher energy efficiency ratio and minimizing the input power of the compressor.

The water-cooled condensing temperature of traditional air conditioners is 56°C. In the harshest environments, evaporative air-conditioning units can also reduce the water-cooled condensing temperature to below 35 degrees. In the process of the heat exchange system, cooling is directly obtained close to the wet curtain temperature. water temperature, improve the energy efficiency ratio of the air conditioner, achieve energy saving effect, and the unit has no heat source to discharge, and will not cause pollution to the environment. After years of research and testing, CorTec's energy-saving air conditioners adopt Swedish CEID evaporative cooling technology, combined with many of CorTec's own technology patents, and multiple technical supports to accelerate the heat dissipation system of energy-saving air conditioners. Cooling, the energy efficiency COP during refrigeration is as high as 5.1, and the overall energy consumption is saved by 40%-50%.

Installation of industrial evaporative air conditioners:

1. Sufficient space, especially outside the access door and on the side of the external pipe, should be left around the industrial air conditioner to facilitate equipment repair and maintenance.
2. Small-type industrial air conditioners can be installed by hanging. Large-type industrial air conditioners can be placed directly on a cement base with a height of 150-200 mm, supported by 2 cm-thick shock-absorbing rubber underneath. The unit is fixed with expansion bolts, or it can be made of 14# channel steel base; the length of the channel steel base is equal to the total section length of the machine base, and the user prepares the channel steel bracket.
3. The water lines of the external pipes must be cleaned before they can be connected to the inlet and outlet pipes of the air conditioning unit. After passing the pressure test, wrap it with insulation material. Cold (hot) water is used as the medium heat exchanger, and the lower part is the water outlet. The water pipe at the bottom of the box is the condensed water discharge pipe. The condensed water discharge should have an appropriate slope and a water seal elbow. The water seal height should be ≥100mm to ensure smooth drainage.
4. The power supply of industrial air conditioners is 380V/3PH/50Hz AC, which must be reliably grounded. Check that the power supply voltage meets the requirements before connecting to the motor. Then start the motor and check whether the fan direction is correct. If the direction is opposite, stop the machine and connect the power supply. After the sequence is aligned, the power cord is formally connected.
5. The power supply of industrial air conditioners should be equipped with a starter and overload protection device corresponding to the unit. Motors below 11 kW can be started directly, and motors above 11 kW should be equipped with a step-down starting device.

Use of industrial evaporative air conditioners:

1. Industrial air conditioners should have professionals who are responsible for full-time management and operation. During operation, the operating status of the air conditioner should be checked frequently and regularly. Once any abnormality is discovered, troubleshooting must be carried out in a timely manner. It must not be started until the fault is eliminated. Forced operation will definitely cause damage to the air conditioner.
2. Cold (hot) coal is clean softened water, and the working pressure of the heat exchanger should not exceed 1.6MPa.
3. When the fan is operating normally, the bearing temperature does not exceed 40 degrees, and the air inlet temperature does not exceed 80 degrees.
4. When industrial air conditioners are running in winter, if a short-term shutdown is required, the exchanged hot water should be kept flowing continuously, and the fresh air valve should be closed to prevent the heat exchanger from freezing. If it is shut down for a long time, all the water in the heat exchanger should be drained.

Maintenance of industrial air conditioners:

1. After the industrial air conditioner has been running for one month, check whether the circulating water system and bolts are loose. If there is any looseness, the motor and wind wheel bearing fixing bolts can be readjusted and tightened to ensure that the equipment reaches optimal working condition.
2. The air filter should be cleaned regularly, depending on the environment. Cleaning method: Take out the filter, beat it and back-flush with compressed air, then clean it with soapy water, rinse it with clean water, air-dry it, and then reuse it. The college filter must be replaced when it reaches the final resistance.
3. Industrial air conditioners should be fully maintained after one to two years of operation (depending on the installation site). Use chemical methods to remove scale in the water pipes of the heat exchanger. Flush the heat exchange fins with compressed air or water.
4. For routine maintenance, the bearings should be injected with an appropriate amount of grease every quarter.
5. The motor and wind wheel bearings must be cleaned every year and replaced if necessary.
6. Regularly remove dust, dirt, water, and other debris inside the fan and gas delivery pipes to prevent corrosion.
