Energy saving and environmental friendly air conditioner Ventilation rate reference resources:

General environment The required air change rate is 25-30 times/hour

In public places with crowded people, the required air changes are 30-40 times/hour

yes fever The production workshop of the equipment requires 50-60 air changes per hour

In the wetter Southern region The number of air changes should be increased appropriately, and the hot and dry Northern region The frequency of hot gas can be reduced properly

computing method

Calculation method of unit quantity:

■ Definition of ventilation frequency: ventilation frequency (times/hour)=total indoor air supply volume (m3/h) ÷ (indoor area (m2) × indoor height (m))

■ Number of units used=site volume × air exchange times ÷ unit air volume

■ Post air supply It shall be separately selected according to the actual situation, and the total air volume can be appropriately reduced.

■ Various indoor installation methods

The indoor air supply duct must match the model of the air conditioner. According to the actual installation environment and the number of air outlets, design a suitable air supply duct. Take KS-18 as an example: the length of the installed air duct is 20 meters, and in order to maintain the wind speed, the longer duct is generally reduced.

Environmental friendly air conditioner is also called Air cooler 、 cold air machine 。 The installation of environmental friendly air conditioners mainly includes two parts: the installation of air conditioning host is in the installation of air supply duct; generally, the host is installed outdoors, and the air enters the room through the air supply duct.

Installation method of air supply duct of environmental friendly air conditioner: the air supply duct must match the model of air conditioner, and the air supply duct shall be designed according to the actual installation environment and the number of air outlets. If the air supply distance is required to be within 20 meters, the linear installation mode is generally adopted. In order to maintain the wind speed, when the air supply distance exceeds 20 meters, the variable diameter method is generally used, and the high air pressure and large air volume are used for centralized air supply.

Attention shall be paid to the design of air supply pipeline. In order to make the air supply in the whole space even, the installation interval of air outlet shall be reasonable. The design of air supply duct is based on the pursuit of minimum wind resistance and noise. According to the actual situation, the distribution of work posts shall be considered for directional air supply, and it shall also be noted that the radius of pipe bending radian is generally not less than twice the pipe diameter. Too many branches of the pipeline affect the air supply volume, and the air volume of the branches should be distributed reasonably and effectively. During installation, the air supply pipe should be shortened as much as possible, because the straight air supply is better than the curve.

Outdoor installation mode of environmental friendly air conditioner: in order to make the environmental friendly air conditioner host better play its advantages, do not use return air for operation, but use fresh air for operation. It is better to install it in a well ventilated place, and the middle of the building is the best place for cold air transmission.

Attention should be paid to the installation of the host:

1. Smooth fresh air supply is the requirement of environmental friendly air conditioners for the installation environment. There should be open or semi open doors or windows.

2. The support of environmental friendly air conditioner shall be able to support the weight of the whole body and maintenance personnel, and it is better to use steel pipe welding.

3. The pipeline between indoor and outdoor shall be sealed and waterproof to avoid rainwater leakage. In addition, the power supply is Direct connection For outdoor host, it shall be equipped with air switch 。

Pay attention to the above points during installation, which will effectively improve the use efficiency of environmental friendly air conditioners, save energy consumption, and better enjoy the advantages of environmental friendly air conditioners.

An excellent water Evaporative refrigeration What conditions and indicators should air conditioners have?

Environmental friendly air conditioning engineering drawing

Environmental friendly air conditioning is a necessary workshop equipment for enterprises to recruit workers in the new century. Provide more comfortable production environment 。 Because its unit power consumption is just traditional Air conditioner About one eighth of, which can save enterprises more production costs 。 In fact, no matter what products we buy, quality, brand, after-sales service, price and other aspects will always be our focus, as will evaporative refrigeration air conditioners.

Selection method

In the following contents, we will make specific analysis on these aspects:

1、 Quality should be guaranteed

1. Look at the appearance. The brighter and more beautiful the appearance, the Die precision The higher.

2. Look at the process. When purchasing products, you can check whether the joints are tightly connected, whether the screws, buttons and other small parts used are made carefully, whether they are installed tightly, and whether they are in good contact.

3. Look at the components. The whole machine is precisely assembled by various parts, and the quality of the parts is directly related to the service life and effect of the equipment. Therefore, looking at the main accessories is the most important part in the whole selection process. The main components of the evaporative refrigeration air conditioner are: main Control box ， Blowdown valve ， Water pump motor Fan.

The main control box is equipped with a control circuit board, which is the control system for the whole air conditioning operation. All indicators to ensure the normal operation of the air conditioner are adjusted here. therefore Circuit board design Whether it is reasonable and the quality of the components used will affect its operation effect. however, General consumers It is difficult to identify this accurately. When selecting, you can ask the salesperson about the brand of each component in the product.

Blowdown valve is one of the evaporative cooling air conditioners Key components 。 Because this air conditioner is not used cryogen , is used water circulating pump The water is pumped out uninterruptedly and sprayed evenly through the water distribution system Filter layer The outdoor air enters the evaporative cooling medium CELDEK for full heat exchange with water, and the cool and clean air cooled by water evaporation is forced into the room by a low-noise fan. The function of the blow down valve is to filter and purify the impurities in the circulating water to ensure the effect. High grade drain valve with high precision Electromagnetic element , very sensitive.

The pump motor and fan are the operating power of the whole system. For the motor of evaporative refrigeration air conditioning, the most important thing is to have a good moisture-proof effect; General low-quality motors are prone to leakage, rust and other conditions, and in serious cases, the motor may be burned due to water ingress. In addition, the motor's work efficiency It is also an important aspect of the evaluation that the motor ratio of each machine must be reasonable, otherwise it will affect the working efficiency.

2、 Service should be friendly. Even the best products can't be lost forever Fault operation Good after-sales service is the most effective means to relieve worries. Although it is difficult to see the after-sales service personnel of the manufacturer at the purchase site, service is a simple and effective method from the perspective of the salesperson. Enterprises with independent R&D and production generally have no technical problems in after-sales service. Therefore, Service attitude Is the most important.

An enterprise will management idea ， corporate culture It is fully implemented in the work of each employee. The internal management of enterprises with enthusiastic, energetic and professional salespersons is sure to be strict and effective. Similarly, his after-sales service personnel must be of high quality, and the service content should be followed up promptly.

3、 Brand should have popularity

The brand is created by the combination of product quality and manufacturer's publicity. At the same time, it has strong Brand awareness Our manufacturers generally have long-term strategic plans, and will not make this product today and disappear tomorrow. Therefore, I personally think that brand products are preferred. If the products of famous brand enterprises cannot be guaranteed Famous brand products There is no reason for us to trust. Pay more attention to media reports and evaluations before purchasing products; Such as professional magazines, exhibitions, networks, etc.

In addition, the products must be labeled with national compulsory certification“ CCC ”Mark. Products without this license mark are not allowed to circulate in the market. Enterprises with strict management will also pass the ISO9000 Series, etc certificate of quality system 。 Experts' evaluation of products, and Honorary title They can also be taken into consideration. The certification of the government organ at least shows that the recognition and scale of this enterprise in a certain region is much better than that of an enterprise without anything.

4、 The price should be reasonable

As for the price, I don't think it's simply the price of the product, but more about how much you plan to spend to buy the equipment. Evaporative refrigeration on the market Air conditioning equipment There are many enterprises with full competition and transparent prices. So the same grade product price The difference will not be great. On the contrary, if a product is too cheap, it is worth noting. After all, Production equipment Introduction of, procurement of accessories and materials, Operation management The cost of such products is built with money, and no manufacturer will lose money.

5、 Proper selection

Evaporative air conditioner The purchase of equipment is basically the same as that of other traditional air conditioners: the appropriate model should be selected.

Evaporative air conditioners are suitable for households that need to open, have heating equipment and high temperature heat sources, and air quality High requirements, densely populated, fast cooling Contamination In homes, factories, shopping malls and other places with strong gas or odor, it is necessary to fully understand the choice of evaporative energy-saving and environmental friendly air conditioners Air conditioning installation The actual situation of the site, such as the name, location and structure of the installation site; Then, according to the performance characteristics of different models of air conditioners (such as air volume, air supply distance, external dimensions, etc.) and the actual situation on the site, the selection of smaller ones will not achieve the effect, and the selection of larger ones will cause waste.

Warning:

1. The above items should be strictly observed by the user. The manufacturer is not responsible for any accident caused by incorrect use of the machine. Basic knowledge

What is the core of environmental friendly air conditioning? I wonder if you have known? For environmental friendly air conditioning, the main core is the evaporation filter screen, which is mainly composed of multi-layer corrugated fibers. The actual evaporation area is 100 times of the area of the evaporation filter screen. Rapid evaporation, air and water heat exchange, and air cooling are realized through ventilation system Sent to the machine room, so as to achieve Ventilation and cooling Purpose of

The environmental friendly air conditioner uses ordinary tap water. On the one hand, it can partially recover water resources through some technologies, and on the other hand, it can ensure that the machine room cannot enter water. The cooling range of the environmental friendly air conditioner can usually reach 3 to 15 centigrade The specific cooling range mainly depends on the ambient humidity. The drier the place, the better the evaporation effect and the greater the cooling range

2. Do not refit, repair or move the machine by yourself. The above work shall be completed by professionals, otherwise accidents may occur.

Use cleaning

usage method

join Pool mouth The water should be clean water to keep the air conditioning pipeline unblocked and the water curtain efficient. If the water curtain is found to be insufficient or uneven, check whether the pool is short of water ( Float valve It can automatically supplement and cut off water), whether the water pump operates, and whether the water supply pipeline and water pump enter Water outlet Especially, check whether the small holes on the water spraying pipeline are blocked, and check whether the water spraying pipeline is located in the middle of the wet curtain. For the water curtain+environmental friendly air conditioner Control switch It should be installed indoors. Before use, it should be ensured that there are no sundries in the water curtain and pool. It should be cleaned once or twice a year. When it is not used in winter, the water in the pool should be drained plastic sheeting The box shall be wrapped to prevent sundries from entering the machine and dust

Cleaning method

When cleaning the environmental friendly air conditioner, it is necessary to disconnect the power supply and fold the air plate to prevent someone from misleading the switch and causing danger. Unscrew the screw on the filter screen of the environmental friendly air conditioner, lift the filter screen up, and then filter Shading The filter screen can be removed by pulling out the curtain. Of course, the same is true for the wet curtain.

Carefully remove the four filter screens of the environmental friendly air conditioner, soak them in clean water and then rinse them. Remember not to put any chemicals to avoid corrosion of the wet curtain and filter screen, and the water pressure should not be too high to avoid washing the filter screen and wet curtain.

Cover the environmental friendly air conditioner with a plastic bag and connect the tap water Spray pipe And cleaning port, and backwash the spray pipe with clean water. Rinse the bottom basin of environmental friendly air conditioner with clean water.

Reinstall the four filter screens or wet curtains onto the environmental friendly air conditioner, and then reconnect the Main power supply , in a few minutes Re execution Other operations

Environmentally friendly air conditioners use water circulating cooling air temperature 。 There is a lot of dust in the air. working hours If it is too long, clean the filter screen of the air conditioner host regularly.

1. Disconnect the main power supply of the air conditioner (remove the control board to avoid danger caused by misleading the startup).

2. Unscrew the screw on the filter screen, lift the filter screen upwards, and then pull the filter shading part outward to remove the filter screen (the wet curtain removal method is the same).

3. Carefully remove the eight filter screens (or wet curtains), soak and wash them with clean water (no chemicals can be placed to avoid corrosion of the wet curtains and screen crossing, and the water pressure should not be too high to avoid washing the filter screens and wet curtains).

4. Cover the fan with a plastic bag, connect tap water to the spray pipe and cleaning port, and backwash the spray pipe with clean water.

5. Rinse the bottom basin of the host with clean water.

7. Reconnect the main power supply of the environmental friendly air conditioner, and perform other operations after 5 minutes.

Note: When working at heights, you must wear a safety belt and do a good job of safety.

matters needing attention

When we are using Wet curtain air cooler First, we need to check whether there are dust and other sundries in the pool. It should be cleaned once or twice every year during the service life. The water added to the pool should be tap water or other clean water.

1. The fan is the heart of the wet curtain air cooler. In case of failure, the power supply should be cut off immediately and the electrician should be asked to repair it in time. Pay attention to the grounding wire during installation, and be careful when disassembling the impeller to avoid the deformation of the blade and collision with the box.

2. Float valve of wet curtain air cooler Control failure In case of water shortage or overflow and dripping in the pool, it shall be adjusted or replaced in time.

3. If the water supply for the wet curtain is insufficient or uneven, check whether the pool is short of water, whether the water pump operates, whether the water supply pipeline and the water pump inlet, especially the small holes on the water spray pipeline, are blocked, and whether the water spray pipeline is located in the middle of the wet curtain. The normal spray height shall be greater than 80mm.

4. As the fan of wet curtain air cooler is of low pressure type (static pressure dynamic pressure Therefore, it is no longer possible to extend the duct at the outlet of the air cooler for long-distance air supply.

5. The circuit of the fan and water pump of the wet curtain cooling fan should centralized control The control switch shall be installed indoors.

8. When the air cooler is not used in winter Internal water Put it away, and wrap the box with plastic cloth or cotton cloth to prevent sand from entering the room. Odor resolvent

The first reason is that the environmental friendly air conditioner is not cleaned regularly, and the second reason is that the water quality deteriorates, because the dust accumulates when the environmental friendly air conditioner is used for a long time Strainer Above, it will emit a peculiar smell

1. When the environmental friendly air conditioner is used for a period of time, the filter screen and Copper sheet Dust will accumulate. When there is too much dust, it will produce strange smell, which will seriously affect the air quality and the air volume

2. Because the environmental friendly air conditioner often has some moisture in it after cooling, so after turning off the environmental friendly air conditioner, the environmental friendly air conditioner without dry and mildew proof function will stop immediately, so that the moisture in it will always be there for a long time mould And musty smell.

In fact, it is normal for this phenomenon to occur, not the quality of the environmental friendly air conditioner itself, but the maintenance. When this happens, we just need to remove the dust Erase Clean the filter screen. Pay attention to one thing: the water quality must be good and clean
