The temperature and humidity inside the greenhouse have a crucial impact on the growth and development of crops. Air coolers can lower the temperature inside greenhouses during high temperature periods during the day, preventing excessive temperature from causing damage to crops such as burning leaves and affecting flower bud differentiation. At the same time, it can also regulate the humidity inside the greenhouse, reduce the occurrence of pests and diseases, and improve the yield and quality of crops.

farm

In breeding farms, air coolers are of great significance for the healthy growth of livestock and poultry. High temperature environments can easily lead to heat stroke, decreased feed intake, and slow growth in livestock and poultry. Air coolers can effectively reduce the temperature inside the breeding house and improve the comfort of livestock and poultry. Moreover, the ventilation function of the air cooler can reduce the concentration of harmful gases such as ammonia and hydrogen sulfide in the house, lower the incidence of respiratory diseases in livestock and poultry, and ensure the efficiency of breeding.

Family Domain: Affordable Cooling Options

The application of air coolers in households is also becoming increasingly popular.

In living rooms or bedrooms, air coolers can be used as auxiliary cooling devices. Especially in some well ventilated houses or areas where the summer is not too hot, air coolers can meet people's need for coolness. It can adjust wind speed and temperature according to different usage scenarios, with simple and convenient operation. At the same time, the air cooler has the characteristic of increasing air humidity during operation, which can improve the indoor dry environment for households in dry areas and make residents feel more comfortable.

In short, with its unique advantages, air coolers have been widely used in various fields such as industry, commerce, agriculture, and households, becoming a powerful assistant in creating cool and comfortable environments.

Specific analysis of relevant factors on the price of negative pressure fans

As for the negative pressure fan, the analysis and explanation we want to perform on this product is its price. Because it is an important reference for our selection work, and the appropriate price is selected and the good product quality is guaranteed, then the user has a good price-performance ratio.

    In terms of negative pressure fan prices, the relevant factors are mainly the use of materials, motors, and fan specifications. Therefore, if you want to consider whether the price is appropriate, these factors must be involved and considered. Any of them, so as not to make the selection of negative pressure fan wrong.

    For the selection of the type of negative pressure fan, because it is closely related to the price of negative pressure fan, this work must be paid attention to. So, let ’s take a closer look at its specific aspects.

    Aspect 1: Outer frame material

    The material of the outer frame of the wind pressure fan is generally three types: galvanized sheet, plastic steel and FRP fiberglass. FRP fiberglass is also called glass fiber reinforced plastic.

    Galvanized sheet: its popular name is tinplate. It is used more because it is cheaper. However, there is a major disadvantage in that it has a short service life.

    Plastic steel: Although this material can be used, it is still not common from the current market situation.

    FRP glass fiber: It is a reinforced plastic, which has some advantages of its own, the main one is to have good corrosion resistance and high temperature resistance, and light weight. Therefore, its service life is longer than the above two.

    Aspect 2: Fengye

    For it, it is generally based on the material used. As for the blades of negative pressure fans, the material types are stainless steel, aluminum alloy, aluminum-magnesium alloy, and nylon plus iron. Among them, stainless steel and aluminum alloy are the two more commonly used. The main advantages of aluminum-magnesium alloys are high temperature resistance and high strength. Nylon plus iron is mainly used in some acid and alkali occasions. The price and cost of these materials are different, so the difference in the price of negative pressure fans is caused.

The negative pressure fan has a sharp contrast with traditional cooling equipment

Negative pressure fans are loved by machinery, electronics and other manufacturers for their excellent cooling system! Generally speaking, a regular large-scale processing workshop requires several negative pressure fans to achieve the cooling effect. Compared with the ordinary high-volume traditional cooling system, it can reduce a lot of unnecessary expenses for the company's financial aspect! How much stronger is it than a traditional cooling system? It has always been a topic we are very concerned about, and today is to answer your questions!


    First, traditional cooling equipment basically uses chemical methods to cool down, which is relatively harmful to the human body and is very unfriendly to the environment. The negative pressure fan uses the principle of physical cooling, which has no harm to the human body and the natural environment.

    Second, the traditional cooling equipment is usually slower, and the negative pressure fan has a very fast cooling effect, and the cooling effect can usually be completed in a short time.

    Third, the traditional cooling equipment usually only has a cooling effect, and the negative pressure fan can effectively control the air in the plant when the temperature is lowered, so that the plant maintains relatively fresh air, which effectively improves the mental state of the workers, thereby Can greatly improve work efficiency.

    Fourth, the area under which the negative pressure fan cools is relatively wide. Generally, a 2000 square meter site requires only a few negative pressure fans to complete the cooling effect. This is not comparable to traditional cooling equipment.

    Fifth, the power consumption of traditional cooling equipment is relatively strong, and the power consumption of negative pressure fans is only modest, which is very power saving. And can work long hours.

How does the air cooler refrigeration system achieve energy saving and environmental protection?

With the shoulders of social science and technology, in the aspect of refrigeration, air conditioners and air conditioners have appeared. The cooling effect of these machines is also very strong, comparable to air conditioners. The condensing and evaporating temperatures are also constantly changing, and the cooling capacity of the cooler is also constantly changing. The cooling coefficient is the ratio of the cooling capacity to the power consumption, and is the main economic indicator for measuring the economic rationality of the operation of the air cooler.

Cooler cooling system

    Reasonably adjust the operating parameters of the cooler. The evaporation temperature should generally be 8 ° C to 10 ° C lower than the temperature of the warehouse, and the condensation temperature should generally be 3 ° C to 5 ° C higher than the temperature of the cooling medium. Calculate the cooling capacity of the compressor based on the heat load, evaporation temperature and condensation temperature, and determine the number of compressors to be put into operation. In actual operation, it is generally determined according to the absolute pressure ratio whether to adopt single-stage compression or double-stage compression. Absolute pressure ratio ≥8, using two-stage compression; absolute pressure ratio <8, using single-stage compression.

    Reasonably adjust the intermediate pressure and intermediate temperature. The intermediate pressure and intermediate temperature are related to the condensation temperature, the evaporation temperature, and the volume ratio of the high and low pressure machines. It is worth noting that, in actual operation, the normal liquid level of the intercooler must be maintained. This is not only conducive to reducing the exhaust temperature of the high-pressure machine and preventing the formation of carbon deposits, but also to reduce the temperature of the refrigerant liquid in front of the throttle valve, increase the unit cooling capacity and increase the refrigeration coefficient.

    In the ammonia refrigeration system, the liquid recooling temperature before the throttle valve is generally 5 ° C to 7 ° C higher than the intermediate temperature. The suction temperature of low-pressure machines and single-stage compressors should be 5 ° C to 15 ° C higher than the evaporation temperature.


    The condensing pressure should be compatible with the condensing temperature. If the condensing pressure is too high, check whether the relevant valves of the high-pressure system are open, discharge air and oil, increase the amount of cooling water and cooling air, reduce the cooling water temperature, reduce the heat load, and reasonably configure the condenser.

    The evaporation pressure should be compatible with the evaporation temperature. For air-conditioning systems and medium-temperature and medium-pressure refrigeration systems, the evaporation pressure is generally higher than atmospheric pressure, which helps prevent air from entering the refrigeration system. For places where low temperature is required, a multi-stage compression refrigerator, a cryogenic refrigerator, or a low-temperature refrigeration device can be selected according to the actual situation.

    Pumps and fans used in refrigeration, air conditioning and HVAC projects should be controlled by frequency conversion and PLC new technologies. This is conducive to achieving automatic control of the system, saving energy and reducing operating costs. This advanced control technology is used more in small household air conditioners and commercial air conditioners, and it is slower to promote in large refrigeration and air conditioning projects and heating projects due to the larger equipment investment.
