There are a number of different ways for growers to cool their greenhouses. The best option will likely change from operation to operation based on different factors, like greenhouse size or location.
For larger commercial operations, an evaporative cooling system can provide an efficient and reliable way to cool a bigger growing space. Also known as a commercial swamp cooler, an evaporative cooling system provides powerful cooling ability by employing natural scientific processes. This reduces electricity consumption and allows growers to save on monthly cooling costs, while still creating the ideal greenhouse environment.
1. Determine the type of evaporative cooling system: There are several types of evaporative cooling systems to choose from, including mist cooling systems, pad cooling systems, and wet pad cooling systems. Each system has its characteristics and applicable scenarios. Choose the most suitable type according to your greenhouse size, needs and budget.
2. Install a mist cooling system: The mist cooling system increases the humidity inside the greenhouse by spraying fine water droplets, and reduces the temperature by absorbing heat through the evaporation of water. A spray cooling system usually consists of a water pump, nozzles and piping. Install the nozzle in a suitable position to ensure an even spray of water droplets and avoid over-wetting the plants.
3. Install wet pad cooling system： wet pad cooling system uses wet paper or fiber curtains to achieve evaporative cooling effect through ventilation and air flow. Install cooling pads on one or more sides of the greenhouse, and guide air through the cooling pads through fans or ventilation systems. Make sure the wet curtain is kept wet at all times.
4. Install the wet pad cooling system: The wet pad cooling system uses a moistened sponge or pad and blows air through the wet pad through the ventilation system to achieve the evaporative cooling effect. Install a wet mat near a greenhouse vent or fan, and make sure the mat is kept moist at all times.
5. Control the evaporative cooling system: Control the operation of the evaporative cooling system according to the temperature and humidity inside the greenhouse. Often temperature controllers and humidity sensors can be used to automatically regulate the operation of the system. Make sure the evaporative cooling system is turned on when the temperature is too high, and turned off when the temperature drops or the humidity is too high.
6. Maintenance and maintenance: Regularly clean and maintain the evaporative cooling system, including cleaning nozzles, replacing filter screens, checking pipes and pumps, etc. Ensure that the system is functioning properly and the water source is unimpeded
