Observe the operation of the electrical system of the evaporator cooler fan

The electrical system of the evaporator cooler is a very important part. In the course of its use, it is necessary to maintain the operation of the electrical system by using the evaporator cooler.
1, check the evaporative cooler fan fan remote control point box components are normal.
2, continuous open and shut down operation, check the remote control is correct and reliable.
3, evaporative cooler fan fan test run two hours, observe the motor bearing temperature, motor temperature rise is within the normal range.
4, the control valve mechanical opening and closing action is flexible, reliable, open and close angle mark is clearly visible.
5, the indicator light and the voltmeter, ammeter are normal, evaporative cooler fan parts of the operation of all different sound, three-phase current value is balanced.
Regularly observing the use of the electrical system of the evaporator cooler fan can effectively improve the safety of the equipment and reduce the occurrence of the evaporator cooler fan failure.

Industrial wall fan of the purchase points

A fan of the use of electric motors to rotate the blades, thus accelerating the flow of indoor air, has reached the purpose of cooling. What are the points that we have to pay when we buy a wall fan? The following to introduce the following:
1. Look at the net and the leaf
The appearance of the industrial wall fan is intact, check whether the mesh cover and the blade are deformed. In the assembly of a good wall fan cover, with a pen pointing to the highest point of a fan, slowly move the fan, the other few leaves corresponding to the distance between the tip and the tip should be very similar, and then check the fan's rotation flexible.
2. See start performance
Start performance is an important indicator of the quality of industrial wall fans. In the purchase, the wall should be adjusted in the slow speed, and the power supply rated voltage of 85%, that is, with a voltage regulator to 220 volts to 187 volts when starting the industrial wall fan, should be able to start from the static, Can maintain normal operation, if the shorter the start time, indicating the better performance of industrial wall fan start. The shorter the time required for an industrial wall fan to start from normal operation, the better the starting performance of the fan motor.
3. Look at the operation and speed performance
Power on the shaking his head after the switch several times, check whether the failure or assembly too tight, in this process, the fan mechanical transmission part should not have abnormal noise. Wall fan in the high, medium and low speed operation, the motor and fan should be smooth, small vibration, low noise. Wall fan shaking his head, shut down should be agile, no intermittent, stagnation and jitter phenomenon, the block speed difference should be obvious, the air angle the bigger the better. When the fan stops, the shaft axial clearance does not exceed 0.5 cm, the gap is too large, the operation will cause axial movement and impact sound.

The environmental requirements of the fan

1. On the water curtain fan planning and installation staff can not be treated, if the indoor windows from the ground is very high, then the wet curtain interval will use the negative pressure vertical ventilation method of the best interval, fan and wet curtain device at both ends The

2. When the end of the room has a working hour, the wet curtain can not be installed on one end of the wall, then the wet curtain device can be in the room close to the side wall, the fan is installed in the opposite wall, Angle device.

3. When the workshop in the gable interval is too long, the fan ventilation interval of less than the expected role, in order to reduce the loss of resistance to the choice of horizontal ventilation method, that is, fan and wet curtain group of devices.

4. The placement of the wet curtain is usually selected in the upper air outlet, the fan placement of the air outlet, wet curtain inlet must be left to meet the intake space.

5. Usually a fan equipped with 6-8 square curtain is appropriate, and to spread evenly.
 
6. Negative pressure fan and wet curtain use of embedded devices, is set aside in the walls of the premises or is now chisel fan and wet curtain position.

Can water be recycled?

This problem is the problem of water cycle, is fully recyclable and re-use. Is also the entire system of the arteries. The water circulation system has a reservoir, water pump and water distribution network composed of the entire water cycle system is: water pump out through The inlet pipe enters, flows from the outlet and returns to the reservoir, and the advantage of using the water circulation system is to save water. The water in the reservoir will evaporate with the process of cooling less and less, so often observe the reservoir water level is too low when the timely water, water selection is also very important although the spring, well water, rivers and lakes in the water Can be used, but must be no pollution of water quality, water PH value is generally between 6-9, PH value is too high or too low water are not used, and with brick and other heavy pressure solid, commonly used water pump There are: submersible pumps, centrifugal pumps, deep well pumps, pipeline pumps and so on. The role of the pump is to pressurize the water pressure to the system, and send it to the water pipe network.

With ventilation equipment, to achieve healthy breathing in the room

How to use the ventilation equipment to achieve the room Ankang suction, professional window to do the natural ventilator manufacturers foot art is so with our island Mei.
Purification is "hold back" out, more than 50% of the respondents every evening window ventilation time less than 15 minutes. Plant cooling Although the majority of residents are self-sacrifice to read the indoor atmosphere of the amount of hint that there is no water level is not modest, but the ventilation of the tail, as is still important to pay attention to the team is especially in the summer by the temporary closed Indoor, will lead to awe-inspiring atmosphere, the impact of the occupants of the suction so that the local body well-being, control shop ventilation black and white often tail to.
It is "there is not any approval, and there is no one in the morning, and there is a lot of fine particles in the atmosphere of the" But not according to the data looming, shallow state room in addition to the night gas of the rebellion of the amount of 400 to 500 / m3, and dilute the room in the back of the amount of guards as long as 40 to 50 / m3 , As long as the camp when the camp hours, window frequency, war and window when the sugar, is the right time to stop the public care and wisdom, it is possible to introduce the new atmosphere of the room indoors.
Experts in the summer, is not too much inside the night in the environment, you can open a hurry every day hurry to find, bid farewell to the morning 9 to 10 face war 2 to 3 (escape the evening and evening purification Section), each time in addition to the night about half an hour to an hour.
So that the indoor atmosphere is often new, is the ancient winter of each room to contain the "closed task." Cooling fan
Indoor ventilation is like a dead island to be a hot topic, but with the country close the policy suck, how well ventilated ventilation is being closed in the long term. The people who are still in the air-conditioned environment may often feel infected with chest tightness, shortness of breath, and is also for the central air-conditioned room will feel a lot of pleasure, it is because the Department of the city between the air conditioning with "ventilation" Demolition, a round of indoor muddy atmosphere "suck out" room, the other will be a new atmosphere in the "suction" into the room, "a suction wild Pu" between the arrival of the forest ventilation ventilation impulse, Ventilation equipment Its natural soundproof ventilator can achieve this policy.

Natural ventilator operation to do the atmosphere inside the pressure pressure (warm and war the lower level of wind pressure, etc.), so that the atmosphere of the indoor war room to curb the natural fluency, or by means of power ventilator (with motor) will be indoor atmosphere of the introduction of indoors, Positive pressure, and then through the process of natural ventilator will be turbid atmosphere in the empty room. The natural ventilator is ventilating at the same time can stop the rain and snow, evaporative cooler pads noise, sand, insects and other objects into the room, even in the sleeping environment, just turn the back of the atmosphere of the movement of the United States did not make the body feel The

The advantages and disadvantages of evaporative air cooler

Energy-saving environmental protection air-conditioning (also known as water evaporative air cooler, chillers, air conditioners, water-cooled air-conditioning) is a set of cooling, ventilation, dust, in addition to taste in a evaporative cooling unit. It is to rely on evaporation to absorb the heat in the air to achieve the purpose of cooling, according to the natural physical phenomenon "water evaporation efficiency" principle: when the hot air through the actual heat transfer area of ​​100 times the water evaporation of the air cooler pads, its large amount of heat Absorbed by the air, so as to achieve the process of air cooling.

In addition to environmental protection air conditioning can be to the business workshop, public places, commercial entertainment occasions to bring fresh air and reduce the temperature, the important feature is energy saving, environmental protection. It is a non-compressor, no refrigerant, no copper tube of the new environmentally friendly products, the main components of the core one by one evaporative wet curtain (multi-layer corrugated fiber stack) and 1.1KW main motor, the run-time consumption Electricity is only the traditional central air conditioning power consumption of 1/8.

Energy saving and environmental protection how air conditioning - energy saving and environmental protection advantages and disadvantages of air conditioning

1, less investment, large efficiency.
2, less power consumption, electricity consumption per hour only 1 degree.
3, every hour to send cold air volume of 18,000 cubic meters, wind pressure, air supply far.
4, automatic electronic control and automatic cleaning function.
5, the use of three impeller airfoil before the swept leaves, low noise, high efficiency.
6, the use of 100mm thick multi-layer wave fabric texture wet curtain, cooling capacity particularly strong.
7, ventilation, ventilation, dust, in addition to taste, cooling set in one.
8, increase the air oxygen content, improve work efficiency.
9, natural air supply or post air supply free choice, DC and frequency free choice.
10, adjust the humidity: some need to increase the humidity of the workplace for humidity adjustment.

Energy saving and environmental protection in the refrigeration efficiency and energy consumption is very advantageous, in other areas, environmental protection and energy saving air conditioning there are some deficiencies: such as in a large area of ​​refrigeration heating effect, industrial evaporative air cooler less than the traditional air conditioning, the temperature can only be adjusted at 30 ° ; And now China's energy-saving environmental protection air-conditioning has not yet clear policy, combined with environmental protection and energy saving high cost of air conditioning, leading to ordinary consumers is difficult to accept.

Working principle of chillers

Cooling fan, also known as environmentally friendly air conditioning, water and air conditioning, as the name suggests the main cooling medium cooling water, but how to use water heat to make the indoor cool, cold fan works?
First of all, we need to understand the structure of the chiller and the role of each structure:

The following figure is the profile of Changrun electromechanical cooling fan
We can clearly see the main structure of the cooler: 1) wet evaporative cooler pad; 2) axial fan; 3) fan motor; 4) water ball valve ;; 5) electrical box; 6) circulating pump.

These parts make up the chiller, but also a few parts that allow ordinary water cooling effect, then the role of these accessories is what? We come to one by one to understand.

Wet evaporative cooler pad: it is the carrier of water, water in the wet evaporative cooler pad to get a good evaporation, the heat of the hot air all absorbed, making the indoor air temperature dropped to achieve the purpose of cooling; but because wet evaporative cooler pads long contact with water, Need regular maintenance, to prevent the wet evaporative cooler pad is blocked by stolen goods, affecting the cooling effect. (Changrun environmental air conditioning using Jiamusi paper and Sweden Wellhead PP glue, no smell, while environmental protection will set the function of air cleaning, plus the use of air filters, making the wet evaporative cooler pad life more long).

Axial fan blades: fan rotation to drive the entire air supply system, the outside world, fresh and cool breeze into the room. Feng Ye long-term high-speed operation, so Changrun electromechanical selected wind-toughness toughness, thick blade, to ensure the normal use of water-cooled machine.

Lengfeng Ji motor: the motor has been called the motor, is the core of Lengfeng Ji accessories, and its role is to promote the rotation of the fan. Electrical and mechanical also often continue in the high frequency of work, if the quality, but off, easy to burn the motor, thus affecting the use of cooler. (Changrun chiller is a copper motor, a change of copper clad aluminum motor, although the appearance is not much change, but we guarantee that the customer is "real material."

Water ball valve: water ball valve has a float, it is the water into the machine switch and barrier, the role of float is to control the water, if the quality of the float, however, the chiller is easy to leak;

Electrical box: the chiller controller, we also call the control panel, which controls the entire machine, the amount of wind, automatic cleaning time, boot, shutdown, etc.;

Circulating water pump: And the role of the human body is similar to the heart, the water distribution to the manifold on the uniform stay in the wet evaporative cooler pad, and then concentrated in this delivery of the water separator, the reciprocating cycle;

Understand the basic role of accessories, we have a working principle of chillers have a rough idea, then we have to be a specific description:

This diagram illustrates the working principle of the chillers
Water through the water into the ball valve into the environmental air conditioning, and then by the circulating pump and water pipes to the water diversion plate of the chiller, the water evenly walk in the wet evaporative cooler pad, so hot air comes in, will first evaporate through the wet evaporative cooler pad evaporator, Taste, dust. After the treatment of the air will be sent, such as indoor fan rotation, making the indoor cooling, ventilation, chillers works like that simple!
