Environmental protection air conditioning maintenance:

Pre-season maintenance: before the start of the use season, check whether there is obstruction around the unit and the air inlet.

Unit periodic maintenance: the unit runs for 1-2 months. If the wet curtain, dust filter is blocked or the chassis is too dirty, it should be cleaned on time to avoid machine failure.

Maintenance at the end of the season :(do not use it for a long time, remember to drain water and cut off the power! In order to prevent freezing damage to the body and mosquito breeding, when it is used for a long time, the tap water should be turned off, and then the water should be drained by pressing the cleaning button, and the power supply should be cut off.

Unit internal cleaning: if the unit runs for a long time, in order to ensure the refrigeration effect, the machine must be cleaned once every 1 or 2 months;

Cleaning steps of environmental protection air conditioning:

1. Clean the air filter and flush it with running water. Prevent blocking, damage to the motor.

2. Clean the environmental protection air conditioning sink, open the drainage valve, and rinse with running water; If there is more dust or debris precipitation, it can be taken out first, and then washed with running water.

3. Clean the evaporative filter, that is, remove the wet curtain from the wet curtain and rinse it with tap water. If there are substances that are difficult to wash on the wet curtain, it can be soaked with tap water first, and then spray the air conditioning cleaning liquid on the wet curtain.

4 environmental protection air conditioning winter or long-term maintenance of the air conditioner first close the water valve, remove the wet curtain, according to the above 2 steps for cleaning, at the same time drain water in the sink, thoroughly clean the air conditioner sink, when conditions can be a comprehensive disinfection. After cleaning, install the wet curtain and turn on the air conditioner fan to supply air for 5-8 minutes. After the wet curtain is blown dry, turn off the main power supply of the air conditioner. It is best to cover the air conditioner with a protective cover outside the air conditioner to avoid external dust and debris into the air conditioner wet curtain.

5, odor removal environmental protection air conditioning use after a period of time, if it does not have the environmental protection air conditioning cleaning and maintenance, the possible causes of the environmental protection air conditioning send the cold wind is faulty, just follow the steps above 3 points at this time cleaning water and water tank, you can add some appropriate hydrogen peroxide disinfection, use detergent to clean water less as far as possible to avoid water damage.

Negative pressure fan is a strong exhaust equipment, can exhaust indoor gas, so that the indoor pressure becomes low, so called negative pressure fan. And positive pressure fan is forced air supply equipment, with negative pressure fan just the opposite.

First, exhaust principle is different:

1. The negative pressure fan exhautes the air to make the indoor pressure drop, the indoor air becomes thinner, forming a negative pressure area, and the air flows into the room due to the pressure difference compensation.

2. The principle of positive pressure fan is opposite to negative pressure fan.

Two, different functions:

1. The main function of negative pressure fan is ventilation, smoke exhaust and peculiar smell exhaust. 2. Positive pressure fan is the fan that points to the air supply in the escape corridor. It sends outdoor wind pressure into the room. When the building fire, will produce a lot of smoke, carbon monoxide and other toxic gases and block the sight, through the positive pressure fan to escape the fire stairs, so that the indoor smoke can not reach the stairs, to create conditions for people to escape.

Three, installation is different:

1. The positive pressure blower is generally installed on the top of the building and linked with the positive pressure air valve of each layer.

2. The negative pressure blower is installed outside the window of the workshop. Generally, the outlet is selected to pump out the air and extract the peculiar smell gas. The positive pressure blower is directed to the air blower in the escape corridor. It sends outdoor wind pressure into the room. When the building fire, will produce a lot of smoke, carbon monoxide and other toxic gases and block the sight, through the positive pressure fan to escape the fire stairs, so that the indoor smoke can not reach the stairs, to create conditions for people to escape.

Evaporative air cooler is delivered to the space by cooling the fresh air, and then the poor quality of the air in the space is discharged, and then reaches the lower space temperature, increasing the effect of indoor air freshness. So the cold air mechanism the cold system is usually one in one out, not all shut down. The data of its air supply pipe are made of galvanized sheet, and sometimes fiberglass and plastic air ducts are also used.

Cooling air supply outlet on the actual needs of the local and the local planning airflow is it drop in temperature to the local air volume, is on the basis of air volume and air outlet velocity to determine standard of tuyere, it is usually use aluminum alloy into product or wood and other products, can choose a variety of ways according to the actual situation of its type can be according to the actual situation in many ways, However, it is best to use dc type four blowing single or double louvers; Install a tuyere conditioning valve in the tuyere to adjust the air volume.

The standard of air supply pipe is usually planned by assuming the method of flow rate. When planning, it is necessary to save money and make the noise and wind resistance smaller, so that the air volume may be larger. The duct bend should not be too bent, so as to reduce resistance. If the duct does not need to be used, it should be shorter. The pipe should be straight as far as possible, and there should not be too many bends and branches, so as to reduce the loss of resistance in some local pipelines of the system. The air supply pipe and the air conditioner should be connected with a soft receiver, and the air supply pipe outside the room should be able to keep heat, and the air supply pipe inside should not matter.

If there is a branch air pipe in the planning, it is necessary to put a valve or air baffle on the branch pipe to regulate the air volume, so that its air volume and the request fit the planned parameters.

Today xiaobian to talk to you about environmental protection air conditioning/cooling fan cooling principle, the main content is as follows:

Environmental protection air conditioning (also called: energy-saving environmental protection air conditioning, air cooler, water cooler, water cooler, industrial air cooler, cooling equipment) is a set of cooling, ventilation, humidification, dust, in addition to taste in a transpiration type cooling ventilation unit. Environmental protection air conditioning has an important feature - energy saving, environmental protection! It is a brand-new environmental protection product without compressor, without refrigerant and without copper tube. The core of the primary component -- transpiration wet curtain and the main motor of 1.1KW/is 8/1 of the power consumption of traditional central air conditioning, which can save electricity for all industries.

Operation principle

Environmental protection and energy saving air conditioner is using water transpiration effect principle, use the method of physical cooling, its use as a cooling medium of the damp curtain, water from the top of the damp curtain uniform flow along the wet curtain corrugated appearance, make from the top to the bottom of the damp curtain even wet embellish, fan convulsions, pressure, force of unsaturated air flowing through the porous wet wet curtain appearance, A lot of humid heat in the air is transformed into latent heat, forcing the air into the room from the dry bulb temperature down close to the wet bulb temperature increases the humidity of the air, making the dry hot air into clean cool air, and then play the role of cooling and humidifying.
