Temperature control is the key to the success of any greenhouse, regardless of its type or scale. For outdoor greenhouse, which is fully exposed to the external environment, extreme temperatures in summer and winter pose significant challenges to crop growth and production efficiency. Similarly, custom greenhouse, designed according to specific user needs and local climate conditions, requires flexible and precise temperature regulation to adapt to diverse cultivation targets, such as high-value vegetables, flowers, or seedlings. Even mini green house, often used for small-scale planting or experimental purposes, needs a reliable temperature control system to ensure the healthy growth of plants. Our advanced temperature regulation solutions, including wet curtain-fan cooling systems, internal and external shading systems, and heating systems, are perfectly compatible with outdoor greenhouse, custom greenhouse, and mini green house, providing a stable growing environment throughout the year.
The wet curtain-fan ventilation and cooling combination is the most economical and effective forced cooling measure for outdoor greenhouse, custom greenhouse, mini green house, as well as livestock houses and high-temperature workshops in summer. Years of practical application have proved that even in extremely hot climates, as long as the wet curtain-fan cooling system is reasonably installed and set up, the indoor temperature can still be controlled below 30°C, creating an optimal working environment for indoor operations and suitable growing conditions for poultry and plants. For outdoor greenhouse, which is directly affected by solar radiation and high outdoor temperatures, the wet curtain-fan system can quickly reduce the indoor temperature, prevent crop wilting and heat damage, and maintain high photosynthetic efficiency. For custom greenhouse that may be used for intensive cultivation of heat-sensitive crops, the system can be adjusted according to specific temperature requirements to ensure the quality and yield of crops. Even for mini green house placed in balconies or small yards, a small-sized wet curtain-fan system can effectively alleviate the high-temperature problem in summer, making it possible to grow crops in hot seasons.
The working principle of the wet curtain-fan system is simple yet efficient. The specially designed hydrophobic wet curtain ensures that circulating water evenly wets the entire wet curtain body, thus ensuring that the surface of the wet curtain in contact with air is completely soaked. Through water evaporation, part of the heat in the air is absorbed by water vapor; at the same time, the axial flow fan installed at the other end of the indoor space operates to form a negative pressure area indoors. This causes outdoor air to pass through the wet curtain and be drawn into the room, while the water vapor carrying high temperature is discharged outdoors, thereby achieving the purpose of cooling. This system is not only energy-saving and environmentally friendly but also easy to maintain, making it an ideal cooling solution for outdoor greenhouse, custom greenhouse, and mini green house. The wet curtain is made of high-quality materials with good water permeability and corrosion resistance, ensuring a long service life even in harsh outdoor environments of outdoor greenhouse.
In addition to the cooling system, the internal and external shading net system is another important part of the temperature regulation system for outdoor greenhouse, custom greenhouse, and mini green house. This system has multiple functions: in summer, when the sun is intense, closing the shading curtain can effectively reduce the indoor temperature, block strong sunlight, and avoid direct radiation damage to crops. In winter, closing the shading curtain at night can effectively prevent the loss of heat inside the greenhouse, playing a role in energy conservation and heat preservation. For outdoor greenhouse, which is fully exposed to the sun in summer and faces severe heat loss in winter, the shading net system can significantly reduce energy consumption and improve the stability of the indoor environment. For custom greenhouse, different shading rates of external shading curtains can be selected according to the types of planted crops, allowing sunlight to enter the greenhouse in the form of diffused light, avoiding crop burns by strong light, and ensuring the rational use of sunlight. For example, leafy vegetables require more scattered light, while fruits and flowers need appropriate direct light; the customizable shading system can meet these different needs. Even for mini green house, a small-sized shading net can be installed to adjust the light intensity, creating a suitable growing environment for different plants.
Our aluminum foil internal shading net (insulation type) is a high-performance product specially designed for outdoor greenhouse, custom greenhouse, and mini green house. It has a shading rate of 55% and an energy-saving rate of 65%, with a standard width that can be adapted to different greenhouse sizes. The aluminum foil material has excellent heat reflection and insulation performance, which can effectively block solar radiation in summer and retain indoor heat in winter. It is easy to install and operate, and can be perfectly integrated with various types of greenhouses, including outdoor greenhouse, custom greenhouse, and mini green house, further improving the energy-saving effect and temperature control precision of the greenhouse.
In most regions of China, greenhouses need heating equipment to ensure the normal growth of plants during winter operation, and this is equally important for outdoor greenhouse, custom greenhouse, and mini green house. We provide two common greenhouse heating methods: hot water heating and hot air heating, which can be selected according to the scale of the greenhouse, local energy conditions, and user needs. Hot water heating uses circular wing radiators, which have the advantages of low operating cost, stable temperature, and economic practicality. It is suitable for large-scale outdoor greenhouse and custom greenhouse that require uniform heating over a large area. Hot air heating is simple and convenient to install, with main equipment including hot air blowers and hot air stoves. It is suitable for small and medium-sized outdoor greenhouse, custom greenhouse, and mini green house, as it can quickly raise the indoor temperature and is easy to maintain and operate. For example, a mini green house used for seedling cultivation in winter can be equipped with a small hot air heater to ensure the seedling emergence rate and healthy growth of seedlings. For outdoor greenhouse in cold regions, the combination of hot water heating and insulation shading net can achieve better heating effect and energy saving.
