The application scope of air cooler is very wide, widely applicable to workshops, factories, Internet cafes and other places in all walks of life. Cooling fan running at work, outdoor hot air through the filter unit, and then after wet shelter, cooling and oxygen is high, the strong cold air flow through the duct to the workshop, workshop space pure and fresh, ventilation cooling, air in air pressure increases the size of the old workshop through the doors and Windows, discharge, outdoor air in the workshop has air conditioning, About 20 times per hour or more of the overall ventilation of the workshop heat, dust, odor discharge, make the workshop air quality fresh, comfortable and achieve cooling effect.

It is worth mentioning that the cooling effect of the air cooler is directly related to the air exchange rate, so is it right to say that the greater the air exchange rate, the better? Of course not.

Different places, the amount of air change will certainly be different. In general, the required number of air changes is about 25-35 times per hour. The general place referred to here is the place where the flow of people is not very large and there is no heating equipment, such as the conference room. At this time, if you enlarge the number of air changes, it is a bit of a waste of suspicion. For crowded places, the required number of air changes is about 30 to 40 times per hour. If it is a production workshop with heating equipment, then how also need to have 50-60 times/hour air change.

The energy-saving cold air machine mainly makes the air in the workshop timely update and conditioning to humidity, the improvement of air quality, and the human body can absorb fresh air in time. Thus determining human health.

1, tidy up the impurities of the protective net,

2. Check the softness of the belt. If it is found to be loose, adjust and reset it immediately.

3. Whether the bearing of the motor has abnormal sound, if there is, check whether there is lubricating oil on the motor!

About the maintenance and protection of the motor, we can start from the following aspects:

1, first disconnect the host power supply, check whether the ground is outstanding grounding;

2. Check whether the screws and couplings of each part are fastened.

3. Check whether the insulation resistance of the motor meets the requirements and check the main loop contact according to the instructions. Contact should be replaced immediately if it is severely ablated or severely worn.

The maintenance of the air valve can be considered from the following aspects:

1. Adjust the tightness of the belt, rotate the wind wheel by hand, and investigate whether the rotation is smooth. 2, view and replace the gasket and sealing filler between the joint surface.

3. Clean the inside of motor wind wheel, filter and casing. In order to avoid rust, part of paint should be timely brushed. 4. In order to ensure the sensitivity and stability of the coupling and bearing, lubricating oil should be added to the rotating part.

About the repair and maintenance of the electrical circuit, we should pay attention to the following points:

1, regulating valve mechanical open and close action is sensitive, reliable, open and close view point mark is clearly visible.

2, indicators and voltmeter, ammeter are normal. All parts of the fan work with abnormal sound, three-phase current value is balanced. 3. Check whether the components in the control box of each remote control point are normal.

4. Start and stop successively to check whether the remote control at each point is correct and reliable.

5. Test work for two hours, observe whether the motor bearing temperature and motor temperature rise are within the normal range.

With the improvement of the quality of life, air conditioning has become a necessity for home life, many occasions are inseparable from it. With the gradual strengthening of people's awareness of environmental protection, environmental protection air conditioning has become the new favorite of people gradually occupy the market. Today we talked about environmental protection air conditioning suddenly does not refrigerate.

Believes that many people would have such experience, after our environmental protection air conditioning with the gears or more short period of time, often will feel environmental air conditioner doesn't work, small wind, no refrigeration, sometimes outlet blow out a lot of water damage, accompanied by smell, display failure, drainage continuously, environmental protection air conditioning outdoor chassis leakage repeatedly repair and so on. All of which means your eco-friendly air conditioner needs cleaning.

Because environmental protection air conditioning operation will be outdoor dust and foreign bodies from the air, bacteria particles block, adsorption in the filter net, long running without cleaning screen will form the screen is completely closed, small wind, moisture evaporates slow, influence the refrigeration effect, feel there is no air conditioning, electrical work, outdoor air will not to the water on the evaporator inlet duct to blow into the interior, The wind nozzle blows water and the wind pipe leaks. Over time, the motor current load increases and the coil temperature rises, causing the motor to burn out and the panel display fault flicker, resulting in the inability of the environmental protection air conditioner to operate.
