In the field of modern agriculture and livestock farming, maintaining precise temperature conditions is crucial for ensuring the health, growth, and productivity of animals and plants. Temperature control equipment, including ventilation equipment such as livestock fans, greenhouse fans, industrial plant fans, circulation fans, and roof automatic ventilation fans, as well as heating equipment like water - heating air heaters, along with core material wet curtain paper and temperature control devices, plays a key role in achieving this balance, especially in regions with extremely variable climates. China has become a major producer of high - quality temperature control equipment, with products supplied to both domestic and international markets. This article will provide a detailed purchasing guide for those interested in Chinese temperature control equipment, focusing on aspects such as product introduction, specification parameters, industrial clusters, major enterprises, and important purchasing considerations.

I. Product Type Introduction: Temperature Control Equipment

Livestock Fans

Livestock fans are specifically designed to regulate air circulation and temperature in livestock barns, poultry houses, and other animal - rearing facilities. They come in various types to meet different needs. Axial - flow livestock fans are widely used due to their high air volume and efficiency. They work by drawing air in parallel to the fan's axis and pushing it out, effectively exchanging the air inside the barn with fresh outdoor air. This helps in reducing humidity, removing harmful gases like ammonia and carbon dioxide, and lowering the temperature during hot weather. For example, in a pig barn with a large population, axial - flow livestock fans can quickly circulate air, preventing the accumulation of harmful gases and ensuring a comfortable environment for the pigs.

Centrifugal livestock fans, on the other hand, are suitable for situations where higher air pressure is required. They operate by drawing air into the center of the fan and then expelling it radially through the blades, generating more pressure. This makes them ideal for use in facilities with long duct systems or where air needs to be distributed to multiple areas. In poultry houses with complex layouts, centrifugal livestock fans can efficiently deliver air to all corners, ensuring uniform temperature and air quality.

Greenhouse Fans

Greenhouse fans are essential for maintaining optimal growing conditions in greenhouses. They help in controlling temperature, humidity, and carbon dioxide levels, which are vital for plant growth. Exhaust fans are a common type of greenhouse fan. They are installed on one side of the greenhouse and work by drawing out hot, humid air, creating a negative pressure that draws in fresh, cooler air from the opposite side. This air exchange helps in regulating the temperature and replenishing carbon dioxide, which is necessary for photosynthesis. For instance, in a tomato greenhouse during the summer, exhaust fans can effectively reduce the temperature, preventing heat stress on the plants.

Circulation fans are another important type of greenhouse fan. Unlike exhaust fans, they do not exchange air with the outside but instead circulate the air within the greenhouse. This ensures that the temperature, humidity, and carbon dioxide levels are evenly distributed throughout the space, avoiding hot spots or cold pockets. In a flower greenhouse, circulation fans help in maintaining consistent conditions, which is crucial for the uniform growth and development of the flowers.

Water - Heated Air Heater

The water - heated air heater is a device specially designed to provide stable heat in livestock houses during cold seasons, which can effectively maintain a suitable breeding temperature. Its working principle is that through a hot water circulation system, the hot water generated by the boiler is transported to the heat - dissipating coil inside the fan. When the fan operates, it draws in cold air. The cold air is heated after passing through the heat - dissipating coil and then blown into the house, thus achieving air temperature rise. This heating method is gentle and uniform, and will not make the air in the house too dry, which can prevent livestock from having stress reactions due to local high temperature or dry air. For example, in a piglet nursery, the water - heated air heater can stably control the temperature at 28 - 32℃, providing a warm and comfortable growth environment for piglets and promoting their healthy development.

Gas - Fired Heater for Livestock

The gas - fired heater for livestock is mainly used for rapid heating of livestock houses in low - temperature environments, and is especially suitable for large - area breeding facilities. It uses natural gas or liquefied gas as fuel, generates heat through the combustion of fuel in the burner, and then the fan diffuses the heat to all corners of the house. It has a fast heating speed and stable heat output, and can raise the temperature in the house in a short time. In cold winter, for large - space places such as beef cattle breeding sheds, the gas - fired heater for livestock can quickly raise the temperature to 15 - 20℃, ensuring that beef cattle are not affected by severe cold, and maintaining normal feed intake and growth rate. However, attention should be paid to ventilation during use to avoid harmful gases generated by insufficient combustion.

Wet Curtain Cooling System

The wet curtain cooling system is an efficient device for regulating the temperature of livestock houses in high - temperature seasons, and is often used in conjunction with fans. Its core is a wet curtain made of special materials. When water is evenly distributed on the surface of the wet curtain, air enters the house through the wet curtain, and the evaporation of water will absorb the heat in the air, thereby reducing the temperature of the air entering the house. At the same time, the fan exhausts the hot air in the house, forming a continuous air convection to achieve the cooling effect. In the layer house in summer, the wet curtain cooling system can make the temperature in the house 5 - 8℃ lower than that outside, effectively alleviating the heat stress of layers and ensuring stable egg production rate. The system can also increase the air humidity in the house, and is suitable for use in arid areas.

Mist Cooling Equipment

The mist cooling equipment reduces the ambient temperature by atomizing water into tiny water droplets, spraying them into the air in the livestock house, and using the principle that water droplets evaporate and absorb heat. Its atomized particles are small, which can quickly mix with air and evaporate, with fast and uniform cooling speed, and will not make the ground in the house too wet. For places sensitive to humidity such as sheep houses, the mist cooling equipment can control the temperature at about 25℃ in high temperature, and at the same time avoid diseases caused by excessive humidity. In addition, it can purify the air and reduce dust in the house while cooling.

Intelligent Thermostat

The intelligent thermostat is the "brain" of the livestock temperature control system, which can realize precise and automatic control of the temperature in the house. It connects with temperature sensors to monitor the temperature in the house in real time, and compares it with the preset temperature range. When the temperature exceeds the set value, it automatically starts or shuts down heating and cooling equipment, such as fans, heaters, wet curtain systems, etc. The intelligent thermostat can also realize remote monitoring and operation through mobile phone APP, which is convenient for farmers to know the temperature situation in the house at any time and make adjustments. In large - scale pig farms, the intelligent thermostat can automatically adjust the appropriate temperature according to different growth stages of pigs. For example, the temperature in the sow delivery room can be precisely controlled at 20 - 22℃, providing the best environment for sows and piglets, reducing manual intervention and improving breeding efficiency.

II. Specification Parameters:Some fan products

The following only introduces some specification parameters of fan - type products. When purchasing fan products for temperature control, several key parameters need to be considered to ensure that they meet the requirements of specific application scenarios.

Air Volume

Air volume, usually measured in cubic meters per hour (m³/h) or cubic feet per minute (CFM), refers to the amount of air a fan can move in a given time. It is a critical parameter as it determines the fan's ability to ventilate a space effectively. For a livestock barn with a certain number of animals, the required air volume depends on factors such as the size of the barn, the type and number of animals, and the desired air exchange rate. For example, a poultry house with 10,000 chickens may require a total air volume of 50,000 - 80,000 m³/h to ensure proper air circulation.

In greenhouses, the air volume requirement is based on the size of the greenhouse and the type of crops being grown. Leafy vegetables, for instance, may require a higher air exchange rate compared to succulents. A 1,000 - square - meter greenhouse growing tomatoes may need fans with a combined air volume of 30,000 - 50,000 m³/h.

Static Pressure

Static pressure measures the fan's ability to overcome resistance in the air flow path, such as ductwork, filters, or obstacles in the facility. It is measured in Pascals (Pa). Fans with higher static pressure are needed when the air has to travel through long ducts or when there are multiple bends and restrictions in the ventilation system. For example, in a greenhouse with a complex duct system for air distribution, centrifugal fans with higher static pressure are more suitable than axial - flow fans.

Power Consumption

Power consumption, measured in watts (W) or kilowatts (kW), is an important factor in terms of operating costs. Energy - efficient fans can significantly reduce electricity bills over time. When comparing different fans, it is essential to look at their power consumption relative to their air volume output. A fan with a higher air volume per unit of power consumed is more energy - efficient. For example, two fans with the same air volume but different power consumption: a 500W fan is more efficient than a 700W fan.

Noise Level

Noise level, measured in decibels (dB), is a consideration for both animal welfare and worker comfort. Excessive noise can stress animals, affecting their growth and productivity. In livestock barns, especially for sensitive animals like dairy cows, low - noise fans are preferred. The noise level of fans should be checked, and ideally, it should be below 70 dB for livestock facilities and greenhouses located near residential areas.

Operating Voltage and Frequency

The operating voltage and frequency of the fan must match the electrical supply in the facility. In China, the standard voltage is 220V or 380V, and the frequency is 50Hz. Using a fan with the wrong voltage or frequency can lead to malfunction, reduced performance, or even damage to the fan motor.

Material and Durability

The material of the fan components, such as the fan blades, housing, and motor, affects its durability and performance. In humid environments like greenhouses and livestock barns, fans made of corrosion - resistant materials such as galvanized steel, stainless steel, or plastic are preferred. Galvanized steel is resistant to rust, making it suitable for outdoor or high - moisture applications. Stainless steel is even more corrosion - resistant but comes at a higher cost. Plastic fans are lightweight and resistant to corrosion but may not be as durable as metal ones in high - temperature environments.

First, clearly define the application for which the fan will be used. Consider the type of facility (livestock barn, greenhouse, industrial plant, etc.), the size of the space, the number of animals or type of crops, and the desired environmental conditions (temperature, humidity, air exchange rate). This will help determine the appropriate type of fan, air volume, static pressure, and other specifications.

For example, in a large - scale pig barn, high - volume axial - flow livestock fans are likely to be the best choice, while in a small greenhouse with complex ductwork, centrifugal fans with higher static pressure may be more suitable.

Quality and Reliability

Choose fans from reputable manufacturers with a proven track record of producing high - quality, reliable products. Check for certifications and standards compliance, such as ISO 9001 quality management system certification, to ensure the fan meets certain quality benchmarks. It is also a good idea to read customer reviews and testimonials to get an idea of the fan's performance and durability in real - world applications.

Energy Efficiency

Given the long - term operating costs associated with fans, energy efficiency is a crucial consideration. Look for fans with high energy efficiency ratings, such as those labeled with the China Energy Label. Energy - efficient fans may have a higher initial cost but can result in significant savings on electricity bills over time.

Noise Level

As mentioned earlier, noise level is important for animal welfare and worker comfort. When selecting a fan, check its noise level specification and ensure it is within the acceptable range for the application. For livestock facilities, in particular, low - noise fans can help reduce animal stress and improve productivity.

After - Sales Service

Choose a manufacturer or supplier that offers good after - sales service, including installation support, maintenance, and spare parts availability. A reliable after - sales service ensures that any issues with the fan can be resolved quickly, minimizing downtime and ensuring the fan operates at peak performance.
