The Greenhouse Wet Curtain, also known as the water curtain or evaporative cooling wet curtain, is ingeniously designed to enhance the climate control of your greenhouse. Utilizing the brilliant principle of water evaporation, this innovative device absorbs heat, effectively cooling and humidifying the environment. Crafted from high-quality porous water-absorbing materials, the curtain is strategically placed on the air intake side of the greenhouse, partnering seamlessly with the fan system to create a forceful ventilation process. As the external hot air makes its way through the damp curtain, the process of evaporation absorbs heat, thus lowering the air temperature entering the greenhouse. This not only cools the air but also elevates the humidity levels, creating a nurturing growth environment for your crops, maximizing their potential and yield.
| Evaporation cooling | It achieves air cooling by absorbing heat through the phase change of water (liquid to gas). |
| Ventilation synergy | It needs to be coordinated with negative pressure fans to form air circulation. |
| Humidity regulation | While cooling, it increases air humidity, which is suitable for moisture-loving crops. |
| Energy conservation and environmental protection | Compared with air conditioners, it has extremely low energy consumption and only requires the operation of water pumps and fans. |
| Working principle | System composition |
| 1.Evaporative cooling effect: Water curtains are usually made of honeycomb-shaped water-absorbing materials (such as special paper, plant fibers, etc.). When dry hot air passes through a wet curtain moistened by water, the evaporation of water absorbs the heat in the air, thereby reducing the air temperature (generally by 4 to 12 degrees Celsius). 2. Negative pressure ventilation coordination: The wet curtain needs to be used in conjunction with the fan. The fan extracts the hot air inside the greenhouse, creating a negative pressure that forces external air to enter the greenhouse through the wet curtain, achieving continuous cooling. |
1.Wet curtain wall: Installed on one side of the greenhouse (usually the north or east side), the area is designed based on the volume of the greenhouse and the ventilation volume. 2.Water supply system: It includes water pumps, water tanks, water pipes and circulation devices to keep the wet curtain evenly moist. 3.Fan: Installed on the opposite side of the wet curtain to form air convection. 4.Control system: It can be integrated with temperature and humidity sensors to automatically regulate the operation of water pumps and fans. |
| Core advantage | Applicable conditions | ||
| Energy conservation and environmental protection | It consumes over 80% less electricity than air conditioners and has no Freon emissions. | Climate requirements | It is highly effective in dry and high-temperature areas (such as the summer in the north); The effect is limited in high-humidity areas (such as the rainy season in the south). |
| Low cost | The initial investment and operating costs are relatively low, making it suitable for large-scale greenhouses. |
Greenhouse airtightness | It is necessary to ensure the airtightness of the greenhouse to prevent air leakage from affecting the efficiency of negative pressure ventilation. |
| Increase humidity | Suitable for dry areas or crops with high humidity requirements (such as leafy vegetables and flowers). | Water quality requirements | Hard water needs to be softened to prevent the wet curtain from scaling and clogging. |
| Planting greenhouses | vegetables, flowers, seedlings, etc. |
| Breeding greenhouse | Summer cooling for poultry and special breeding (such as silkworms, insects). |
| Photovoltaic greenhouse | Integrating new energy sources to achieve low-carbon regulation. |
| Installation position | The wet curtain and the fan should be arranged diagonally to ensure that the air flow evenly covers the entire greenhouse. |
| Regular cleaning | Prevent algae and dust from clogging pores (It is recommended to flush once a month). |
| Winter protection | In cold regions, drainage to prevent freezing or disassembly for storage is required. |
| Insect-proof net: | Install insect-proof nets on the outside of the wet curtain to reduce the entry of pests. |
| Increased humidity | Not suitable for crops that prefer dry conditions (such as succulents and some fruit trees). |
| The cooling range is limited | When the temperature is extremely high (> 40ºC), other cooling measures need to be supplemented. |
| Water consumption | Continuous water supply is required. In water-scarce areas, careful selection is necessary. |
| 1. How long is the delivery time? According to your greenhouse size and system, the delivery time is usually 15-60days. 2. Can you supply sample? Small parts can be supplied, but you should pay the express cost. 3. Can your company supply greenhouse design? Our company can give greenhouse design according to your land and plan after deposit. And we can give simple drawing before signing contract. 4. How to install greenhouse ? Firstly we prepare the material and send the material to your city. After your customs clearing, we send 2-4 engineers or all workers to guide to install. If you want to save money, we only send engineers, and you match local workers. If you think it is hard to build the greenhouse, we also can send engineers and workers to install for you. 5. When installing, what cost should we pay? Our engineers and workers visas and round-trip tickets, their foods and accommodation, their communication |
| On-site installation support | Professional technicians are provided to guide the installation and ensure the correct layout of the wet curtain, fan and water supply system. |
| Commissioning service | Adjust the flow rate of the water pump and the wind speed of the fan to optimize the cooling effect. |
| Remote assistance | Guide users to install by themselves through video or text and images (applicable to small systems). |
| 1. Steel tubes are nuded and tied up by wires. 2. Accessories and parts are packed in bags and cartons. 3. All goods are loaded in containers and transported by ship or train |
